===Hardware enhancements===
+
This page details hardware features which some would like to go into future phones similar to the [[Neo1973]].
  
Some small hardware enhancement could be cheap, but very useful. Please add your ideas/wishes here:

*[[Wishlist - Hardware - Novel Devices]] - openmoko will run on a large number of devices in the future, some of which may be DVD players, cameras, or convergance devices. 
=====Video-capable camera=====
+
*[[Wishlist:Unlikely]] - Hardware that is unlikely to appear in any Openmoko device, due to it being impossible to fabricate with near-term technology, or for other reasons.
*preferably in rotatable turret set into top of unit, so it can face in either direction, making it useful for video conferencing. For a phone to stand a chance in the modern market it will need a camera else it is likely that it won't be bought.
+
*[[Wishlist:Accessories]] - Accessories that people would like, that connect easily to the phone - initially primarily for the Neo1973
 +
*[[Wishlist:Expansion]] - add-ons to the phone, maybe involving hardware changes, and software and hardware protocols to implement these.
 +
*[[CAD models]] - information about the open case models and how to manipulated them yourself in order create custom casings.
  
=====Integrated WiFi hardware=====
+
This page is rather long. Before adding a new idea, please read through this page and the above pages, to make sure your idea has not been suggested before.
*To sync data
+
==Battery==
*To access Internet when WiFi is available (at home, work, school, friends)
+
{{Main|Wishlist/LiFePO4 Battery}}
*For VoIP (this uses much power but maybe the user have the charger connected)
+
**I'm willing to port [http://yate.null.ro/ Yate] to it if the Internet connectivity issue is solved --[[User:Csdexter|@Dexter]] 13:58, 16 February 2007 (CET)
+
*for videoconferencing (as with AccessGrid)
+
*Even 802.11b 11Mbps -only would do -- the point is being able to connect it to the Internet without incurring the (sometimes huge) costs of GPRS or (even worse) HSCSD.
+
*To save power have WiFi able to wake up and check for a designated SSID then sleep again if not found (i.e. I'm not home) or wake up by GPS location (only come up at home and in the office)
+
*Variable TX power, to the minimum needed to connect to the AP.
+
*Some sort of caching (encrypted?) internet proxy that can store and forward packets. Instead of having the radio constantly on, it turns the radio on every 30s, for just long enough to register with the AP, and ask the proxy if it has new packets for it.
+
** An optimisation might be if the hardware, and the AP can do broadcast packets. The receiver is only turned on for .5s/30s, to recieve a broadcast packet saying 'you've got packets' without registering with the AP, or transmitting at all. The GPS synchronises the timing.
+
**This slows the initial connection to the phone, but most tcp/ip applications will not time out in 30s.
+
  
=====LED=====
+
Make the battery independent from SD card and SIM card, so that battery does not have to be taken out when we only want to change either of the cards.
*A blinking LED would be cheap and low power, good for informing the user about new SMS/Email....
+
**An alternative to this would be for one segment of the LCD to be seperately backlit. There are many LEDs in the backlight, all normally on. This has the advantage that you can display reasonable amounts of information on the bit of the screen that's illuminated.
+
**The disadvantage is the field of view is smaller, and it's dimmer than a bare LCD, as the LCD absorbs some light.
+
**This also requires the CPU and LCD to be somewhat active, to keep it refreshed.
+
  
*Note: the LED and button ideas could be combined: illuminated buttons
+
==Processor==
*A yellow LED for GSM/GPRS Tx burst, a blue one for Bluetooth/WiFi Tx burst, a green one for non-urgent notifications (sleep state, missed call etc.) and a red one for urgent notifications (battery almost drained out, new SMS etc.). All of this could be done in one, multicoloured (RGB) LED, similar to the nice one on the Yaesu VX-7R.
+
===A FPGA===
 +
A FPGA is a general purpose reconfigurable logic device.
 +
See [[Wish List - Hardware:FPGA]] for more details.
  
=====D-Pad and Buttons=====
+
===Samsung S3C2443===
 +
*[http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=229&partnum=S3C2443&&ppmi=1427 Samsung S3C2443] Up to 533 MHz, can act as a USB 2.0 device.
 +
 
 +
==Internal Memory==
 +
===RAM===
 +
128MB Dedicated for open files, running software etc., not for storage, or 256MB at all would be really nice and enough for any future software. Using RAM as a swap in unix would significantly speed up the booting process. Approx. 10MB of ram is needed only. The rest, installed software, etc. can be used from ROM sources.
 +
 
 +
===ROM===
 +
Enough to Hold O/S and a fair number of applications and their settings. Persistent Storage with XIP capability. About 128 MB.
 +
 
 +
===Storage===
 +
An internal Micro SDHC should be used for users' files and additional software. Furthermore, user should be allowed to connect to an external USB memory and use it for either a storage or OS purposes.
 +
 
 +
==Wireless data networking==
 +
 
 +
===WiMAX support===
 +
[http://en.wikipedia.org/wiki/Wimax WiMAX] is a high-speed data service, similar to wifi, though longer range and newer. Where service is available, this would complement WiFi. Unfortunately, unlike wifi, frequencies vary worldwide, so global usage may be complex. In South Korea, 2.3Ghz is available for WiMAX, known as WiBro. WiMAX Forum sets heart on 2.5 GHz for global use.
 +
----
 +
Two campuses of the University of California have just completed a deal with a WiMAX service provider to lease UC's ITFS/EBS spectrum to provide WiMAX in the SF Bay Area. Bidding was aggressive between Nextwave, Sprint-Nextel, and Clearwire. Other UC campuses have awarded other contracts throughout California to various of the three contenders. The point here is: these three companies are competing aggressively for spectrum in the 2.5-2.7 GHz range, and it's not limited to CA. At a National ITFS Association meeting in 2005, representatives from Intel said they would be ready to release a WiMAX chipset compatible with these frequencies in 2007, for inclusion in laptops. I assume the folks at [[FIC]] know much more about it that I do! Based on these and other clues, I think WiMAX is coming in the 2.5-2.7 GHz band in the near future... I'll be surprised if I do not see some offerings by early 2009.

 +
===LTE support===
 +
[http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution Long Term Evolution (LTE)] is a high-speed data service, similar to WiMax, but designed to be more compatible with existing GSM systems.  While Sprint & Clearwire are currently testing WiMax deployment in the US, AT&T and Verizon appear to be in preference of LTE.
 +
 
 +
While the project is ongoing and general in scope, it has set itself some specific goals, many of which are oriented around upgrading UMTS to a so-called fourth generation mobile communications technology, essentially a wireless broadband Internet system with voice and other services built on top.
 +
 
 +
===Emerging Protocols===
 +
*[http://en.wikipedia.org/wiki/Near_Field_Communication Near Field Communication] has a few centimeter range, useable for keys, ID badges, pairing bluetooth devices and similar uses. Mentioned in newer bluetooth and SD standards. (No products.)
 +
*[http://en.wikipedia.org/wiki/ZigBee ZigBee] is designed for connecting sensors and switches in buildings, with many options including mesh networks and aggressive power saving compared to bluetooth. (Almost no products available.)
 +
*The [http://en.wikipedia.org/wiki/ANT_%28network%29 ANT network] is for connecting worn devices. Similar to ZigBee, but much simpler and maybe lower power. ([http://www.thisisant.com/?section=9 Short list] of products.)
 +
 
 +
==Camera==
 +
 
 +
* A camera that can take reasonable quality video and pictures is something many want. Applications vary from simple snapping, to gesture interfaces, video conferencing, barcode reading, business card reading, healthcare, servicing, biometric identification, and more.
 +
** Unlike stand-alone cameras, an Openmoko camera could integrate EXIF information from GPS, compass, and internet, making it far more valuable.
 +
 
 +
* Some people can't take cameras into work - a model without the camera, or some way of removing the camera would be useful or leave the camera chip in place and have a removable lens assembly and replacement backcover.
 +
** Ability to a) cover the lens when not in use (to protect it and make it more obvious when you are NOT taking photos), and b) possible "lock" on camera use if a business is providing the phone to its employees. This way the phones are identical in hardware, making it cheaper to produce.

==Display==
 +
===Multitouch screen===
 +
 
 +
''Main article: [[Wishlist:Spell_weaving|Spell weaving]]''
 +
 
 +
See also [http://pogue.blogs.nytimes.com/2007/03/27/the-multi-touch-screen/ this page] containing a link to a video demonstration.
 +
 
 +
A history of multitouch implementations is [http://billbuxton.com/multitouchOverview.html here] ([http://google.com/search?q=cache:billbuxton.com/multitouchOverview.html google cache version])
 +
 
 +
*Use examples: [http://www.youtube.com/watch?v=UcKqyn-gUbY&mode=related&search= Multi-touch interface (from Adobe TED)], [http://www.youtube.com/watch?v=1ftJhDBZqss&mode=related&search= Multi Touch (new touchscreen technology)]
 +
 
 +
===Bigger and better screen===
 +
2.8" widescreen (like in [http://etencorp.com E-ten] PDA/smartphones), or 3.5" widescreen (like in [http://www.expansys.ie/d.aspx?i=134944 Fujitsu Siemens LOOX N560]).
 +
 
 +
262k or 16.7M colurs for displaying images and especially videos.
 +
 
 +
OLED for better contrast, more rich colours, and less energy consumption.
 +
 
 +
Maybe the [http://www.sharpsme.com/Page.aspx/europe/en/part/LS037V7DW01/ LS037V7DW01] by Sharp could be a solution. It has nearly the same specs as the currently used, but 3,7" -- [[User:Wedge | Wedge]]
 +
 
 +
I'd recommend the
 +
[http://www.beck-oled-lcd-tft-display.de/display-datenblatt/typ/tpo/TD035SHED1%20Product%20Specification%20Ver%200.0-112906.pdf TD035SHED1 (Chineese spec paper)] since it has the very same pinout as the current one. Eventually I'm going to create a new case, and will use that display. Alternately the
 +
[http://www.beck-oled-lcd-tft-display.de/display-datenblatt/typ/tpo/TD043MGEB1_v0.4.pdf TD043MGEB1] would be a nice option. However it has 8 bits per channel, and not 6 like the current one, so we would need some adaptor board to connect it: Pull down resistors on the 2 lowermost bits of each channel, and connect the current signal lines to the uppermost bits. Or somehow get 8 bits per channel from the controller.
 +

 +
===="Slightly" Larger Screen====
 +
43mm x 57mm (2.8inch diagonal) is tiny.  A 53mm x 71mm (3.5 inch diagonal) like on the TD035STEE1 would be a nice improvement.  A widescreen format at about 53mm x 82.5mm instead of the 3:4 aspect ratio would be even cooler (if one could be found).
 +
 
 +
====Higher resolution screen====
 +
The current Openmoko hardware has a screen of size 2.8" and resolution 640 x 480 (VGA).
 +
 
 +
See this LCD panel: http://www.engadget.com/2006/12/27/hitachi-does-800-x-480-display-for-phones/
 +
 
 +
At 2.9" it is almost exactly the same size as the current screen but has a wider 800 x 480 resolution (WVGA). This is the same resolution as in the Nokia N800 web browsing devices (but those devices have a bigger, lower DPI screen).
 +
 
 +
A display panel like this would enhance the phones's usability as a small computer, particularly for activities like web browsing, with an almost negligible affect on the size of the device. It would cause slightly increased battery drain though.
 +
 
 +
===Distance sensing touchscreen===
 +
{{Main|Hardware:NearlyTouchScreen}}
 +
TouchKo's (now Wacom Company Ltd.) spatial capacitive "touchscreen", can sense fingers at a small distance, so you do not get your display greasy, and can unlike some touchscreens, be operated with gloves.
 +
 
 +
===<s>Video acceleration</s>===
 +
Hardware acceleration for video playback and 2D/3D accelleration will be present in [[GTA02]].
 +
 
 +
===EPD===
 +
Or electronic paper display, EPD is used in many new devices such as the new Motorola motofone, sonys new e-reader and Irex's iliad. The technology provides thin, lightweight, power saving screens using new eink technology. This technology could cut the weight of the phone and its power usage. For more info see: [http://www.eink.com eink's website].
 +
 
 +
Pro: laserprinter like quality, glossy, very stable image, easy on the eyes. Electronics are similar to TFT. Very low power consumption.
 +
 
 +
Con: Black and grey only (like a newspaper, but glossy), although there were already color prototypes in 2005. low framerate (5fps). Can reflect light (like paper), backlight is impossible.
 +
 
 +
===Transreflective===
 +
It would be nice to have (the option of) a transreflective display, which while being less bright, is readable without needing to power the backlight. Then again, it depends on how much power the backlight uses compared to everything else...
 +
 
 +
===Second Display===
 +
A 32x32 OLED display possibly on the back for camera framing or on an edge so it can be viewed like a pager.
 +
This could be used to display any number of alerts (from any installed software) the alerts could have a dynamic prioritisation which means during the work day a message from the boss has high priority but lower at home (could be GPS/Time controlled?) multiple alerts shrink the icons to a 3x3 grid higher priority messages get more space.
 +
 
 +
===Pico Projector===
 +
[http://www.engadget.com/media/2006/02/digismartphone2.jpg Like the one shown here] or [http://www.youtube.com/watch?v=sT1mhSRichk (video example here)] new cellphones are now coming out with a small, low power projector. This can be used to show movies from your cell phone with 0.5m high image on a while wall for example...
 +
 
 +
Sample Video: http://www.youtube.com/watch?v=sT1mhSRichk
 +
 
 +
Sample Vendor/Product Info: http://www.dlp.com/tech/what.aspx
 +
 
 +
==Input devices==
 +
 
 +
===Tablet PC like pen input (Wacom Technology)===
 +
The Wacom tablet protocol is openly documented, OSS drivers exist. Connection via UART or USB.
 +
[http://www.wacom-components.com/english/technology/emr.html Wacom mobile technology]
 +
[http://www.wacom-components.com/english/product/sensorboard.html Sensorboards]
 +
 
 +
Add a pen holder to the case, suitable for a pen [http://www.wacom-components.com/english/product/pen.html like the "Super Slim Pen" on this page]
 +
 
 +
===Regular phone keypad===
 +
I really like the idea of this phone BUT it misses one
 +
crucial feature - a simple keypad(like most other phones have).
 +
I'd be basicaly happy with a mobile device with a 3-4" screen with a slide out keypad(in a similar way as the n95).
 +
 
 +
===No Dependence on Stylus===
 +
The Neo's basic functionality should be completely usable without a stylus, Like the iPhone but with stylus use for precision work.
 +
 
 +
===QWERTY keyboard===
 +
There should be a model that provides a Palm Treo type keyboard for messaging and internet interface. This would be best implemented in a phone casing with clamshell form factor which would give plenty of room for both button keys and screen area. Lets not just copy the iPhones onscreen data entry and make a phone that is a serious data interface device.
 +
 
 +
===A laser projection keyboard===
 +
Similar to [http://www.thinkgeek.com/computing/input/8193/ this], except the device would be integrated into the phone itself.  Setting the Neo up on a stand on a flat surface (perhaps a stand could be built into the back of the Neo itself, or into a case) would turn the Neo into a micro-laptop.  There may be several issues with the inclusion of this technology, including patents, the space required to project the laser grids, and the power consumption.  If possible, however, it would make text input a breeze.
 +
 
 +
===Just a few more Buttons===
 +
 
 +
2 buttons more, 3 buttons total, mounted sideways would be enough. You could use them for play/pause and loudness controll while the phone remains in your pocket (display locked, ...), reading mails, rss, ebooks,... without wasting display space and so on.
 +
 
 +
With 5 buttons in total you could possibly emulate a keyboard (2^5 = 32 combinations) for those who know how to play a flute. Useable onehanded, not wasting display space and faster than t9. (It's not faster than T9 - I've used this system with the microwriter agenda --[[User:Speedevil|Speedevil]] 00:00, 2 July 2007 (CEST)) Hopefully this is not patented already.
 +
 
 +
===D-Pad and Buttons===
 
*Adding a D-pad (to the bottom of the phone) and 2 to 4 buttons (to the top) would provide some tactile input controls, in addition to the touchscreen. They could be used as shortcut keys in the menu, or playback control when playing media. When the phone is held sideways, they can be used as games controls. (With touchscreen alone, gameplay options are limited)

(With touchscreen alone, gameplay options are limited)
  
=====Accelerometer=====  
+
Game buttons would be best on both sides of the screen. The larger the buttons, the better. 2x 4 buttons in up-down-left-right configuration + some extra buttons separately a bit lower on the device would be good for many for emulation games.
This enables the phone to sense where 'down' is - to enable various options.
+
 
 +
Here is a concept drawing of a possible neo1973 gaming version:
 +
(This has a 4-way direction pad, 8 way may be better for gaming)
 +
<br/>
 +
[[Image:Neogame90.jpg]]
 +
<br/>
 +
Shoulder buttons would be a great addition, too. It would be interesting if there was a total 4 of them, one for every corner. It would make the phone very flexible for rotating and 2 to 6 players playing on one device.
 +
<br/>
 +
:''Note'' : The [http://en.wikipedia.org/wiki/Tapwave_Zodiac Tapwave Zodiac] Palm PDA / Game console hybrid had a similar setup - with an analog stick on the left (also used for quick selection using a radial main menu when working as a PDA), 4 buttons on the right (also configurable for shortcuts when using the device as PDA), and 2 shoulder buttons. Also it had and still has an enthusiastic scene of homebrew development (almost any console emulator for PalmOS can also take advantage of the additional buttons and graphic power of the device). If we also take into account the success encountered by the [http://en.wikipedia.org/wiki/GP32 GP32] in the past and the [http://en.wikipedia.org/wiki/GP2X GP2X] currently on the homebrew scene, it's not unreasonable to plan a future Openmoko device with both a SmartPhone/PDA functionnality ''and'' hand-held console targeting homebrew development.
 +
 
 +
===Touch bigger than display===
 +
If the sensing area of the touch covered the whole front of the phone, buttons could be emulated. Palm used this to have an input area next to the screen.
 +
 
 +
===Thumb keyboard or keyboard attachment accessory===
 +
*Could be slide out or clamshell (hinge on long side) design with an external OLED. The keyboard should be protected when not in use.
 +
*Could be a clip on keyboard that attaches to the serial port or communicates by bluetooth (not preferred for permanent keyboard users).
 +
*Cheap clippable miniusb keyboard
 +
*One of the layouts proposed in [[Hardware:Keyboards]]
 +
* What about virtual keyboard? [[http://www.extremetech.com/article2/0,3973,539778,00.asp Keyboard]]
 +
 
 +
===Analogue Controllers===
 +
 
 +
====Trackball====
 +
A trackball would provide an efficient mouse-like interface in a very compact package.  As exemplified in the newer Blackberry&reg; models.
 +
Maybe instead an optical sensor as are used in mice could be used so that the whole phone can be moved over a surface just like a mouse. (It could function as a Bluetooth mouse for other devices like laptop computers: see [[Bluetooth_Support#Acting_as_HID_device]]. Adding one other two-axis analogue input (possibly just the screen) would make the Neo usable as a TrackPoint or scroll-and-tilt mouse.) The same sensor might be usable as a barcode reader.
 +
 
 +
====Analog Joystick====
 +
A joystick, or [http://www.extremetech.com/article2/0,1697,1772689,00.asp Rollermouse]-like device would provide additional control, compared with touchscreen only.
 +
*A standard [http://en.wikipedia.org/wiki/Pointing_stick pointing stick (ie. TrackPoint)] might serve well. As a fairly standard part, might they be quite inexpensive?
 +
 
 +
====Dual analogues====
 +
Dual analogue controllers (one trackball or joystick above, one below the screen, most likely) might even be feasible. That might be overkill since the accelerometers or touchscreen can be used to provide a second analogue input. But it would be nice to have four axes of analogue control without having to tilt the screen away from you or partly cover it with your hand.
 +
 
 +
===TV/radio receiver===
 +
[[Digital Television]], [[Digital Radio]] or even normal analogue TV/radio is widely available in the world, though unfortunately in various different forms. In markets where one standard is widespread, and hardware is suitable, it would be a great extension of the phone to a general entertainment device for when you're away from home. Multi standard devices would be ideal, but may not be small, low-power, or cheap.
 +
A good start would be an FM tuner, since it's one of the most widely used formats of radio broadcasting in the world.
 +
 
 +
Here's a selection of chips, though it's not clear if the drivers are open source. http://www.sigmatel.com/products/portable/wireless/fmtuner.aspx#fragment-14
 +
http://www.st.com/stonline/products/families/automotive/am_fm_tuners.htm
 +
 
 +
===<s>Accelerometer</s>===
 +
'''Avaliable in GTA02'''
 +
 
 +
This enables the phone to sense which direction 'down' is, and to sense any movements the phone makes.
 +
 
 +
See [[Accelerometer Fundamentals]] for more information on accelerometers as they may be used in phones.
 +
 
 +
In some cases integrated gyroscopes may also be needed. A [[#Digital compass]] can even be of more use since it gives absolute rotation so slow rotations could also be measured. A 3D compass would be nicest, but a simple 2D compass already is a helpful addition to the accelerometers.

+
*Change media player playlist when jogging vs walking.  
*Can't the GPS information be used for that purpose? It should be possible to derive the phone's velocity from the change in coordinates over time, so such a playlist profile switcher should be a possibility even now already. [[User:Abraxa|Abraxa]] 00:09, 18 February 2007 (CET)
+
*<s>Attempt to use to stabilise any future camera.</s> While possible in theory the time required to process the accelerometer signals would cause to much latency, as that it could effectively be used for image stabilisation. You'd have to connect the acceleromters directly to the camera circuits.
**Yeah in my opinion that is a very cool idea. But for that case the device should be much lighter. I wouldn't go jogging with a device with this size.--[[User:Denis std|denis_std]] 01:01, 18 February 2007 (CET)
+
  
=====SIR transceiver=====
+
===Side-Mounted Touch Strip===
*Could be used to detect when to turn off the display (if the low power IR signal is reflected) and activate the key lock. And could be used as a remote. iPhone has a proximity sensor.
+
Add a "touch strip" sensor onto the side of the phone which can be used to scroll. By having it on the side you can use your thumb to scroll comfortably while holding the phone one-handed. An 8-element capacitive sensor would work wonderfully and be easy to fab using either a Quantum QT411 (http://www.qprox.com/products/qslide_qt411.php) or Analog Devices AD7143 (http://www.analog.com/en/prod/0,2877,AD7143,00.html) controller. The Analog Devices chip seems better suited due to it's smaller allowable element size.
*FIR would be nice as well, but I would settle for SIR if it would be added. Linux already has a working IrDA stack so the standard part would be satisfied. I would be more than glad to write lirc thingies for OpenMoko then :)
+
*With the AD7143 you can have an 8-element (128-position) 25mm long strip - Perfect!.
 +
*With a few OLED screens beneath the strip it could be used as dynamic configurable buttons/alerts eg. zoom/flash/shutter with a camera application and SMS/Email/Voicemail alerts in standby
  
=====Standard 3.5mm jack=====
+
===Heart Rate Compatibility===
*I think everyone interested (and knowledgeable) enough to buy a Neo can make a 2.5mm male to 3.5mm female adaptor cable in under 1/2h and under 10EUR :-)
+
  
Certainly - now make it light, small, pretty, durable, tangle-free.  
+
An RF interface to receive data from popular heart rate straps (Polar, Garmin, Sigma, Suunto, etc.). This would go along well with the existing GPS functionality and possible future Accelerometer functionality to make for a full-blown workout tool.
I want a 3.5mm jack. The only problem is - are headsets widely available in the same format as 2.5mm. --[[User:Speedevil|Speedevil]] 14:28, 16 February 2007 (CET)
+
  
=====Multitouch screen=====
+
Software can be written to track heart rate along a running, cycling, skiing, swimming loop, to monitor max and min heart rate, to match heart rate data to GPS coordinates and print map data w/ relevant data.
  
=====Multi I/O adapter=====
 
*VGA, standard Jack (line in & out), standard USB
 
  
=====MMC/SD/SDIO slot (rather than?) miniSD or microSD=====
+
Consider using the heart rate monitor from Zephyr tech.  This communicates over bluetooth and has an SDK available.

A digital compass is useful for orienting maps to the terrain and other location/direction/orientation based applications (... is 300 meter that way) when the user is standing still (regardless of GPS reception) and for following a bearing when GPS reception is poor or speed is low. Also could be used to make the accelerometer data more exact.
 +
 
 +
A compass is also useful for tagging photographs with the correct direction (in addition to location) of the photo.
 +
 
 +
Very small [[I2C]] sensors like [http://www.ssec.honeywell.com/magnetic/hmc6352.html Honeywell's HMC6352 2-Axis Digital Integrated Compass] (6.5 x 6.5 x 1.5 mm) are very appropriate for this. Another option is the much smaller [http://www.global.yamaha.com/news/2006/20060726.html Yamaha YAS529 Three-Axis Geomagnetic Sensor IC Chip] (2.0mm x 2.0mm x 1.0mm).

 +
 
 +
===Thermometer===
 +
An electronic thermometer might become handy for some users.
 +
 
 +
There are very small [[I2C]] devices available, that could easily integrate to the existing bus. For example [http://focus.ti.com/docs/prod/folders/print/tmp100.html this one from ti].
 +
(Could just be cheap and use the thermometer from the battery, thats how they did it in the nokia 5140's). Also is integrated in a barometer/altimeter like the SMD500 mentioned in [[Wish List - Hardware - Atmospheric]].

::But if you carry it in your pocket it is unlikely to show the correct air temperature anyway. [[User:AudriusA|AudriusA]] 17:12, 12 January 2008 (CET)
 +
 
 +
===Barometer and Variometer (Altimeter)===
 +
 
 +
A Barometer measures air pressure. This can be used to give weather information, and also as a variometer, to sense relative altitude. Variometers are commonly used in flying microlight and ultralight aircraft, to get accurate relative altitude.
 +
 
 +
These are also common on high end GPS units. This is a great feature for walkers as you can tell how far you have got on any ascent/decent.
 +
 
 +
See [[Wish List - Hardware - Atmospheric]] for more information.
 +
::The GPS device [[Manually using GPS|outputs the altitude]] as well. This has been tested and works fine. [[User:AudriusA|AudriusA]] 21:44, 7 February 2008 (CET)
 +
:::The precision of GPS altitude is very coarse in comparison with a pressure based altimeter, in the order of 10m for GPS vs 25cm for a altimeter [[User:PTT|PTT]] 10:39, 13 October 2008 (UTC)
 +
 
 +
===Finger print sensor===
 +
A fingerprint sensor gives easy and fast access to the phone, could lock the touchscreen etc. An example of this device can be found at [http://www.sonystyle.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/SY_BrowseCatalog-Start?CategoryName=cpu_VAIONotebookComputers_UX_Series&Dept=computers Sony UX17].
 +
 
 +
Most fingerprint sensors in the embedded market include a navigation mode, where they work similar to either a touch-stick or touch-pad of a laptop.
 +
 
 +
[http://www.fujitsu.com/downloads/MICRO/fma/formpdf/mbf320_fsfin.pdf Fujitsu] has a small strip like reader that has SPI and USB support.
 +
 
 +
===Barcode Scanner===
 +
*less cpu intensive and more reliable than camera+ocr
 +
*though, bluetooth-enabled readers are already available.
 +
 
 +
===Light Sensor===
 +
Ability to sense ambient light, and act accordingly. i.e if it's 3am and LightValue<.1 then Ring Quietly.
 +
 
 +
It can be used to tune brightness of LCD automatically.
 +
 
 +
Can camera be used like light sensor? (when we have camera)
 +
 
 +
===A pluggable sensor module===
 +
Give the option of a composite sensor module consisting of pressure, humidity, temperature and light sensors(if camera not present, which is the case), which will be pluggable to the phone and connected to the USB 1.1 port.
 +
 
 +
===Wheel===
 +
A navigation wheel like on a sony/ericsson 810i would be nice.
 +
 
 +
The wheel could be mounted beside the headphone jack.  In software, it would be appropriate for it to appear as a mouse wheel to applications.  The wheel should also accept a press which emulates a middle mouse button click.
 +
 
 +
Uses for this include:
 +
1. Scrolling lists, with middle button as click/open item.
 +
2. Volume control while talking and in media player.
 +
3. Scrolling pages
 +
 
 +
===Proximity Sensor===
 +
Switch off backlight when you place the phone to your ear. Prevent accidental activation of speakerphone or other sounds when the phone is near the ear (prevent hearing damage). Possibly switch the speakerphone on or off automatically depending on if the phone is by your head or not.
 +
:Automatically turning the speakerphone on/off sounds good, but to avoid disturbing others, for example in public, turning it on could be delayed so for example short looking at the display or putting it to the other ear doesn’t activate it. Additionally/alternatively the delay could be combined with/replaced by a orientation (or motion) sensor, so that it’s not activated when holding it upright, but only when it’s lying e. g. on a table.
 +
 
 +
=== Make ''all'' unlocking of phone, password protected===
 +
 
 +
When my (current non-neophone) phone is in my pocket and I have it locked, it sometimes accidentally unlocks itself since only two keystrokes in the correct order are necessary to unlock it. When it's unlocked and still in my pocket it sometimes calls someone without my knowledge. All phones I've seen today have a press-just-one-button bypass to answer an incoming call even when the phone is locked. I suggest making the locking mechanism let the user configure it so that the user has to enter a password even for answering incoming calls. The likeliness of the phone accidentally runbbing against my car keys, hitting a ten character long password, unlocking the phone without my knowledge and consent is low enough even for us most unlucky users.
 +

 +
===Positioning of Buttons, Connections and ports===
 +
 
 +
Ideally any cable ports such as charging, USB, audio, docking should not get in the way of your hand or fingers when holding it in it's normal orientation. For the sake of SDIO cards an external SD slot should be on the top edge. IR for remote control software and ease of inter-device communication should be on the corner so that it is facing away from you for both orientations. Buttons obviously are positioned for finger control. An example of how '''not''' to do this would be the HTC Universal

=====Thumb keyboard or keyboard attachment accessory=====
+
=== Internal Communication Bus ===
*Could be slide out or clamshell (hinge on long side) design with an external OLED. The keyboard should be protected when not in use.
+
*A standard and/or documented internal communication bus of some sort could simplify adding new hardware modules.
*Could be a clip on keyboard that attaches to the serial port or communicates by bluetooth (not preferred for permanent keyboard users).
+
*Serial USB or I2C connector internal to case towards the top
*cheap clippable miniusb keyboard
+
*Several digital I/O pins that operate at TTL levels
 +
*A few analogue I/O pins attached to a A/D converter
 +
*Documentation of Debug board connector could provide some of this functionality.
  
=====LASER keyboard (can be a full QWERTY keyboard)=====
+
I2C is used on the Neo with some details of resources already in use documented!
*On the hardware side, this would require a $5 laser diode, a $3 (in bulk) custom diffraction grating, and probably a couple of cubic centimetres volume inside the phone.
+
Please see [[I2C | Neo I2C Devices]] for more information & a list of devices & the addresses currently in use & documented for the Neo1973.
*This requires a camera pointable to the front.
+
*It requires an integrated stand for the phone.
+
*To practically use this, you've got to be 40cm or so away from the phone, which means under 25*20 of text resolution.
+
*In software, it's relatively easy to parse the camera output, to find changes in the known laser field.
+
  
There are major problems.
+
===Local Communication===
*Patent issues.
+
*No tactile response at all, which slows typing.
+
*An extra 2cc/6g.
+
  
=====EDGE support=====
+
====USB====
 +
* 5V Powered, to avoid having to carry around a hub for when you want to occasionally plug in a memory stick. Many powered hubs will not recognize a totally unpowered host. Provide a maximum current to drive a basic USB keyboard/memory stick/mouse/webcam/astrowebcam. This could be done by adding a small cheap power converter like the [http://www.national.com/pf/LM/LM2753.html LM2753]
 +
* USB 2.0 (USB 1.1 is too slow to transfer data to the card, removing the card everytime from the phone isn't an option too, because it is placed under the battery)
 +
* '''Standard type A socket''' for quick & easy insertion of memory sticks and all kind of devices. This type of connector is more robust to wear and tear compared to the type B socket which is more prone to break down.
 +
* OTG, to be able connect usb keyboard like [http://www.mobile-review.com/pda/review/cherry-kb-en.shtml Cherry G84-4321 SUNRG]
 +
* Bootable USB device emulation: the possibility to boot any computer on a bootable flagged partition of the transflash.
 +
* Protection against incorrectly wired USB ports: some USB ports are wired incorrectly; if the +5V and GND are swapped, the device would get -5V when it's expecting +5V, which could burn some chips. A reverse-biased diode between +5V and GND, D+ and GND, D- and GND, and (if used) ID and GND, with a low enough forward voltage drop (to limite the negative voltages to what the chips can withstand), would protect the device by tripping the port's short circuit protection.
 +
* 2 USB-Ports; one for acting as USB-host and one for acting as USB-device at same time.
  
=====Ability to insert more than one Sim-Card and (if possible) connect to more than one network at the same time=====
+
====Wireless USB support====
 +
[http://en.wikipedia.org/wiki/Wireless_USB Wireless USB] is the wireless version of USB offering data-rates up to 480 Mbit/s over short distances (<3 meter). Chipsets suitable for a phone are likely to take some time to be available.
  
* This could be achieved via a specialist dual sim card kit (currently on market)- where two sims are trimmed and combined on one card, software support for dual sims would need providing...
+
====Bluetooth with A2DP====
* What about twin-SIMs (SIMs with 2 phone lines registered on them)? Conventional GSM phones have an option to switch between the two, older ones use # (long press before dialling) to do that. I'm guessing Calypso should support it, we just need to provide an interface for it :-) --[[User:Csdexter|@Dexter]] 11:34, 19 February 2007 (CET)
+
Is the blue-tooth radio present in the phone A2DP compatible. If not, make it so.
  
=====RFID tag=====
+
Great for listening to music or watching a movie with full sound.
 +
 
 +
====SIR/FIR transceiver (Serial Infrared) / IR remote control====
 +
*An infrared transceiver is cheap, small, and useful for sync with many laptops and mobile phones.
 +
*Replace/emulate all IR-based remote controls used for your tv, vcr, etc on your neo cell phone.
 +
** replaces multiple 'dumb' devices with a single intelligent device (your neo) that you will probably carry with you at all times anyway.
 +
**Command sets should be retrieved from a database or learned from other less intelligent remote control devices with macros.
 +
**reduces clutter, particularly in the living room.
 +
**inceases the neo's practical status as an 'always-have' device.
 +
 
 +
Other uses.
 +
*Detecting reflections from inside of a caddy, and switching from active mode.
 +
*FIR would be a nice option, as it's some 40 times faster than SIR.

===LED===
 +
*The Neo1973 GTA02 will have LEDs of some sort behind at least one button. [http://lists.openmoko.org/pipermail/community/2007-July/008458.html]
 +
*A blinking LED would be a cheap, low power way to inform the user of new SMS/Email....
 +
**An alternative to this would be for one small part of the LCD to be separately backlit.
 +
**This requires the CPU and LCD to be somewhat active, to keep the LCD refreshed, but gives much more information.
 +
**A Small OLED Screen could be used and display much more information than a LED with minimal power usage.
 +
 
 +
*For example a multicolor LED which pulses yellow for GSM/GPRS transmit, blue for Bluetooth/Wifi, green to indicate non-urgent information - missed call etc, red to indicate battery low or other urgent notices.
 +
 
 +
**The LED and button ideas could be combined: illuminated buttons.
 +
**It must be possible to completely disable the LED to save power or other personal preferences.
 +
 
 +
=== Flashlight ===
 +
For finding keys, or any other application. May also optionally pulse in time with ring, to make phone more visible.
 +
This is really well done in Nokia 5500.
 +
 
 +
-I second this one. The most used feature in my Nokia 5140 after the calling and sms features is the flashlight. It's just one simple LED, but powerful enough to see with if it's really dark. If it ain't dark, you won't need the light anyway. :)
 +
 
 +
Also, Who hasn't lost their keys and opened up their cell phone to use as a flashlight?
 +
 
 +
=== FM transmitter ===
 +
Small FM transmitter to output to car, and other nearby radios.
 +
 
 +
Fix the biggest flaw in the iPod before Apple does!
 +
 
 +
=== Infrared Transmitter w/ universal remote software ===
 +
Infrared LED on top of device with universal remote software so you can control televisions, DVDs etc.
 +
[http://www.novii.tv/ Here] is an example of universal remote software.
 +
 
 +
:I'd like to add that i fully support this. An IR port on future openmoko devices capable of controlling set-top boxes like TV/DVD/Stereo is necessary to make the device as universal as possible. A cellphone should be your window to the world and allow you to interact with it in as many ways as possible.
 +
 
 +
:Care must be taken to use the correct type of IR chipset/controller in the phone. Most IR ports you find on devices like computers, some cellphones etc. Are for high speed data communication and CAN'T control TVs/DVDplayers/Stereos etc.
 +
 
 +
:In order to reduce cost it maybe possible to use the sound chipset in the phone to generate the waveform sent to the IR led. IR remotes work at ~38Khz which is within the range of the sound chipset. The sound output could be internally switched between the IR led or the speakers.
 +
 
 +
===HAC Compliance===
 +
[http://quux.wiki.zoho.com/WhereAreHACphones.html Here] is some summary/discussion of how hearing aid compliance rules work in the US. Specifically it would be nice to see the phone include a [http://www.hearingresearch.org/Dr.Ross/telecoil_and_telephones.htm telecoil], which allows the phone to connect wirelessly to many standard hearing aids.
 +
 
 +
==Mobile Communication options==
 +
 
 +
===Generic Access Network / Unlicensed Mobile Access===
 +
This technology requires cooperation from the cellular provider, but [http://en.wikipedia.org/wiki/Unlicensed_Mobile_Access UMA/GAN] is already offered by T-Mobile in the United States, and perhaps others in other countries.  Allowing the user to roam from GSM to wifi, this technology can save the end user a significant amount of money, and also allow the user to deploy coverage where there was none before.  There are only a few UMA capable phones currently, but it would be great if this could be made to work on a phase 2 type Openmoko device.
 +
 
 +
Note that this features requires more advanced access to the GSM modem.
 +
Special messages needs to be exchanged with the network.
 +
 
 +
===Faster/better mobile connectivity.===
 +
[http://en.wikipedia.org/wiki/Gsm GSM]/[http://en.wikipedia.org/wiki/GPRS GPRS] is at best slow. An incremental improvement would be a radio with [http://en.wikipedia.org/wiki/EDGE EDGE ] support. EDGE is an evolved GSM standard and, like GPRS, it operates on the same frequency as voice. This means a quad-band EDGE radio will have near-complete worldwide coverage.
 +
 
 +
[http://en.wikipedia.org/wiki/UMTS UMTS] - which is widespread in Europe and being deployed in the US, [http://en.wikipedia.org/wiki/HSDPA HSDPA] (asia) and any other mobile standards would be nice for faster data connectivity and coverage.
 +
It is unlikely that all of these will be supported initially, but it is a goal. These faster standards operate in different frequencies from GSM/GPRS/EDGE. Which frequency exactly will depend on the carrier and country. For UMTS in the US, AT&T uses 850/1900 MHz but T-Mobile will use 2100/1700 MHz for example.
 +
 
 +
Until that goal is reached, it is likely that some phones will be brought out for various specific markets - Europe, Asia, US.
 +
 
 +
===Ability to use multiple SIMs/networks===
 +
* External SIM sockets are widely available in China, a dual external socket would be a very good solution.
 +
* [http://www.fonefunshop.co.uk/dualsim/digital.htm Dual SIM card kit] - two SIMs are trimmed and combined, software supportwould be needed, and both can't be used at once...
 +
* Some networks support multiple numbers on one SIM. Unfortunately this won't allow split networks.
 +
* A second/dual GSM module would allow full use of both sims at all times.
 +
* As a hack, [[Bluetooth_powered_Multi-SIM_support | use another mobile via BT]].
 +
** As many as three SIM slots would be genuinely useful, especially for a 3G phone - some 3G data tariffs are only available on data-only SIMs. A user could quite reasonably have one SIM for data, once SIM for his personal voice calls, and a third SIM for his business number.
 +
* Dual SIM card support will be especially welcome by the women. They just love to talk on the phone.
 +
* Save the contents from several SIM-cards to memory and simulate them.
 +
 
 +
===PMR446/FRS Radio===
 +
* Include a PMR/FRS Radio.
 +
* A two-way walkie talkie lets you use the phone to communicate with friends without requiring a GSM connection (crowded networks at festivals, at locations with no GSM coverage).
 +
 
 +
2 way talk over Sprint/Nextel/Boost networks if possible. At least the walkie talkie feature for sure. It's very annoying being at a lake with no service and can't call your friend in the other boat across the lake.
 +
 
 +
===[[DECT]]===
 +
* Include a [[DECT]] GAP/CAT-iq transceiver so you can use your home and/or office PSTN line
 +
** Ability to use Alcatel phonebook stuff (like provided by the eventphone.de phone equipment) would be very nice too
 +
 
 +
===[[SIP phone]]===
 +
Make stripped down (and thus cheaper) version of the Neo1973 phone for use as a SIP phone. Remove GPS, GSM, accelerometers, stylus.
 +
 
 +
Addition of an centimeters-precise location system [http://en.wikipedia.org/wiki/Real_Time_Location_Systems RTLS] would be nice, as it will allow highly sensible indoor context detection. Imagine putting the phone next to your mirror (where you shave daily) and watch it automatically switch to news radio channel. Or put it next to your bed and see it automatically switch to "sleeping" mode, when only calls from predefined numbers are accepted.
 +
 
 +
=='''Casing'''==
 +
See also: [[Alternate Neo1973 case designs]] for a list of cases being considered for design/manufacture by the community.
 +
 
 +
=== Generic Back Plate Connector ===
 +
If the Neo had a few connectors below the back plate, it would be much easier to develop custom backplates. Connectors needed would be GND, Power-out, Power-in (for charging/expansion battery appliances), some bus (either USB or some other bus, maybe usb wouldn't be the best choice since having a backplate and an upstream connection at the same time might cause problems) and maybe some ID pins to discern battery/charger/generic expansion modules on hardware level

 +
Longer case (150-160mm+) with space in the top to put expansion modules, including test & hobby hardware.  Would require use of a standard internal power & communications bus. Could be left empty with blank cover or house cameras, solar panels, a crank powered charger, special transmitters/recievers, or anything else imaginable.

Replacement backs with additional features ranging from solar power, larger batteries, extra hardware, ...
 +
 
 +
===[[Hardware:Neo1973:Alternate_Cases:Expansion_Front_Casing|Expansion Front Casing]]===
 +
Replacement fronts with e.g. extra buttons.
 +
 
 +
===Clamshell Casing===
 +
The clamshell form factor is much preferred by many in that: 1) it provides more area for both screen and keypad 2) its easier for one handed use, the buttons arent crammed in the bottom of the casing 3) clamshell open up to provide longer distance to cover both ear and mouth so you dont have to shout in noisy areas to be heard because the speaker is up on the side of your face 4) clamshells protect the screen from scratches
 +
 
 +
=== Space efficient Lanyard ===
 +
The hole at the bottom of the phone takes a lot of space. A [http://en.wikipedia.org/wiki/Kensington_Security_Slot Kensington Security Slot] could be used instead.
 +
 
 +
=== Rugged version ===
 +
We need something you can drop from 4 feet in to a puddle of dirty water on construction site. Sunlight readable display, maybe aluminium case. The big ugly pseudo military version. What about a casing similar to the OLPC project's in terms of dust and waterproofing? I frequently have to answer the phone with hands dripping sea water and most phone's do not take kindly to that type of treatment. Also the accelerometers can be wired to a protection mechanism which suspends all processing/data activity in case of a (free) fall.
 +
 
 +
*Seconded. Would get one at once. please IP68 and with rubber coating.
 +
*I support this too. Might make more sense as an accessory which you can snap/peel onto your phone however?
 +
*I'm eager to see a ruggedized version, maybe even floatable.
 +
*+1. No point in having an excellent phone/PDA-device, if you can't take it with you where ever you may go. I think this might work as an optional accessory case design, as a previous contributor mentioned.
 +
 
 +
=== Transparent ===
 +
Make a transparent, see-through casing. Why do we need a closed casing for open hardware and open software? Show the world it is a truly Free/Open source phone.
 +
 
 +
That makes sense to me. I second that idea!
 +
Me, too!
 +
+1 :) i would buy one!
 +
 
 +
=== Blank ===
 +
Even though the transparent case would work too, I would like to see a blank case of pure black or white so people could have the option of air-brushing,painting or even drawing on the case.
 +
 
 +
===Integrated solar charger===
 +
Perhaps on one side there could be an integrated photovoltaic. It would be small, but might it be enough to charge the device. It could be integrated in an aesthetically pleasing fashion like [http://i.i.com.com/cnwk.1d/i/bto/20080523/solarboat.jpg this]... except, with a matching color. :)
 +
 
 +
===Custom look===
 +
Provide a service which offers custom case design like [[Freerunner_Alternative_Case_Designs|this one]], see images below. Just upload two images, reposition them in an interactive website, submit credit card information and the custom case design with application manual will be shipped to you.

==Misc==
 +
===Battery Size/Standby Time===
 +
 
 +
Since the device will be ultimately running a wide selection of software on it the battery needs to be somewhat more robust and have a longer standby time than that of current phone's. At the moment I'm using a Moto (2 days before charging) or a Samsung (3 days before charging) and am not impressed with either phone's standby time, and I'm not using the phone's for anything but calls.
 +
 
 +
=== Dedicated Power / Charger Pinout ===
 +
 
 +
Having not yet seen a physical Neo device, I haven't been able to examine any of the IOs to see if there already is a dedicated power / charger input. However, I can imagine that it might be very tempting to have the device charge solely via USB. For any device that is capable of USB-host, that is a '''horrible''' idea, particularly when it's intended to be a mobile-komputing device.
 +
 
 +
Since the device is able to run in USB host mode, it might be a good idea to allow for an alternate power supply, if say, a USB keyboard was being used for several hours. Rather than drain the battery, one could just supply power via the wall outlet while still providing endless hours of USB-host enjoyment for those hard-coders on the go.
 +
 
 +
The main question is just deciding on where to take power from (or at all) if in USB-client mode and the power cable is inserted, but really, that's not too big of a deal and can be solved with very minimal circuitry. If 5V is detected on the power line, then the obvious place to get it from is there at any point in time.
 +
 
 +
This might sound extraneous at first, but when the device shuts down in the middle of an important USB file transfer, or right before that great piece of code was saved, you can bet that those users will be saying "Hmm... a separate power adapter would have really come in handy right now".
 +
 
 +
I suggest a tiny 3mm, dedicated +5V power input (something a la Nokia).
 +
 
 +
With the dedicated charger it would also be possible to use any standard USB device if
 +
the phone recognized the external power and enabled 5v power when plugged in.
 +
 
 +
===Galileo/GLONASS/GPS receiver===
 +
*A multi-standard satellite positioning module would be nice eventually, it does not seem to be near-term due to chipset availability problems. Galileo is the to be launched (2011) European positioning system. GLONASS is the already existing Russian one.
 +
 
 +
=== GPS antena ===
 +
The current GPS device seems even dependent on weather and may not work in heavy rain or snow. It seems necessary to think how to improve the reliability. The small portable GPS antena may be an option.
 +
 
 +
===X10 RF Remote===
 +
Many PC-based media centers are being equipped with an RF (433 MHz) / X10-based remote control. The [http://en.wikipedia.org/wiki/X10_(industry_standard) X10] protocol also facilitates home automation to control lamps, switches, etc.
 +
The advantages of using RF for control instead of Infra-red this that it also works when furniture, walls, or doors are blocking the path between RF remote and the equipment or device. [http://www.lirc.org/ Lirc] supports X10-based RF remotes (but expects having an USB RF receiver attached to the media center).

* Implementation/Cooperation with: [http://www.rfidguardian.org/ RFID-Guardian]
*Advantages of a RFID tag? I would see a lot privacy problems
+
*An enable-able tag would be of use - for example being able to use the phone to open doors, or cars. Unfortunately, it's moderately hard to do secure programmable tags that are compatible with existing systems, for obvious reasons.
**The tag could be switched on or off. A nice feature would be a module able to clone tags. This would unfortunately probably be rather expensive.
+
* Say you have RFID tags on your personal belongings: cellphone, keys... Neo could be programmed to remember the last recorded GPS location before it lost contact with the respective RFIDs. It'd be trivial to check where you left your cellphone, get directions from a map...or beep when the phone gets out of RFID range.
**What about an RFID Reader which could be used to locate items with RFID tags (IE: in your house) [[User:Alexpb|Alexpb]]
+
***That would be a nice feature--[[User:Denis std|denis_std]] 08:33, 17 February 2007 (CET)

***Most tags can only be located within 10cm or so. Essentially no cheap tags can be located over several metres.--[[User:Speedevil|Speedevil]] 13:17, 18 February 2007 (CET)

===== USB 2.0 =====

*I agree with this idea, a great idea and you have to do it (Jackcday)
* Powered
+
*Or, a python script that use the accelerometers and rfid reader, so when the phone moves it checks for an rfid tag (that would be in the users pocket) and if it doesn't get a response it rings in full volume, or starts a tracking utility :))))
* Host Mode / Device Mode
+
*A RFID reader would need an antenna loop which could probably be used for wireless docking or even charging
* OTG
+
*connected RFID UHF Reader to the openmoko via USB Host Mode [http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5612279 http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5612279]
 +
* some hardware project is there: [[Freerunner_RFID_Board]]
  
=====UMTS support=====
+
===NFC chip===
 +
*A Near Field Communication chip, with this chip it will be possible to pay with your phone (like a credit card)in the near future, see [http://www.nokia.com/A4305081 Nokia]for details
 +
*NXP is a chip fabricator which provides NFC chips [http://nxp.com NXP] direct link>> www.nxp.com/#/pip/cb=[type=product,path=/53420/53424]|pip=[pfp=53424][0] their chips also support the above RFID reading
 +
*a technical note: NFC is an extension of RFID where two readers can communicate with each other i.e. both are quite similar
  
=====Dump the '''''egg-shaped''''' case design and go '''''rectangular''''' for more screen space=====
+
===Less weight===
*I'm all for devices that look great and have great features - aside from that I really like the current design. Thus I'd like to comment that the design change request is probably not the majority's opinion. [[User:Abraxa|Abraxa]] 00:00, 18 February 2007 (CET)
+
* Work on the weight of the Neo1973 and following devices. At the present time the Neo1973 is just a moderate / normal business or multimedia phone. The ordinary "user" may want something lighter. Take a look at the following table, that's the Neo1973 compared with other common business or multimedia phones.
 +
{|border="1"
 +
| Neo1973 || Fujitsu-Siemens LOOX N560 || E-Ten Glofiish X500+ || Sony Ericsson P990i || iPhone || Nokia E65

|  184 g  ||            160 g          ||        146 g        ||        150 g        ||  135 g ||  115 g 
 +
|-
 +
|}
  
=====A standard slip-on or clip-on template (possibly with buttons) to make the touch-screen blind accessible=====
+
===Make it smaller===
 +
* To stay within physical matters: Maybe the Neo1973 is also just a normal business/multimedia phone when looking at the size. It would be great the shrink it a bit. Especially the thickness of 18.5 mm could be worked on!
  
=====Speakerphone functionality=====
+
===Standard 3.5mm headphone jack===
 +
The Neo1973 uses a 4-conductor 2.5mm jack for stereo headphones and a microphone. A 2.5mm jack is the most common for headsets.
  
=====Reposition Speakers=====
+
There is an emerging convention used in the Nokia N800 and some other devices. A 4-conductor 3.5mm jack that can use a microphone with special headsets, but can also be used with off-the-shelf 3.5mm stereo headphones. Adapters to 2.5mm are of course available and this 3.5mm jack is much more robust.
* putting the two speakers on opposite sides of the screen would make the stereo sound much more effective
+
  
The screen is 2.8" across.
+
Neglecting space limitations, multiple sockets - 2.5mm and 3.5mm would be nice. Probably not practical in a phone. Other expanded plugs might allow remote controls.
That's not especially effective.
+
Also, the speaker noise does come out the side - look at the grills in the pictures. --[[User:Speedevil|Speedevil]] 06:19, 16 February 2007 (CET)
+
  
=====Small metal frame for protection (like Siemens M65, only with more style)=====
+
Other uses might be better met using bluetooth, or USB audio.
  
=====Free GPIO ports on a connector to allow easy, simple hardware extensions=====
+
===Software should know of the jack status===
 +
It should be possible for the OS to see if there is something connected to the audio jacks. That would avoid the embarrasing moments when you accidently pull out the headphones from the cell/laptop and whatever you were listening blares over the place at full volume. If OS can see, that the headphones were unplugged without turning off the audio, then it could pop up a warning that would allow to direct audio to internal speakers or turn it off. If the user would replug the headphones/speakers then the warning would dissapear as well.
  
=====Video acceleration=====
+
===Laser Pointer===
Hardware acceleration for video playback.
+
Include a built in laser pointer.  Everything is better with lasers.
  
=====3D acceleration=====
+
Make it a green one <10mW so it won't be illegal in quite a few countries.
3D hardware acceleration for 3D games, GUIs, etc. (maybe a PowerVR MBX Lite ?).
+
  
=====Alcohol Sensor=====
+
===Completely free hardware===
Alcohol sensor adjacent to microphoneIt doesn't have to be accurate, just has to detect any amount of alcohol on the speaker's breath.  I understand this is a very narrow market, but alcohol is on every parent's mind.
+
Consider selling one device with absolutely no non-free components in it, even if that means dropping the GSM supportI believe having one such device available would be good, because then it could be recommended by organizations like the FSF which typically never recommends anything if it has even a little non-free code in it.
  
 +
=== Consider economy / inexpensive / less featured edition ===
 +
Some people want less features, because they do not need them. Leaving out some features either lets the phone get smaller or possibly enhances battery live.
  
=====Disinfection UV-Light=====
+
One big suggestion in this area is a b/w lower res display instead of the big color display.
I had read about it in an Article on http://www.americanairandwater.com/UV-news/. But Motorola patents it.
+
Yes - finally a way to stop the billions of annual deaths due to cellphone infections! --[[User:Speedevil|Speedevil]] 14:04, 16 February 2007 (CET)
+
It´s just something that flying in my head... It´s not the first "unreal" or "useless" idea. Just for fun! --[[User:MookiE|MookiE]] 14:51, 16 February 2007 (CET)
+
  
More seriously - UV of the required frequency is inherently eye-damaging.
+
=== Inductive Charger ===
Also, as I understand it, there are actually no UV LEDs that will reliably produce 'germicidal' UV.
+
The most expensive - and they are very expensive - ones produce UV of a sort that may kill very susceptible bacteria, but comparatively few.
+
IIRC the LEDs are $20 per.
+
--[[User:Speedevil|Speedevil]] 15:11, 16 February 2007 (CET)
+
  
=====Teleportation=====
+
It would be nice if it was possible to charge the phone without having to connect a cable. I'd like to have a simple docking station with an inductive charger like the type that's used for electric toothbrushes [http://home.howstuffworks.com/question292.htm ]. The charger itself could get its power from a standard wall-wart power supply, or it could be USB/Firewire powered.
Implementing a beaming-device to the Neo would make it the first phone enabling teleportation.
+
See: [http://news.bbc.co.uk/1/hi/sci/tech/3811785.stm]
+
Possible implementation difficulties might be the lacking teleportation-support in the GSM standard as well as uncooperative mobile service providers that feel uneasy towards innovative technologies...
+
  
=====EPD=====
+
==== Examples of existing commercial systems ====
 +
* http://www.splashpower.com/
  
Or electronic paper display, EPD is used in many new devices such as the new Motorola motofone, sonys new e-reader and Irex's iliad. The technology provides thin, flexible, power saving screens using new eink technology. This technology could cut the weight of the phone and its power usage. For more info see: [http://www.eink.com eink's website].
+
*might be combinable with a RFID reader
  
=====FM/Digital Radio(DAB) Reciever=====
+
=== Solar panel/dynamo Charger===
  
A nice feature would be a radio reciever: FM or even better: [http://en.wikipedia.org/wiki/Digital_Audio_Broadcasting Digital Audio Broadcast] (Digital Radio)
+
It would be very nice to be able to charge the phone outside of the electric grid (for example on hikes and boating trips). A combined solar panel and muscle empowered (rotational etc.) charger would do the trick nicely.
 +
* It might be possible to include a charger based on a step motor and an excentric weight, similar to automatic wrist watches. Charge by walking/running, if that wouldn't be cool...

- I think a dynamo charger ("share charger", rotational, ...) would be more practical as a peripheral, connected through the USB-interface using the same principle cellphones now charge when connected to an USB-port.

Solar cells from Plastic, on the reverse side of the Neo 1973

 +
=== Vibration===
 +
Instead of using a counter-weighted motor to provide a vibrate function, a small solenoid could be used.It would provide more of a tap or click feel. It could be used to provide feedback when a on screen button is pressed. Different patterns of taps is a lot easier to recognize compared to different vibration frequencies. For those who know morse code they could have the phone tap out the phone number/name of the person calling/messaging or other alerts.
 +
 
 +
===As plug-in without screen...===
 +
 
 +
Along the lines of add-on cards, only looking at it from a different angle, I'd like to see a "faceless" openmoko with a documented hardware interface for both communicating with it and inserting it into other devices. Even the keypad/screen/battery would be attached, openmoko itself would just be faceless sliver of hardware with a documented interface and an API for communicating with the innards.
 +
 
 +
===Running without battery===
 +
Please make it possible to run the device without a battery inserted (with the charger attached). I have several mobile phones which do not work anymore (even when attached to the charger) because the battery is worn out and new batteries are not available. I want the Openmoko to be usable when the battery is worn out.
 +
 
 +
* Seconded.
 +
 
 +
===Make GSM/CDMA/WiFi/WiMax/GPS plugable===
 +
Please make Openmoko mobile as PC GSM/CDMA/... just working like plugable cards, they are cards/adaptor for the DEVICE only. the user may eject GSM module and inject with CDMA module. the DEVICE may provide several slot to allow user choose wifi/wimax/sd/gps/harddisk/...
 +
 
 +
===Wifi chip that can be used with kismet and other sniffers===
 +
Please change the wifi chip that also can be used for sniffing wifi connection preferably the latest standard, not N. For pen testing. A wifi chips like the [http://www.ralinktech.com/ralink/data/RT2800.pdf RT2800] I think?
 +
 
 +
===Add a connector for an external Wifi aerial===
 +
PLease can a an external aerial connector be added so better arials can be used useful for sniffing wifi connections for pen testing etc.

Latest revision as of 13:52, 6 April 2011

This page details hardware features which some would like to go into future phones similar to the Neo1973.

Related pages are:

  • Wishlist - Hardware - Novel Devices - openmoko will run on a large number of devices in the future, some of which may be DVD players, cameras, or convergance devices.
  • Wishlist:Unlikely - Hardware that is unlikely to appear in any Openmoko device, due to it being impossible to fabricate with near-term technology, or for other reasons.
  • Wishlist:Accessories - Accessories that people would like, that connect easily to the phone - initially primarily for the Neo1973
  • Wishlist:Expansion - add-ons to the phone, maybe involving hardware changes, and software and hardware protocols to implement these.
  • CAD models - information about the open case models and how to manipulated them yourself in order create custom casings.

This page is rather long. Before adding a new idea, please read through this page and the above pages, to make sure your idea has not been suggested before.

Contents

[edit] Battery

Main article: Wishlist/LiFePO4 Battery


Make the battery independent from SD card and SIM card, so that battery does not have to be taken out when we only want to change either of the cards.

[edit] Processor

[edit] A FPGA

A FPGA is a general purpose reconfigurable logic device. See Wish List - Hardware:FPGA for more details.

[edit] Samsung S3C2443

[edit] Internal Memory

[edit] RAM

128MB Dedicated for open files, running software etc., not for storage, or 256MB at all would be really nice and enough for any future software. Using RAM as a swap in unix would significantly speed up the booting process. Approx. 10MB of ram is needed only. The rest, installed software, etc. can be used from ROM sources.

[edit] ROM

Enough to Hold O/S and a fair number of applications and their settings. Persistent Storage with XIP capability. About 128 MB.

[edit] Storage

An internal Micro SDHC should be used for users' files and additional software. Furthermore, user should be allowed to connect to an external USB memory and use it for either a storage or OS purposes.

[edit] Wireless data networking

[edit] WiMAX support

WiMAX is a high-speed data service, similar to wifi, though longer range and newer. Where service is available, this would complement WiFi. Unfortunately, unlike wifi, frequencies vary worldwide, so global usage may be complex. In South Korea, 2.3Ghz is available for WiMAX, known as WiBro. WiMAX Forum sets heart on 2.5 GHz for global use.


Two campuses of the University of California have just completed a deal with a WiMAX service provider to lease UC's ITFS/EBS spectrum to provide WiMAX in the SF Bay Area. Bidding was aggressive between Nextwave, Sprint-Nextel, and Clearwire. Other UC campuses have awarded other contracts throughout California to various of the three contenders. The point here is: these three companies are competing aggressively for spectrum in the 2.5-2.7 GHz range, and it's not limited to CA. At a National ITFS Association meeting in 2005, representatives from Intel said they would be ready to release a WiMAX chipset compatible with these frequencies in 2007, for inclusion in laptops. I assume the folks at FIC know much more about it that I do! Based on these and other clues, I think WiMAX is coming in the 2.5-2.7 GHz band in the near future... I'll be surprised if I do not see some offerings by early 2009.

-Tzf 21:54, 24 November 2007 (CET)


[edit] LTE support

Long Term Evolution (LTE) is a high-speed data service, similar to WiMax, but designed to be more compatible with existing GSM systems. While Sprint & Clearwire are currently testing WiMax deployment in the US, AT&T and Verizon appear to be in preference of LTE.

While the project is ongoing and general in scope, it has set itself some specific goals, many of which are oriented around upgrading UMTS to a so-called fourth generation mobile communications technology, essentially a wireless broadband Internet system with voice and other services built on top.

[edit] Emerging Protocols

  • Near Field Communication has a few centimeter range, useable for keys, ID badges, pairing bluetooth devices and similar uses. Mentioned in newer bluetooth and SD standards. (No products.)
  • ZigBee is designed for connecting sensors and switches in buildings, with many options including mesh networks and aggressive power saving compared to bluetooth. (Almost no products available.)
  • The ANT network is for connecting worn devices. Similar to ZigBee, but much simpler and maybe lower power. (Short list of products.)

[edit] Camera

  • A camera that can take reasonable quality video and pictures is something many want. Applications vary from simple snapping, to gesture interfaces, video conferencing, barcode reading, business card reading, healthcare, servicing, biometric identification, and more.
    • Unlike stand-alone cameras, an Openmoko camera could integrate EXIF information from GPS, compass, and internet, making it far more valuable.
  • Some people can't take cameras into work - a model without the camera, or some way of removing the camera would be useful or leave the camera chip in place and have a removable lens assembly and replacement backcover.
    • Ability to a) cover the lens when not in use (to protect it and make it more obvious when you are NOT taking photos), and b) possible "lock" on camera use if a business is providing the phone to its employees. This way the phones are identical in hardware, making it cheaper to produce.
  • See Alternate Cases:Camera for phone casing suggestions.

[edit] Display

[edit] Multitouch screen

Main article: Spell weaving

See also this page containing a link to a video demonstration.

A history of multitouch implementations is here (google cache version)

[edit] Bigger and better screen

2.8" widescreen (like in E-ten PDA/smartphones), or 3.5" widescreen (like in Fujitsu Siemens LOOX N560).

262k or 16.7M colurs for displaying images and especially videos.

OLED for better contrast, more rich colours, and less energy consumption.

Maybe the LS037V7DW01 by Sharp could be a solution. It has nearly the same specs as the currently used, but 3,7" -- Wedge

I'd recommend the TD035SHED1 (Chineese spec paper) since it has the very same pinout as the current one. Eventually I'm going to create a new case, and will use that display. Alternately the TD043MGEB1 would be a nice option. However it has 8 bits per channel, and not 6 like the current one, so we would need some adaptor board to connect it: Pull down resistors on the 2 lowermost bits of each channel, and connect the current signal lines to the uppermost bits. Or somehow get 8 bits per channel from the controller. --Datenwolf 12:06, 28 July 2008 (UTC)

[edit] "Slightly" Larger Screen

43mm x 57mm (2.8inch diagonal) is tiny. A 53mm x 71mm (3.5 inch diagonal) like on the TD035STEE1 would be a nice improvement. A widescreen format at about 53mm x 82.5mm instead of the 3:4 aspect ratio would be even cooler (if one could be found).

[edit] Higher resolution screen

The current Openmoko hardware has a screen of size 2.8" and resolution 640 x 480 (VGA).

See this LCD panel: http://www.engadget.com/2006/12/27/hitachi-does-800-x-480-display-for-phones/

At 2.9" it is almost exactly the same size as the current screen but has a wider 800 x 480 resolution (WVGA). This is the same resolution as in the Nokia N800 web browsing devices (but those devices have a bigger, lower DPI screen).

A display panel like this would enhance the phones's usability as a small computer, particularly for activities like web browsing, with an almost negligible affect on the size of the device. It would cause slightly increased battery drain though.

[edit] Distance sensing touchscreen

Main article: Hardware:NearlyTouchScreen


TouchKo's (now Wacom Company Ltd.) spatial capacitive "touchscreen", can sense fingers at a small distance, so you do not get your display greasy, and can unlike some touchscreens, be operated with gloves.

[edit] Video acceleration

Hardware acceleration for video playback and 2D/3D accelleration will be present in GTA02.

[edit] EPD

Or electronic paper display, EPD is used in many new devices such as the new Motorola motofone, sonys new e-reader and Irex's iliad. The technology provides thin, lightweight, power saving screens using new eink technology. This technology could cut the weight of the phone and its power usage. For more info see: eink's website.

Pro: laserprinter like quality, glossy, very stable image, easy on the eyes. Electronics are similar to TFT. Very low power consumption.

Con: Black and grey only (like a newspaper, but glossy), although there were already color prototypes in 2005. low framerate (5fps). Can reflect light (like paper), backlight is impossible.

[edit] Transreflective

It would be nice to have (the option of) a transreflective display, which while being less bright, is readable without needing to power the backlight. Then again, it depends on how much power the backlight uses compared to everything else...

[edit] Second Display

A 32x32 OLED display possibly on the back for camera framing or on an edge so it can be viewed like a pager. This could be used to display any number of alerts (from any installed software) the alerts could have a dynamic prioritisation which means during the work day a message from the boss has high priority but lower at home (could be GPS/Time controlled?) multiple alerts shrink the icons to a 3x3 grid higher priority messages get more space.

[edit] Pico Projector

Like the one shown here or (video example here) new cellphones are now coming out with a small, low power projector. This can be used to show movies from your cell phone with 0.5m high image on a while wall for example...

Sample Video: http://www.youtube.com/watch?v=sT1mhSRichk

Sample Vendor/Product Info: http://www.dlp.com/tech/what.aspx

[edit] Input devices

[edit] Tablet PC like pen input (Wacom Technology)

The Wacom tablet protocol is openly documented, OSS drivers exist. Connection via UART or USB. Wacom mobile technology Sensorboards

Add a pen holder to the case, suitable for a pen like the "Super Slim Pen" on this page

[edit] Regular phone keypad

I really like the idea of this phone BUT it misses one crucial feature - a simple keypad(like most other phones have). I'd be basicaly happy with a mobile device with a 3-4" screen with a slide out keypad(in a similar way as the n95).

[edit] No Dependence on Stylus

The Neo's basic functionality should be completely usable without a stylus, Like the iPhone but with stylus use for precision work.

[edit] QWERTY keyboard

There should be a model that provides a Palm Treo type keyboard for messaging and internet interface. This would be best implemented in a phone casing with clamshell form factor which would give plenty of room for both button keys and screen area. Lets not just copy the iPhones onscreen data entry and make a phone that is a serious data interface device.

[edit] A laser projection keyboard

Similar to this, except the device would be integrated into the phone itself. Setting the Neo up on a stand on a flat surface (perhaps a stand could be built into the back of the Neo itself, or into a case) would turn the Neo into a micro-laptop. There may be several issues with the inclusion of this technology, including patents, the space required to project the laser grids, and the power consumption. If possible, however, it would make text input a breeze.

[edit] Just a few more Buttons

2 buttons more, 3 buttons total, mounted sideways would be enough. You could use them for play/pause and loudness controll while the phone remains in your pocket (display locked, ...), reading mails, rss, ebooks,... without wasting display space and so on.

With 5 buttons in total you could possibly emulate a keyboard (2^5 = 32 combinations) for those who know how to play a flute. Useable onehanded, not wasting display space and faster than t9. (It's not faster than T9 - I've used this system with the microwriter agenda --Speedevil 00:00, 2 July 2007 (CEST)) Hopefully this is not patented already.

[edit] D-Pad and Buttons

  • Adding a D-pad (to the bottom of the phone) and 2 to 4 buttons (to the top) would provide some tactile input controls, in addition to the touchscreen. They could be used as shortcut keys in the menu, or playback control when playing media. When the phone is held sideways, they can be used as games controls. (With touchscreen alone, gameplay options are limited)

Game buttons would be best on both sides of the screen. The larger the buttons, the better. 2x 4 buttons in up-down-left-right configuration + some extra buttons separately a bit lower on the device would be good for many for emulation games.

Here is a concept drawing of a possible neo1973 gaming version: (This has a 4-way direction pad, 8 way may be better for gaming)
Neogame90.jpg
Shoulder buttons would be a great addition, too. It would be interesting if there was a total 4 of them, one for every corner. It would make the phone very flexible for rotating and 2 to 6 players playing on one device.

Note : The Tapwave Zodiac Palm PDA / Game console hybrid had a similar setup - with an analog stick on the left (also used for quick selection using a radial main menu when working as a PDA), 4 buttons on the right (also configurable for shortcuts when using the device as PDA), and 2 shoulder buttons. Also it had and still has an enthusiastic scene of homebrew development (almost any console emulator for PalmOS can also take advantage of the additional buttons and graphic power of the device). If we also take into account the success encountered by the GP32 in the past and the GP2X currently on the homebrew scene, it's not unreasonable to plan a future Openmoko device with both a SmartPhone/PDA functionnality and hand-held console targeting homebrew development.

[edit] Touch bigger than display

If the sensing area of the touch covered the whole front of the phone, buttons could be emulated. Palm used this to have an input area next to the screen.

[edit] Thumb keyboard or keyboard attachment accessory

  • Could be slide out or clamshell (hinge on long side) design with an external OLED. The keyboard should be protected when not in use.
  • Could be a clip on keyboard that attaches to the serial port or communicates by bluetooth (not preferred for permanent keyboard users).
  • Cheap clippable miniusb keyboard
  • One of the layouts proposed in Hardware:Keyboards
  • What about virtual keyboard? [Keyboard]

[edit] Analogue Controllers

[edit] Trackball

A trackball would provide an efficient mouse-like interface in a very compact package. As exemplified in the newer Blackberry® models. Maybe instead an optical sensor as are used in mice could be used so that the whole phone can be moved over a surface just like a mouse. (It could function as a Bluetooth mouse for other devices like laptop computers: see Bluetooth_Support#Acting_as_HID_device. Adding one other two-axis analogue input (possibly just the screen) would make the Neo usable as a TrackPoint or scroll-and-tilt mouse.) The same sensor might be usable as a barcode reader.

[edit] Analog Joystick

A joystick, or Rollermouse-like device would provide additional control, compared with touchscreen only.

[edit] Dual analogues

Dual analogue controllers (one trackball or joystick above, one below the screen, most likely) might even be feasible. That might be overkill since the accelerometers or touchscreen can be used to provide a second analogue input. But it would be nice to have four axes of analogue control without having to tilt the screen away from you or partly cover it with your hand.

[edit] TV/radio receiver

Digital Television, Digital Radio or even normal analogue TV/radio is widely available in the world, though unfortunately in various different forms. In markets where one standard is widespread, and hardware is suitable, it would be a great extension of the phone to a general entertainment device for when you're away from home. Multi standard devices would be ideal, but may not be small, low-power, or cheap. A good start would be an FM tuner, since it's one of the most widely used formats of radio broadcasting in the world.

Here's a selection of chips, though it's not clear if the drivers are open source. http://www.sigmatel.com/products/portable/wireless/fmtuner.aspx#fragment-14 http://www.st.com/stonline/products/families/automotive/am_fm_tuners.htm

[edit] Accelerometer

Avaliable in GTA02

This enables the phone to sense which direction 'down' is, and to sense any movements the phone makes.

See Accelerometer Fundamentals for more information on accelerometers as they may be used in phones.

In some cases integrated gyroscopes may also be needed. A #Digital compass can even be of more use since it gives absolute rotation so slow rotations could also be measured. A 3D compass would be nicest, but a simple 2D compass already is a helpful addition to the accelerometers.

  • 3D Viewport
  • Computer Mouse
  • Determine Position
  • Dynamic Screen Orientation
  • Change media player playlist when jogging vs walking.
  • Attempt to use to stabilise any future camera. While possible in theory the time required to process the accelerometer signals would cause to much latency, as that it could effectively be used for image stabilisation. You'd have to connect the acceleromters directly to the camera circuits.

[edit] Side-Mounted Touch Strip

Add a "touch strip" sensor onto the side of the phone which can be used to scroll. By having it on the side you can use your thumb to scroll comfortably while holding the phone one-handed. An 8-element capacitive sensor would work wonderfully and be easy to fab using either a Quantum QT411 (http://www.qprox.com/products/qslide_qt411.php) or Analog Devices AD7143 (http://www.analog.com/en/prod/0,2877,AD7143,00.html) controller. The Analog Devices chip seems better suited due to it's smaller allowable element size.

  • With the AD7143 you can have an 8-element (128-position) 25mm long strip - Perfect!.
  • With a few OLED screens beneath the strip it could be used as dynamic configurable buttons/alerts eg. zoom/flash/shutter with a camera application and SMS/Email/Voicemail alerts in standby

[edit] Heart Rate Compatibility

An RF interface to receive data from popular heart rate straps (Polar, Garmin, Sigma, Suunto, etc.). This would go along well with the existing GPS functionality and possible future Accelerometer functionality to make for a full-blown workout tool.

Software can be written to track heart rate along a running, cycling, skiing, swimming loop, to monitor max and min heart rate, to match heart rate data to GPS coordinates and print map data w/ relevant data.


Consider using the heart rate monitor from Zephyr tech. This communicates over bluetooth and has an SDK available. http://www.zephyrtech.co.nz/products/consumer/hrm

[edit] Digital compass

A digital compass is useful for orienting maps to the terrain and other location/direction/orientation based applications (... is 300 meter that way) when the user is standing still (regardless of GPS reception) and for following a bearing when GPS reception is poor or speed is low. Also could be used to make the accelerometer data more exact.

A compass is also useful for tagging photographs with the correct direction (in addition to location) of the photo.

Very small I2C sensors like Honeywell's HMC6352 2-Axis Digital Integrated Compass (6.5 x 6.5 x 1.5 mm) are very appropriate for this. Another option is the much smaller Yamaha YAS529 Three-Axis Geomagnetic Sensor IC Chip (2.0mm x 2.0mm x 1.0mm).

See Wishlist - Hardware: Digital compass for more information

See I2C Compass for an attempt at one

[edit] Thermometer

An electronic thermometer might become handy for some users.

There are very small I2C devices available, that could easily integrate to the existing bus. For example this one from ti. (Could just be cheap and use the thermometer from the battery, thats how they did it in the nokia 5140's). Also is integrated in a barometer/altimeter like the SMD500 mentioned in Wish List - Hardware - Atmospheric.

But if you carry it in your pocket it is unlikely to show the correct air temperature anyway. AudriusA 17:12, 12 January 2008 (CET)

[edit] Barometer and Variometer (Altimeter)

A Barometer measures air pressure. This can be used to give weather information, and also as a variometer, to sense relative altitude. Variometers are commonly used in flying microlight and ultralight aircraft, to get accurate relative altitude.

These are also common on high end GPS units. This is a great feature for walkers as you can tell how far you have got on any ascent/decent.

See Wish List - Hardware - Atmospheric for more information.

The GPS device outputs the altitude as well. This has been tested and works fine. AudriusA 21:44, 7 February 2008 (CET)
The precision of GPS altitude is very coarse in comparison with a pressure based altimeter, in the order of 10m for GPS vs 25cm for a altimeter PTT 10:39, 13 October 2008 (UTC)

[edit] Finger print sensor

A fingerprint sensor gives easy and fast access to the phone, could lock the touchscreen etc. An example of this device can be found at Sony UX17.

Most fingerprint sensors in the embedded market include a navigation mode, where they work similar to either a touch-stick or touch-pad of a laptop.

Fujitsu has a small strip like reader that has SPI and USB support.

[edit] Barcode Scanner

  • less cpu intensive and more reliable than camera+ocr
  • though, bluetooth-enabled readers are already available.

[edit] Light Sensor

Ability to sense ambient light, and act accordingly. i.e if it's 3am and LightValue<.1 then Ring Quietly.

It can be used to tune brightness of LCD automatically.

Can camera be used like light sensor? (when we have camera)

[edit] A pluggable sensor module

Give the option of a composite sensor module consisting of pressure, humidity, temperature and light sensors(if camera not present, which is the case), which will be pluggable to the phone and connected to the USB 1.1 port.

[edit] Wheel

A navigation wheel like on a sony/ericsson 810i would be nice.

The wheel could be mounted beside the headphone jack. In software, it would be appropriate for it to appear as a mouse wheel to applications. The wheel should also accept a press which emulates a middle mouse button click.

Uses for this include: 1. Scrolling lists, with middle button as click/open item. 2. Volume control while talking and in media player. 3. Scrolling pages

[edit] Proximity Sensor

Switch off backlight when you place the phone to your ear. Prevent accidental activation of speakerphone or other sounds when the phone is near the ear (prevent hearing damage). Possibly switch the speakerphone on or off automatically depending on if the phone is by your head or not.

Automatically turning the speakerphone on/off sounds good, but to avoid disturbing others, for example in public, turning it on could be delayed so for example short looking at the display or putting it to the other ear doesn’t activate it. Additionally/alternatively the delay could be combined with/replaced by a orientation (or motion) sensor, so that it’s not activated when holding it upright, but only when it’s lying e. g. on a table.

[edit] Make all unlocking of phone, password protected

When my (current non-neophone) phone is in my pocket and I have it locked, it sometimes accidentally unlocks itself since only two keystrokes in the correct order are necessary to unlock it. When it's unlocked and still in my pocket it sometimes calls someone without my knowledge. All phones I've seen today have a press-just-one-button bypass to answer an incoming call even when the phone is locked. I suggest making the locking mechanism let the user configure it so that the user has to enter a password even for answering incoming calls. The likeliness of the phone accidentally runbbing against my car keys, hitting a ten character long password, unlocking the phone without my knowledge and consent is low enough even for us most unlucky users.

[edit] Expansion

[edit] Positioning of Buttons, Connections and ports

Ideally any cable ports such as charging, USB, audio, docking should not get in the way of your hand or fingers when holding it in it's normal orientation. For the sake of SDIO cards an external SD slot should be on the top edge. IR for remote control software and ease of inter-device communication should be on the corner so that it is facing away from you for both orientations. Buttons obviously are positioned for finger control. An example of how not to do this would be the HTC Universal

[edit] Storage

[edit] MMC/SD/SDIO slot (rather than?) miniSD or microSD

  • Cheaper, more durable cards in a widely accepted format.
  • Much much larger storage capacity, even 32GB
  • Cards are harder to lose
  • Wider selection of accessories, including SDIO accessories.
  • Make externally available so that larger length SDIO cards can be used (thinking about SDIO WLAN here)
  • SDHC compatible. It seems to already have the right hardware for it - see Neo1973_Hardware#microSD-Card.

See more on Wish list - SD Card Slot

[edit] Two SD slots

  • Micro SDHC for /home partition. Keep like current design underneath SIM card
  • Hot swappable externally accessible normal size SDHC/SDIO slot

[edit] Internal Communication Bus

  • A standard and/or documented internal communication bus of some sort could simplify adding new hardware modules.
  • Serial USB or I2C connector internal to case towards the top
  • Several digital I/O pins that operate at TTL levels
  • A few analogue I/O pins attached to a A/D converter
  • Documentation of Debug board connector could provide some of this functionality.

I2C is used on the Neo with some details of resources already in use documented! Please see Neo I2C Devices for more information & a list of devices & the addresses currently in use & documented for the Neo1973.

[edit] Local Communication

[edit] USB

  • 5V Powered, to avoid having to carry around a hub for when you want to occasionally plug in a memory stick. Many powered hubs will not recognize a totally unpowered host. Provide a maximum current to drive a basic USB keyboard/memory stick/mouse/webcam/astrowebcam. This could be done by adding a small cheap power converter like the LM2753
  • USB 2.0 (USB 1.1 is too slow to transfer data to the card, removing the card everytime from the phone isn't an option too, because it is placed under the battery)
  • Standard type A socket for quick & easy insertion of memory sticks and all kind of devices. This type of connector is more robust to wear and tear compared to the type B socket which is more prone to break down.
  • OTG, to be able connect usb keyboard like Cherry G84-4321 SUNRG
  • Bootable USB device emulation: the possibility to boot any computer on a bootable flagged partition of the transflash.
  • Protection against incorrectly wired USB ports: some USB ports are wired incorrectly; if the +5V and GND are swapped, the device would get -5V when it's expecting +5V, which could burn some chips. A reverse-biased diode between +5V and GND, D+ and GND, D- and GND, and (if used) ID and GND, with a low enough forward voltage drop (to limite the negative voltages to what the chips can withstand), would protect the device by tripping the port's short circuit protection.
  • 2 USB-Ports; one for acting as USB-host and one for acting as USB-device at same time.

[edit] Wireless USB support

Wireless USB is the wireless version of USB offering data-rates up to 480 Mbit/s over short distances (<3 meter). Chipsets suitable for a phone are likely to take some time to be available.

[edit] Bluetooth with A2DP

Is the blue-tooth radio present in the phone A2DP compatible. If not, make it so.

Great for listening to music or watching a movie with full sound.

[edit] SIR/FIR transceiver (Serial Infrared) / IR remote control

  • An infrared transceiver is cheap, small, and useful for sync with many laptops and mobile phones.
  • Replace/emulate all IR-based remote controls used for your tv, vcr, etc on your neo cell phone.
    • replaces multiple 'dumb' devices with a single intelligent device (your neo) that you will probably carry with you at all times anyway.
    • Command sets should be retrieved from a database or learned from other less intelligent remote control devices with macros.
    • reduces clutter, particularly in the living room.
    • inceases the neo's practical status as an 'always-have' device.

Other uses.

  • Detecting reflections from inside of a caddy, and switching from active mode.
  • FIR would be a nice option, as it's some 40 times faster than SIR.

[edit] Other

[edit] Video Out

  • Through a docking port
    • S-Video/Composite Out
    • DVI Out
    • HDMI Out
    • Display Port

[edit] Output devices

[edit] LED

  • The Neo1973 GTA02 will have LEDs of some sort behind at least one button. [1]
  • A blinking LED would be a cheap, low power way to inform the user of new SMS/Email....
    • An alternative to this would be for one small part of the LCD to be separately backlit.
    • This requires the CPU and LCD to be somewhat active, to keep the LCD refreshed, but gives much more information.
    • A Small OLED Screen could be used and display much more information than a LED with minimal power usage.
  • For example a multicolor LED which pulses yellow for GSM/GPRS transmit, blue for Bluetooth/Wifi, green to indicate non-urgent information - missed call etc, red to indicate battery low or other urgent notices.
    • The LED and button ideas could be combined: illuminated buttons.
    • It must be possible to completely disable the LED to save power or other personal preferences.

[edit] Flashlight

For finding keys, or any other application. May also optionally pulse in time with ring, to make phone more visible. This is really well done in Nokia 5500.

-I second this one. The most used feature in my Nokia 5140 after the calling and sms features is the flashlight. It's just one simple LED, but powerful enough to see with if it's really dark. If it ain't dark, you won't need the light anyway. :)

Also, Who hasn't lost their keys and opened up their cell phone to use as a flashlight?

[edit] FM transmitter

Small FM transmitter to output to car, and other nearby radios.

Fix the biggest flaw in the iPod before Apple does!

[edit] Infrared Transmitter w/ universal remote software

Infrared LED on top of device with universal remote software so you can control televisions, DVDs etc. Here is an example of universal remote software.

I'd like to add that i fully support this. An IR port on future openmoko devices capable of controlling set-top boxes like TV/DVD/Stereo is necessary to make the device as universal as possible. A cellphone should be your window to the world and allow you to interact with it in as many ways as possible.
Care must be taken to use the correct type of IR chipset/controller in the phone. Most IR ports you find on devices like computers, some cellphones etc. Are for high speed data communication and CAN'T control TVs/DVDplayers/Stereos etc.
In order to reduce cost it maybe possible to use the sound chipset in the phone to generate the waveform sent to the IR led. IR remotes work at ~38Khz which is within the range of the sound chipset. The sound output could be internally switched between the IR led or the speakers.

[edit] HAC Compliance

Here is some summary/discussion of how hearing aid compliance rules work in the US. Specifically it would be nice to see the phone include a telecoil, which allows the phone to connect wirelessly to many standard hearing aids.

[edit] Mobile Communication options

[edit] Generic Access Network / Unlicensed Mobile Access

This technology requires cooperation from the cellular provider, but UMA/GAN is already offered by T-Mobile in the United States, and perhaps others in other countries. Allowing the user to roam from GSM to wifi, this technology can save the end user a significant amount of money, and also allow the user to deploy coverage where there was none before. There are only a few UMA capable phones currently, but it would be great if this could be made to work on a phase 2 type Openmoko device.

Note that this features requires more advanced access to the GSM modem. Special messages needs to be exchanged with the network.

[edit] Faster/better mobile connectivity.

GSM/GPRS is at best slow. An incremental improvement would be a radio with EDGE support. EDGE is an evolved GSM standard and, like GPRS, it operates on the same frequency as voice. This means a quad-band EDGE radio will have near-complete worldwide coverage.

UMTS - which is widespread in Europe and being deployed in the US, HSDPA (asia) and any other mobile standards would be nice for faster data connectivity and coverage. It is unlikely that all of these will be supported initially, but it is a goal. These faster standards operate in different frequencies from GSM/GPRS/EDGE. Which frequency exactly will depend on the carrier and country. For UMTS in the US, AT&T uses 850/1900 MHz but T-Mobile will use 2100/1700 MHz for example.

Until that goal is reached, it is likely that some phones will be brought out for various specific markets - Europe, Asia, US.

[edit] Ability to use multiple SIMs/networks

  • External SIM sockets are widely available in China, a dual external socket would be a very good solution.
  • Dual SIM card kit - two SIMs are trimmed and combined, software supportwould be needed, and both can't be used at once...
  • Some networks support multiple numbers on one SIM. Unfortunately this won't allow split networks.
  • A second/dual GSM module would allow full use of both sims at all times.
  • As a hack, use another mobile via BT.
    • As many as three SIM slots would be genuinely useful, especially for a 3G phone - some 3G data tariffs are only available on data-only SIMs. A user could quite reasonably have one SIM for data, once SIM for his personal voice calls, and a third SIM for his business number.
  • Dual SIM card support will be especially welcome by the women. They just love to talk on the phone.
  • Save the contents from several SIM-cards to memory and simulate them.

[edit] PMR446/FRS Radio

  • Include a PMR/FRS Radio.
  • A two-way walkie talkie lets you use the phone to communicate with friends without requiring a GSM connection (crowded networks at festivals, at locations with no GSM coverage).

2 way talk over Sprint/Nextel/Boost networks if possible. At least the walkie talkie feature for sure. It's very annoying being at a lake with no service and can't call your friend in the other boat across the lake.

[edit] DECT

  • Include a DECT GAP/CAT-iq transceiver so you can use your home and/or office PSTN line
    • Ability to use Alcatel phonebook stuff (like provided by the eventphone.de phone equipment) would be very nice too

[edit] SIP phone

Make stripped down (and thus cheaper) version of the Neo1973 phone for use as a SIP phone. Remove GPS, GSM, accelerometers, stylus.

Addition of an centimeters-precise location system RTLS would be nice, as it will allow highly sensible indoor context detection. Imagine putting the phone next to your mirror (where you shave daily) and watch it automatically switch to news radio channel. Or put it next to your bed and see it automatically switch to "sleeping" mode, when only calls from predefined numbers are accepted.

[edit] Casing

See also: Alternate Neo1973 case designs for a list of cases being considered for design/manufacture by the community.

[edit] Generic Back Plate Connector

If the Neo had a few connectors below the back plate, it would be much easier to develop custom backplates. Connectors needed would be GND, Power-out, Power-in (for charging/expansion battery appliances), some bus (either USB or some other bus, maybe usb wouldn't be the best choice since having a backplate and an upstream connection at the same time might cause problems) and maybe some ID pins to discern battery/charger/generic expansion modules on hardware level --DrDeath 10:39, 27 September 2008 (UTC)

[edit] Expansion Module Casing

Longer case (150-160mm+) with space in the top to put expansion modules, including test & hobby hardware. Would require use of a standard internal power & communications bus. Could be left empty with blank cover or house cameras, solar panels, a crank powered charger, special transmitters/recievers, or anything else imaginable.

Neo1973 Expansion Module Quicktime rendering
Neo1973-Exp.png



-mb make a bigger higher resolution screen and the hardware will still be the same size and the free runer bigger a in the free place make z sliding thing wich you would sell in many colour and if sb whants a camera hi can buy it in the sliding thing or he can just buy it blank for his own hard-ware this would be cool this sliding pice could have some cind of shape thet would fit and let you the most posibilities even you could make it covering some front of the phone so you could place a joystick and buttos in it. If you would need leds you would buy a blank cover drill it and it would be fine becous you wouldnt injury the mine case of the phone.

[edit] Expansion Back Casing

Replacement backs with additional features ranging from solar power, larger batteries, extra hardware, ...

[edit] Expansion Front Casing

Replacement fronts with e.g. extra buttons.

[edit] Clamshell Casing

The clamshell form factor is much preferred by many in that: 1) it provides more area for both screen and keypad 2) its easier for one handed use, the buttons arent crammed in the bottom of the casing 3) clamshell open up to provide longer distance to cover both ear and mouth so you dont have to shout in noisy areas to be heard because the speaker is up on the side of your face 4) clamshells protect the screen from scratches

[edit] Space efficient Lanyard

The hole at the bottom of the phone takes a lot of space. A Kensington Security Slot could be used instead.

[edit] Rugged version

We need something you can drop from 4 feet in to a puddle of dirty water on construction site. Sunlight readable display, maybe aluminium case. The big ugly pseudo military version. What about a casing similar to the OLPC project's in terms of dust and waterproofing? I frequently have to answer the phone with hands dripping sea water and most phone's do not take kindly to that type of treatment. Also the accelerometers can be wired to a protection mechanism which suspends all processing/data activity in case of a (free) fall.

  • Seconded. Would get one at once. please IP68 and with rubber coating.
  • I support this too. Might make more sense as an accessory which you can snap/peel onto your phone however?
  • I'm eager to see a ruggedized version, maybe even floatable.
  • +1. No point in having an excellent phone/PDA-device, if you can't take it with you where ever you may go. I think this might work as an optional accessory case design, as a previous contributor mentioned.

[edit] Transparent

Make a transparent, see-through casing. Why do we need a closed casing for open hardware and open software? Show the world it is a truly Free/Open source phone.

That makes sense to me. I second that idea! Me, too! +1 :) i would buy one!

[edit] Blank

Even though the transparent case would work too, I would like to see a blank case of pure black or white so people could have the option of air-brushing,painting or even drawing on the case.

[edit] Integrated solar charger

Perhaps on one side there could be an integrated photovoltaic. It would be small, but might it be enough to charge the device. It could be integrated in an aesthetically pleasing fashion like this... except, with a matching color. :)

[edit] Custom look

Provide a service which offers custom case design like this one, see images below. Just upload two images, reposition them in an interactive website, submit credit card information and the custom case design with application manual will be shipped to you.

[edit] Misc

[edit] Battery Size/Standby Time

Since the device will be ultimately running a wide selection of software on it the battery needs to be somewhat more robust and have a longer standby time than that of current phone's. At the moment I'm using a Moto (2 days before charging) or a Samsung (3 days before charging) and am not impressed with either phone's standby time, and I'm not using the phone's for anything but calls.

[edit] Dedicated Power / Charger Pinout

Having not yet seen a physical Neo device, I haven't been able to examine any of the IOs to see if there already is a dedicated power / charger input. However, I can imagine that it might be very tempting to have the device charge solely via USB. For any device that is capable of USB-host, that is a horrible idea, particularly when it's intended to be a mobile-komputing device.

Since the device is able to run in USB host mode, it might be a good idea to allow for an alternate power supply, if say, a USB keyboard was being used for several hours. Rather than drain the battery, one could just supply power via the wall outlet while still providing endless hours of USB-host enjoyment for those hard-coders on the go.

The main question is just deciding on where to take power from (or at all) if in USB-client mode and the power cable is inserted, but really, that's not too big of a deal and can be solved with very minimal circuitry. If 5V is detected on the power line, then the obvious place to get it from is there at any point in time.

This might sound extraneous at first, but when the device shuts down in the middle of an important USB file transfer, or right before that great piece of code was saved, you can bet that those users will be saying "Hmm... a separate power adapter would have really come in handy right now".

I suggest a tiny 3mm, dedicated +5V power input (something a la Nokia).

With the dedicated charger it would also be possible to use any standard USB device if the phone recognized the external power and enabled 5v power when plugged in.

[edit] Galileo/GLONASS/GPS receiver

  • A multi-standard satellite positioning module would be nice eventually, it does not seem to be near-term due to chipset availability problems. Galileo is the to be launched (2011) European positioning system. GLONASS is the already existing Russian one.

[edit] GPS antena

The current GPS device seems even dependent on weather and may not work in heavy rain or snow. It seems necessary to think how to improve the reliability. The small portable GPS antena may be an option.

[edit] X10 RF Remote

Many PC-based media centers are being equipped with an RF (433 MHz) / X10-based remote control. The X10 protocol also facilitates home automation to control lamps, switches, etc. The advantages of using RF for control instead of Infra-red this that it also works when furniture, walls, or doors are blocking the path between RF remote and the equipment or device. Lirc supports X10-based RF remotes (but expects having an USB RF receiver attached to the media center).

[edit] RFID tag/RFID Reader

  • Implementation/Cooperation with: RFID-Guardian
  • An enable-able tag would be of use - for example being able to use the phone to open doors, or cars. Unfortunately, it's moderately hard to do secure programmable tags that are compatible with existing systems, for obvious reasons.
  • Say you have RFID tags on your personal belongings: cellphone, keys... Neo could be programmed to remember the last recorded GPS location before it lost contact with the respective RFIDs. It'd be trivial to check where you left your cellphone, get directions from a map...or beep when the phone gets out of RFID range.
  • I agree with this idea, a great idea and you have to do it (Jackcday)
  • Or, a python script that use the accelerometers and rfid reader, so when the phone moves it checks for an rfid tag (that would be in the users pocket) and if it doesn't get a response it rings in full volume, or starts a tracking utility :))))
  • A RFID reader would need an antenna loop which could probably be used for wireless docking or even charging
  • connected RFID UHF Reader to the openmoko via USB Host Mode http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=5612279
  • some hardware project is there: Freerunner_RFID_Board

[edit] NFC chip

  • A Near Field Communication chip, with this chip it will be possible to pay with your phone (like a credit card)in the near future, see Nokiafor details
  • NXP is a chip fabricator which provides NFC chips NXP direct link>> www.nxp.com/#/pip/cb=[type=product,path=/53420/53424]|pip=[pfp=53424][0] their chips also support the above RFID reading
  • a technical note: NFC is an extension of RFID where two readers can communicate with each other i.e. both are quite similar

[edit] Less weight

  • Work on the weight of the Neo1973 and following devices. At the present time the Neo1973 is just a moderate / normal business or multimedia phone. The ordinary "user" may want something lighter. Take a look at the following table, that's the Neo1973 compared with other common business or multimedia phones.
Neo1973 Fujitsu-Siemens LOOX N560 E-Ten Glofiish X500+ Sony Ericsson P990i iPhone Nokia E65
184 g 160 g 146 g 150 g 135 g 115 g

[edit] Make it smaller

  • To stay within physical matters: Maybe the Neo1973 is also just a normal business/multimedia phone when looking at the size. It would be great the shrink it a bit. Especially the thickness of 18.5 mm could be worked on!

[edit] Standard 3.5mm headphone jack

The Neo1973 uses a 4-conductor 2.5mm jack for stereo headphones and a microphone. A 2.5mm jack is the most common for headsets.

There is an emerging convention used in the Nokia N800 and some other devices. A 4-conductor 3.5mm jack that can use a microphone with special headsets, but can also be used with off-the-shelf 3.5mm stereo headphones. Adapters to 2.5mm are of course available and this 3.5mm jack is much more robust.

Neglecting space limitations, multiple sockets - 2.5mm and 3.5mm would be nice. Probably not practical in a phone. Other expanded plugs might allow remote controls.

Other uses might be better met using bluetooth, or USB audio.

[edit] Software should know of the jack status

It should be possible for the OS to see if there is something connected to the audio jacks. That would avoid the embarrasing moments when you accidently pull out the headphones from the cell/laptop and whatever you were listening blares over the place at full volume. If OS can see, that the headphones were unplugged without turning off the audio, then it could pop up a warning that would allow to direct audio to internal speakers or turn it off. If the user would replug the headphones/speakers then the warning would dissapear as well.

[edit] Laser Pointer

Include a built in laser pointer. Everything is better with lasers.

Make it a green one <10mW so it won't be illegal in quite a few countries.

[edit] Completely free hardware

Consider selling one device with absolutely no non-free components in it, even if that means dropping the GSM support. I believe having one such device available would be good, because then it could be recommended by organizations like the FSF which typically never recommends anything if it has even a little non-free code in it.

[edit] Consider economy / inexpensive / less featured edition

Some people want less features, because they do not need them. Leaving out some features either lets the phone get smaller or possibly enhances battery live.

One big suggestion in this area is a b/w lower res display instead of the big color display.

[edit] Inductive Charger

It would be nice if it was possible to charge the phone without having to connect a cable. I'd like to have a simple docking station with an inductive charger like the type that's used for electric toothbrushes [2]. The charger itself could get its power from a standard wall-wart power supply, or it could be USB/Firewire powered.

[edit] Examples of existing commercial systems

  • might be combinable with a RFID reader

[edit] Solar panel/dynamo Charger

It would be very nice to be able to charge the phone outside of the electric grid (for example on hikes and boating trips). A combined solar panel and muscle empowered (rotational etc.) charger would do the trick nicely.

  • It might be possible to include a charger based on a step motor and an excentric weight, similar to automatic wrist watches. Charge by walking/running, if that wouldn't be cool...

- I think a dynamo charger ("share charger", rotational, ...) would be more practical as a peripheral, connected through the USB-interface using the same principle cellphones now charge when connected to an USB-port. You could very easily hack this together. flashlight recharge hack

Random thought; Why not create some merchandise toys with a small lithium battery which charge through centrifugal force allowing to recharge the phone with a small "general" connector.

[edit] Plastic Solar/Back side on the Neo

Solar cells from Plastic, on the reverse side of the Neo 1973 modified and introgreated in the battery backcover/flap, like an energy source when the display is in standby mode. Thats can be use also as alternate charge method's and also helps in emergency.

[edit] Vibration

Instead of using a counter-weighted motor to provide a vibrate function, a small solenoid could be used.It would provide more of a tap or click feel. It could be used to provide feedback when a on screen button is pressed. Different patterns of taps is a lot easier to recognize compared to different vibration frequencies. For those who know morse code they could have the phone tap out the phone number/name of the person calling/messaging or other alerts.

[edit] As plug-in without screen...

Along the lines of add-on cards, only looking at it from a different angle, I'd like to see a "faceless" openmoko with a documented hardware interface for both communicating with it and inserting it into other devices. Even the keypad/screen/battery would be attached, openmoko itself would just be faceless sliver of hardware with a documented interface and an API for communicating with the innards.

[edit] Running without battery

Please make it possible to run the device without a battery inserted (with the charger attached). I have several mobile phones which do not work anymore (even when attached to the charger) because the battery is worn out and new batteries are not available. I want the Openmoko to be usable when the battery is worn out.

  • Seconded.

[edit] Make GSM/CDMA/WiFi/WiMax/GPS plugable

Please make Openmoko mobile as PC GSM/CDMA/... just working like plugable cards, they are cards/adaptor for the DEVICE only. the user may eject GSM module and inject with CDMA module. the DEVICE may provide several slot to allow user choose wifi/wimax/sd/gps/harddisk/...

[edit] Wifi chip that can be used with kismet and other sniffers

Please change the wifi chip that also can be used for sniffing wifi connection preferably the latest standard, not N. For pen testing. A wifi chips like the RT2800 I think?

[edit] Add a connector for an external Wifi aerial

PLease can a an external aerial connector be added so better arials can be used useful for sniffing wifi connections for pen testing etc.

Hardware enhancements

Some small hardware enhancement could be cheap, but very useful. Please add your ideas/wishes here:

Video-capable camera
  • preferably in rotatable turret set into top of unit, so it can face in either direction, making it useful for video conferencing. For a phone to stand a chance in the modern market it will need a camera else it is likely that it won't be bought.
Integrated WiFi hardware
  • To sync data
  • To access Internet when WiFi is available (at home, work, school, friends)
  • For VoIP (this uses much power but maybe the user have the charger connected)
    • I'm willing to port Yate to it if the Internet connectivity issue is solved --@Dexter 13:58, 16 February 2007 (CET)
  • for videoconferencing (as with AccessGrid)
  • Even 802.11b 11Mbps -only would do -- the point is being able to connect it to the Internet without incurring the (sometimes huge) costs of GPRS or (even worse) HSCSD.
  • To save power have WiFi able to wake up and check for a designated SSID then sleep again if not found (i.e. I'm not home) or wake up by GPS location (only come up at home and in the office)
  • Variable TX power, to the minimum needed to connect to the AP.
  • Some sort of caching (encrypted?) internet proxy that can store and forward packets. Instead of having the radio constantly on, it turns the radio on every 30s, for just long enough to register with the AP, and ask the proxy if it has new packets for it.
    • An optimisation might be if the hardware, and the AP can do broadcast packets. The receiver is only turned on for .5s/30s, to recieve a broadcast packet saying 'you've got packets' without registering with the AP, or transmitting at all. The GPS synchronises the timing.
    • This slows the initial connection to the phone, but most tcp/ip applications will not time out in 30s.
LED
  • A blinking LED would be cheap and low power, good for informing the user about new SMS/Email....
    • An alternative to this would be for one segment of the LCD to be seperately backlit. There are many LEDs in the backlight, all normally on. This has the advantage that you can display reasonable amounts of information on the bit of the screen that's illuminated.
    • The disadvantage is the field of view is smaller, and it's dimmer than a bare LCD, as the LCD absorbs some light.
    • This also requires the CPU and LCD to be somewhat active, to keep it refreshed.
  • Note: the LED and button ideas could be combined: illuminated buttons
  • A yellow LED for GSM/GPRS Tx burst, a blue one for Bluetooth/WiFi Tx burst, a green one for non-urgent notifications (sleep state, missed call etc.) and a red one for urgent notifications (battery almost drained out, new SMS etc.). All of this could be done in one, multicoloured (RGB) LED, similar to the nice one on the Yaesu VX-7R.
D-Pad and Buttons
  • Adding a D-pad (to the bottom of the phone) and 2 to 4 buttons (to the top) would provide some tactile input controls, in addition to the touchscreen. They could be used as shortcut keys in the menu, or playback control when playing media. When the phone is held sideways, they can be used as games controls. (With touchscreen alone, gameplay options are limited)
Accelerometer

This enables the phone to sense where 'down' is - to enable various options.

Change playlists when I'm jogging vs walking. (there ia an mp3 player on the market that does this).

  • Can't the GPS information be used for that purpose? It should be possible to derive the phone's velocity from the change in coordinates over time, so such a playlist profile switcher should be a possibility even now already. Abraxa 00:09, 18 February 2007 (CET)
    • Yeah in my opinion that is a very cool idea. But for that case the device should be much lighter. I wouldn't go jogging with a device with this size.--denis_std 01:01, 18 February 2007 (CET)
SIR transceiver
  • Could be used to detect when to turn off the display (if the low power IR signal is reflected) and activate the key lock. And could be used as a remote. iPhone has a proximity sensor.
  • FIR would be nice as well, but I would settle for SIR if it would be added. Linux already has a working IrDA stack so the standard part would be satisfied. I would be more than glad to write lirc thingies for OpenMoko then :)
Standard 3.5mm jack
  • I think everyone interested (and knowledgeable) enough to buy a Neo can make a 2.5mm male to 3.5mm female adaptor cable in under 1/2h and under 10EUR :-)

Certainly - now make it light, small, pretty, durable, tangle-free. I want a 3.5mm jack. The only problem is - are headsets widely available in the same format as 2.5mm. --Speedevil 14:28, 16 February 2007 (CET)

Multitouch screen
Multi I/O adapter
  • VGA, standard Jack (line in & out), standard USB
MMC/SD/SDIO slot (rather than?) miniSD or microSD
  • Cheaper, more durable cards in a widely accepted format.
  • Cards are harder to lose
  • Wider selection of accesories, including SDIO accessories.
  • Make externally available so that larger length SDIO cards can be used (thinking about SDIO WLAN here)
  • Only because CF takes too much room (or CF would be the wish, instead)
Expansion Back
  • Replacement backs with additional features
  • I believe this would be a great idea, if put into practice. It would solve the extensibility need, usually associated with Open Source projects. It would allow for lots of other devices and for functionality to be developed and put into use without making it a burden for FIC.
    • With extra card slots and small footprint hard drive (if possible), Neo might become a nice image tank for photographers - --cedel 18:34, 19 February 2007 (CET)
Thumb keyboard or keyboard attachment accessory
  • Could be slide out or clamshell (hinge on long side) design with an external OLED. The keyboard should be protected when not in use.
  • Could be a clip on keyboard that attaches to the serial port or communicates by bluetooth (not preferred for permanent keyboard users).
  • cheap clippable miniusb keyboard
LASER keyboard (can be a full QWERTY keyboard)
  • On the hardware side, this would require a $5 laser diode, a $3 (in bulk) custom diffraction grating, and probably a couple of cubic centimetres volume inside the phone.
  • This requires a camera pointable to the front.
  • It requires an integrated stand for the phone.
  • To practically use this, you've got to be 40cm or so away from the phone, which means under 25*20 of text resolution.
  • In software, it's relatively easy to parse the camera output, to find changes in the known laser field.

There are major problems.

  • Patent issues.
  • No tactile response at all, which slows typing.
  • An extra 2cc/6g.
EDGE support
Ability to insert more than one Sim-Card and (if possible) connect to more than one network at the same time
  • This could be achieved via a specialist dual sim card kit (currently on market)- where two sims are trimmed and combined on one card, software support for dual sims would need providing...
  • What about twin-SIMs (SIMs with 2 phone lines registered on them)? Conventional GSM phones have an option to switch between the two, older ones use # (long press before dialling) to do that. I'm guessing Calypso should support it, we just need to provide an interface for it :-) --@Dexter 11:34, 19 February 2007 (CET)
RFID tag
  • Implementation/Cooperation with: RFID-Guardian
  • Advantages of a RFID tag? I would see a lot privacy problems
    • The tag could be switched on or off. A nice feature would be a module able to clone tags. This would unfortunately probably be rather expensive.
    • What about an RFID Reader which could be used to locate items with RFID tags (IE: in your house) Alexpb
      • That would be a nice feature--denis_std 08:33, 17 February 2007 (CET)
      • Most tags can only be located within 10cm or so. Essentially no cheap tags can be located over several metres.--Speedevil 13:17, 18 February 2007 (CET)
USB 2.0
  • Powered
  • Host Mode / Device Mode
  • OTG
UMTS support
Dump the egg-shaped case design and go rectangular for more screen space
  • I'm all for devices that look great and have great features - aside from that I really like the current design. Thus I'd like to comment that the design change request is probably not the majority's opinion. Abraxa 00:00, 18 February 2007 (CET)
A standard slip-on or clip-on template (possibly with buttons) to make the touch-screen blind accessible
Speakerphone functionality
Reposition Speakers
  • putting the two speakers on opposite sides of the screen would make the stereo sound much more effective

The screen is 2.8" across. That's not especially effective. Also, the speaker noise does come out the side - look at the grills in the pictures. --Speedevil 06:19, 16 February 2007 (CET)

Small metal frame for protection (like Siemens M65, only with more style)
Free GPIO ports on a connector to allow easy, simple hardware extensions
Video acceleration

Hardware acceleration for video playback.

3D acceleration

3D hardware acceleration for 3D games, GUIs, etc. (maybe a PowerVR MBX Lite ?).

Alcohol Sensor

Alcohol sensor adjacent to microphone. It doesn't have to be accurate, just has to detect any amount of alcohol on the speaker's breath. I understand this is a very narrow market, but alcohol is on every parent's mind.


Disinfection UV-Light

I had read about it in an Article on http://www.americanairandwater.com/UV-news/. But Motorola patents it. Yes - finally a way to stop the billions of annual deaths due to cellphone infections! --Speedevil 14:04, 16 February 2007 (CET) It´s just something that flying in my head... It´s not the first "unreal" or "useless" idea. Just for fun! --MookiE 14:51, 16 February 2007 (CET)

More seriously - UV of the required frequency is inherently eye-damaging. Also, as I understand it, there are actually no UV LEDs that will reliably produce 'germicidal' UV. The most expensive - and they are very expensive - ones produce UV of a sort that may kill very susceptible bacteria, but comparatively few. IIRC the LEDs are $20 per. --Speedevil 15:11, 16 February 2007 (CET)

Teleportation

Implementing a beaming-device to the Neo would make it the first phone enabling teleportation. See: [1] Possible implementation difficulties might be the lacking teleportation-support in the GSM standard as well as uncooperative mobile service providers that feel uneasy towards innovative technologies...

EPD

Or electronic paper display, EPD is used in many new devices such as the new Motorola motofone, sonys new e-reader and Irex's iliad. The technology provides thin, flexible, power saving screens using new eink technology. This technology could cut the weight of the phone and its power usage. For more info see: eink's website.

FM/Digital Radio(DAB) Reciever

A nice feature would be a radio reciever: FM or even better: Digital Audio Broadcast (Digital Radio)

V12 Embedded power source

We'll need something beefy to power the next Neos for the above gadgets, I propose the use of a Embeddable Power Source, that with some miniturisation and a bit of design work should be workable as a possible solution.

Thermometer

An electronic thermometer might become handy for some users.

Maybe we could even integrate a DS2490 usb-to-1wire chip (about 15x10mm) in the phone along with a DS1820 1wire temperature sensor and possibility (by internal or external connector) to add further 1wire devices like humidity sensors, secure authentication, buttons, keypads etc? The Linux kernel already happens to have a ds2490 driver.. This of course would require there to be a free internal usb port to connect the ds2490 to..
