In small quantities - this will be over $50 or so, including attachment of connectors. Custom flex PCBs are expensive. However, this would allow easy integration of buttons, mic, and speaker related electronics. It may not be possible due to bus capacitance requirements. --[[User:Speedevil|Speedevil]] 00:25, 17 July 2007 (CEST) | In small quantities - this will be over $50 or so, including attachment of connectors.

| − | There are connectors avilable at gumstix for $6 for a pack of 3. I wouldn't know where to start looking for a film ribbon connector, but I'm sure it wouldn't be hugely expensive. The capacitance point is something I hadn't thought of though; we should be able to keep the length to around 30mm - I will look for info to indicate whether this is acceptable or not.

| + | There is talk on the gumstic docwiki of a jtag board connecting through the 60-pin hirose, I owuld assume this is via some sort of ribbon connector, which will be at least as long as we require to conenct to another module. | ||

intel xscale open?
i remember mickey saying on that linuxtag presentation that xscale is no option as there are a lot of NDAs and no way to get open documentation for the xscale processors...?! --Minime 15:59, 13 July 2007 (CEST)
In the gumstix case, this may be irrelevant, as they provide suitable drivers. --Speedevil 16:25, 13 July 2007 (CEST)
gsm included with gprs/gps
i've removed the line/link aobut having to buy an extra gsm module, as this is included with the samsung gprs chip. myfanwy 03:10, 16 July 2007 (CEST)
density of rapidobject polymer material
does anyone have an idea for the density of the polymer rapidobject (or any stereolithography company) uses? i would guess around 900-1,500kg/m^3 - the density of HDPE?
this will produce weight around 30-55g for the case?
PCB connections
The gumstix boards are designed to stack in one direction - perhaps a ribbon connector can be designed to allow them to be connected in a different orientation, possible making more efficient use of available space. --User:myfanwy
