Bicycle

Dynamo powered openmoko (and other USB-Devices/Host) using the frequency/voltage of the dynamo to gather information about speed and distance.

Wishlist for this USB-Charger:

• 5V, 500-1500mA output (through diodes or MOSFET)
• Voltage, Frequency (should be dynamohub independable)
• USB-Device (maybe with USBprog)

nice to

• 3d compass, altimeter, thermometer (with information of distance to map tunnels, dense forest, ...)
• buttons for turning lights (on lowpower/on highpower/off), setting waypoints/audionotes, easy navigation of openmoko (scrolling/enter)

Enscribi on OM2009

Step 1:

opkg install http://www.opkg.org/packages/zinnia_0.04_armv4t.ipk
opkg install http://www.opkg.org/packages/0_zinnia-tomoe-ja_0.6.0-20080911_armv4t.ipk (for Japanese support)
opkg install http://www.opkg.org/packages/0_zinnia-tomoe-zh_0.6.0-20080911_armv4t.ipk (for Chinese support)
opkg install http://www.opkg.org/packages/enscribi_0.2.0_armv4t.ipk

Step 2:

Create symbolic links for the old libs (tested with om2009-unstable 17-Aug-2009 17:19) If enscribi is linked against the new libs then these symbolic links are obsolete.

ln -s /usr/lib/libecore_evas-ver-svn-02.so.0 libecore_evas-ver-pre-svn-01.so.0
ln -s /usr/lib/libecore_fb-ver-svn-02.so.0 libecore_fb-ver-pre-svn-01.so.0

ln -s /usr/lib/libecore_x-ver-svn-02.so.0 libecore_txt-ver-pre-svn-01.so.0
ln -s /usr/lib/libedje-ver-svn-02.so.0 libedje-ver-pre-svn-01.so.0 
ln -s /usr/lib/libembryo-ver-svn-02.so.0 libembryo-ver-pre-svn-01.so.0
ln -s /usr/lib/libecore_job-ver-svn-02.so.0 libecore_job-ver-pre-svn-01.so.0
ln -s /usr/lib/libevas-ver-svn-02.so.0 libevas-ver-pre-svn-01.so.0
ln -s /usr/lib/libecore-ver-svn-02.so.0 libecore-ver-pre-svn-01.so.0
ln -s /usr/lib/libeina-ver-svn-02.so.0 libeina-ver-pre-svn-01.so.0

Step 3:

goto "setup" --> "keyboard" --> "enscribi"

To get a Chinese/Japanese input method. Ensure, that you have Chinese/Japanes fonts installed.
