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)
