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)
