Kurt Schulz of Cincinnati, OH, wrote in with with his Scooterputer project, which uses a Duemilanove Arduino, a custom “sensor shield” and a Liquidware touchscreen OLED display to add functionality to his whip:

* Battery voltage indicator
* Time and date
* Temperature
* Lean gauge with resettable max L-R indicators
* Current speed
* Resettable max speed indicator
* Odometer
* 2 resettable trip meters
* Latitude and longitude readouts
* Compass heading readout
* GSM/GPRS quad-band cellular module

Kurt did a great job of documenting the build, and provides tons of photos and diagrams to help you make your own. It’s sweet!
