Arduino FPV RC flight instrumentation

If you haven't heard about FPV flying, check it out: http://www.rcgroups.com/video-piloting-fpv-rpv-469/

I'm using arduino to display low battery voltage warning and ground proximity (with a ultrasonic sensor) in flight. Here's a video: http://www.veoh.com/videos/v8567662mGXeNbNN

Like the "pancam"--nice track in the background too.
