I'm in Riverside, CA and currently building a TriCopter flying Remote controled and eventually autonomous helicopter utilizing the Arduino Mini Pro 328 plus Gyro's from a Nintendo Wii and Accelerometers from a Nintendo Nunchuck, plus Sonar for height measurement.
I have friends in the Military UAV business and I'm just playing to see if I can match and beat their technology for 1/100th the cost.
Perhaps I'll end up with a military/law enforcement contract myself 
I'd be interested in a meeting and learning/talking/showing how things work.
Anyone have any projects for a show and tell yet?
