----- Original Message ----- From: "stanton54" > See http://autopilot.sourceforge.net/ for an excellent (although rather > complex) system. It uses a combination of gyroscopes and accelerometers. Any idea where I can get those gyroscopes? I assume that's what the little metal cans on the smaller boards are. I remember reading an article on those gyros a long time back, but I never followed up on it at the time, and I've now lost track of the article. IIRC, they're some sort of piezo gyroscope which works by vibrating rather than by spinning, or something like that... Can anyone give me a website, part #, price, etc.? - Robert -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
