The High Altitude Rocket Telemetry Payload system is a flexible flight computer for mid- and high-powered model rockets. The ATmega169 based system features a GPS receiver, a wireless data telemetry downlink, and a pass-through bus architecture that enables you to configure a payload for your specific flight goals. For those rocket geeks out there, this might be a interesting project. I do know that most of the rocket parts are buy-ed from the shelves of the hobby stores, but you should definitely try build some of the parts, you will get more satisfaction when you see it fly away with the parts you fabricated.
