Linux-Powered Amateur Rocket Goes USB
This very simple code could be extended to make all sorts of USB devices. The isochronous IN endpoint could send sensor data like temperature, pressure or GPS readings. It also could send video, still frames or audio data. It even could be hooked up to a motion detector. The possibilities are endless with the Olimex's breakout board.
If you want to follow the Portland State Aerospace Society's development of LPC2148 USB avionics sensor nodes, join the psas-avionics list (see Resources).
PSAS hopes to do an airframe-only launch in Bend, Oregon, this summer. Our goal is to have working USB avionics nodes and a working Linux flight computer by October 2009. On October 2–4, the Arizona High Power Rocketry Association hosts the BALLS amateur rocketry event. If you're at the BALLS event in the Black Rock Desert of Nevada, or if you're still hanging around after Burning Man, stop by and say hello.
