I'm about to test an extreme version of a BalloonSat flight computer. It uses a BS2p and a MAX186 (12-bit ADC) and will run many more experiments than is normally on a BalloonSat. This is for a BalloonSat where multiple teams design experiments and share computing resources. It includes a GPS port for any experiment wanting to knowthe time/altitude All it needs is a radio/TNC to be a full up flight computer with tracking capability.
I envision tis being used by an entire classroom.
