How high can you go? That's a question that model rocket enthusiast Jerry Baumeister wanted an answer to. Cheap enough to be used in even "risky" launches, Jerry's battery-powered device features a circuit designed around a Flash microcontroller that performs an analog-to-digital conversion of the voltage produced by an absolute pressure transducer. Altitude and operational data is then output to two LEDs. Since the output is in A/D units, Jerry just has to do a quick mathematical conversion and he's flying high. Or at least he knows if his rockets are.
