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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
