A great thing about college demonstration projects is they don't have to have any commercial prospects. That's a good thing for students at the Milwaukee School of Engineering, who call their model an anti-gravity device. Despite that moniker, the machine uses the same principles that let high-speed magnetic levitation trains float above their tracks. The MSOE levitator uses analog instrumentation amplifiers donated by Analog Devices, a pulse-width modulated H-bridge from National Semiconductor, a coil, a feedback control compensator and Allegro MicroSystems Hall-effect sensors to magnetically suspend an object in mid-air.
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
