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.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
