Levitating LED combines wireless power transfer + magnetic levitation

Chris Rieger is an Electrical Engineering student from the University of Queensland Australia, and has been experimenting with wireless power transfer and magnetic levitation. After studying the work of Jeff Lieberman, Eric Taylor, and others, Chris fine tuned his design to combine these two technologies to achieve the results depicted in this video. Visit Chris […]

Arduino magnetic levitation project

mekonik has published complete details on his Arduino magnetic levitation project. Not content to settle for a typical “hello world” LED blinker as his first project, he supplemented the Arduino with an electromagnet, Honeywell SS19 Hall effect sensor, MC3401P op amp, NPN transistor and 1N4001 rectifier. The circuit essentially uses the small Hall effect sensor […]
