Chris Rieger, an EE student at the University of Queensland, built this light that both levitates and gets its power wirelessly.
This is a project I’ve been working on for about 6 months now next to my regular studies. It is a levitating light bulb. This project came to life when i saw Jeff Lieberman’s implementation of it a few months before starting. I was fascinated and started research on building my own, reading many academic papers and spending long nights reading up on pretty much every project which included wireless power transfer or magnetic leviation. What I found is that there are many many existing projects of both, but only a few have combined both these technologies. Once you have both working it’s really just a matter of overlaying them. The high frequency magnetic field generated from the wireless power transfer circuit does not effect the leviation aspect of the build.

i’m not saying that this is a magic trick, but *if* one wanted to do a mirror box levitation trick one would set it up in a box and initiate the levitation in the dark ;)
The cool part about this project is wireless power, the levitation is kids play. BUT set up in a nicely designed box the entire concept could be the next lava lamp and plasma ball rival.
Doesn’t the the heat from the LED heat up the magnet and thus change it’s property so it drops?
Hi
kinda cool
The best part of this demo is the stand for the demo. Two old sun hard drive boxes. Got to love makers.
