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.
