The wireless power transfer setup consists of a single wire ring connected to the power source (a hacked benchtop unit made from an old 350W power supply unit and banana plug ports) and pulling 0.5A at 12V. Send and receive coils were then tuned to matched frequencies.
The drive coil and wireless mechanism are hidden from view inside a wooden enclosure raised on two cardboard box columns and, with the power switched on, the LED light floats in the space underneath.
Rieger says that when the power to the levitating system is turned off (or in the event of a power failure) the LED light unit jumps up to attach itself to the base of the wooden box rather than falling to the ground.
Describing LevLight in words is all well and good, but it really needs to be seen to be fully appreciated. To that end, have a look at the demo video.
