Levitating Lamps (and Other Objects)
How can you make objects levitate effortlessly in the air, to all appearances? Electronicists will naturally think along the lines of (electro) magnets and mutual repulsion. Unfortunately it’s far from easy to devise an arrangement that provides stable, long-term levitation. This article describes some experiments and schematics for achieving something of this kind. It also shows a method for integrated inductive energy transfer to illuminate LEDs aboard the levitating object.
