 Supplying Power to a Rotating Object, Wirelessly!

There are times when an animation includes a rotating object that needs power to light a bulb or LED or to operate a motor or some other DC powered device.

This has traditionally been done with slip rings, a set of round contacts and brushes.  While this works the brushes or contact surfaces need to be carefully aligned and can wear over time.

I have been experimenting with the circuits that are used to wirelessly charge a cell phone and have found a very simple way to use these devices to transfer power wirelessly to a rotating object.
