electronic dice without battery

The project will shows you how to build an electronic batterless dice. As the tube is shaken, the magnets traverse the length of the tube back and forth, thus changing the magnetic flux through the coil and the coil therefore produces an AC voltage.

The muscle powered voltage generator is based on Faraday’s law, consisting of a tube with cylindrical magnets. The tube is wound with a coil of magnet wire.
