Poor choice of wording

I think they mean "mechanical", generating the electrical power from the rotation of the yoyo. It isn't as easy at it seems, the magnets have to spin at a different rate to the 'core' for it to work as a dynamo.

Hi,

Try something with Neodymium magnet, coil and supercapacitor.
