This is a straightforward way to add an LED demonstration to your small engine. Uses the coil from an synchronous motor as an alternator coil and 10 neodymium magets on the flywheel. The exact size of the magnets is not too important, anything from 8mm dia x 5mm thick upwards should work.

A steel backing for the magnets is much better, but I fitted this to a cardboard engine as a proof of concept.
