my Muller Dynamo with all the coils.ASF
This is my Muller Dynamo running with all the coils on it now. One pair of coils are driving the rotor while the others are all generating. I show it here running on two AAs and drawing about 150 mA. The loading of the dynamo is shown using a 50v 1000uf capacitor, a white LED, and multimeter. A small AM radio is used to listen to the RPMs as the device is loaded. This is not very efficient at this stage and is still not correctly assembled. The coils are incorrect and the method of firing is still a simple reed switch instead of an electronic circuit.
