JT Muller Dynamo scope shots.ASF
This shows the generator output signal on my Joule Thief Muller Dynamo running on one AA battery. Ferrite cores have now been added to two pairs of coils and I show the dynamo running on those pairs. One pair is driving the rotor and one pair is generating. The other two coil pairs are not connected to the circuit at this time. Adding the ferrite cores greatly enhanced the performance but makes tuning the rotor magnets to stator coils much harder.
