I have completed the Beddini school girl circuit experiment (Fig A, Fig B), now would like to continue to make further experiments, the main hope that the circuit power consumption as small as possible, efficiency as high as possible. But do not know what kind of circuit structure is relatively the best. Very much hope that you all recommend a good circuit.

Learned a lot of description of this forum own feeling is that the Beddini window motor power consumption smallest, efficiency most high, is it?

The window motor [Fig 1] and [Fig 2] Which better?

Experiment in what skills?

Thank you.
