As you can see. When the Buz71 goes ON. The volt over A---D is only 0,05 volt. A transistor has about 1,5 volt and 2 transistors pnp/npn have 3 volt. This give 3 volt losses. Not good.
A mosfet Buz 71 need over 4 volt on the gate to go ON. Therefor the lithium lipo cell. The current to the reed and the gate is only 0,007 mAmp. This losses means nothing. The Reed will hold for ever.

Hi Larskro,

You can use the coil's back emf to charge a capacitor via a diode to power the gate switching circuit of your mosfet and get rid of the lithium lipo cell....

Hi everyone,

just to let you know that I donated out the last 3 RA circuit boards Groundloop had professionally made and donated to me for free distribution and mailing to help anyone interested in testing the RA circuit.

Thank you once again Groundloop for your kind generosity.

@oscar,

I already have a center tap at my generator coil. So I will try it out.

Hi Groundloop, I just want to second what Ben said.  Please stick around on this thread as well as your new solid-state thread.  We value your contributions.

Luc,

Thanks.

@Fleubis,

If I have any updates on my motors then I will post it here.

Alex.
