Self Running Micro TPU, with closed loop.

Those are good results to start that's for sure.

Still no good. It seems something went wrong with my circuit for some reason as nothing works now. Will try other components.

Once I wind a coil over the bifilar, this will leave me with a coil that is bifilar plus the two other coils. The bifilar having four wires, I will try a mobius loop by  putting the opposing wires together and connect the two coupled leads to the circuit. This should cancel the resistance of that coil. Maybe good, maybe not.

Just to get this straight one more time, btentzers circuit is the same as EMs expect btentzers transistor is switched around so the emitter is at the collector and vise versa. All I do is switch the transistor one way or the other but still no go. Geez. Now I am convinced the ferrite is very important.

If you guys look at the Faux Pas thread last few posts there are a few links that are totally great. One on general electronics that you can download 6 volumes and the other on magnetism, etc.

In the magnetism pdf, it says that with an iron core the coil magnetism and the iron magnetism is "additive". Say whaaaaaat?

So I guess the ferrite types are made to hinder to a certain degree the total magnetic saturation allowed to give certain input/output results. If at the low voltage levels we are working at, ferrites still do some cancellation, then maybe iron is the best way to go.

What happens if you replace the trigger coil with a 150ohm resistor?

@wattsup: Try an old torroidal transformer core from a computer  smps - that worked fine.  And most important is the wire - make sure it isn't copper...

any good?

@eon
Does that wire have insulation?

@all
Know of any online sites that sell 20 gauge iron wire?

Thanks,
