Selfrunning cold electricity circuit from Dr.Stiffler

Ok Fausto,  take a look at the diagram. 

After giving it some thought, I think the SERIES capacitance of the diodes and the SERIES inductance of the wire are the key players in the resonance. 

The stray capacitance to ground from the person at the other end is also key.   Thinking in terms of antennas,  we can load the top of the antennas with a larger sphere then the diameter, to tune the antenna, or tesla coils have top hats.  Anyway, it's just a place where the currents can flow into with little resistance.     That's what you are doing  by touching the wire or by hooking up the spool of wire to it, you're providing a low impedance SINK for the current.   Hope this helps.

PN100 is the NPN, PN200 is a PNP...............

(remember the model is approximate.  There is what is know as distributed parameters, like in that link you posted on transmission lines, and that's what the transmission lines are.   However here we're operating at sub wavelengths so we don't have to invoke reflection coefficients just yet, but we're at high enough frequencies where interesting resonances can occur,  resonances which we didn't consider at lower frequencies)

Dear Non-Classical Researchers,

Here is an example of a Thomas Driver operating 65 (out of 92 avaliable) very old LED's that have been soldered to a Radio Shack circuit board (Cat No. 276-170) elevated a full 3" above the bread board. The Ferrite Antenna Loop stick is elevated 1.25" above the bread board as well. The switching transistor is a 2N4101 (it gets hot). Feedback capacitor is Silver Mica 56pf. Starting Resistor is 220K. The "primary" winding is 9 turns of #24 AWG magnet wire. Using a 12 volt 6.2 Ahr Gel Battery decoupled with 1.0, 0.1, and .01uF poly capacitors. AV diodes are IN4148. Analog DC supply current 70 mA. (Take that reading with a grain of salt since this is a DC meter - RF meter coming) The 190pF collector to ground bybass capacitor has been omitted.

No claims of OU or effective operating power levels are made here, just that this circuit will illuminate several LED's without the complication of parasitic capacitance introduced by the bread board. Such was not the case with my early experiments with this technology just a few weeks ago. Apparently the Thomas Driver can provide a power level sufficient enough to swamp the observable effects of the distributed capacitance that were experianced in the past.

Submitted for your consideration,

Quite  a number of you have these circuits now but again i ask please to add super regen quenching to the oscillator. As explained several times now the 5Khz hash on the TPU is almost certain a result of quenching because this raising the Q gain of the ferrite bar OR torridial cores by hundreds even thousand percent. Thus any extra power which is being sucked into the circuit when in resonance will be in abundance and thus will be the second stage to a self running circuit. The current gain of 150% to 300% may not be sufficient to loop back to make it self running without quenching due to feedback loses. What should happen like most high tuned circuits is the input power should drop dramatically as Q is increased while output power increases dramatically. This is exactly why super regen radios of over 50 years ago can accept a signal a small as 10uV and within the space of a single  tube amplifier oscillator use that to drive a loudspeaker. Think about this!! In theory at least i expect you to achieve uA input power and still run 50 LEDS.

Its very easy for those that wish to take this the the second level!!

@bolt,
Do you happen to have a copy of Idiots guide to super regenerative quenching? Wikipedia does not describe this very well!
Failing that, please point where you may already have discussed this.
