Selfrunning cold electricity circuit from Dr.Stiffler

Hi Ron,
will figure 22
with the picture:


still light up all the LEDs,
if you shortout L1
and use your faraday cage around it and
just have a ground wire going to it there at L2 ?

>2. What will happen,
>if you shortout the 400 pF cap in:
>Fig: 26

The LED is a bit dimmer. The cap is not forming a series resonant tank.

So it seems it is just the coil-core resonance
which are doing these effects, not the
external caps together with the coils.

I will build myself a square wave generator up to around 20 Mhz
and see where the resonances are with my ferrite transformer
and a few other ferrite cores I still have laying around.

Regards, Stefan.

In this configuration, shorting L1 will reduce the amount of energy to the LEDS. They will light but very dim.

In this configuration the two Al plates are forming a parasitic amplifier in between the generator and the circuit. They allow for a very low drive from the generator. Removal of any one plate will kill the effect.

So the signal generator
was always running in the background ?

Also in this figure 14 case ?




What did energize the coil-core  combination then ?

Just some 60 Hz "noise" from the ground wire ?

Getting somewhat concerned about what you do not understand, or do not want to. Where in this diagram do you see a parasitic plate or a signal generator.
Please stop trying to change or put works in my mouth because I will not just jump to the end.

Thank you Dr. Stiffler and Stefan for your replies.
