Selfrunning cold electricity circuit from Dr.Stiffler

That recording just sounds like garbled noise to me, I think you'd have to try pretty hard to get something out of it.

Anyhow, I've got the thomas oscillator working (I finally received my coils). So far, i've only got a voltage of 32V out of it, but thats cos thats all the LEDs I have to use. I'll be buying a lot more LEDs tommorow, and will give an update on the results.

A weird effect I just noticed, is that if you switch the polarity of one of the LEDs in the chain, then while that LED turns off, all the other LEDs remain on, at the same brightness. Seems a bit weird...

Instead of making a simple in series chain of all same polarity facing diodes (LEDS), try making a series "AV" plug from the LEDS themselves.

That is, bypass the signal diodes altogether, kill off the capacitor in the AV circuit if your using one, they are not needed, and instead connect one end of the secondary to a series of "AV LEDS" which is simply one LED facing one direction in parallel with another LED in the opposite direction. 2 LEDS in opposite direction make an "AV LED". Now simply hook up as many of these "AV LED" pairs in series as you can. I have 50 Leds making up 25 "AV LEDS" and the interesting thing to note is, each pair of LEDS adds to the total brightness of all the other LEDS as the plug chain grows with each added "AV LED" pair. At the end of the chain is a 20 cm piece of wire.

Another interesting thing is that the LEDS dim if they are connected from the end of the led chain in a closed loop to the other end of the secondary. Not sure what to make of that, probably just de-tuning. The resonance seems to self - adjust to each increase (decrease?) in load when adding the LED pairs, when the loop is open.

Oh yeh, I'm using a simple blocking oscillator AKA "Thomas" running on 12 V supply. Small PNP transistors, (x2) to share the load. Primary of antenna connected in series with a 600 ohm centre tap transformer in place of "L1" as a choke. Helps to protect those little transistors by limmiting the current through the primary, but enhancing the voltage in the total primary loop.

My Antenna windings are completely unknown!

It's a sealed unit, but there is a schematic on the outside showing it consists of a primary, with a centre tapped secondary.
Core is ferrite approximately 80 mm long by 8 mm diameter - from what I can see?  And that's Not Much ! 
Shows how wide the parameters for this thing may be!   

A Strange circuit indeed! Interesting for sure! And oh yeh, it's got bite when you touch it in the wrong place lightly. Ouch
Bright lights making me dizzy...............KneeDeep

@All,
Please take care as some LEDs ( specially the blue ones ) can emit UV light which can damage your eyes permanently.

It seems that the current in reverse polarity thing is probably just that the circuit puts the voltage to a level which can pass current through an LED. I haven't got a power supply which can supply 40V, so I can't test this, but it would be great if somebody else could...
