Selfrunning cold electricity circuit from Dr.Stiffler

The video & sound are working 
Thank you

I can not see it yet myself,
but I uploaded the original AVI now also over here:

There you first have to paste in this 3 Number code into the form,
then wait a few seconds and then the download link will apear.

Hope this works out now for most of you.
Regards, Stefan.

Touch the wire that goes to the mesh,  to the  ferrite core .

Here is my first n00b attempt in replication. Yes, I know I've done some things wrong but I was just too anxious to get some results...

I had to quickly build a signal generator so the cyan rectangle is the MAX038 driven ~10MHz sine signal generator (pathetic one as well used the spec. sheet circuit so it's pretty noisy as well)

Yellow rectangle is the Fig.01 circuit from doc. stiffler's webpage. My L1 is I hope around 2uH (grey cylinder thingy lower right corner of yellow rectangle). Since I do not have a precise LCR meter (Masterch DMM I have is pretty lousy and won't measure that low) I just picked something close enough, I'm sure if I had the right 2.2uH the LED would light up brighter.

My AM core is around 700uH taken from an old alarm clock with radio. I think you can use any kind of an old alarm clock with radio and butcher it up for the core, as long as the physical dimensions match.

Now, at first I did not have anything underneath (aluminium plate) but I noticed that it seems to be an integral part (most important?) of the circuit because after putting a small piece underneath and aligning it a bit, the LED lit up brighter.

Next step will be to put this on a real breadboard (I was lazy to do it originally since I already started the circuit on this tiny one). But hey, it works for what's it worth - just proves that you can make a terrible hack and still get something out of it. Thanks to doc. stiffler for making us use our heads...

Hmm,
I myselfcan also not watch it yet over here in
Germany via the Versatel Internet provider,
where I have my DSL line...
Hmmm...

Seems Google Video might have different
server throughout the world and it has not gone
through all of them.

Ironhead, when I touched a few cables at different places, the light got weaker...

Instead of the metal mesh I justcan also run it versus my grounded scope.
The signal generator is not grounded. It is floating !
It has no ground connection.

I measured the voltage directly at the LEDs and it is
almost a sine wave with plus 5 Volt and about minus 3 Volts peaks
at the resonance frequency.
So although I put in a 0 to 12 Volts square wave via single wire from
the signal generator, I get almost pure AC
at the LEDs.
