I know nothing about the big coil, except he has 56 ohm. I just have "found" it somewere
But i'm testing with a metal coffee box and leds instead of the fluo. I can better see what happen. This coffee box can replace very well my big coil.

If you mean a piece of aluminium as ground instead of the copper pipe, yes it works too. I have a long piece of aluminium so long as the copper pipe (not so large of course) and it works.

I try to see if i can make it completely wireless with the cofé box directly on the output on one pickup side, the other side grounded into the wall.
The wireless "circuit" is the big coil near the coffee box connected to a led and the led to the copper pipe. It works but box and coil must be near. Maybe with a better antenna...i want to try water but hmmm i hope i will explode nothing

But the last video (N°3) is very strange, i'm so far away ,it can't be magnetic. I'm asking me how a wire with the end connected to nothing can circulate electricity. It's too far away to be something like induction with the other side of the pickup.

I think it's a single wire earth return in my video N°3. IT's on the wiki:

The coil after the fluo is like a ground that's why it works.  Same for the long wire, more long is like a better ground.

Yes, I think so too.
Very interesting. I am glad you are doing these experiments.

A coffee box, huh? interesting idea.

Hi everybody,

Here is my newest youtube movie... part 6 on this joule thief with 2 secondaries and 30 leds in series etc...

Please enjoy,

@ Jeanna:

Very well done!  30 LEDs is great.  I really like the way you explain everything in your videos, very nicely done.
