Thanks xee2 for posting the drawing of the circuit.

Yes, that seems to be the circuit.
The question is, if the primary windings are 2 x 20 windings
or 2 x 10 windings.

Maybe Lasersaber can confirm this ?

Regards, Stefan.

????????????????

2 x 20 windings = ???? mm
    750 windings = ???? mm
????????????????????
THANKS....

It's 2 x 20 windings.  I have not measured the wire gauge.

I updated my website with more pictures and a source for the bulbs.

More to come soon.

Hi Lasersaber

thank's for the new pix

ouch!! the 750 winding probably some hours of hard finger pain.

Any knews about the material of toroid , can you confirm that it is  METGLAS , and if yes any idea where you got it?

I have made some testing with my TV toroid (the biggest i have at the present ) I could light 1 LED bulb as yours but not very bright , but i think to do better this next times. Just for fun i get enough electrical exitation of the surrounding in my shop that i remember the Slayer experiment.

Will go on the test, very interesting. Just for info my actual secondary is made with 7 stranded 0.125 mm copper (Romero's purpose ) and i separated each strand to make different testing. With only one strand i could lit the LED bulb. So yep let's go on.

Thank's for sharing
