Self running coil?

This is not a boost converter as none of them will recharge the input source(cap) while being operated. Ive tried.
And you wont find any dc/dc converters with magnets on the coil core.  ;]

Indeed!
I'll pass that information back.

That led test may not prove much. When you put the led on the mosfet, you are providing a new current path with the led that wasnt there before, and the leds brightness will be more at higher voltage of the output than the voltage produced by the sig input, kind of like a jt. I would not go any further to prove anything, in fact, I am thinking you can use a pickup coil to provide input to the mosfet to replace the signal gen. Maybe a variable res to match the pickups output to the fet.  And the phase relationship can be easily reversed to give proper pulse to the fet from the pickup.  ;]
This might be real easy.

BTW, did you attend a Thane Heins' Perepiteia demo about 2 years ago?
At the time he had recently got permission to set up his Perepiteia in a undergraduate EE lab. I was there and a few others along with a student reporter
from the university newspaper.

Hi Luc,

Your diagram appears to show your Toroid as split. Did you get your Toroid in two pieces, or did you cut it yourself? If so, what kind of saw did you use, and do you know the thickness of the cut or "Kerf"? Thanks for efforts.

P.S. Not sure if you saw my comment about your halogen desk lamp on video 5, but I was hoping you could turn it off, as a test (these lamps can create surprisingly large electromagnetic fields).

Hi derricka,

no! the toroid is not split, the line is there just to show it's two coils. I wish I could buy them split!!!  make a toroid in no time

I saw your comment about the light. It's not the source of the power. Do you not hear me switching it on and off in my video's to better see the scope shots and the circuit keeps working?
