Joule Thief

Good video. You may be able to light a fluorescent tube with your circuit. I think you would be the first to do it with a self made Joule thief.

Ok i made some mistakes on the analyze of the circuit , all the pickup coils are the same except the one in blue that has more turns 38 all the others are 24 turns (core jt 2x4 turns per core), The same core can give up to 46 volt per side when used in a single circuit fashion, 3 on them show about 23 volts on all coils, those are better results then expected on the first try. The voltage on 0.4v is the same in all the circuit at every core.

Really really nice movie!

Pickup coils on toroid can multiply oscilating impulses but still needa to do something with charging part of circuit in order to send charge back to the same bttry.

Maybe 2 batteries is the way to go until 2 super caps could be put in place.
