Joule Thief

@Groundloop: no, what would be the fun in that? But I have taken the failed transistor out of its socket and jumped the socket with wire jumpers.... and it doesn't do anything but drain current. No light.

@Gadgetmall: Sure, I've got the ghost light from earth ground and the touch antenna if that's what you mean? , but the power for the light is coming from the cap, I think.

Anyhow, here's the video demo of the weird tranny mode (rocky horror?); it will be ready in a few minutes. I'd really like to understand what is happening.... Just when I think I've got this circuit figured out, it throws another curveball.

@Groundloop: Just checking: the two halves of the Orange coil are wound in opposite directions, yes?

TK,

No. The primary and trigger coil is twisted together. It's a normal Joule Thief.
I was just a poor drawing. I do not remember if I posted any coil instruction back then.
I posted this circuit back in 2011 because I wanted to try the two battery mode
to see how long I could run the circuit.

if you guys seen my video , ignore it (http://www.youtube.com/watch?v=N1Fj4r-we84). I also show a few times the cap voltage increasing but no light at that level.

@Fausto: Ignore it? No... it's an inspiration! Kind of long... but this circuit demands long explanations I suppose. Thanks for sharing, I subscribed...
