Second Stage Joule Thief Circuits

jeanna
are you talking about the ccfl driver circuit.. running with a 1.5 battery

or my 3.3'' toroid  ( jeanna style ) jt
it has 26 awg secondary and a 18 awg litz primary

let me know i will stick the oscope on it and take a pic or video tomorrow..

oh.. if you are wanting me to scope the output of the discharging cap.. my scope won't read it

let me know

I was thinking that since you cannot get near it with 6 volts, maybe you can with 1.2v.
I certainly don't want you to damage your scope.

What about putting the scope on each leg of the filament wire? Is that too hot too?

Thank you,

Posted this in the Jule Thief thread, really belongs here:

Identified the neon cap charger trick; and it shows several workarounds. Reminds me of capacitor timer circuits, use the discharge timeframe on one to charge another.

note:
(transformer turns ratio) 270/2 = 135to1 x (unipolar) 6Vdc = 810Vac pp (peak-to-peak).

@all
a 60 watt is a bit more of a pain to light due to it's low resistance to light up .. once i get the ma's draw down and it is safer, i will post a good schematic.. but right now there r some safety issues.. or i just been having a bad couple of days..
my whole goal is to make something that you could run on a solar panel for days even if the sun hasn't been out..
it always good to dream.. right
i would love to get it back down to a AA battery.. but with this it is too much ma's
