Great work xee!

Here is my latest    Funny thing is with a certain resistance 1 led will draw 22uA or 10 leds will draw the same.

I made the following replication of kooler's circuit and it worked for me. I think the meters may not read the pulsed current accurately. So meter may read several times more current but that is still very low. The current must be low to have it run on just the capacitor.

Nice.. Have you tested how long it will run? I have a theory but don't have the parts to make this circuit yet.

the one xee2 posted.. i have solder one up it has been running since 1-14-10
it stills shows 1.48 volts the same as the day i stuck the battery in..
the new circuit i made runs the leds alot brighter but a bit more ma's
as you all seen that stprue has running..
i have a video i will post soon of the circuit running a led on the battery side..

here is the video i talked of
better camera
it has a 265,000 mcd led on the battery rail..
but the battery led will not light till you have a load on the secondary
