Joule Thief

[kooler]

Thank you Kooler, you may be right, the transformer only has 4 pins.
Bummer, I was hoping it was a Fuji AA, One day I may get hold of one and be able to fire up a string on LED's.
Until then I will continue collecting used Cams.

you make the AAA fugi light a cfl.. but you will need to dismount the transformer from the board or you can just rearrange the components you will need a pot were the resistor is on the transistor and if it has a small led on the base.. take it out..
and hook the cfl to neg on batt. then hook to the output of the transformer in front of the diode..
adjust pot till it lites and it should be pulling about 89-105 ma's from your battery..

That made under the scheme which is your forum has been taken, a small toy (a very good toy works) on the bifilar coil.
But I do not iron nraivtsya, I want to peredlat iron core.
Video and circuit inside the video - for povtoroeniya experiment, can someone be interested.
PS
hlchu also now having the oscillator spark economic examine the effect Hatchinkinsa

Very nice toy. Excellent results from two AA batteries. Look at:

'Great work on the JT Tesla coils.
I had thought that something like that was possible but have not got far enough to make one,

In the third video at first I thought that your Tesla coil primary was a CFL tube ..... now I am wondering if a CFL could  work as a primary coil and spark gap at the same time.
