Joule Theif problems. Please help.

[chrisburrows]

Hello,

I've been trying to make a joule thief to light a CFL globe from a AA battery but just can't seem to get it to work.

The globe lights up, but flashes instead of just staying constantly lit.

Here's a video: http://www.youtube.com/watch?v=1Hl3vL0p8Sk

The circuit is from a no-name camera brand called Super Snaps. Any help would be much appreciated.

Cheers, Chris.

New to this so can't help much but interested to know how do you manage this. I will definitely learn something good from this.

It is really very simple. Or at least it should be...

But I just can't seem to get mine to work. If anybody knows why, I'd love to hear about it.

Thank you in advance

Do you have a video on how you modded your camera circuit?  I was only ever able to to get the Fuji AA circuit boards to work. Possibly, your board does not have the Fuji large transformer?  If the light goes on and off it may indicate the board is utilizing too much resistance, like we saw on the simple JT circuits using variable resistors to tune them.

The only modding I did to the circuit was to solder the flash switch down. I am not using a Fuji camera circuit though. Just the circuit of a cheap no-name camera.

Do I need to take out the circuit for the CFL? I just tried that then but now nothing happens. I may have damaged the globe doing so though. There were 4 wires inside the globe (2 groups of 2).  I'm not exactly sure what I was supposed to do with these...
