Joule Thief

Thanks. But reversing pins 10 and 1 cuts output voltage in half.

Do not just switch the 1 and the 10. Do the whole thing.

Do you think we could make lifter work from 1.5 to 9 v ?

Hi Mark,

9V into a flyback HV supply built like xee2 yes it should fly if built light.

If you balanced a tiny lifter on a long thin balsa beam with a razorblade fulcrum point then you may see the beam move at even 1.5V supply input.

24V input and it will be straining at the leash!

My  flyback  transformer JT is  a little  bit simpler than yours .
I use pins  1  3 and 10
They  are  hooked up  exactly like  a  regular jt .
The  3 pin is  hooked up  as if it was the  start and   end that  are  twisted together  on  a regular  JT.

I think this is the lowest power for lighting a fluorescent tube that I have seen. Only 10 mA from a 1.5 volt AAA battery. The tube is not as bright as it seems in photo, but it is more than just barely lit.

Xee2,
Would you be willing to draw this newest circuit in the form of a regular joule thief circuit?

thank you,

jeanna

Nice ! I just got a flyback my self , i would love it if you could find the drawing of your ac circuit .

I just can't find it .
