Joule Thief

@ Gary:

Why not just use induction and get the full cycle in both other coils at no extra cost?  As long as the fields overlap, there does not need to be any wired connection and now you get 2 coils running full cycles for the cost in energy of one.  I have not tried this yet, but I will.  I read this in one of my electronics books on induction toroids.  Just my 2 cents.

I have not got to the part where  some of you are lighting  LEDs  with one  tirn  and  apparently not  loosing power by doing it .
If it was  that simple every  transformer  would be OU .
I am not saying  that it can't be done ......  I am  saying that I can't  do it yet .

ok to get this correct the coils look proper now no jt ....  i need to use a freq genny on sine wave to match  the ressonance of my input winding...  all else flows down the line ....

does  this sound correct .. ?

ist!

building...

IST,

Yeah, I think your right. A joule thief will not work with this setup. The jt is only pulsing a DC voltage there is no AC sine wave. This is why the LED's on your 1 wrap output are polarized.

  Gotta agree with Mr. Magg.  It would be real lucky if you could get the pulsed dc clocked out to match the primary impedance.  It may work though if the core is run below saturation.  It won't give you as much bang for the mass but might be good for a demo.

well lets make it work 

can some one that has the skills and materials build the other half lol     the pnp 

then we get amped sine from square ........      they must fire at the same time ...  then send em down the line ...

but this will be a tricky task ... as the out put of the jt's must match the freq of the exciter coil but this is no toy when done correctly ...   in my opinion ...   

ist..

will hook the unit up to the freq genny ...
