@jeanna

The results are only due to the core ,and fine tuning.

thank!

000OOoow weeeeeeeeeeeeeeeeeeeeee!!

lol

i found somthing a big toroide ... in an audio amp ..... it is green ...     

the ring is bout 1.25"

it is already wound 

heavey gage wire...  intresting how it is hooked up useing fets .....   hummmmm

look at that tagged 99 

rignt on the back i have this old tv tagged 66 watts

no i did not do this ....   

lol

Here is a crude drawing of the circuit I used in my last video.

I know it could be better with differant transistors but I use what I have.

Hi Slayer007,
They're 3055's aren't they?
Maybe you have the best for the job. HV switching transistors sound good to me.


I would like clarification on the joule thief portion of your circuit, please.
You say 20 turns single layer.
Does this mean this is a single wind of 20 turns, and the oscillating influence is coming strictly from the secondary?

thanks for any clarification you can give here.

If that is true, then why would you be trying different numbers?
I am watching your results with appreciation.

No,There is two strands of wire for the JT.
Two strands of wire wound by each other 20 turns
The pickup coil is only one strand.
Eight layers wound back and forth around 480 turns.
