Joule Thief

I found that if I jostled the primary to much the voltage would go down , often by 10v. And jostling the primary is easy to do.

I know you like high frequencies, but at frequencies over 100 kHz parasitic capacitance between leads can have an effect. So each time you change your leads a bit the results change. That is why RF circuits are usually built using PC boards.

Oh.

Does that mean a spark?
Do I need gutta percha? 
NO! NOT the boiled oil!, please anything but that! 

I will be specific. The kind of change that seems to make the difference is having the last bit of wire tightly wound or loosely wound against the toroid core before it goes into the C or E. The wire on the  C mostly made the difference today. I suspected that the reason was that this Collector coil was best somewhere between 1 1/2 and 2 turns. If I made it too close to the toroid, the voltage went down by 5v.

The other thing that made a big difference was getting the pickup wire on the wrong side of one of the crossings between the split coils.
Probably this capacitance thing again?

I do not know what parasitic capacitance means, and I would like to.

thank you for the drawing and
thank you for your help,

i have been haveing a hard time duplicating my results agin with 2 freqs...  today


the reason is .... 

yes the batteries went low  and after they get to low the effect ceases ...  no matter what you do as i have seen

im useing 3 button cells so i bet 5 v will work awesome ...   

so i have been assembling my solar unit   im thinking of a few cell fone batteries .. but i have a 4.5 volt unit that came with the 3 pannels ..

i will switch the buttons for a nicad solar ...  not tryed that yet i would expect the results to be the same .. tho

aside that the thing works good ...   and yes even the same result no matter the wires... (pick up coils... )   1 2 10   lol

the  wopper wave is the same on all out wires...  but the wave is not seen on the jt flyback ...

ist!

few more pics 2 outputs scoped from 1 coil

scope 10v/d

i added another neo to c what it would do ....    (last 2 pics)  magnets 180 deg of each other

Wow ist,
Those waves are sooo beautiful!

I am sorry to hear you are having trouble replicating eesh your own stuff.
Are those rings from now? Or is this what you are trying to replicate?

i just took those pics


the poroblem was the voltage droped as i just explained above ... lol 

a constant 5vdc should provide constant results ...

the last 2 pics have neos 180 deg ... 

ist!

LET ME KNOW WHAT YA THINK .... 

near as i can tell right now ...  this unit is voltage and resistance dependent ...  as the voltage drops in the 3 button cells you must re tune it a tiny bit  to keep it in tune ... 

to eliminite this it needs a constant supply ..  that does not varrie ... if this is then the true case ..  it can be done at any voltage ...
