Joule Thief Dream Coil

I have to agree with all of the other responses you have received thus far.  Now I just got done winding a 3/38" OD toroid with 330 winds of 28 ga. mag. wire and if someone has a toroid winding machine that could have done that in minutes instead of all the hours it took me, that would be a good thing.

Like Jeanna said, if someone offered a kit with the large toroids, or any tested toroid that worked with the Jeanna Light circuit, then I am sure some folks would buy pre-wound toroids.  At least pre-wound with the large number winds of the pick-up coil. (In this case, 330)  the other winds are no problem for folks and only take a few minutes and, by varying the base turns and the collector turns by the builder, it gives more flexibility to the project.  So, I agree that a kit, or partial kit for the Jeanna Light with the high turns pre-wound would be the way to go...at least for a start.

@all this dialog is exactly the information I was looking for... Lets start with the perfect jeanna light coil. 11,000 permeability, diameter?, ferrite core only, 330 turn secondary (guage?), 11 turn primary (guage?).

I know I could look through thousands of pages to "get close" But I want something consistant.

I am sure I can get whatever is available.

My goal is not to mass produce toroids. But to create sellable kits... Like my Unzapped Cell.

I would also like to produce a jeanna light kit, and possibly a candle powered emergency light. All three will need different toroids. But I think they will all mostly be the same... less turn on secondary, etc...

Maybe even eventually battery reviver.

BTW I have been digging for hours now trying to find the jeanna light circuit... could someone please post a link to one for me...
Thanks

Here is the link to Lidmotor's Jeanna Light video.  In the beginning, he shows a good still shot of the circuit.  This is what I used, more or less, for my replication:

I am sure Jeanna can give you links to her actual circuit diagrams...I am sure they are somewhere, but I don't know what page.

@all this dialog is exactly the information I was looking for... Lets start with the perfect jeanna light coil. 11,000 permeability, diameter?,

I used the OW48613TC from MMI.
It is 3.35 inches OD (86==86mmOD x 13mm=height)
Other companies make these and maybe your friend's company has some too.
I have another that works which is OW46113TC and it is 2 1/2 inches and 13mm height.
The permeability of the W is around 14,000 on this one and for some reason that has to do with OD this matters, but I dunno.

ferrite core only, 330 turn secondary (guage?)

I used 28 awg.
Lidmotor used radioshack red which is awg 30. I prefer not to use the rs red for these because the varnish is too thin and breaks occur too easily. One break in the varnish and your coil has a lower voltage. And to make it worse, the spark may be sooo small you cannot see it.

, 11 turn primary (guage?).

The gauge I use is awg 24
On the big ones I use telephone 24 g wire with its thick plastic coating.
On dressed up tiny little ones I use awg24 varnished wire.
It IS possible that the amps draw will change with a fatter or thinner wire.

This is so wonderful
I could ask also if you were interested in stocking the toroids for us(=experimenters) to buy from you unwound, because we are faced with a $30 minimum for a  toroid purchase from the MMI distributor that I found .

I would also like to produce a jeanna light kit, and possibly a candle powered emergency light. All three will need different toroids. But I think they will all mostly be the same... less turn on secondary, etc...

Oh how the world can change! yeay!!

BTW I have been digging for hours now trying to find the jeanna light circuit... could someone please post a link to one for me...

Here is the most basic version on my desktop.
Bill just gave the specs and here is how it can be drawn.
I believe it is what you need.

Remember to remove that light between the C and E of the transistor after you find that the circuit is soldered properly.
The only lights should be between the wires of the secondary.
Start with 3 turns only, when checking a new toroid.
Expect about 7v for each led and remember there is often a polarity with the secondary.

thank you,

Perfect !! Thank you so much! I have found this circuit jeanna! I am lighting my generic single LED flashlight with it (unzapped cell) Thing has been running for DAYS from the secondary HAHA!

I will be sourcing the torids this week. Also... I can have the secondaries pre wound... leaving only the primary to wind by hand... This could be nice.

Thanks!
