Joule Thief

@ jeanna

So xee2,
I am still unclear about what I would be doing if I connected the ignition coil.
I see in your drawing that this transformer is connected to the battery pos.

I do not know what else I can do to help you. Remember, I have not done this. But this is how I would try it.

Is that what I would be doing if I connected the ignition coil to my joule thief?

And, can you please explain why you would connect the wires of the primary and secondary in a transformer coil like that?

The two coils of the transformers are connected together that way in the ignition coil.

EDIT: I think it would be best to start with a JT that has 10 turns for base coil and collector coil and then see if the number of turns can be reduced.

EDIT 2: In a car, a switch pulses current into the ignition coil. The idea is to replace the switch with the JT and have the JT pulse the current into the ignition coil. In my circuit the idea is that each time the JT turns on it sends current through the ignition coil primary.

Why not start with this circuit and get it working. When it is working replace the toroid transformer with the ignition coil.

I have tested this circuit and it works. I have not substituted ignition coil.

@ Bill

Thank you for the kind words with my success, wonder if anyone else will cotton on, just what it is I have done here.

Way to go Jim!!!!!  That is fantastic!

I wonder if we can get a magnesium tube and ram a carbon rod inside it and have a whole bunch of them?  you may have just taken this to an entire new level.

Nice work!

Bill

What you suggest might work, but you would need to use a tube just a little bit bigger, I would recommend the carbon electrode have a gauze wraped all around it, 1 turn should do, paper would do but it wouldnt last long in the damp earth, perhapse a dish cleaning cloth, like a chux, thin, porus and built tough to last, perhaps Jeanna might have a better idea.

What I will do is take a cell out of the ground and take it apart, pics will show exactly how I made it.

I drove into town and got a pkt of gal nails, the idea is to get more voltage with cells in series, to prove the concept first, then get amps and volts later.

I think i get it. You REMOVE the Toroid before attaching the Ignition Coil?

Yes. I do not have an ignition coil so I made a similar coil using a toroid. I suspect that if the extra toroid is replaced by the ignition coil that it is modeling then the circuit will still work. But, it may take some experimenting to get things working. Good luck.
