Joule Thief

[xee2]

Another untested design. This is simpler and should work better. I do not have an ignition coil to test it with yet. The wire wrapped around the ignition coil acts as the base coil for the JT and the ignition coil primary acts as the collector coil for the JT. The ignition coil secondary acts as the JT pickup coil.

That looks like a cool design.  Do you really think it will work?  It looks so easy....even I could make this one.  Very nice.

i have an ign coil but mine is a steel case ... 

i do have some lawn mower coils ...    a bunch in fact ... i dont see why i cant pop a relay coil on them tho and protect the sw .. and force it out that coil  ....  plus those give 1 hell of a smaker... lol

yikes ...

i might just have a fly back core that would work well there lol but i bet i can bombard the lamanted iron core ... 

ist...

im just packing anywhy ... so as i find stuff i whip it up as im down sizeing my junk any how 

there is no reason you could not do it mechanical .. and build it from junk motors all you would need to do is find 4 old lawn mower motors you could just use it as it is designed and charge bat caps fast all you pay for is the engery to move the magnet .. past the coil .. and btw when you spin it faster ... the easyer it gets .. less drag it would be a GOOD RING OF FIRE TO GO ALONG WITH MY SELF CHARGEING SELF RUNNING PULSE MOTOR

just for some grunt  the thing is spinning any way .... why not tap the mechinical  side of it too with another ou generator from 100 + years ago .... lol

Do you really think it will work? 

I think it should at least light up a neon bulb. I think it will work better than Fuji board. But, then again, it may not work at all.

@xee2

When I put a bigger resistor it does not work.
When it has the right resistor, the resistor gets extremely hot.
I ordered an mje13009 transistor and resistros with 5w strenght.
Lets see what happens.

@resonanceman

This specific flyback configuration has 5b-5c winding. When I put a 22r on the circuit and the circuit is connected to a spiral fluoro, the spiral fluoro lights for a few seconds before the resistor and the transistor get too hot to work.

I stored your explanation and the photos of your flyback configuration.
I will eventually will make the experiment.

@jeanna

This flyback coil I composed with what was left of the flyback circuit when is cold, the neon bulb lights with just one cable from the pickup coil. It is an excellent joule thief coil, the only thing needed is a good transistor that can stand the amperage that heats the circuit.
