Joule Thief

[Pirate88179]

Hi Pirate, thank you very much for the pep talk, those are actually my feelings as well, leds are much more benign to nature. Though just for my knowledge sake, i know you replicated a jeanna light, it was a good video you made, what gauge base and collector did you use and secondary wire gauge. I fired mine up and could not light any fluoro's, i then reduced the 26 gauge base to 4T and reduced the collector to 6T and still no go, though i did light up my 30 string of christmas leds to probably half brightness. Your help appreciated, thanks.
peace love light

Thanks.

I am pasting this here from my video description because I could not remember exactly what I had used:

"This is my replication of Lidmotor's Jeanna Light using Jeanna's large  toroid Joule thief design and Lidmotor's circuit.  This circuit puts out  between 1,200-2,000 volts!  I do not have an exact measurement yet. (I  am afraid of frying my measuring equipment!) This uses two 3-3/8"OD  ferrite toroids, TIP 3055 transistor, 20 ohm rheostat, 15 turn variable  1k resistor, and 28 ga. magnet wire for the secondary and pick-up coils.   I used solid copper 22 ga. wire for the primary.  The cfl is a 40 watt  equivalent rated at 9 watts. In the video, I am running from a 1.4 volt  C cell but, I have run this on an AAA and an AA and a D cell as well  using my magnetic universal battery holder idea. For more information,  go to overunity.com in the joule thief topics area.  This is a lot of  light and it lasts a long time and you can use dead batteries that  others would have tossed out to power this.  More to come using this  circuit.  Please use caution if replicating this, or any other high  voltage output circuit.  If you don't know what you are doing, get  someone who does to help you or don't do it.

Thank you for watching."

I hope this helps.  In the video I believe I give the number of turns on each...I think.

***EDIT***

Tuning is very important on this circuit, or at least it was for me.  The difference of not being on, to being on, to being very bright and then to being off was not a lot of movement on my vr at all.  I also ended up placing a very strong neo on the toroid to raise the frequency high enough that I could not hear that squeal...somewhere above 20,000 Hz.

Did anyone lit a neon bulb in AC current with a JT ?
Any response there?

Yes, Xee2 did many pages back, I do not recall where exactly.

At first he had only one side of the neo lit but then had both side glowing nicely.

Hi folks, Hi pirate, thanks for the info. maybe i need to try a little thicker wire for the primary coils, will see. Hi kooler, thanks for your input, though i hooked up that other diode and still the same. Are you sure your led off the transistors collector is oriented as you show in the video, at any rate, I'm only getting half brightness. Also, you said your base resistance is at around 48kohms and mine has to be 150 ohms just light the led, any ideas what i may be doing different from your circuit. Thanks.
