This larger Joule Thief has a bifillar toroid core (90 turns). When resonating it can light neons and produce over 1,000 Volts. At one point the voltage reverses direction.

  • can you show exact circuit cos here you can not see anything

  • watch my latest video for circuit.. this is old video, watch all videos I made after this

  • Hi dodoshlodo:

    Great video, emjoyed, Thanks.

    Would you try to use this JT to light a bulb via cap?

    a string of 100 LEDs is possible?

    Thanks

  • ys I have powered a light via cap, but it doesnt light constantly. I can build up charge in cap and dump it into bulb.

    A string of leds does work too, u can light a string of christmas lights

  • I wished folks would take the time to do PDF's where people can follow alone with the VIDEO's

  • thats a good idea. I'll do that in future videos... When I get some free time of course

see all

  • Man I like what you are doing. I love the music, who is it? I know not everybody loved the music but I thought it was some of the best video accompanyment yet. Very good taste, great video. Keep up the good work. You are on to something.

  • You ever try illuminating a larger CFL with this thing, like maybe drive a 15 or 20 @ 12 watts? cool vid!

  • great vid but hate the music

    

  • I just watched your video again and recognized that your drawing says the 2N3055 has its Emitter on the case... i think that is wrong, it has its collector on the case. Am i right?

    Did you draw it wrong or did you also conected it the wrong way?

    Cheers...

  • Dude what's up with the ants running across the papar at 2:17 

  • you need a smoothing circuit with a few resistors and capacitors like in a probe for an osciliscope. so the high frequency currents dont waste your multimeters

  • I'm trying to reproduce your circuit. Could you post the exact diagram & parts list please? I would love to experiment with it. Thank you very much, I would share my investigation if interested.

  • you dident name all the parts in your schematic what are they the rectangle shape at top left and square thing at bottom right are they neons on its right to

  • @fdoca the body of the 2n3055 is ment to be the collector isent it your diaghram looks different and i really like to know what the square thing is in the circiut schematic

  • NICE WORK !

    : )
