  • cool, what kind of circuit did you use? can you give it to me?

  • @boryshacker It's a rather simple circuit the one found on most web site all parts and component are really not critical this joule thief cost me a big 0$ and work quite well too :P webpages.charter.net/dawill/tm­oranwms/Elec_JT.html

  • 1.5V x 0.250 = 0.375 Watts from your experiment.

    2.1V x 0.020 x 9 = 0.378

    Assumed 9 of 2.1V LEDs running at 20mils which says it's not saving energy but is a very efficient boost circuit. JTs run cool meaning very little loss to heat.

  • @TheAlabamaCajun Thanks for your comment and the time to calculate the power consumption. If i remember correct those white LED work at around 3~3.5 volts. But in any way this was only fun to build.

  • @TheAlabamaCajun leds run at 30ma at 3.5 volts. or so. and i think the joule theif pumps about 4-5V

  • the schematic diagram of this joule thief with 9 leds with capacitor

    thanks and more power

  • @jayson01982 Unfortunately the schematic is not my doing so i cannot post it i can simply redirect you to his website and for the way it work it's basically 9 LED in parallel with capacitor this was one of the first "high power" one that I've made so the new model have some improvement. I found out the LED work better if they are mount in series since they draw less amp but require higher voltage. "webpages.charter.net/dawill/t­moranwms/index.html#Proj"

  • @jayson01982 Check the last line of my previous reply the link is there between the " ". Have a nice day!

  • Nice!

    I am lazy though, I just got a flash circuit out of a disposable camera that i saw pirate88179 do, and it can actually light up more than 100 white leds (all I have at the moment) connected in series with a bridge rectifier, and they light up pretty bright and runs down an AA in about an hour then a couple of hours dimly. The coil gives out a high pitch sound and the transistor on those circuits gets kinda hot, should maybe put in a heatsink like you. I haven't measured the amp draw.

  • @MasterTxJ ^^ indeed Those small circuit draw a lots of amp. You can Run 100 led with a circuit that can probably draw less amp but you'll need to wind your core. Ive made another one that run 12 High intensity Yellow LED from 1.5~5v I have a pot so i can adjust the max voltage and the circuit draw about 50~100 mA. If you connect your LED in serie you'll need less amp but more voltage if you connect them in paralel you'll need more amp but less voltage experiment :P

  • @bakupcpu Yea I should try winding my own cores, thanks. Right now I am trying to build a Slayer exciter by user Gbluer and I am going to power it with an earth battery the same as the one Lasersaber made. He got about 1,6 V@ 100mA when he used wires aligned with the earth magnetic field (check his vids). Imagen the possibilities of that. In one of his vids he sais that he has powered a small motor for about a year with it, makes one wonder if it's just galvanic forces at play.

  • @MasterTxJ lol indeed Your right on that one never tried an earth battery maybe ill try one this summer O.o.

  • @bakupcpu

    can you send me the schematic diagram plssss..

  • @jayson01982 There's no magic in there its a basic joule thief circuit with a little more power. Its not my design so ill simply direct you to the web site!

  • Light every room of your house with one Joule Thief, multiple secondaries: v=BztnQB2sgg0

    Joule Thief Lightning Maker, huge white sparks, uses one spark to pulse car coil to create huge spark, he refers to Jeanna and Kooler's work: v=jGJKtYbGLw4

    Lidmotor is doing wireless (12v) JT = 600V electricity and one wire (1.5v) electricity). v=ka-YSuBlJxY

    We've also created a JT with completely independent secondary coil on overunity forum. Uses a PNP and a NPN..

  • Good work, and thanks.... "Super Joule Thief" is actually a different circuit with a single wind coil.  v=EzlMHlnK2DM

  • Well i gave it the name Super because i light up 9 LED but you can wind it with single or dual coil if you want 2 transistor is needed for the single coil version tho ^^ but they all work well!

  • really nice
