Joule Thief

[Cherryman]

There is no transformer, only a 1.5" toroid x2 with around 120-140 turns on secondary, A used is a 2n3055 which I considor a good choice, and anyway I have lit a 4 watt 240v fluoro also a 5 watt cfl with components pulled out of it !  But they dony light any where as good a this 20x LED bulb, its very bright, I only need possibly 1 of these lights per room, I like the 20x LED bulb because I can just put it in my lamp and plug into my JT-power supply and be off the grid (lights only) at this stage !

My total volts on 2x AA which has around 2.5-3v , I get around 850-1050v, 3x AA = around 1100-1200v,
I will stick to 2x AA, maby add more more amps and then my light will last up to 2 weeks with more AA's
That means I only have to charge my box every 2 weeks !
Our electricity is going up 70% over next 1-3 years !!!
So best to light my house for free off the greedy grid!

Congratulations!

You made a perfect example of how the open source research here on this forum and the internet can result in a usable device!


Good job!

Mankind can only take the smallest of steps. The members that take the largest steps are misunderstood or condemned for their efforts.
After 895 pages a transformer is missing? But a toroid is in place? This is the same circuit since page 1.

Retard is good term. That means a retry of tardiness. Obviously the shoelaces are tied together in this leg of the race. It is a fast race of running harder and faster, not better.

But the answer has come back around. So therefor if someone is stealing your work of copying it over and over then the original inventor can not be found. Kind of like a safety feature. Spread it out so thin that those who oppose have no trail.
The noobs get a chance to experience for the first time the exhultation of getting results of seeing a pattern happen over and over again by others who had the grace and mercy of the fore builders. I don't recall getting any bad vibes from copying Telsa's patents. But look at the attention it garnered? For me for a short time but a reamplification of Tesla's work into the history books and again.

Everyone should get the opportunity to travel down this path on their own reconnaissance.

here is one of my LATEST JT'S ITS HISSING AND SINGING ... and it hurts if you touch it ... 

runs on a DEAD 12VOLT...

Hi Freepow very bright led bulb interesting about that circuit. With one toroid is not enough why did you use two? I had build one with a 1" on slayer circuit and it gives high voltage too.
Thanks

Hello  Guruji,  I too have lit a number of LED's on one toroid as well, but for these particular-
20xLED light-bulb I need high volts, they have some components inside the bulb, they are designed for Australian mains power, I can power it with one toroid and 1xAA, but the light is then not really that bright, but adding 2 toroids and having 2xAA's it really lights very bright all 20 LED's, so I can then have a decent light for each room !
