Joule Thief

[j037m]

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!

bro freepow can i ask whats the wire you use on primary and secondary also is it two toroid connected together or not been trying to do same but no luck...

@ jo37m

I only used  2,8,125 turns I think, and the actuall volts are higher than I posted back then, on my scope it read around 1259 volts with 2xAA used ones, I am not going to use 2xAA's, I am going to use a 400F supercap that I recently bought.

This is the major project for our small house, I have a large hinged plastic box that I will have all my joulethiefs in and a small box on top with 2 analogue meters to read the solar panel, and each supercap will charge in 6 minutes and light will last around 2-3 hours, meaning turn them on at 7:00pm and turn off at
around 9:30-10:00pm and go to bed.
Thats my major project, light in each room, will post this project for all to see when finished.

only a 1.5" toroid x2  <<< is this mean that you use two toroid combine also can i ask what size of wire bro on primary and secondary thanks for reply cant wait to make same like your project

@ j037m

I used solid hook up wire(insulated) for the primarys thicker than the secondary,
the secondary is about 0.6mm diameter I think, the 2 toroids are on top of each other and electrical tape wrapped around to keep them together.

for the jt ers

i closed the loop and made a self runner

this is no joke

it uses an aa battery  but i made a simple charger for it .. it uses 3 2n2222a's 1 as a jt  other 2 are rf recharge can be run constant with any jt or can be placed on a switch .. 

its hot s**t works great every time as per the design ...it charges super fast

here is a picture of the unit

osiris

it is a directional  rf single loop transmiting antenna aimed to the input of the coil ..  there is no pos connection  on the rf recharge ..  it must transmit rf via eather to make the connection ..
like i said works great everytime


i have confirmed it is rf doing the magic just as i have explained
