Simple Joule Thief Circuit Diagram. You won t get much current from it but you can get eno. The above circuit is joule thief circuit using an ordinary step down transformer with centre tap.
8x more output from a simple joule thief circuit while developing this overunity circuit he was amazed to see an 8 fold or 8x improvement in the power output which simply indicated an 8 times more output being produced by his circuit compared to the input supply power. The conventional joule thief wastes about half of the power so if you can use the supply voltage directly without the joule thief it can double the battery life. In effect the 4 legged ic replaces the clunky toroid.
A joule thief takes a low dc voltage and boosts it up to a higher voltage.
This is a very interesting circuit it will drive 3 6 volt led from a single 1 5 volt cell. The explanation of what a joule is can be found on the wikipedia page here. The quickest explanation i can think of is that a joule is a form of energy that in the way we use it can be. The circuit diagram in the first picture above shows a 470k ohm resistor in series with a 2 volt solar cell and connected into the joule thief control circuit effectively in parallel with the on board trimmer potentiometer.
