Reverse Joule Thief

This is the reverse joule thief I found on YouTube. Supposedly it works better. I wrote this tutorial because I wanted to find a freeway to build the circuit

One old PC power supply, any will do fine.

Okay. Now you want to get the power supply out of the PC box by unscrewing four screws that hold the PC Power supply in place.

Now that you've got the power supply out of the PC, find the side with the four screws and unscrew them.
Then open the two pieces carefully.

Let's began by extracting the toroid bead from the power supply with a soldering iron. Afterwards take off a few copper wires and leave 2 on in order for the Reverse Joule Thief to work.

Looking through the circuit board to find the resistor,1K, using the soldering iron again we will extract the resistor,1K, for our Reverse Joule Thief.

Again we look through the circuit board to find a transistor, no matter which one,  and use the soldering iron to get it out of the circuit board.

Now it is time to use the schematic I found on YouTube to build the circuit.
After you are finished, you will have the Reverse Joule Thief circuit ready to use with a 1.5v AA battery free of cost.
