on video how to make pyrograph with ATX and toroid source

 I will show you How to Make Homemade Pyrograph with PC Source and Toroidal Inductor, in a very simple and easy way using toroids from computer sources.

We will take advantage of the switching of the source transistors that go to the primary of the transformer to generate our electromagnetic induction, exciting the secondary of the Toroidal transformer. As the secondary has thicker wires and few turns the secondary current will be huge much higher than the primary current, in this way it will be able to heat thick metals until they become red hot, our pyrograph can also be used as a homemade soldering iron, the idea it's the same.

List of Required Materials:

1 large ATX source inductor

3 meters of wire from a 3-in-1 radio transformer with multiple terminals, the thickest you can find in this transformer. If not, use fine copper, but not too fine. As I don't have a caliper, it's difficult to know the exact measurement in millimeters of the wire, so this is the tip I give you.

1 power supply atx 12 V good working

1 soldering iron

1 double shielded power cable

1 tin

1 piece of wire 4mm

1 electrical tape

1 piece of sandpaper

1 super glue
