Hey nice to see you again guys! Now I'm back with another instructable. I shall teach you how to make a diy joule thief. This is one of the easiest way to make a joule thief and the most powerful one. For those who don't know what a joule thief is, it's a small circuit that is capable of powering an LED from an old 1.5v cell.
So, let's begin!!!
To make this project, you'll need:
A toroid bead
2N3904 transistor or any equivalent one
