    Any chance of you posting the directions on how to make this?

    i love joule theif. nice way to put it. what gauge of wire are you using for the coil? im using a really small gauge, and its hard to solder with. its enamled transformer wire, about 40 turns around. i guess i dont need that many if your getting such good results.

    i think i used .35 gauge copper insulated, it is hard to solder with , thats why i used such large beads of solder .. you only need about 8-13 turns and its best to use a uncoated toroid
