Have any spare pinball coils around?

I wouldn't sacrifice a working one, and I don't have any anyway.

SirPeale:
I can't believe I can't find a broken motor in my house anywhere.  I've got to be able to find a coil on some broken piece of equipment around here or something.

A new joule thief was posted on Make earlier.

This one uses two transistors instead of the one in other diagrams I've seen, as well as a couple caps.

SirPeale:
I got my joule thief working.  I found a small transformer on a TV chassis and unwound the magnet wire from that.  Wrapped it around a toroid from a scrapped motherboard.  Then proceeded to assemble the circuit.

Total cost: .79 for the SN4401 from Radio Shack.  I might get that to zero if I could scavenge a compatible part from something.  I'll have to start looking in power supplies, I think that's the best place to find them.

I'm going to put this one in my computer case.  Always wanted a blue HD LED indicator in this case.

I'm wondering if I can use this circuit, and instead of a battery lighting an LED if you could put a solar cell in place of the battery, and a rechargeable battery in place of the LED (with a blocking diode, of course).

That's going to take a lot of work if you want to light a camper with that  :P
