Ultracaps tested for excess energy

I don't have $ to even spend on S&H right now so I'll use one of my toroids here, but this might help someone else. Here's search results from goldmine on toroids. Is one of these your toroid?

Paul:

A lot of us have used the 5 for 1$ toroid on your chart there, the 5th one down from the top.  That is what we call the Goldmine toroid.  1" od x 1/2" id x 1/2" thick.

I emailed goldmine and they don't know the specs on that toroid, so I just grabbed one in the lab that has some good permeability, about the same size as you guys describe. Then I made the JT with 26 gauge magnet wire, 11 turns. It's probably more difficult to use magnet wire since there's higher chance of the wires coming too close, but after winding it I made sure they wires were as far spread apart as possible to minimize capacitance.

All the parts are on the table now, 1N34A, 2N2222A, a variable high frequency capacitor, and 2.2Kohm R, and 10Kohm pot. I'll use a AA NiMH 2000mAH battery to charge the 650F UC.

Sounds like fun. It should be built in about 10 minutes.

The JT is working, but I'll post in the JT thread. The joule thief 101 thread, right?

@PAUL

Put it in the jule thief one.

Paul:

Good going with your JT.  You can post in that one or the regular JT topic...your choice.  Also, check out the JT diagrams topic where we put many of the schematics for the circuits that came up in the JT topic.  There are also page numbers there so you can read the posts associated with the particular schematic you are interested in.

I began work on my Lidmotor "Jeanna's Light" replication last night.  It is going to take a while but it will be worth it.
