Ultracaps tested for excess energy

[gadgetmall]

Thanks for the info. That should be enough to build it, except one thing. In your older circuit I have written down 1000pF across the 2K resistor. That's changed to 68pF? The 2K resistor (now 2.2K) is the one that goes directly to the 2N2222 base.

Thanks,
Paul

There is no difference in my circuit using 2 or 2.2 k and you will have to play with the capacitors to find the one that matches your wire ,transistor and toroid . I have a lot of 2n2222a transistors and each one is different charistics . Also the toroid might be different as well . Weather 2 k or 2.2 the pot will adjust it out the same . Yes i change it cause i got a bag of 68 pf and a bag of 2.2k. As soon as i recieve a populated board i will update the one on my thread in the prize section to match what the final design looks like . for now its to save the spot ! It works as posted if you use the goldmine toroid

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?

g6683 .. ISt has 500 of them waiting here  !! IST !! I need to get these to ya before Christmas please . Save some of that Green stuff money 
Hey if you order from gold mine dont forget to order your self a 5 dollar grab bag . they contain 3 ,4hundre dollars worth of electronics parts ,coils leds , speakers ,switches ,inductors ,connectors ,scrs, supercaps,micro motors and a whole lot more ! .its worth it

Hey Albert,

Have you tried toroids from https://www.amidoncorp.com ?  I've bought zillions of theirs in the past. Nothing special, but prices seemed good to me back int the days. As for special cores, I highly recommend Metglas & Hitachi, but not sure how they work out for cop>1. J.Naudin said his MEG was a lot more efficient with a Metglas core.

? nope .The Best ones as are determined for Jt research are from MICROMETALS  or magnatics www.mag-inc.com It has been determined thru 1000 pages  that the best torroids are high perm and low flux , At least this is what i am useing . Some toroids dont work at all for transfering to a secondary or starting a transistor in a jt . the BLUE ones SUCK . most out od an old power supply are good . I tor up 10 old computer power supplies and took all the  trorrois out of em . they have 3/4 to one in them also . they work nice. but 5 /1 dollars ones are considered by the Jt group STANDARD  . this is so we all can be on the same page when using toroids . Just like the Jeanna light torrid . I had some that looked like them with gray coating but they Dont work at all . I just got 4 free ones from mag-inc .and a few bigger 5 inch ones . you can order free samples every week up to 10 each  of 7 items(torroids)the biggest i got was the biggest they have 144 MM !!! all i have to do was pay shipping . They are very powerful toroids . I got SIX in the last free sample order for 11.95 total . these toroids would have cost hundreds of dollars as the price of the 144 mm is 99 dollars if you buy 158  minimum .The best i have ever wound . Light up cfl bulbs with less than 100 turns off the secondary and only 9 turns on a primary .. please check out joule thief 101 on the first page for an example of a good toroid and the winding by Xee2.
The BIG ring is for something VERY special IST HAS to share with me ! SUPER TPU
