I haven't tried it on me yet! <sigh> Too busy tinkering with other details of the alleged protocol I'm getting ready to do. However, I did re-engineer it slightly. I disassembled the coil and pulled about 20 turns off of it. That actually killed the pulse- strength a lot. The tube flash was noticably shorter however. I also shortened the wire from the unit to the coil by a couple of feet at the same time. Next I took it apart and re-worked the capacitor mod. I had put in a single 270 uF 450 volt capacitor. Seeing the suggestions from others here to use upwards of 600 uF, I took it out and reworked things so I could fit 2 of them in the available space, for a total of 540 uF. The small #8 flat washer now jumps a good foot and a half, and a 1/4" flat washer jumps a few inches. The 1/8" fender washer hardly moves at all, still. This *is* more powerful than I had originally, and I deem it adequate to use for now. In answer to your other message on this thread, I'd suggest to you that the 200 volt capacitor is beyond borderline and likely to fail -- perhaps spectacularly! I don't know how much of a safety margin they build in, but keep in mind that the circuit is a voltage doubler, and charges the cap up to at least 240 volts or so. I bought mine from Digi-Key, www.digikey.com ... They were $5.40 apiece and part # P11787-ND. You might revisit my part selection, because I think you could fit a single 600 uF (or even higher) part in the same space. (Hmmm... I should think about that.) Go to their main page and type electrolytic capacitor in their Parts Search window. Click on the resulting link, and you'll be at a fancy part selector form which you can use to browse their stock. Unfortunately you can't input a *range* of voltage or capacitance, but with enough tinkering you can find something suitable. Their P7420-ND, 680 uF, 400 V, 35mm dia x 50 long -- looks like a possibility. I'm talking about laying it on its side. The 35 mm dia fits somewhat closely between the top of the components and the roof of the case, while the length fits between the control pot and the back side of the reflector. This one might be ideal: # P11798-ND, 820 uF, 350 V, 35 mm dia x 45 mm. Comfortable margin on voltage, an easier fit end-wise, high-ish temp range. http://dkc3.digikey.com/PDF/T033/0705.pdf I'm not comfortable cutting it as close as a 250 V part. These are better. I used 14 gauge solid wire to connect the caps snap-in terminals to the board. They're a good company. I've bought from them several times in the past. Good luck, Robb, and let me know how it goes.
