If you liked that, you'll love this: http://www.popsci.com/popsci/science/article/0,12543,490445,00.html I wouldn't have believed it possible, it's truly an amazing practical application of theory. I wish I had the link to the first site that I saw this on. That guy used some serious banks of capacitors and could shrink a US quarter (24.26mm) to be smaller than a dime(17.91mm). He was working on doubling the power. Apparently it makes an incredibly loud noise too when the coil evaporates. Combining that with the light show makes it the perfect big boys toy for entertaining guests at a barbecue. Don't you all think so too? ;-) michael brown (I used to want a big Tesla coil, but now I'd much rather have one of these) -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
