Dept., Univ. of Notre Dame, Notre Dame, IN Lines: 16 Summary: I built one but never got as good effects I built a Tesla Coil when I was in High School in the early 70's. I used the popular electronics "big-tc" plans but for some reason I never got the kind of effects you people have described. My system used about 5 feet of carpet tubing for the secondary (heavy laquered cardboard about 4-5" around). There were 3 glass plate capacitors about 1.5 feet square wired in parallel, a spark gap and primary with about 10-12 turns of heavy wire. The primary was driven by a 12kv neon sign transformer. The best I ever got out of it was a 6-8 inch discharge (to a nail on a broomstick). Did I do something wrong or is my coil too small? Regarding weapons...I heard something bantered about on CNN awhile back about generating "cold implosions" by projecting "scalers". The equipment was supposed to be based on some of Tesla's work. Any idea what they are talking about. Greg Corson
