No, I haven't but, I ran across something very interesting, at least to me, but I am Ignorant to allot of things in this world. A SUPER CAP. I watched a guy last week charge a roll of clx wire on a spool, then shoot sparks from the ends when he shorted the wire at the end. I never much thought about a large spool of wire acting as a capacitor, but all the ingredients are there. He was telling me that you should always short the wires on a spool before working with it as it can store static electricity and it can get rather high over time, if the conditions are correct. Hum, that ought to run a clock for sometime?
