I recently had to purchase a roll of Aluminum Chimney Tape to fix a hot water heater exhaust. All in all, I needed about a foot or so of tape, but the smallest roll I could find anywhere was a ridiculous 95 feet.
So I've made a few quick-n-dirty heat sinks for some low-watt chipamps. I RF shielded an enclosure for an audio device. Could probably do that to a couple of guitars, etc. I spose I could make some awful circuit boards by sticking it to pressboard, and cutting out some traces with an exacto-type knife. Any other uses for this?
I could grab some wax paper and make some crude capacitors. With a little more work I could even make them variable capacitors. Anyone have a surface-area-to-farad scale or conversion?
