Building on the last post's electrode plans, after extensive testing, I'm going to make a "cell" out of the carbon electrodes. Each row of electrodes will be joined together by a soldered wire, and there will be several rows, alternating between (-) and (+).
I'm still looking for a new bootleg flashback arrestor...the last one made from a medicine pill bottle had unforeseen leaks.
Also, during the long hiatus, I had beefed up the capacitor bank charger/discharger. Now it blows half-centimeter diameter holes in aluminum foil and blasts little craters (deep enough to see zinc) in pennies. I may or may not post pictures of those.
I know how confusing this is, so pics in a few!
