My Capacitor Bank
You'll see before I glued them in, as I was counter-sinking holes for them to sit in. So far I have MOST of them wired together, in parallel, but I only hooked up the larger ones until I get all the "bugs" wrinkled out.
I'm also using a relay circuit to switch the output from the capacitors (so I don't fry myself while they're charging). I have it set up with a 2-way toggle switch, so when I hold the switch to the right, it charges my capacitors, and when I flip it to the left, it triggers the solenoid, and I can then discharge the capacitors however I want.
Right now I'm in the process of finding the right power supply, as I have both the relay, and the capacitors charging off the same 12V (1A) wallwart, but it's not enough juice for what I want. Enough to burn little holes in tin foil with the sparks, but It's just simply not dangerous enough for me!
Me and nachomahma are working out something so an update will ensue!
