Hmm. I thought it was E=1/2C*V^2, where E=energy in joules, C=capacitance in Farads, and V=volts...

U = (Q^2)/2Cwhere U is energy(joules), Q is charge (coulombs) and C is the capacitance (farad)

Thats the sound of aluminum washers in flight. Some say they sound like UFO's.

that launch makes a really eerie sound

Q=CV

If you know the voltage and the capacitance, you can find how many coulombs of charge you're storing.

The resistor slows down the charging of the capacitors and limits the current through the power supply.

what would happen if you stood on the disc while doing a test fire?

Pretty impressive device. I was wondering have you considered modifying it to use a relay hooked up to a good few feet of wire and a momentary on switch as a wired-remote of sorts? I'm thinking that it might be a shade safer and a lot more convenient for filming the device and you wouldn't have to use a longer cord for the launch pad.

You should mention it's a hard drive platter.Whats the resistor for? |
