I've been able to do some work on the cap bank, the fotos you see below are run off a 0.188F cap bank at 19V, which makes a total energy of 33.934J
However in the fotos I took thin strands of copper wire to short the bank.
To trigger the short, a relay was used.
The finished thing will be enclosed in a case and will have safeguards.
cheers!
