I am currently interested in getting as large as a capacitor as possible and I would like to know what devices I should be looking in to find high-capacitance and high-voltage capacitors. as of right now, the best capacitors I haver are 2 200V 330uF camera flash capacitors and a 6800 uF capacitor rated at 35 V that I randomly found out of a particularly tempermental Inkjet printer.
My goal for all of these capacitors is to hook them up in parallel, charge them with as many 9V batteries as possible, and try to melt a hole through a dime from the massive discharge of the capacitors. if at all possible, I would like to exceed 1 Farad at at least 50 V.
anyway, I need to generate as many sparks as possible, and I would need to get my capacitors from a cheap source (i.e. monitors at thrift stores)
