Anyone designed/built one of these?
Just wondering about the metallurgy issues and how current/voltage affects them.
I'm having one heck of a time trying to locate large capacity low ESR capacitors. Will a higher voltage and lower capacity be a replacement for high capacitance, low voltage? (by E=0.5C*V*V) Will I just kill the caps or get uncontrollable sputtering if I do that?
What kind of electrodes are good? Will copper spike electrodes be sufficient or will it 'stick' to the work area? Where would one get the tin strips to weld on batteries?
