Our friend Daniel Eindhoven from Megavolts found a great price on some huge used capacitors. These capacitors normally cost around $90 each, Daniel was able to pick them up for around $2 a piece! That is one hell of a huge capacitor bank on a nice budget. He also designed an interesting mechanism to tie the batteries together. Instead of using wire or busbars he designed a few laser cut sheets of metal and PCB. The PCB is acting as an insulator between the two metal sheet conductors. So the next question is how does one switch that type of power? The light switch at Home Depot is not going to cut it. “My new capacitor bank is finished! This bank holds 38x 4700uF and 2x 3300uF capacitors of 350V in parallel (total 0,1852 Farad). It can hold a maximum energy of about 11344 Joule. Specifications: Capacitance: 185200uF

Nice cap bank

nice. maybe i may suggest one little improvement:
your switch bounces 1 or 2 times. this eliminates steady current flow und your current flow through the coil is interrupted badly. if you can fix it, you’ll have much better effects and efficiency. maybe you can built your switch more like a regular connector, with a female and a male part.

Actually wouldn’t a wide flat contact work better than the pointed one?
You’d get less deterioration at the point of contact.

This guy builds some great stuff, but he really has to work on the music he puts in his videos.

Yes Chris… Maybe you could put the point on some rubber or spring backing that will absorb the punch…

The bounce really is a problem, a lot of energy is wasted by this and the concept of a mechanical switch. I do get good suggestions to prevent the bouncing action, and I’ve come up with a few good solutions as well.
But I think I’m going to leave it and try the hockey puck thyristor. I didn’t try them before because I wasn’t sure they could handle these currents. Now I’m pretty convinced they can.

Thats one huge cap bank. Might be a better idea to series together a few caps to get more voltage as that gives you higher peak current and that kind of mechanical switch works better at higher voltages.

ARGH! It just breaks my heart seeing people spend huge sums of money and time building wonderfully pretty pulsed power gear that won’t work.
A _mechanical_ pulsed power switch? Are you serious? May I suggest you do a bit more reading and grasping more theory before you waste any more time and money.
And after assembling all that energy in a nice low-inductance bank, you have all of 350 volts to work with? Why even worry about keeping the inductance low, it’s not as if you’re ever going to achieve fast rise times or significantly high currents.
Man. When you do that reading, maybe start with Ohm’s Law.
