That's what I'm talking about, the good old(new) days and big nut sacks. Not those pseudo pussycats calling you a fed because they can't handle the pressure! That's the real deal kids.

First of all, im running a 6uf 10kV cap bank with regular rg58 coax. The coax is just rated for 2kV/5kv peak but it's holding up great so far, 8months a lot of discharges, no issues. It's polyethylene between the inner and outer conductor and according to the Internet the dielectric break down strength is at least 20kV/mm. The insulation is 3mm thick. So in theory 60kV but officially it's rated much lower. As I said it's handling short 10kV pulses with no problem. I'm wondering if 20kV would be fine two. Thinking about ordering bigger caps (20kV). Do you think it will be fine, at least according to the break down strength of the PE it should be, still worried because the cable is rated much lower. So would you guys try it?

Secondly, any better way to measure high frequency DC output more precisely? Currently it's a HV DC flyback, diodes and charging resistors, 2 small caps for smoothing the wave a bit and then the main cap bank. The voltage divider is connected to the main cap, 33V on the display of the multimeter should be 10kV in reality but I always have the feeling, it's close but not a 100% accurate.

Has anyone ever attempted to design one of them or even managed to build one successfully? Just for those who don't know EFI's are advanced compared to EBW, they accelerate a flyer to 5km/s without using a primary. Just pure electrical energy.

Hey guys wanted to ask if you made similar experience. Year's ago when I was pretty new to building capacitor banks and getting into pulsed power and exploding wires etc I accidentally touched a 0.22uf 2kV cap and I was quite shocked by what happened. It didn't hurt at all. All my muscles just locked up and my view went totally black. A second later I was back and at first I didn't realized what happened. I knew I got shocked while rewiring stuff but I didn't know why and by what. I checked the main cap bank, all empty, zero volts ( I knew because I had it shorted for safety before rewiring stuff) I checked the transformer and the variac and the plug to mains voltage. Everything was dead, unplugged and safe. It took me another second to realize ohh shit that 0.22uf 2kV cap had voltage left. It happened because I was stupid, it was such a small capacitor and such low capacity and joules. I didn't took it seriously enough. Was like ohh that little thing ain't lethal. Yeah I was stupid. Since then I never had another accident and I'm glad it wasn't the 360uf 5.6kV cap bank. I guess if it was I couldn't make this post. Anyone else ever made a similar experience? No pain but pretty much just shut me down.

Guys it's getting confusing as hell especially for people outside US. So what is the legal definition for doing explosives in USA? Dugan got arrested, a lot of people saying doing energetics is legal as long as you not engage in business etc. AI is saying the opposite but there's also an very old video online of Darian Ballard saying the ATF visited him once because of energetics etc. but it seems it went well for him. So honestly I don't get it. So maybe here is someone with a law degree or someone who knows 100%. What is legal and what is Illegal in your country as far as energetics go?
