Completely Portable single stage, 100 joule(ELECTRICAL ENERGY), bolt action, 6 round mag soon to be dual stage, 200 joule(again ELECTRICAL ENERGY) I've had a few ask how I built this gun so rather than answer everyone's questions individually I'll just answer it here. I started with a 12 volt SLA (sealed lead acid) battery that I found online somewhere. That powers a power inverter that you would normally use in a car to get 120 volts ac. That powers a voltage multiplier ( google it to find out what that is if you don't know that's how I found out). And that puts out the 385 to 400 volts to charge the caps. The capacitor bank is made of 3 electrolytic Caps that have a 450 v. capacity rating and I believe are 470uF each. The box in between the barrel and PVC pipe are 2 solid state relays wired in parallel to fire the coil. There is another solid state relay that turns the charging on and off. the Coil is made from 2 strands of 22awg magnet wire( it was what i had next time I think I'll use 1 strand of 18awg). From what I've found so far the size of the coil depends on the size of the bullet and cap bank. Mine is a little bit longer than the bullet and about 1" in diameter. I don't think mine is quiet right but I'm still working on it. There is also 4 hi cap diodes wire anti-parallel to the coil. This protects the caps and charger from the reverse voltage created when power is removed from the coil. So the Gun is basically controlled by 4 switches. The red switch is the ...
