Tristan decided to build a nifty electrolytic-powered disc launcher using “eBay capacitors and some charging components.” Video demonstration after the jump.
I set out to design a more portable, electrolytic-powered, coilgun. Unlike EMP-2A which used a capacitor that weighed around 100 lbs and required nearly 10,000V to charge it, this new project will be portable and easier/safer to control
