“This my first build for my Gauss Gun project. I have wanted to do this for a long time but I never had any beefy SCR’s or HV capacitors to complete the project. Suffice it to say I improvised and used some high current relays and decided on a more complex 3 stage coil design since without the massive current burst provided by the capacitor it would be difficult to gain significant speed with fewer stages.”
