This is the prototype of my curent Coilgun design. it has an on/off switch, a charge switch ( for wich im using an push button that can lock), and an trigger wich, in the real disign. activates an thyristor. all that is powered by 10 9v block batteries. i know there are way better methods but im kinda new in the buisness and thats the best i know. but still i'm asking if any of you pros can give me an advice to improve this design. thanks and sorry for any mistake i did english isnt my first language.
