Hello, i'm high school student and i build simple capacitor discharge circuit for coilgun in multisim (it is from '15 Dangerously Mad Projects for the Evil Genius', Book by Simon Monk)
capacitors are charged when switch is connected to the wire at the top, and they are discharged through SCR when switch is connected to the wire at the bottom. zener diode is for voltage drop and LED is for check the state of charge.
i think i copied the circuit right but pressing the simulation button does not change anything on the oscilloscope and i can't find why. i think ground or diode cause some problem but i could't make it work...
sorry for the messy schematic and short English
