Step 4 Soldering the components together

The title says it all. Solder the componets together using this schematics below. Notice there is no relay. We tried a gun with a relay, put after a few shots, it nedded to be replaced. Since we are using a switch that cuts the battery on to make the circuit start charging, we need to solder a bare piece of wire to the switch on the circuit.

when i vas "studying" about coilguns for making one, i read something about if you conect a capacitor to a coil, it generates AC, and inverted voltages can damage the electrolythic capacitors, does it realy happen?, did you add something to avoid it?, is it just too small to be considered?
(yes, my ortography is realy bad, but i'm not native english speaker)

I dont now where you read that, but you dont need to add anything, the voltage is probably too small, and the capacitors are also very small.

thanks, i read it on the wiki

add a diode between coil and capacitor!!
