Build a Real Ray Gun at Home

Step 4 Wiring the Charging Circuits


For the raygun to work, all of the capacitors must be charged. The indicator light with the capacitor on the board that it was left in should blink almost immediately when turned on. Solder in switches to switch between charging either of the two rows of capacitors in the capacitor bank with the other board. Refer back to step 2 for a picture. The two different places the switch should switch to are labeled "Switch 1" and "Switch 2."

Remember, polarity is very important. So make sure the positive from the charging circuit is connected to the positive on the capacitors and vice versa.

NOTE: You will need to wire switches so that before switching between charging ROW 1 and ROW 2 the row that you were charging is DISCONNECTED otherwise there will be a big spark. Use HEAVY DUTY switches also. Touching the capacitor terminals at any time is DANGEROUS!
