Step 9Wiring the Box
This step describes the process of connecting the (+) copper plate and the (-) steel plate to the power supply.
Drill - Drill a hole (of the same diameter as the wire from the power supply) into the side of the box. Put the wire through the hole, strip an inch and a half off the end, and separate the two different polarity wires. Using a multimeter, determine and mark which wire is the positive and which is the negative.
Solder - Solder the two wires from the steel plate to the negative wire from the power supply, and solder the two wires from the copper sheet to the positive wire from the power supply. Cover the soldered bits with electrical tape to prevent shorting.
Tape - Tape everything to the underside of the steel plate, or (if you made the optional square to organize the wires) tape everything to the bottom of the acrylic. Gaffers tape is always a good choice.
Test - Using an LED, test the board to make sure that it is wired correctly and working.
