Step 1: Parts List
- Metal Clip (either with or without suction cup)
- heat shrink
- header pins
- red and black wire
- Panel mount power jack
- wall wort with plug that matches your power jack, one with adjustable voltage like the one pictured would be best
Step 2: Assemble the Parts
Step two: Break off two pins from the breakaway header and separate the two pins, making two single pins. Cut two pieces of heat shrink tubing and thread one over each of the wires. Solder a pin to each of the wires, since the pins usually have a plastic ring on them, put the opposite end of the pin in an alligator clip to absorb the excess heat so that the plastic doesn't just melt off. Be mindful not to overheat the pin and melt the plastic ring.
Step three: Thread the wires through the hole in the metal clip. It may be necessary to make the hole in the clip larger to accommodate the power jack, it may also be necessary to bend the clip outward in order for the power plug to clear the other side of the clasp. It can be placed in either direction but placing the plug so that it faces up and fully exposed lessens the likelihood that you might accidentally short the contacts. Add the washer and nut and tighten securely.
