Build a USB powered work light with only a string of christmas lights, a USB cable, nail clippers (or a wire stripper) and something nearby to hold it up
Step 1: Get POWER!
Take a simple USB cable, I used a A-B type cord. Clip off one end, if using a A-B cord, clip off the B end. Strip off the main insulation and the inner insulation on the black and red wires. You now have a 5v 100mA DC power supply that will work in any powered USB port.
