Back in February, I started creating this design to have a "night light" or an under the cabinet light. I then thought, I already have custom under-the-cabinet lighting. Why should I change what lighting I already have, and it's only 6 months old. So then I decided to keep the design, and just put it under the shelves above my desk. Which would make it into a night light because my desk happens to be in my bedroom. So technically, it isn't under-the-cabinet.
-18 gauge wire
-Several resistors (matching the number of LEDs)
-a switch (optional)
-Anything else that is mentioned

Viewers Note: I ran out of resistors. I only have half of my stuff lite, so understand that. I also didn't solder...I ran out of solder. Thanks!
Step 1: Find a Power Supply
No pics of mine. You should find an AC to DC power supply. The input should be 120vAC and the output should be around 9vDC to 15vDC. You should be willing to destroy it. Cut the end that is 2 inches or so from the small cylinder. Then strip the wires. The wire (dotted or straight on) is the positive wire. Connect the + end to your switch. Solder if needed.
