It's the day before Valentine's. You had forgotten that fact until now, and have nothing for your girl/boyfriend / spouse. Realizing you error, you jump to your workspace to clear your head and find a solution.
Surveying the table, you find a burnt out 20 amp, a yellow LED, 2 feet of black and red wire, 2 button cell batteries, a small magnet, sandpaper, a drill, and a soldering iron (with solder of course). Go to it MacGyver.
So here's what I decided to do in this situation. I made a nice and nerdy necklace.
Step 1: Shave Those LEDs!
So, I turned ruefully toward a large yellow LED. I didn't think it would make the fit, but after lots of sanding and a little help from my friend, Mr. Dremel, the new LED was even smaller than my original.
There were also some metal pieces in the way of the LED's space. I took a small screwdriver and worked the metal until the pieces broke off.
So sand down your LED, make it a clean fit, and heat up that soldering iron of yours.
