Step 4Soldering the LED's
Once you've got a wire pulled, solder a resistor (I used 69ohm) to the lead of your LED. Once again, another type of paperclip comes in handy.
Now slip a 1" length of heat shrink tubing over the twisted pair of +wires. The heat shrink should be able to fit over your resistor. I use a clip to hold the heat shrink in place, since it'll start shrinking if it gets too close when you're soldering the lead.
Next, solder the +wires to the other end of the resistor (see pics), and the -wire to the ground lead of the LED. I calculated my resistor value to be 75ohms, but the closest I could find was 69ohm. You may need a different value depanding on your LED's. Here's a quick LED resistor calculator that I used.
Clip the leads, and pull the heat shrink tubing over the entire +wire assembly (LED lead, resistor, +wire) as you don't want your +/- shorting together while hooping!
