USB Powered Mystic Light

Step 4 Insulate the LED leads prior to attachment

In this step, you will insulate the LED leads.  This is an important step because you do not want the wires to touch and short out.  This could damage the electronic device that is providing power to your Mystic light.

1. Cut two pieces of 1/8" diameter heat shrink tubing so that each is almost the length of each of the leads. Leave enough room at the end for an upcoming step where the leads will be soldered to the USB cable.
 
2. Slide the heat shrink tubing on to each of the leads as shown in the second image.

3. Using a heat gun or other source of heat, apply heat to the tubing until it shrinks around the leads.  When finished it should look like the third image.  VERY IMPORTANT: As you do this step, make note of which lead has the resistor.  You will need to know that in order to properly connect the leads to the USB power cable leads.

Alternatively, if you do not have or want to use heat shrink tubing, you can cut small pieces of electrical tape and carefully wrap them around the each of the leads to protect them from touching and shorting out.
