Step 2: Prepare the LED

The power button that I pried out of my old computer is fairly large in size, I could fit a 3V battery inside of it. I used a 10mm blue LED and sanded it so that the light would be more diffuse.  I bent the poles of the LED to fit around the button battery and then taped them so that it would stay put.

Obviously, not all power buttons are the same size, so if you make your own you may need to explore smaller size options for the LED and battery such as sequin LEDs and CR927 3V batteries.
