Introduction: USB LED Backlight

Really simple build for a USB accent light utilising a generic type "A" USB cable end (the wide one), a 100ohm 1/4 watt resistor, 1/4 inch shrink wrap, and a 3.5 volt LED (I used blue to be different).

Step 1: I Can't Believe It's So Easy...

Image is pretty self explanitory, just solder the LED as close to the USB connector as possible with the resistor on the anode (+) leg of the LED. Slip on the heat shrink tubing, heat until golden brown, and diffuse the tip of the LED with some sandpaper or a disposable nailfile. These work really well behind my desktop, laptop, xbox360, cable box, and dvr.
