As most of you know, getting a descent length of VGA monitor cable is a costly thing. With this instructable I'll show you how to make a 15m long VGA cable, out of plain ol' CAT5 network cable.
Step 1: Strip you filthy cable you! Strip!
To make life a bit easier, strip of about an inch of the CAT5 outer insulation. And behold: 8 precious wires in pretty colors. Make sure you strip about 2/3 mm of the inner wire insulation. Try using an wire stripper. I use my teeth, because Macgyver does it too. Don't make it to long as it could shortcut when fiddling all the wires in the VGA connector.
