In honor of the USB contest, and my own passion for making my own wherever I can, I have created what I believe is a totally unique (gasp) Instructable. I could be wrong, of course, but a quick Google search turned up nothing for this, so I'm claiming glory lol. All told, with picture taking, this project cost me around 30 min, and $0 because I had everything lying around that I needed. Let's begin, and remember to vote!!!
Step 1: Items you will need
Straight forward, these are the items you will need to make a custom length USB cable:
A piece of Cat-5 cable, length you desire
Extra USB connectors that come with a 6-in-1 type cable (if you ever had to purchase one like me, you probably have at least a couple you have absolutely no use for)
Razor knife (careful!)
Soldering iron and solder
Wire Strippers (optional)
Basic electrical meter (not pictured)
I decided to make my own cable to 2 reasons: 1, I always make my own cables when I can (the one I bought that came with the connectors was about $15, yikes!), and 2: Cables never seem to come in the length I need. I always want a longer or shorter than you can buy (most USB cables are 6ft long, this one I made is 10ft long).
Step 2: Harvesting the male and female ends
I picked 2 of the connectors that I had absolutely no use for, couldn't even tell you what they might fit. I carefully (to preserve the usb end) used the razor knife to remove the plastic around the connector part I didn't need. I then use the knife tip and small pliers to peel away the metal housing for the unused connector, exposing 4 wires. I cleaned these up as best I could, and proceeded to step 3.
