When looking for resources for wire, one needs to look no farther than an old printer cable! yes, you too can extract up to twenty five colourful wires, hidden in a simple disposed old cable. First, cut off the ends (pesky ends!) and select a length that will work for your projects, i rarely need more than ten inches of wire, so i cut my cables up by the foot. take a blade (exacto or other knife) and place an incision down the outside plastic insulation of the cable. don't dig too deep into the cable, as to not cut the internal wires. the outside plastic/rubber that holds the many stranded coloured wires should pull off relatively easily. and blam! you now have twenty five colour coded wires, each twelve inches in length. I always look for cables like this in the trash or being disposed of at the office. its an easy way to recycle!
