Today I will show you how to make a female-to-female multipin connector cable for standard headers with help of some heat shrink tubing. You can use same technique for making male to male or male to female cables with as many pins as desired. It's a real "ghetto" way (compared to using special crimp pins, headers and crimping tool) to make a cable, but will do in a pinch.
Heat-Shrink Tubing of 3 various sizes (from really small for single wire, to large one that can cover 4 pin connector). You can find it at RadioShack or Home Depot.
Pieces of wire (I got mine from CAT-5 cable I had)
2.54 mm Single Row Female Pin Header (eBay)
Wire strippers (24 awg)
3rd hand tool (optional)
Heat Gun or hair drier
Step 1: Cut Pin Header row
With wire cutters carefully break pin header row to the size you need. I found it’s better to brake on the next pin, so if you need 4 pins, break at 5th.
Step 2: Prepare Wires
Cut your CAT-5 cable, slice outer shield with a knife and remove wires. Make them as long as needed and use as many as number of pins you will have. Strip ends (small portion) with wire strippers. Pre-Tin wires with soldering iron
Step 3: Solder wires to pins
Pre-Tin header connectors. I left some extra solder lead on them on purpose.
Solder wires to header connectors. Keep them parallel and check if they are holding.
Very important to know which color goes to which PIN. Use paint, nail polish or marker to mark one side, this will be your Pin #1.
