You know this problem: you own about a million cables, but not the one you need right now. If you have once in your lifetime the problem that you need a 3,5mm-jack-to-cinch-cable, this instructable will teach you how to build this cable from a random jack-to-jack and cinch-to-cinch cable.
Things you need:
* soldering iron
* heat gun (or a lighter)
* shrink tubings (optional)
* tape (because need tape, no matter what you are doing)
* at least one piler
Step 1: Cut the Cables
Cut your jack- and cinch-cable in two halfs.
Step 2: Strip Time
Strip all the cables so you have access to the copper inside. The jack cable should have 3 cables (1 is the shield/ground) inside, each of the cinch cables should have two cables inside.
Step 3: Twist It, Baby!
Twist all the cable ends until they stick nice together, this is the preparation for the soldering job described in the next step. Make sure no single copper wires are sticking out.
Step 4: Pre-sold It
To make it a little more easy for you to get the cables soldered together, you should add some solder on every cable end.
Step 5: Prepare You Shrink Tubings
Don't forget to attach your shrink tubings. Add one for every non-ground-cable and also don't forget to attach a big shrink tubing to cover the whole cable.
Step 6: The Wedding
Its time to say hello! Take a deep breathe and keep a steady hand. Solder all the cables together. In the base case the colours of the cable match, like in our case! After you soldered a cable pair together, heat the shrink tubing to keep your new connection save.
Make sure you solder all ground-cables (3 cables) together.
Step 7: Final Protection
Now, move the big shrink tubing on the cable and heat it. It should protect your cable now.
Step 8: Tape!
In our case, we added another shrinking tubing to protected the shrinking tubings inside it. Since this shrinking tubing shrinked not enough, we used some tape to keep it on its position.
Step 9: Done
Et voilà, you got a working 3,5mm-jack-to-cinch-cable!
