Annoyed by excessively-long cables? Tired of the dull drudgery and ugly results of bunching up the slack and wrapping it with a twist-tie? Suffer no longer, because the solution is to make your own coiled cables!
[Dmitry] is annoyed with long, unruly cables and shared a solution he learned from the DIY keyboards community: coil them yourself with a piece of dowel, a hair dryer, and about 10 minutes of your time. However, it’s just a wee bit more complicated than it may seem at first glance.
The process begins with wrapping a cable around a mandrel, then heating it as uniformly as possible to thermoform the jacket, but the instructional video (embedded below) says that all by itself that isn’t quite enough to yield lasting results. After heating the cable and letting it cool, the coils will be formed but it will not hold the new shape very well. The finishing touch is to “reverse” the direction of the coils, by re-wrapping it backward around the mandrel, inverting the coils upon themselves. This process is awkward to explain, but much simpler to demonstrate. This video by [DailySetupTech] explains this process around the 2:30 mark. That final step is what yields a tightly-wound, springy coil.
The nice part about using this process as a cable management technique is that it is possible to coil only a portion of a cable, leaving the exact amount of uncoiled slack required for a given application. Keep it in mind the next time some cables need managing. And if you don’t want to coil a cable but still need it out of the way, you might find this design for a DIY cable chain made from a tape measure useful.
