Tricks of the trade: Twisting wire bundles @ EMSL –
A common problem that you may come across when building “a box” to do something– whether a one-off gizmo or bona fide scientific instrument –is the rats nest of wires. A similar problem occurs when you need to run a bunch of basic wires out from your box to other devices. Unless there’s a standard cable lying around that does exactly what you need, you can end up with messy tangles of wires outside of your box as well. There are many well-known solutions of course, as varied as elegantly laced wiring harnesses, cable ties and teflon spaghetti sleeving, heat shrink tubing and cold shrink tape, and (possibly for the brave and/or insane) duct tape and paperclips.
