This wrapping machine makes wire harness creation a breeze

Many merchandise require using wire harnesses, that are primarily bundles of cabling that join one subsystem to a different, comparable to a automotive engine’s sensors to the ECU. DIY tasks may also discover themselves needing one, however having to handle the wiring with out tangles or undesirable bends generally is a problem.

YouTuber Mr. Modern has created a easy wire harness wrapping machine that takes the consumer’s selection of tape and shortly spins it across the bundle. He began by chopping out the bottom and stuck ring out of plywood earlier than milling the spinning ‘C’ disk from acrylic. As soon as these components had been hooked up collectively and a set of bearings/pulleys had been added across the transferring disk, a timing belt was looped on one half to an awaiting stepper motor.

This motor is accountable for shortly rotating the tape across the harness inside the disk, and it’s managed by an Arduino Nano. The wiring was simplified by means of using a customized PCB, which accommodates inputs for energy and activation, an A4988 stepper motor driver board, and extra energy administration circuitry. 

Altogether, this undertaking transforms the in any other case tedious means of bundling a number of cables collectively into a much more environment friendly one with a easy press of a restrict swap. You may see the undertaking in additional element beneath.
