Quick, you need 1000 pieces of wire of the same length, what do you do? The disappointing answer is to put on the miniseries masterpiece Frank Herbert’s Dune and get to work snipping those bits by hand. We usually clamp a scrap piece of molding protruding perpendicular to the bench to use as a length guide in these cases.
The more exciting answer is to build a robot to do it for you. There’s no way you can build the robot faster than you could cut the wire… unless you have admirable rapid prototyping skills like [Eberhard]. He strapped together a barebones machine from two motors, and one switch in no time. Pretty amazing!
Wire coming off the spool feeds through two guides held by a third-hand. The outfeed length depends entirely on timing; two slices of wine cork drive the wire which passes through the open jaws of a wire snip. Those snips are hot-glued in place, with a motor winding up a strip connected to the other handle in order to make the cut. The only feedback is a limit switch when the snip is fully open.
It is entirely possible to get even less advanced. Here’s the same concept without the limiting switch. We appreciate the eloquence of the snipper squeeze method on that one. But for the most part we think you’ll be interested in one that goes about stripping the wire ends as well as cutting to length.
