Printable wire stripper lights up when you hit the conductor

Agonize no more over stripping the insulation off of tiny wires like those used in ribbon cables. For years we’ve used razor blades to do this, as the tiniest wires don’t have a slot on our trusty wire strippers. But often we cut all the way though the conductor (or many of the strands) when doing so. [Bjbsquared] came up with this design that will alert you when you’ve hit the conductor.

It uses the two metal razor blades as electrodes in the LED circuit. When anything metal connects the two, the LED will be illuminated. This way you know you’ve cut far enough, and should be able to tug the insulation off of the wire. This image only shows half of the printed unit, a second piece covers up the inner workings, and helps keep stray fingers away from the edges of the blades.

Overkill? We don’t think so, and we hope everyone will agree this is a wonderful design.

Hacking strippers to do your bidding

[Alex] knows his strippers.

By his estimation, he has stripped millions of wires over the years, and he has seen his fair share of wire strippers come and go. That cheap set of wire strippers you have with the graduated holes, or that adjustable stripper you squeeze as you pull the wire through? They just stress the insulation as well as the wires you are trying to strip – he says you might as well just use them in your tackle box.

His favorite style of wire stripper is the automatic kind that grip the wire, then cut and remove the insulation just by squeezing the handles. His issue with this particular tool is that it’s difficult to get a uniform length of stripped wire when working in volume.

Since [Alex] needs uniformity in his line of work, he modified a set of automatic wire strippers to include an adjustable wire stop. He determines the length of wire he needs, adds or removes some washers from his wire stop, and off he goes. It’s a very simple yet very useful hack, depending on your application. We bet it is probably one of the most accurate ways to get uniform length, this side of a fully automatic wire stripper.
