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.
