Bob over at Making Stuff didn’t want to purchase an expensive cable for his digital calipers, instead he decided to build it. A small 3D printed grooved part with a few connected wires is all that is needed to connect to the data output port of the calipers. A logic level converter is needed to change from 1.5 volt output of the calipers a voltage high enough for a solid logic level 1. Now this can be used as a precision measurement input on a microcontroller project.
