The probe has now been finished off with the addition of a 3D printed box to contain the minimal electronics. This makes it self contained except for a 5v wall wart when using it manually. There is an output for connecting to a CNC or other external device when necessary. The schematic for the electronics is in the PDF linked in the first post, otherwise the following pix are self explanatory.

The box could have been made smaller, but the excess volume is just future proofing.
