The 4 wires to the Tesla caliper are (most likely) two wires for power - which have one polarity to go in and have to reverse polarity to go out, and two wires for either a digital communication, or direct sensing of the Hall sensor.
I think the Hall sensor senses caliper POSITION, not rate, but I am sure that it definitely doesn’t sense if the ghost of Gary is in the area…
Why try and reengineer it, you ask?
Because 1) the Tesla controller was cheap, and 2) I think it’s (the PE controller is) more than I want to spend…. but I’ve given up on the reengineering plan…. I’m not as smart as Jon.

Read Jon's testing instructions. You can easily burn out the electronics on the caliper if you hot wire the thing wrong.
Personally I think for 250, let him do the work. Titania wants some new earrings.
If you want something reliable and that works, PE is THE place to go. I trust him completely on the equipment. On the color choices for LED's and the "Close Encounters of the third kind" flashing strobe lights, that's another thing altogether but no one is perfect.
As a matter of fact, I think those little aliens help him with the designs since some of them just aren't human and sometimes he's entirely too stubborn.
