Active differential probe using the TekVPI interface (Patreon)

I've been using the HP differential probe more frequently lately for stepper motor phase current measurements and power supply noise. Since isolation and current shunts are important points in the OSMU as well, I want to try and make a minimalist version based on an AD830 IC.

It'll only be good up to 15 MHz but that's alright :) http://uk.farnell.com/tektronix/p7520a/differential-probe-5-1-12-5-1/dp/2855080
