Jester:
I'm using it this morning, 19bit AC/DC load, mostly use it in AC mode. 250V, 40A

Edison:
Well used HP case, unfortunately these boxes do not fit deep into my workplace
👍 beautiful work 👍

This is a very simple low-voltage differential probe I made a while ago, mostly to use at audio frequencies, so is just built with a TL052 with some 0.1% 100k resistors.  I had it open today to check which op amp I used so decided to take a picture.  The front-panel switch is to engage a 40 kHz 2nd-order Butterworth low-pass filter (very useful when measuring outputs of some class-D amplifiers).  I measure 50+ dB CMRR in the audio band.  It frees up a channel on my 2-channel scopes, so is pretty useful.

Not in use now, but in progress:
Power inductor checker, inspired by:

I designed the board and made some changes, the first test showed that some improvements are still necessary.
When I have them on the way, a separate thread will follow.
