Long time, no see - it's been a while... Hard to make videos when caught up in the daily grind and life's problems.
An ethically questionable device here is the IBD (Institute of Experimental Biology) TGS-1 electromechanical shock generator. It's an artifact of behavioral science used with the infamous Skinner box, and it applied AC current to an electrified floor of the box, delivering an electric shock to the animal inside, used for negative reinforcement in operational conditioning experiments. The device has controls for shock duration and intensity (current) and features a motorized distribution switch identical to the one I used in my Electro-Mechanix art installation (https://www.youtube.com/watch?v=nvpzoxPvWHw) and very similar to what @FranLab once got from her local university, leading me to suspect that hers was also used in a similar setup.
I got three or four of these shock generators from my friend from medical university, together with lots of other scientific and medical tech. After disassembling one of them, I decided to restore another one to a working order, get a grip on the controls, reverse-engineer the thing and make a video of it. The rest is in the Vault for the time being.
No living creature, neither me nor Mr Rattman the lab assistant, was shocked through making this video. I'm not @ElectroBOOM, LOL.
@CuriousMarc briefly featured a DEC PDP computer controlled experimental setup for Skinner boxes in https://youtu.be/PcNekvIxjTo?t=507 - the orchestration system used with my generator was probably a lot simpler.

Also showing some new stuff and improvements to the lab and filming setup in the further part of the video, if you're interested. It's more of a sneak peek, not a fully fledged "Keri's Studio Behind the Scenes" kind of video. Not talking your ears off about NDI here... yet.

Now I noticed that the C930e loses its white balance when my hand is in view, and the Kiyo Pro tries to focus but often can't - just like me! ADHD shenanigans, haha.
