Questionable Ethics: Reverse-Engineering a Skinner Box Shock Generator

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 me
