Love his channel. He finds the most interesting devices and topics to talk about. Even when some of the electrical details go over my head, I still learn a lot. I share his fascination with pre- microprocessor electromechanical devices, even though I also love a good microprocessor. I annoy my wife with stuff I've learned from him all the time. Yes, including water heater facts. And because of him, I now run hot water tap until it runs hot before starting my dishwasher to make the first rinse more effective.
Also the man makes me feel contempt over things I had never even considered before. Taillights and blinker behaviors on cars, the rarity of single unit heating and cooling heat pumps, American outlets, power cords, and non-clicky switches, etc. And his indignant rage over product manufacturers competely missing the point of standards or choosing things like aesthetics or marketability over efficiency, safety, or usability becomes my own indignant rage.
