Wait, my job is not cushy. I think hard all day long, I endure levels of frustration that would cripple most, and I do it because I have no choice, I must build the thing I see or be tormented by its possibility. Cushy? Right.
My Massachusetts home has both radiant floor heating (water pipes in floor) and baseboard water pipe heating (separate part of the house). My son’s New York home has radiators driven by hot water. I can’t recall a home where heating was vented air and not circulating hot water in North East USA.
I trained the raccoons that visit my house at night. I started them out getting a peanuts from a water bottle. Then I tied the bottle to a rope. Then kept raising the bottle higher. At that point, I built an automated feeder system using a linear actuator activated by pulling the rope with the bottle attached. It had LEDs that were green / red to show when the feeder would / wouldn't dispense peanuts. It was all driven by an ESP32, it even had a web page on our LAN reporting how many correct / incorrect pulls were done. Over the coarse of a few nights they figured it out. Raccoons are so cool.
