When people say the key to a happy, long-lasting marriage is communication, they generally mean the verbal kind: talking things out with your spouse, sharing your feelings, and all that lot. [Rich] AKA [Thumblegudget] took it another way, and built a engine-room telegraph for intramarital communication.
Now, this is less crazy than it sounds. Like the ship’s telegraph, which matched the position of an indicator on the bridge and in the engine room, [Rich]’ telegraph pairs an indicator in his office with one in the living areas of the house. He sets himself to “busy” and the arrow on the matching unit in the basement moves to that position. This naturally goes both ways, which allows his wife to point the needle to remind [Rich] that it may be time for hugs, dinner, or — most essentially for a brit — tea.
In operation each unit has a gimbal motor paired to a rotation sensor and an ESP32-S3 driving it. Thanks to that rotation sensor, the gimbal motor is programmed to lock itself into the positions on the wheel when you poke it, and the ESP32 wirelessly synchronizes the two units. A moving arrow might not be enough to get [Rich] to come down to dinner, so just like the ship’s telegraph you may remember from Titanic, [Rich]’s comes equipped with a bell to draw attention to itself.
Given [Rich]’s wife participated in the video and isn’t filing for divorce, it seems he may be onto something. Perhaps good communication doesn’t need to involve cumbersome human speech at all; maybe all a marriage needs is a telegraph like this and some paddles to send more complicated messages via Morse code.
