Man, I fucking love watching this guy. He’ll talk about the most niche things and I love learning about it. He inspired a presentation I gave on how rice cookers work
Short answer — the internal “switch” is held in the on position by a magnet. Magnets become much less effective when they get hot, and while there is still water in the cooker the maximum temperature will be 100C. Once all the water boils off the temperature quickly rises — but the magnets stop being able to attract the switch when they hit around 102 - 103C or so and release the switch, turning the machine off.
So all has is a switch connected to a magnet next to the bottom of the pot. That’s it. Physics does the rest.
Most thermostats in electronics such as kettles and cookers use a bi-metallic strip inside, where the two metal layers expand at different rates.
The contacts in the switch are physically pulled apart by the strip bending when the desired temperature is reached.

I remember seeing him (or someone claiming to be him) here on lemmy after the big migration from the-place-we-don’t-talk-about. Someone was not impressed by him and told that to his face, politely. Never noticed him around since.
lmao. I have a brother who’s a lot like me and loves to tinker (not too young that this is irresponsible though), so when i need to throw something on to keep him occupied while i work, i know Technology Connections is a safe bet.
That’s awesome. With what does he tinker? Some sort of screenshot technology?
I’m the youngest in my family, so I’ve never really had the chance to guide someone’s growth until relatively recently. I take a great amount of pride in directing my kid toward things that will expand their creativity and curiosity. Hopefully you enjoy doing the same for your younger brother!
I try to encourage him since all my tinkering was self taught. I know I’d appreciate having a guide or even just a friend to talk to about those ideas. And he definitely comes up with some ideas that help my own tinkering.
Right now he’s really into engineering and has this box that comes monthly that I paid for him that teaches him Engineering principles. I think it’s done by Mark Rober? Not really tinkering but He also likes making models for 3D printing and he’s been trying to get into Programming, unfortunately I think that curiosity keeps distracting him though.

That’s awesome and a great gift.

He has a ton of ideas. Right now he’s gotten really into Robotics and specifically joined his local FIRST team. This gave him the idea to build a robot of his own. I’ve tried to support him but damn can those things get expensive fast
It’s awesome that he has so much creativity and motivation! My wife was in FIRST way back again and I think my SIL met her husband through it. I was homeschooled, but probably would have loved it if I had gone to public school. Hopefully it’s beneficial (if expensive) to you guys as well.
Didn’t its founder invent the Segway or something? Then go on to drive one off a cliff …
I could have sworn I remember hearing the founder died of Covid back when I was in FIRST myself, it’s possible I’m confusing him for someone else though.
Luckily the robotics team covers all the parts for their robot so he’s getting a bit of the experience

And how do they work?
They do the thing until the thingymajogger flips, obvs.
Funny you should ask https://youtu.be/RSTNhvDGbYI

https://en.m.wikipedia.org/wiki/Curie_temperature I doubt they’re using magnets, especially considering how hot they have to get to lose their magnetism as you suggest.

He was on Mastodon for a bit but I think he didn’t like the culture
This morning, I told my brother I was watching YouTube. He said “what are you watching and, if it’s not Technology Connections, why not?”
