Some Samsung smart fridges stopped working on Tuesday due to a firmware update.

Korean outlets were the first to report the problems, which affect Samsung’s Bespoke AI line of fridges. Star News Korea, per a Google-provided translation, said that most of the affected devices were four-door fridges from 2024 or later.

I think you don’t need microcontroller for that?

Microcontrollers are cheaper then analog clocks

A 555 is $0.05

A NE555 runs out of sync very fast, so it is not that usable as a clock long term. If you want that you would need further components you don't need for a paduk MCU which is like 3 cents

A 555 can keep time for the 1 minute needed before a fridge beeps that it has been left open. It's not an alarm clock. It doesn't matter if it is off by a few seconds.

Yes they are, but that wasn’t the point.

[–] khanh@lemmy.zip 2 points 2 days ago (1 children)

i think you do, for the counting and beeping.

[–] Asfalttikyntaja@sopuli.xyz 1 points 2 days ago (2 children)

No I don’t. I can use common door switch and a time relay for that, which triggers buzzer. It cost a lot more than microcontroller, but you can do it.

[–] Blue_Morpho@lemmy.world 2 points 2 days ago

A timer circuit is cheaper than a microcontroller.

[–] khanh@lemmy.zip 2 points 2 days ago (2 children)

and why'd you do that when you can save money and get a microcontroller instead?

[–] Blue_Morpho@lemmy.world 2 points 2 days ago

More reliable and the poster is wrong, it is cheaper.

[–] Asfalttikyntaja@sopuli.xyz -1 points 2 days ago (1 children)

That wasn’t the point. You said it cannot be done without microcontroller and I told you it can be done.

[–] khanh@lemmy.zip 0 points 1 day ago (1 children)

practically though, a microcontroller'd be better.

[–] Asfalttikyntaja@sopuli.xyz 0 points 1 day ago (1 children)

And you missed the point again. Congratulations.

[–] khanh@lemmy.zip 0 points 1 day ago

nope... pretty sure they're related.
