I have the unfortunate "habit" of writing in the style of chatgpt, even before chatgpt existed. So no, not a chatgpt comment.

The article is about stopping the fridge beeping when you leave the door open. Your comment is about removing a fridge from the wall.

Maybe you should reread the article? The introductory motivational paragraph talks about the difficulty of getting to the main board which is in the back of the fridge.

I modded my fridge... I went armed with an Arduino... And when I got to the fridge main control board I found it was already an Arduino! Or at least it was an atmel 168p running the Arduino bootloader with the distinctive 1 second startup delay.

It is a US style fridge freezer, but made in Turkey for the EU market. 1 compressor, 2 fans, 1 defrost heater, 1 door edge heater, 2 door switches, 1 light, 4 temperature sensors, an LCD screen, 2 status LED's, buzzer and a button.

Alas - I couldn't be bothered to reimplement all the fridge functionality or disassemble the assembly code, and I realised the mod I wanted (disable the door edge heater) could be achieved by simply unplugging the wire.

I’ve lost count of the similar mods I have done on various household items over the years. Often timer related like this one… but I would have used an attiny85 or similar MCU instead of the 555 because of the lower parts count and less analog parts to drift out of spec or dry out. I’ve found that just with a drawerfull of attiny chips I don’t have to keep a cabinet full of other stuff, and so far I’ve only noticed improvements in reliability despite the fact that I’m throwing 100,000+ times the complexity at the problem to be solved. For many jobs it’s 6-8 pins and you’re done, and a dead-bug SOIC in shrink wrap is tiny.

Is this one of those chatgpt comments?

It's not the style so much as commenting on a random unimportant part of the article instead of the substance of the article. I had to reread to figure out why you were addressing the ability to move the fridge since it didn't even click as being mentioned in the article on the first read.
