Wow, this is such a cool hack. Taking a Casio F-91W—literally the indestructible watch—and giving it a microcontroller brain while keeping that retro LCD? Pure genius. The pluggable sensor module (starting with a thermometer!) is what sold me. Now I’m daydreaming about slapping on an air quality sensor, an NFC chip, or… honestly, why not a tiny radiation detector?
But flashing firmware via USB on a Casio? That’s the kind of absurdly cool detail that makes me love hardware tinkering. It’s like giving your grandpa’s old pickup truck a Tesla battery but keeping the patina.
Not passing any judgement on this specific comment, but I've seen a fair bit of what you describe in other comment threads on HN as of late, and I can't help but wonder — why? I get that some people bot on Reddit because you can sell the accounts to spammers and such later, but here? I just don't get why anyone would do it on HN, but it's definitely a thing.
Huh. Fun to see this on HN again (all to all the Casio love). That watch isn't what I wear daily. Instead, I have a Casio Lineage (this model: https://www.casio.com/europe/watches/casio/product.LCW-M170D...) which I love for its lack of connectedness, that it keeps itself charged from the sun, and sets itself from DCF77.

Huge props for keeping it open and hackable.
