Show HN: AsteroidOS 2.0 – Nobody asked, we shipped anyway (asteroidos.org)
No usage stats, no tracking, no illusions of mass adoption. The only real signal we get is the occasional person who appears in our Matrix chat going "hey, it booted on my watch from 2014 and now it's usable again" — and that's plenty.
Privacy is non-negotiable: zero telemetry, no cloud, full local control. Longevity is the other half: we refuse to let good hardware become e-waste just because support ended. On the learning side, it's been one of the best playgrounds: instant feedback on your wrist makes QML/Qt, JavaScript watchfaces and embedded Linux feel tangible. The community is small and kind — perfect for people who want to learn open-source dev without gatekeeping.
Technically we're still pragmatic: libhybris + older kernels on most devices since it just works, but we've already mainlined rinato (Samsung Gear 2) and sparrow (ASUS ZenWatch 2) — rinato even boots with a usable UI. That's the direction we're pushing toward.

Questions, port requests, mentoring offers, criticism, weird ideas — all welcome. We do this because shaping a tiny, open wearable UX and infrastructure is oddly satisfying, and because Linux on the wrist still feels like a playground worth playing in.
Cheers, the AsteroidOS Team

[ 3.6 ms ] story [ 50.6 ms ] threadI like that peeking watch face switcher, companies like samsung even after all these years still takes way too long to apply a watch face.
One thing I wish for is Rust support, since its running Linux it should be possible, isn't it?
I have a Tizen-based Samsung watch (Gear Sport, 2017). It's served me faithfully but I'm starting to notice the battery degrading. I'd be interested in trying AsteroidOS with it, if Tizen support ever lands.
What a charming turn of phrase!
You have probably addressed that somewhere, but would it be possible to run your UI stack somewhere else? (PostmarketOS).
My other wish for AsteroidOS would be for it to leverage Wi-Fi better. Not sure how much more energy it would use, but having a longer range for my notifications would be nice (at least on LAN). Being able to perform a few other actions independently of my phone would be great: weather % time updates, e-mail notifications, home assistant control, etc. I get that it may affect battery life as well.
While I'm at it: tiny bug report, but I adjusted the time while the stopwatch was running, and this affected the stopwatch result.
I would love if it would support some of the no-brand Chinese watches you get usually for cheap, the hardware is great but the software usually is bad or outdated. I use one now, I don’t even know anything about it other than the Bluetooth name and app name, but it’s good in measuring distance, blood pressure, heart rate, sleep, among others that’s surprisingly it’s very accurate, it also has a builtin strong flashlight, I like it but with a fully fledged linux would definitely be better.
I'm curious, is the challenge with newer hardware lack of chipset drivers for modern watches, or is there a fundamental difference between the new devices and the old ones that make them completely incompatible with asteroidOS?

I also still dream of one day daily driving a Linux smartphone, but that feels a bit more unrealistic to me, as I have more expectations from a phone, like being able to use bank apps and having a good battery life. But for a smartwatch, which I only expect to show me some biometrics and pass notifications from my phone, this seems perfect.
On this note: aren't JavaScript and QML/Qt too heavy/bloated for a device so small? I expect them to constrain performance and battery life quite a bit, but I admit I don't have a clue and would love to be proven wrong...
Have you looked into Gadgetbridge? https://gadgetbridge.org/gadgets/
I see the supported watches, still have a doubt: what is scenario looking like for the cheap smarwatches from Aliexpress and similar? Any chance to also flash a new firmware or is this limited to more CPU-powerful watches?
