24 alternatives to AsteroidOS 2.0 – Nobody asked, we shipped anyway
Hi HN, After roughly 8 years of silently rolling 1.1 nightlies, we finally tagged a proper stable 2.0 release. We built this because wrist-sized Linux is genuinely fun to hack on, and because a handful of us think it's worth keeping capable hardware alive long after manufacturers move on. Smartwatches don't really get old — the silicon is basically the same as it was a decade ago. We just keep making it useful for us. 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…

Open Wearables▲631Hi, I'm Bart, one of the maintainers of Open Wearables. For the past few months we've been building an open-source, self-hosted backend that normalises health and fitness data from multiple wearable providers (Garmin, Whoop, Apple Health, Samsung Health and others) into a single AI-ready REST API - and thought it was worth sharing here too :) We built this out of our own experience doing custom wearable integrations for clients, and from working with paid SaaS solutions that often lack the flexibility to customise data pipelines or debug what's actually happening under the hood.…

- 2IMI made a tiny camera with super long battery lifefrom $200/mo▲843
Hey HN! A few years ago someone kept trying to steal my motorcycle, so I decided to make a small camera with really long battery life to catch them. The hardware/software is totally open source, but the companion app only supports macOS currently. (I'm a big fan of native apps, and didn't want to block releasing on Linux/Windows support.) I wrote some blog posts about the process: PCB design: https://toaster.llc/blog/pcb Enclosure design: https://toaster.llc/blog/enclosure Image pipeline:…

Hey HN! I'm the developer of one of the most popular Android clients for HN, Harmonic for Hacker News. Over the years I have recieved many requests to open source the app which I am finally doing - sorry about taking so long :) Having been very busy working on my PhD during the last two years - Harmonic has not recieved the attention it deserves. I therefore hope that open sourcing it can give it a new lease on life. I also hope that by posting here many of the nice people who have reached out to me will notice that the app is finally open source. I'm also happy to answer questions about the…

Unlock Apple Watch's cutting-edge health data on your Android phone, synced to any Health Connect compatible app. Get Android notifications on your wrist, reply to messages, control media playback, and more. Hi all! I've always believed the best hardware and the best platform should work together, regardless of who made them.

Merge connects your…

ServiceRadar is an open-source platform for distributed, secure network management and observability, scaling to 100k+ devices. Born from frustration with complex traditional NMS tools like Zabbix, it bridges legacy (SNMP/syslog) and modern (gNMI, OTLP) protocols for cloud-native environments. We built ServiceRadar to simplify monitoring hybrid telecom networks, evolving it into a Kubernetes-native solution with Helm and Docker support. It uses mTLS with SPIFFE/SPIRE, NATS JetStream for event streaming (90M+ EPS), and SRQL for intuitive queries. Integrated with OpenTelemetry,…
