Hi HN! I’ve been working on an air quality measuring device called Air Lab for the past three years. It measures CO2, temperature, relative humidity, air pollutants (VOC, NOx), and atmospheric pressure. You can log and analyze the data directly on the device — no smartphone or laptop needed. To better show what the device can do and how it feels like, I spent the past week developing a web-based simulator using Emscripten. It runs the stock firmware with most features available except for networking. Check it out and let me know what you think! The firmware will be open-source and available…

Hi HN! I'm Ben, the solo founder of Calibre Analytics: https://calibreapp.com. Calibre monitors websites and applications in a clean-room testing environment from all over the world. Up until January Calibre has been an "inbetween other things" / evenings / holidays kind of project. (Only, oops—I did that for four years.). Last year I knuckled down to get into the position where I could work on it full time. I've spent the last 8 weeks working on "Test profiles" (The launch post is here: https://medium.com/get-calibre/announcing-test-profiles-and-...)…

Hey HN, Nir, Gal and Tomer here. We’re open-sourcing a set of extensions we’ve built on top of OpenTelemetry that provide visibility into LLM applications - whether it be prompts, vector DBs and more. Here’s the repo: https://github.com/traceloop/openllmetry. There’s already a decent number of tools for LLM observability, some open-source and some not. But what we found was missing for all of them is that they were closed-protocol by design, vendor-locking you to use their observability platform or their proprietary framework for running your LLMs. It’s still early in the…

If you've built any web-based app in the last 15 years, you probably used something like Datadog, New Relic, Sentry, etc. to monitor and trace your app, right? Why should it be different when the app you're building happens to be using LLMs? So today we're open-sourcing OpenLLMetry-JS. It's an open protocol and SDK, based on OpenTelemetry, that provides traces and metrics for LLM JS/TS applications and can be connected to any of the 15+ tools that already support OpenTelemetry. Here's the repo: https://github.com/traceloop/openllmetry-js A few months ago we launched…

Hey HN, Joe and Ethan from Tonic.ai here. We just released a new open-source python package for evaluating the performance of Retrieval Augmented Generation (RAG) systems. Earlier this year, we started developing a RAG-powered app to enable companies to talk to their free-text data safely. During our experimentation, however, we realized that using such a new method meant that there weren’t industry-standards for evaluation metrics to measure the accuracy of RAG performance. We built Tonic Validate Metrics (tvalmetrics, for short) to easily calculate the benchmarks we needed to meet in…

This has been a pet project of mine for the past ~5 months. It consists of six visualizations: - Spectrogram: Implements the reassignment method for sharper time and frequency resolution. - Spectrum analyzer: A-weighted, frequency guidelines, loudest frequency tooltip. - Waveform: Colored based on frequency, loudness, or static - Oscilloscope: Tracks pitch and autocorrelates against a reference signal, provides stability. Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. -…

I’m the CEO of AirGradient, where we build open-source air-quality monitors. Two months ago I decided to build our first native iOS app myself. I’ve been coding on the side for ~15 years, but had never touched Swift or SwiftUI. Still, I went from empty repo to App Store approval in exactly 60 days, working on it only on the side. The app itself is a global PM2.5 map with detail views, charts, and integration with our open-source sensors -straightforward, but fully native with Swift and now live on both iOS and Android (native Kotlin version). The interesting part for me was actually not so…
