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…

My city is dying and no one cares. I live in Delhi and it recently hit AQI 1000 - equivalent to smoking 40+ cigarettes daily. Yet people around me still believe you can "build immunity" to air pollution. Frustrated by this dangerous misconception, I built an open-source tool that translates abstract AQI numbers into metrics people viscerally understand: cigarettes you're unknowingly "smoking" and hours of life lost each day. Features: - Real-time conversion of AQI to cigarette equivalents - Daily life expectancy impact calculation - Location-based tracking Live demo:…

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…

A bit more context - the cloth sim is part of my app, Lungy (https://www.lungy.app). It's designed to be an active meditation / relaxation app, so you can play relaxing instruments in space and immersive breathing exercises. The original Lungy is a breathing app available for iOS, that uses real-time breathing with interactive visuals. The cloth sim is a Verlet integration, running on a regular grid. For now, I have tried a couple of different cloth scenes - a sort of touch reactive 'pad', where different parts of the cloth are mapped to different sounds and a cloth that blows…
