We open-sourced our compost monitoring tech
I'm from a compost tech startup (Monty Compost Co.) focused on making composting more efficient for households and industrial facilities. But our tech isn’t just for composting— it’s a versatile system that can be repurposed for a wide range of applications. So, we’ve made it open source for anyone to experiment with! One of the exciting things about our open-source compost monitoring tech is its flexibility. You can connect it to platforms like Raspberry Pi, Arduino, or other single-board computers to expand its capabilities or integrate it into your own projects. Our system includes…
We open-sourced our compost monitoring tech launched on November 21, 2024 with 236 votes, #169 of 4,990 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Monty Compost Co. released open-source monitoring technology originally designed for household and industrial composting systems. The platform includes sensors that track gas composition, temperature, moisture, and air pressure, with data exportable as CSV files. Built to work with Raspberry Pi, Arduino, and other single-board computers, the flexible hardware can be repurposed beyond composting for broader IoT and environmental monitoring applications.

Documentation and code for Hack the MontyHome device for extended applications. - gtls64/MontyHome-Hackers-Guide
Welcome to the Monty Home Device Hacking Guide repository! This guide provides step-by-step instructions for extending the functionality of the Monty Home BLE device using a Raspberry Pi. Originally designed for compost monitoring, the Monty Home device collects valuable data on temperature, humidity, and other environmental metrics. Through this guide, you’ll learn how to retrieve, display, and automate actions based on this data. This guide is designed for anyone interested in working with Bluetooth Low Energy (BLE) devices, IoT applications, or environmental monitoring. The Monty Home device communicates over BLE, providing real-time data on temperature, humidity, battery level, and…from github.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Lovable▲1,477Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
