I'm working on a free high performance address matching (geocoding) library. As it turns out I blogged about it just today: https://www.robinlinacre.com/address_matching/

#772Still working on: an enclosure-compatible open-source version of the 2nd gen Nest thermostat. It reuses the enclosure, encoder ring, display, and mounts of the Nest but replaces the "thinking" part with an open-source PCB that can interact with Home Assistant. - The encoder ring which works like an LED mouse, but in reverse: Fully reverse-engineered and on its own demo PCB - The faceplate PCB, which does the actual c…
M5 Stack sells a nice controller knob if you don't have a used nest handy

> As a versatile embedded development board, M5Dial integrates the necessary features and sensors for various smart home control applications. It features a 1.28-inch round TFT touchscreen, a rotary encoder, an RFID detection module, an RTC circuit, a buzzer, and under-screen buttons, enabling users to easily implement a wide range of creative projects.
> The main controller of M5Dial is M5StampS3, a micro module based on the ESP32-S3 chip known for its high performance and low power consumption. It supports Wi-Fi, as well as various peripheral interfaces such as SPI, I2C, UART, ADC, and more. M5StampS3 also comes with 8MB of built-in Flash, providing sufficient storage space for users.
I've build a few HA-compatible systems using M5Stack products; mostly the Atom-S3 Lite connected to various sensors and lights.

#773Built a single page website - https://whythink.org. Nothing fancy, just a simple qotd app

#774As a European missing a managed hosting solution, me and a buddy of mine are building an alternative: https://ploi.cloud The goal is quite simple, allow developers to host their application with easy straight forward pricing. We are about to launch very soon. Everything is built on Laravel/PHP. We are open to beta testers, so if you feel you want to test this please drop me and email in my profile.
Had a similar idea. Wishing you both good luck. Europe needs more hosting solutions.

#775Building https://www.typequicker.com Long-term, passion project of mine - I'm hoping to make this the best typing platform. Just launched the MVP last month. The core idea of the app is focusing on using natural text. I don't think typing random words (like what some other apps do) is the most effective way to improve typing. We offer many text topics to type (trivia, literature, etc) where you type text snippets. We…
very cute. good luck!

#776I'm working on yet another computer vision graphical annotation tool — but with a twist. I have this wild idea that labels should live inside the image itself, stored as dedicated text chunks within the PNG file, completely eliminating the need for sidecar files.
The tool will support four annotation modes: Box, Polygon, Mask, and Keypoints — each with its own dedicated panel. You can switch modes by clicking the color-coded buttons on the toolbar, complete with smooth transitions. Labeling is a tedious task, so a bit of satisfying UI action here and there can't hurt.
It will also export labels to all major formats — and can (re)generate any sidecar file structure when needed.

#777I’m working on https://finbodhi.com — a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. It helps you track, understand, and plan your personal finances — with a proper accounting foundation. It's interesting in many way. Using double-entry (it's a perspective shift), the technical challenges of building local-first app, UI/UX &…
This looks very interesting. Do you support double entry bookkeeping not avoid errors? Is there support for transactions with more than one currency?

#778I'm building an app to help users find free and paid street parking in Vancouver: https://instaparkr.com/
While apps like Parkopedia and SpotAngels tackle the same problem, their one-size-fits-all approach often results in incomplete, missing, or outdated data. My approach is different: go deep on one city at a time by combining multiple publicly available datasets. This doesn't scale horizontally since each city has different data sources and formats, but the goal is to become the definitive parking resource for one city, build automation to keep it current, then methodically expand city by city.
If you are based in Vancouver, do give it a go. Your feedback would be awesome!

#779Repo: https://github.com/mochilang/mochi I'm building Mochi, a small programming language with a custom VM and a focus on querying structured data (CSV, JSON, and eventually graph) in a unified and lightweight way. It started as an experiment in writing LINQ-style queries over real datasets and grew into a full language with: - declarative queries built into the language - a register-based VM designed for analysis an…
This is awesome. I often start to reach the limits of my patience trying to figure out how to do things in `jq` DSL. This seems way more friendly.

#780Hey HN – I'm working on OneBliq https://onebliq.com, a lightweight tool to help teams plan and track Azure costs collaboratively, without the usual enterprise overhead.
We built it because managing cloud budgets often turns into a spreadsheet mess, or worse, a never-ending consulting engagement. OneBliq lets you:
* Split and allocate Azure costs by cost centers, teams, or projects
* Visualize current spend and attention areas at a glance
* Experiment with plans and projections without complex tooling
* Skip sales calls and long onboarding – just install and kick the tires
It's still early, but we're seeing traction with teams who want clarity without complexity. Happy to answer questions, share more, or get feedback.
Would love your thoughts – what would make a tool like this useful (or useless) for you?
