- 1IMI 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 guys, I built a route planner that is mostly focused on bike touring and using existing bike infrastructure. For each request you're shown what bike tracks/trails your route uses and can further explore them by showing them on map or going to the official trail route. The main idea for the app is to have a friendly and easy to use planner that would make heavy use of official bike trails data (mainly from OpenStreetMap) and make it easy to plan a longer trip using the best possible bike routes out there. Currently the app only works for the Euro region but I'm planning to add North…

Hi HN! This is a trail companion web app (think AllTrails) I hacked together in a couple weeks time. I was inspired to create this project while training for an extended backpacking trip. My motivation was to create a UI tailored exactly to my liking, and to be able to track my progress along the trail without draining my battery. I also wanted to experiment with PWA technologies. I successfully used it on my five day adventure along the Knobstone Trail in southern Indiana, and even though it's web-based it hardly consumed any battery life on my old first-gen Pixel XL. It's set up currently…

Hey HN OpenCopilot is an OSS framework which helps devs to build open-source AI Copilots that actually work and embed into their product with ease. Why another LLM framework? Twitter is full of impressive LLM applications but once you peel off the curtains it’s clear that they are just demos. The reason being because building an AI Copilot that goes beyond a Twitter demo can be complex, time-consuming and unreliable. Our team has been in the AI space since 2018 and built numerous LLM apps & copilots. While doing that, we got approached by many startups saying they’d also like to build a…

Open Notebook▲144Open Notebook is a tool where you can upload your own sources - PDFs (textbooks, research papers), Github repos, documentation websites, and other URLs. Once uploaded, you can either chat with an AI about them or run “apps” on top of those sources. Apps can be anything. Right now, I’ve built the following: - turn articles into short video overviews - create a mind map of the source - create summaries or other reports about the source - generate quizzes or flashcards to help study the source You can also remix existing apps or create one from scratch. I built this because I wanted to make…

I use a ton of 3D Files as I love 3D printing in my spare time and I usually exchange them over Gmail and store them in Google Drive etc.. Google does not have a 3D Preview of files so I've built a small Google Workspace Addon that opens the file into a clean "Google like" web app that supports most files. Other solutions existed but they were full of ads and looking absolutely terrible. It got a bit of traction (around 400 users) on the store so thought I would share it here! Would love to have feedback! Each file is treated purely in the browser for maximum privacy

Built this because people working with large document sets had no free tool that handled batch processing cleanly. Tesseract is free and runs locally. For anything that needs more accuracy — Google Vision, Gemini, or any OpenRouter model — you bring your own API key. No subscription, no markup on your usage. Export as TXT, JSON, XML or PDF. AI engines support custom prompts so you can translate, extract form fields, or get structured output in one step.
