Building a GPS receiver2024 · axleos.com · ▲552Hi everyone! Shortly after publishing my iOS 4 jailbreak last October[1], I got to work on my next hobby project: a from-scratch homebrew GPS receiver, which can solve the user’s location solely from billions of radio antenna samples. I took a commodity SDR (alongside the Python standard library and numpy) and built a signal processing pipeline that can detect and track GPS satellites over many minutes, drop and pick up satellites as they come in and out of view, and precisely determine the user’s position and clock inaccuracy. All told, gypsum can go from a cold start to a fix on the user’s…
TinyPilot – Build a KVM over IP using a Raspberry Pi2020 · mtlynch.io · ▲756Using only a Raspberry Pi and an $11 video capture dongle, you can create your own KVM over IP device, allowing you to send keyboard input to a remote computer and capture its display.
Multi-monitor KVM using just a USB switch2024 · github.com · ▲397Simple KVM lets you control multiple PCs from one mouse, keyboard and monitor(s). It is similar to Haimgel's display-switch (https://news.ycombinator.com/item?id=29608967), but it provides a GUI which hopefully makes it a bit easier to set up. It also supports hotkeys which effectively lets you alt+tab between computers. I was surprised by the star-to-download ratio (55:400) on GitHub, so I thought I'd post it here as it might be useful to someone. Feedback welcome! Thanks, Fidel

Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB2024 · github.com · ▲233Hi HN! I built Bluetooth USB Peripheral Relay, a tool that lets Bluetooth devices (like keyboards and mice) connect to USB-only hosts using a Raspberry Pi Zero W. Why? My friend needed a way to use his Bluetooth mouse and keyboard on a PC with Bluetooth disabled due to policy restrictions. This tool acts as a bridge, relaying Bluetooth input over USB. It also lets you use Bluetooth peripherals with older devices that only support USB input. Tech: Written in Go, optimized for Raspberry Pi Zero W. I love HN’s community and often lurk here—I’m hoping this project is useful or at least sparks…

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…
