Hi 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…

Using 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.

Simple 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

Hi 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…

I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched. Recently I've updated these with a new "Upside-down" view to complement the rear view, giving a pinout in the right orientation to match your project. The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and…

I've never posted on ShowHN before, but I wanted to share my Xmas 2025 project; to try a new approach to controlling our kids screen time. This also involved massively over-engineering a solution in order to play with a shiny new gadget (and avoid the in laws at Christmas, obviously) I've shared some learnings on AI coding with embedded devices, and how I approached the product design/hardware selection side of things. The Web App is at https://screenie.org - and I'm Open Sourcing the device and web app code later today (links to follow on that site)
