Hi HN, I'm Erwin. I built a small free open-source utility that bridges Bluetooth LE MIDI keyboards into the new Windows MIDI Services stack so any DAW or Web MIDI app can use them as if they were wired. I bought a Roland FP-90X piano partly because it had Bluetooth MIDI. On my Windows 11 PC, pairing succeeded, but my DAW couldn't see the keyboard, and notes I sent from the PC never made the piano sing. After a regrettable number of evenings, I'd separated this into three independent bugs stacked on top of each other. The first one is the famous one: Windows only natively exposes BLE-MIDI…

Hi. I heard HN likes e-paper gadgets so I wanted to share a little side project I’ve been working on with @sqfmi. We’re building Beepberry - a portable e-paper computer for hackers, designed for chatting on Beeper. My day job is running Beeper [0], but I will always have a soft spot for building hardware. I wanted to create a ‘weekend’ device that would let me stay in touch with friends and family, without the distractions of a full smartphone. I imagined a tiny, hackable e-paper screen with a physical keyboard, powered by a Raspberry Pi, that I could use to chat around my home…and pretty…

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…

OpenBLE is an API specification language and client generator for Bluetooth services built on the generic attribute (GATT) profile. Bluetooth development is a mess. Too many datasheets, too little documentation and SDK fragmentation across platforms. I built this tool to improve documentation, version control and development speed for BLE programs. Even though shunned by Apple and Mozilla, Web Bluetooth enjoys wide support and just works. It makes sense to build the frontend for OpenBLE using web Bluetooth. No SDK hell, no installations, wide support albeit experimental. I could ship the…

This is my adventure reverse engineering a De'Longhi coffeemaker's Bluetooth-Low-Energy-based protocol, writing a rust CLI for it, and hooking it up to GitHub actions to let us brew from either the browser or the GitHub app by filing issues (all the coffee are defined in issue templates).
