Haxophone

I built this during Covid. When I released it, some of the parts went out of stock or skyrocketed in price, no longer making this an economic DIY project. Now that things are getting back to almost normal, I thought I'd share it here and request feedback. This is a very niche project for people who like the same things I do: saxophones, Rust, mechanical keyboards and the Raspberry Pi.

Haxophone launched on November 20, 2022 with 526 votes, #20 of 3,471 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 3 years on.

In plain words

Haxophone is a DIY saxophone project built on Raspberry Pi, combining mechanical keyboard controls with Rust software. Designed for hobbyists interested in musical instruments, embedded systems, and programming, it allows users to build and customize their own playable saxophone hardware. The project includes open-source code and component specifications for those with experience in electronics and software development.

    I built a website for sharing drum patterns2025 · drumpatterns.onether.com · ▲495

    Originally started as a project to restore patterns from now defunct website 808.pixll.de just for myself, but eventually i decided to share it with others. I've seen this website mentioned a couple of times on HN:) Currently it only supports Roland TR-808, but there will be more.

  • I made a tiny device for automatically recording digital pianos2024 · jamcorder.com · ▲590

    Hey HN! A few years ago, I left my cushy big tech job to make hardware. And made the device I always wanted - an automatic piano recorder! I usually play piano improvisationally, and manually hitting record never meshed well with that. But there are always moments I wish I recorded, and now they are! Hopefully it scratches a similar itch for some of you as well! A few of the tech details: * built on an esp32-s3 * custom injection molded enclosure * BLE comms, sd card storage, DS1302 RTC * android & ios apps with Flutter * Shadertoy vfx support for video sharing - Chip

    I used AI to recreate a $4000 piece of audio hardware as a pluginJan 2026 · ▲160

    Hi Hacker News, This is definitely out of my comfort zone. I just wanted to show you guys because I'm super proud of it. It's a 100% faithful recreation based off of the schematics, patents, and ROMs that were found online. So please watch the video and tell me what you think https://youtu.be/auOlZXI1VxA The reason why I think this is relevant is because I've been a programmer for 25 years and AI scares the shit out of me. I'm not a programmer anymore. I'm something else now. I don't know what it is but it's multi-disciplinary, and it doesn't involve writing code myself--for…

  • Audiocube – A 3D DAW for Spatial Audio2025 · audiocube.app · ▲253

    I’ve recently released my solo project Audiocube I wanted to make a 3D DAW, where spatial audio, physics, and virtual acoustics are all directly integrated into the engine. This makes it easy to create music in 3D, and experiment with new techniques which aren’t possible in traditional DAWs and plugins. I’d love to get any feedback on this software (Mac/Windows) to make it better. You can download it for free through the website. Thanks, Noah

  • I built a synthesizer based on 3D physics2025 · anukari.com · ▲512

    I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

  • I've built a tool for musicians using modular gear2022 · patcher.xyz · ▲53

    Hello HN, not many will know what this tool is about, but it's launch day and I always dreamed of posting on HN. Let's start! This is a tool for people using eurorack gear. For synth people. What is cool about my tool is that I show the signal flow with a graph. Here's the official press text: After a decade of stagnation in this space we are excited to present patcher.xyz: the modern way to manage everything modular. It’s a tool for professionals, enthusiasts, and casual wigglers. Novadays artists must develop their own means of taking notes, often on paper, since there is no common format…

  • Talanoa▲340

    Hi 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…

  • I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
