Xcc700: Self-hosting mini C compiler for ESP32 (Xtensa) in 700 lines▲154
Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…

Look Ma, No Linux: Shell, App Installer, Vi, Cc on ESP32-S3 / BreezyBox▲327
Example repo: https://github.com/valdanylchuk/breezydemo The underlying ESP-IDF component: https://github.com/valdanylchuk/breezybox It is something like Raspberry Pi, but without the overhead of a full server-grade OS. It captures a lot of the old school DOS era coding experience. I created a custom fast text mode driver, plan to add VGA-like graphics next. ANSI text demos run smooth, as you can see in the demo video featured in the Readme. App installs also work smoothly. The first time it installed 6 apps from my git repo with one command, felt…

I open-sourced my AI toy company that runs on ESP32 and OpenAI realtime▲177
Hi HN! Last year the project I launched here got a lot of good feedback on creating speech to speech AI on the ESP32. Recently I revamped the whole stack, iterated on that feedback and made our project fully open-source—all of the client, hardware, firmware code. This Github repo turns an ESP32-S3 into a realtime AI speech companion using the OpenAI Realtime API, Arduino WebSockets, Deno Edge Functions, and a full-stack web interface. You can talk to your own custom AI character, and it responds instantly. I couldn't find a resource that helped set up a reliable, secure websocket (WSS) AI…

Sosumi.ai – Convert Apple Developer docs to AI-readable Markdown▲133
I got tired of Claude hallucinating Swift APIs. It does a good job at Python and TypeScript, but ask it about SwiftUI and it's basically guessing. The problem? Apple's docs are JavaScript-rendered, so when you paste URLs into AI tools, they just see a blank page. Copy-pasting works but... c'mon. So I built something that converts Apple Developer docs to clean markdown. Just swap developer.apple.com with sosumi.ai in any Apple docs URL and you get AI-readable content. For example: - Before: https://developer.apple.com/documentation/swift/double - After:…

C++ library for embedded and IoT projects (ESP32)▲8
Hi everyone. I've recently released control-components, a C++ library I've been using for most of my embedded projects. It is written in C++17 (with some features from C++20) and uses STL and FreeRTOS under the hood. It contains a lot of building blocks that is commonly used in embedded and IoT projects: finite state machines (FSM), various counters, synchronisation primitives, system loops, sensors, schedulers, HTTP, WiFi, Web GUI, and much more. It also provides GitHub CI workflows for build automation (ccache, various checks). In general, it's a good starting point for an ESP32 project.…

Open-source library documentation for LLMs▲12
Docs.codes generates simple markdowns for open-source libraries that you can add to the context of your LLM assistants, helping them generate better code. Here's a quick walkthrough with pypi/mem0ai as example: https://youtu.be/SKZol8G_tIE LLMs struggle with generating correct code when using lesser-known libraries or dealing with major version changes that happen after their training cutoff. With these markdowns, you can ensure that your LLM chat/coding assistants have up-to-date knowledge of the library's API and usage patterns. We built this using the latest…
