   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…

    Tommy – Turn ESP32 devices into through-wall motion sensors▲110

    Hi HN! I would like to present my project called TOMMY, which turns ESP32 devices into motion sensors that work through walls and obstacles using Wi-Fi sensing. TOMMY started as a project for my own use. I was frustrated with motion sensors that didn't detect stationary presence and left dead zones everywhere. Presence sensors existed but were expensive and needed one per room. I explored echo localization first, but microphones listening 24/7 felt too creepy. Then I discovered Wi-Fi sensing - a huge research topic but nothing production-ready yet. It ticked all the boxes: could…

    Astra – a new js2exe compiler▲61

    Hi everyone I'm new here and i wanted to introduce my project i've been working on. Astra is a simple but powerful node.js to exe compiler. It uses esbuild and Node SEA. It uses postject to inject your code to nodejs binary. It focuses more on compiling cli and Servers like pkg or nexe (express) than fullstack applications like electron or tauri. It has rich ESM and typescript support. It has good DX and cli UX. I made it bc i didn't like using pkg or nexe, they cause a lot of problems with esm. LIMITATIONS: Now it has problems compiling projects with depencides containing binaries (e.g.…

    openai-realtime-embedded-SDK Build AI assistants on microcontrollers▲63

    Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.…

    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.…
