Discover the best Open Source RTOS solutions for embedded systems and IoT devices
Claude Buddy Pico is a hardware mascot for Claude Desktop, ported from the original M5Stack version to the Raspberry Pi Pico 2 W. It features a 2.8-inch landscape display, Bluetooth Low Energy connectivity via BTstack, and physical buttons for approving or denying AI tool calls. The project utilizes the Pimoroni Pico library for peripheral management and includes custom 3D-printable CAD files for the enclosure.
An expressive AI desk companion based on the Seeed Xiao ESP32-S3 that features a fully animated face system. It utilizes the ESP-IDF framework with FreeRTOS, LVGL for rendering display interfaces, and SPIFFS for asset storage. The project integrates I2S audio components for listening and speaking capabilities, creating a dynamic interactive experience.
A custom bootloader for the ESP32 that enables switching between multiple firmware versions using hardware switches. It integrates Over-The-Air (OTA) update capabilities and the ESP-Serial-Flasher library to facilitate remote firmware management and master-slave device flashing.
A real-time monitoring tool for Claude Code usage, designed for the ESP32-2432S028R (CYD) hardware. The project uses a Go-based daemon to track Anthropic API rate limits and displays animated pixel art sprites that react to the user's coding activity.
An open-source watch operating system designed for ESP32-S3 microcontrollers, specifically targeting the LILYGO T-QT Pro. It provides a customizable environment for watch faces and applications, utilizing the TFT_eSPI library for display management and FreeRTOS for task handling. The system includes features like WiFi time synchronization, motion sensing via MPU6050, and integrated games.
An embedded controller for the KompressorKlock project, built on the STM32G071G8Ux microcontroller. It manages user input via a rotary encoder and controls peripheral hardware using I2C and PWM signals. The system is developed using the STM32Cube G0 firmware package and standard HAL drivers.
A custom-built 6-digit clock utilizing Soviet-era IV-11 vacuum fluorescent display tubes and an Arduino Nano Every. The project features a static drive architecture for maximum brightness, integrated power conversion for high-voltage rails, and a robust finite state machine for user configuration and timekeeping.
M5_Crystal is a modular firmware for M5Stack devices like the M5StickCPlus2 and Cardputer, providing a suite of tools for Wi-Fi, NFC, and Bluetooth interaction. It utilizes the M5Unified and M5GFX libraries for hardware abstraction and is built on a custom wrapper system designed for rapid feature development.
