Discover the best Open Source RTOS solutions for embedded systems and IoT devices
This project implements a 4-wheel drive robotic platform controlled wirelessly via Bluetooth from a mobile device. It utilizes an Arduino microcontroller, an L298N motor driver, and an HC-05 module to enable real-time steering and PWM-based speed control. The system is designed as an open-source educational tool for learning hardware assembly, wireless communication, and embedded programming.
This project provides local voice assistant firmware for the ESP32-P4 platform, built natively on ESP-IDF and integrated with Home Assistant's Assist pipeline. It utilizes WakeNet9 for wake-word detection, MQTT for control and discovery, and features a local MP3 player and web-based management dashboard.
A high-efficiency, low-power environmental monitoring firmware developed using the native ESP-IDF v5.x framework for the ESP32-C3. It integrates deep sleep cycles with multi-sensor data collection and provides configurable alerts via Telegram, Discord, and custom webhooks. The system includes a built-in SoftAP web portal for runtime configuration, allowing users to manage Wi-Fi credentials and sensor thresholds without serial re-flashing.
A retro-styled desktop companion for ESP32-C3 and ESP8266 that monitors AI coding assistant usage, stock markets, and system telemetry. It leverages the Arduino framework with TFT_eSPI and AnimatedGIF libraries to display real-time data provided by a local bridge application.
SensorStation3 is an ESP32-based environmental monitoring station that utilizes FreeRTOS and the LVGL graphics library to provide a real-time touchscreen dashboard. It supports a variety of I2C sensors for tracking temperature, humidity, CO2, and atmospheric pressure, featuring seamless integration with Home Assistant and MQTT-based platforms.
An open-source, 3D-printable 6-DOF navigation controller designed for CAD applications and slicers. Built around an Arduino Pro Micro and four JH16 Hall-effect joysticks, it provides native USB HID 3D-controller input and an optional mouse-emulation mode. The project features adjustable speed profiles, configurable dead zones, and multi-axis input filtering for precise 3D manipulation.
GeoShake is an open-source firmware and hardware project for a distributed, real-time earthquake monitoring station based on the ESP32-S3. It utilizes high-precision accelerometers and on-device seismic processing to contribute to a global seismic network via MQTT and BLE connectivity.
BubblePager is a dedicated hardware pager for Telegram that displays video notes, stickers, and text on a round GC9A01 display. Built on the ESP32-S3 platform using the LVGL graphics library and FreeRTOS, it communicates with a self-hosted FastAPI server that transcodes media into MJPEG streams. The system features a custom unread queue, touch/button navigation, and motion-wake capabilities.
