Open Source Real-Time Operating Systems

LuxDMX is an open-source Art-Net and sACN to DMX512 gateway designed for ESP32 and ESP32-S3 microcontrollers, featuring a live web-based diagnostic interface. It provides professional-grade lighting control with support for RDM, source merging (HTP/LTP), and multiple network interfaces including WiFi and wired Ethernet. The project utilizes a FreeRTOS-based architecture to ensure low-jitter DMX timing while simultaneously serving high-speed telemetry via WebSockets.

An Arduino Nano-based interface designed to enhance the control and safety of dual-track vehicles using inexpensive BLDC motor controllers. It replaces standard filtered PWM with a high-resolution 12-bit DAC and implements configurable drive profiles, throttle shaping, and track trim compensation.

An accessible, 3D-printed robotics platform powered by the ESP8266-based Wemos D1 Mini. It features Wi-Fi and ESP-NOW connectivity for remote control, uses continuous rotation servos for locomotion, and integrates LED matrix displays for visual feedback and sensor data visualization.

AtlasCube is a feature-rich internet radio and smart clock firmware built for the ESP32-S3 using the ESP-ADF and LVGL libraries. It supports streaming various audio formats, Bluetooth A2DP/HFP via external modules, and local SD card playback, all managed through a comprehensive on-device GUI and a standalone web interface. The project is designed for independence from cloud services, offering local MQTT control, OTA updates, and a customizable event system.

VerhoBot is an open-source smart curtain robot based on the ESP32-C3 platform, designed to automate curtain movement for improved sleep cycles. It utilizes a TB6612FNG motor driver and N20 geared DC motor to provide quiet, battery-powered operation with integrated WiFi scheduling and a web-based management dashboard.

HEARD is a mesh network system of ESP32-based devices designed to monitor hiking group safety in remote environments without cellular coverage. It utilizes LoRa for multi-hop communication and GPS for real-time location tracking against pre-loaded GPX routes, featuring a firmware-in-the-loop simulator for protocol validation.

FrameFilm is a retro-styled digital film fridge magnet featuring a 3.6-inch color E-Ink display and an ESP32-S3 microcontroller. It utilizes specialized dithering algorithms to replicate a film aesthetic and supports wireless photo transmission via BLE through a web-based management tool or a WeChat mini-program.

A custom ESP8266-based firmware for the GeekMagic SmallTV smart weather clock, featuring a 240x240 ST7789 display. It utilizes the TFT_eSPI library for rendering and LittleFS for persistent storage of configurations and authentication data. The system provides a comprehensive web dashboard for managing WiFi, OTA updates, and various data feeds including weather, markets, and Home Assistant integrations.
