A specialized port of the ESP32 Marauder firmware for the ESP32-3248S035C development board, featuring a 3.5-inch capacitive touchscreen. It provides mobile tools for Wi-Fi security auditing, network scanning, and wardriving, leveraging FreeRTOS and the Arduino framework for efficient hardware management.
A sophisticated physical chess board utilizing Hall effect sensors for piece detection and dual displays for game status and clock. It runs on Go-powered Raspberry Pi or Orange Pi hardware, featuring deep Lichess integration, local Stockfish analysis, and a custom DietPi-based OS image with power-loss protection.
A high-performance VGA controller built around the 8-bit PIC18F47K42 microcontroller, capable of 360x480 resolution with 16 colors. It utilizes hardware peripherals like DMA, PWM, and SPI to generate signals with minimal CPU overhead, accepting ANSI-style escape sequences over a UART interface.
Paper Pi is a modular, asynchronous dashboard designed for Waveshare E-Ink displays, built with Python 3.14+. It targets Raspberry Pi and other Linux-based boards, providing a variety of widgets such as GitHub stats, weather, and HackerNews with support for 4-level grayscale rendering.
This project provides pre-compiled Tasmota firmware binaries specifically optimized for smart meter reading via SML and advanced scripting on ESP32 and ESP8266 platforms. It features a dual-track approach offering both the classic Tasmota Scripter and the high-performance TinyC VM, utilizing FreeRTOS for background processing and LittleFS for filesystem management. The firmware supports energy monitoring, Google Charts visualization, and emulation of smart battery interfaces like Shelly Pro 3EM.
PaperSat is a standalone satellite tracking application for the M5Paper S3 e-ink tablet, providing real-time orbital predictions and polar sky plots. It utilizes SGP4 propagation for high-accuracy tracking and features an offline-first design with LittleFS for TLE data caching. The project is designed for amateur radio operators and observers, offering on-device configuration for location and time.
An ESP8266-based IoT solution for remote management of the Logitech Z906 5.1 surround sound system. It provides a web interface and MQTT integration for volume control, input switching, and status monitoring via the system's DE-15 console port.
Pixel Pets is an open-source virtual pet ecosystem built for the M5Stack hardware family, featuring interactive digital companions with adaptive behaviors. It utilizes FreeRTOS for task management and the M5Unified library for hardware abstraction, supporting advanced features like ESP-NOW inter-device communication, offline LLM-based voice control, and real-time environment syncing.
