Intring is an ESP32-C3-based smart interactive ring that combines a trackball, air mouse, and gesture recognition. It utilizes FreeRTOS and TensorFlow Lite Micro for on-device motion processing and communicates via BLE HID to control AR/VR headsets, PCs, and mobile devices.
Midad is an open-source firmware for Xteink e-ink devices, specifically engineered for Arabic script and right-to-left languages. Running on the ESP32-C3 platform with FreeRTOS, it provides a comprehensive e-reading experience with advanced text shaping, OTA updates, and a unique suite of integrated applications like a gym logger and Tasbih counter.
A standalone flight tracking dashboard for ESP32-S3 touchscreen devices that visualizes live ADS-B data, routes, and weather without requiring external servers or subscriptions. It utilizes the ESP-IDF framework, LVGL graphics library, and standard networking protocols to provide a rich, interactive aviation monitoring experience.
A Linux-based desktop application for managing Thermalright LCD displays and RGB LED controllers through a native Qt interface. It uses a reverse-engineered protocol to communicate with hardware via USB, supporting various metrics for CPU, GPU, and system status without requiring a root service.
RFSqueak-MK1 is a portable embedded system for RF spectrum scanning and Morse code communication, built around an ESP32 MCU and a CC1101 Sub-1GHz transceiver. It features real-time signal visualization through a color TFT display and provides a tactile interface for frequency tuning and manual Morse keying. The firmware leverages the Arduino framework and RadioLib to offer features like waterfall displays, channel occupancy monitoring, and automated Morse decoding.
A high-performance microphone solution for the M5StickS3, featuring Rust-based firmware and companion applications for macOS and iOS. It supports both plug-and-play USB Audio Class functionality and wireless streaming via WebSockets or Bluetooth LE, utilizing the ESP32-S3 and an ES8311 audio codec.
Duet is an open-source firmware for the Xteink X3 and X4 e-readers, built on the ESP32-C3 microcontroller using the Arduino framework and PlatformIO. It features a unique serverless device-to-device sync via ESP-NOW, a comprehensive reading statistics suite with 33 data pages, and a highly customizable interface supporting StarDict dictionaries and specialized E-Ink font systems.
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.
