NocKinematics is a modern, modular, and lightweight C++ Inverse Kinematics library designed specifically for Arduino and ESP32 microcontrollers. It utilizes the FABRIK (Forward And Backward Reaching Inverse Kinematics) algorithm to provide fast, iterative computations that are more efficient than traditional Jacobian Matrix approaches. The library is optimized for memory-constrained systems like AVR and ESP8266 by using specialized dynamic memory allocation to prevent RAM fragmentation.
Key features and topics:
* N-Joint Support for arbitrary numbers of connected joints.
* Memory-optimized architecture avoiding heavy std::vector usage.
* Platform agnostic compatibility with Arduino Uno, Nano, Mega, ESP8266, and ESP32.
* Practical implementation examples ranging from basic logic verification to multi-DOF servo motor control.
* Support for complex mechanisms like snake or tentacle simulations via the MultiJointSnake example.

This project details how to serve offline content (Wikipedia, etc.) from an ESP32 microcontroller, specifically using a LILYGO T-Dongle-S3. It covers the process from downloading ZIM files, processing them with Python scripts, transferring to an SD card, and loading a sketch onto the microcontroller to serve the content via a WiFi access point.
Instalator for ESP32 DataDisplay V1 project. Contains files for flashing and running the project on an ESP32.
Arduino code for an OLED flight display. This project uses an ESP32 to query the adsb.lol API for nearby flights and display the information on an OLED screen.
ESP MQTT client and broker library. This is a lightweight and easy to use MQTT library for ESP8266 and ESP32 devices. It supports client and broker modes, MQTT 3.1.1, arbitrary sized messages, and integrates with ArduinoJson.
This GitHub repository showcases various projects and designs for the Lilygo T-Display S3 ESP32 board. It includes examples like clocks (Strawberry, Casio-style, Nixie, Moon Phase), calculators, dashboards (Home Automation, PV Energy Monitor), and other creative UIs. The repository provides code and resources for building these projects, often utilizing Squareline Studio and LVGL. It also links to YouTube tutorials for each project.
