This project transforms the myCobot 280 into a smooth real-time 2D face-tracking robot using Python, MediaPipe, OpenCV, and Arduino.

Combining a Raspberry Pi base station with a standalone M9 terminal creates a robust, independent LoRa mesh network that keeps you connected anywhere, completely off-grid.

CrowPanel 2.1-inch ESP32-S3 display can be transformed into a compact, intuitive, and highly practical universal timer with both visual and audible indication.

With a low-cost ESP32 and WM8960, we built a complete real-time stereo parametric EQ with professional-style controls

This experiment clearly shows how much the enclosure can influence the sound of even a tiny and inexpensive full-range driver.

This is a simple multifunctional device that, thanks to the high precision of the generated frequencies (with two decimal places), can successfully emulate almost all known therapeutic devices for frequency treatment.

The CrowPanel 3.5" ESP32 proves to be an incredibly versatile platform for high-speed audio visualization. By combining custom FFT logic with the optimized TFT_eSPI library, I’ve created a audio analyzer with impressive visual effect.

A unique combination of astronomy, embedded programming and ambient lighting that transforms an ESP32-powered display into a realistic real-time Moon simulator.

These amplifiers prove that a well-designed and carefully built analog circuit can survive decades of hard use and still perform reliably.

Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN by combining long range, low power consumption, and enough bandwidth for real-time video streaming. It is a promising technology for the next generation of IoT and smart surveillance systems.

This project demonstrates that practical object recognition does not always require complex machine learning frameworks. Using only the built-in camera, display, and processing power of the UNIHIKER K10, it is possible to create a simple, fast, and effective object recognition system that can be trained directly by the user.
