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.

In this project, I convert a classic PCL86 single-ended tube amplifier design to operate with the less common PCL82 vacuum tube. Powered entirely from compact DC-DC converters, this amplifier delivers maximum 2W of warm tube sound with absolutely no audible hum or switching noise.

In this project I demonstrate an extremely simple Direct Conversion SDR Receiver based on the Microchip MCP2036 IC.

This Elecrow Starter Kit saves time, eliminates wiring problems, and makes learning electronics both simple and enjoyable.

This ESP32-C3 Color Detector demonstrates how accurate and efficient color recognition can be achieved using a dedicated TCS34725 optical sensor. With real-time RGB detection, instant LED feedback, and a wireless smartphone interface, the project provides a practical and low-cost solution for a wide range of embedded electronics applications.

How to build a highly reliable, automated Flood Protection System using an ESP32 microcontroller and a Telegram Bot for real-time remote monitoring and control.

It uses free API key with Live ADS-B data, presented in a beautiful visual display with smooth animation, and a custom-built radar interface.

After a simple calibration process, the laser beam points extremely close to the desired target, making it possible to find many deep-sky objects within seconds using binoculars or a telescope.

The project successfully demonstrates the integration of graphical user interfaces, I2C sensors, and the ESP32-S3 microcontroller into a compact avionics instrument simulator.

A simple rectifier tube can produce high-quality X-ray radiographs. It is a cost-effective way to explore the principles of medical imaging and vacuum tube physics in a controlled DIY environment.

This project demonstrates a simple yet highly effective SDR (Software Defined Radio) receiver based on a dual-conversion superheterodyne architecture using two NE612 mixer ICs.
