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.

With this project, you can easily turn your old (or new), useless TV into a beautiful retro video effect device.

DIY Tesla Coil based Plasma Rife Machine

In this project, I built a fully functional analog-style VU meter using an CrowPanel 3.5"-HMI ESP32 display, and LVGL.

A professional-looking VFO for your radio projects without spending a fortune on touchscreen, rotary encoder or complex hardware.
