Simple MCP2036 SDR Radio - The Most Unusual Software Defined Radio
Pavleski Jul 30,2026
 SDR (Software Defined Radio) is a radio communication system where many of the key electronic components of a classic radio receiver, such as filters, amplifiers and detectors, are replaced by software that runs on a computer or mobile device. In several previous videos, I have presented various ways to make software defined radios, from the simplest with a single vacuum tube to SDR with a Raspberry Pi pico and two displays. Basically, they were all made in classic well-known ways. This ti...

Elecrow All-in-One Arduino Starter Kit Review - 20 Projects & 16 Modules
Pavleski Jul 24,2026
 This time I will describe a simple and practical way to enter the world of microcontrollers, specifically Arduino. Arduino is an open-source electronics platform that combines simple hardware (microcontroller boards) and software (Arduino IDE) to let anyone build interactive projects like robots, sensors, or smart devices. It’s widely used by beginners, hobbyists, and professionals because it’s affordable, easy to learn, and supported by a huge global community.  Namely, during t...

Antenna (or whatever) Selector SHIELD for Arduino Uno
YU2ZZ Jul 21,2026
This shield was designed with no particular project in mind. It aims to be useful for both automatic and keypad-operated antenna selectors in general. This is just hardware, providing slightly more than a set of ten relay drivers, but there are many projects/sketches on the Internet (including my blog) that could be easily adapted to work with it. The shield could also help build other Arduino-based devices that will switch multiple loads on and off and may have nothing to do with amateur radio....

Arduino-Based DSP Morse Decoder and Trainer
YU2ZZ Jul 21,2026
This real-time real-world Morse decoder and trainer uses the Goertzel algorithm to detect a CW tone of 708 Hz. The program then analyzes the detected tone patterns in order to recognize and decode Morse characters.A signal with a good SNR and fairly correct (not necessarily perfect) Morse code tone patterns will be decoded flawlessly; for example, a signal taken directly from a computer, or a 9+ signal over the radio. The speed can exceed 50 standard words per minute (WPM). However, human input ...

ESP32-Based Smart Sensor Node with Custom PCB Design
Lin Jul 20,2026
The original idea was to create a compact and reliable sensor platform that can be used for environmental monitoring, home automation, and remote data collection.Instead of using multiple development modules connected with jumper wires, I designed a custom PCB to integrate the controller, power supply, communication interface, and sensor connectors into one compact board.The goal of this project was not only to build a working device but also to practice the complete hardware development process...
