The DIY YAESU Rotator Controller (G1000DXC version) has withstood the test during the recently concluded 2025 CQWW SSB contest.One aspect is the hardware test.This version uses a 12V-5V DC-DC converter, and the power supply for the Arduino board is also 12V, relying solely on natural cooling without forced cooling. It has been running continuously for … Read more
A small but remarkable component in modern smart devices is the geomagnetic sensor, also known as an electronic compass. Whenever we use mobile maps, that “digital pointer” that always points north relies on it. In this article, we will explore the principles of geomagnetic sensors, the secrets of their integration with inertial sensors, and their … Read more
