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

Learn how to make a simple device for monitoring the state of the ionosphere and the quality of shortwave signals using the CA3089 chip.

By integrating advanced sensors and optimizing the power management of the ESP32, I've created a DIY smart lock that is both reliable and energy-efficient.

This ECC83 (12AX7) preamplifier project successfully delivers the warm, pleasant, and dynamic sound characteristic of vacuum tubes.

The system displays real-time weather data including radar maps, cloud coverage, rain intensity, and detailed multi-day forecasts with interactive graphs.

The AD9850-based VFO provides a clean, sine-wave alternative to square-wave oscillators, ensuring your HF receiver remains free from unwanted harmonic inThe AD9850-based VFO provides a clean, sine-wave alternative to square-wave oscillators, ensuring your HF receiver remains free from unwanted harmonic interference.
