This DIY HF antenna preselector drastically improves the listening experience on your shortwave radio, especially with a long wire antenna.

This simple Static Charge Monitor uses a parallel-plate detector and TL071 op-amp circuit to measure electrostatic fields, with real-time visualization via Arduino and PC software.

This is a great small portable radio. You probably can't find a cheaper radio on the market than this with similar features.

This simple oscilloscope clock is fully functional, highly adjustable, and has the option of automatically setting the time via the Internet.

This is a modern digital interpretation of a traditional barograph that displays real-time atmospheric pressure trends over a 24-hour period using a high-precision BME280 sensor and ESP32 microcontroller.

This project demonstrates the incredible potential of software-defined radio, transforming a few simple components into a powerful and flexible communication tool.
