Vintage Plasma Display Reveals Current Radiation Levels
A hobbyist named Alex has built a stylish radiation level monitor using an ESP32 microcontroller and a vintage Soviet-era plasma display, inspired by Chernobyl's exclusion zone. The device fetches sensor data via an API and includes a Geiger counter, with the display operated as a text-only matrix that can be modified for additional symbols. This project highlights the charm of vintage displays and their potential for reverse-engineering and modern applications.
