Making A Neo Nuvistor Project In 2026

A hobbyist known as TubeTimeUS built a discrete 555-style timer using eight tetrode nuvistors, a type of miniature vacuum tube from 1959 once used in radios, TVs, and Ranger Moon probes. The build required extra pins to power the heater elements, consuming about 7.5 watts, but nuvistors retain advantages over transistors such as strong immunity to electrostatic discharge, electromagnetic interference, and even EMPs that would destroy typical semiconductor electronics.
