We have occasionally featured vacuum tube computers here at Hackaday and we’ve brought you many single board computers, but until now it’s probable we haven’t brought you a machine that combined both ...

Did you know that the first half of the 20th century was dominated by vacuum tubes? Be it radio, television, telephone networks or computers, vacuum tubes were the basic component for all electronics.

Op amps. Often the first thing that many learn about when beginning the journey into analog electronics, they’re used in countless ways in an overwhelmingly large array of circuits. When we think ...

For decades, computer components have been getting smaller, even as their capabilities have grown by leaps and bounds. However, this process has started to slow down over the last few years — and it ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

Before transistors or microchips, the earliest computers relied on vacuum tubes — glass bulbs that glowed like small light ...

Scientists in a lab in China have developed a remarkable vacuum tube that could help make a game-changer electronic warfare device, according to a report. They developed a miniaturized traveling-wave ...
