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 ...

There’s a Blue Bendix in Texas, and thanks to [Usagi Electric] it’s the oldest operating computer in North America. The Bendix G-15, a vacuum tube computer originally released in 1956, is now booting, ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This glass vacuum tube has one a ...

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 ...

Putting vacuum tubes in a PC might sound a little like adding a hand crank to a Porsche, but at least one company thinks it might be the future of computer audio. Taiwanese components company AOpen, ...

Linear, small-signal AC models can be useful in the analysis and design of vacuum-tube-based circuits. Under large-signal conditions, nonlinear models are typically required. Almost 120 years ago, ...
