When we talk about a “computer” today, we generally picture an electronic machine that can perform various kinds of mathematical operations, manage its program flow, move data from one place to ...

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, ...

Inside there's a coil of wire wrapped around an iron core. When a current flows through this control wire, it creates a ...

I’m Adam Conway, an Irish technology fanatic with a BSc in Computer Science and I'm XDA’s Lead Technical Editor. My Bachelor’s thesis was conducted on the viability of benchmarking the non-functional ...

For decades, the speed of transistors has been approaching its physical limit. Now, researchers have built a new type of vacuum/air channel electron tube that completely eliminates a fatal flaw that ...

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, ...

Millimeter wave vacuum tubes, including ones like the traveling wave tube (TWT) depicted here, amplify signals by exchanging kinetic energy in the electron beam (shown as a blue line) with ...

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 ...
