I have always been interested in electronics engineering ingenuity used to solve “impossible” problems. One such problem was the task of deciphering the German Army's most secret transmissions during ...

In a few museums around the world, there lies the special experience of seeing some of the earliest computers. These room-filling monsters have multiple racks of vacuum tubes that are kept working by ...

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 ...

See refrigerator-esque and semi-trailer-sized models, including an early mobile computer. The Vintage Computer Festival East is a once-a-year museum exhibit in Wall, New Jersey that shows off vacuum ...

A duo-triode may be 2 Watts. So 113 tubes can be 226 Watts. OK, bias and coupling elements may push past 3 Watts per bottle, 339 Watts. I was just reading of an Intel NUC tiny-computer CPU of nominal ...

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 ...

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 ...
