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 ...

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 ...

In the 21 st century, it is all too easy to take today’s powerful microcomputers for granted, and as artificial intelligence continues to make inroads, the assumption is that massive amounts of data ...

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 ...

On this 60 th anniversary of the first issue of EDN, we look back to 1956 when the vacuum tube was at its maturity and transistors were about to begin their domination. The vacuum tube features of ...

Prior to Bell Labs’ first working transistor in 1947, which ushered in the advent of semiconductor technology and the computer age, every long-distance telephone call, radio and television broadcast, ...
