The earliest all-electronic computers used vacuum tubes, and most of us will know about machines such as ENIAC or Colossus.

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 ...

The project, called The Tube Computer MK3, was built by Mike, a self-taught electronics tinkerer who recently documented the ...

A self-taught electronics tinkerer called Mike recently shared details of his retro-computing vacuum tube computer project.

More recently, I was introduced to vacuum fluorescent displays (VFDs). These tubes aren’t manufactured anymore, but they are ...

In this edition of PowerBites, developments range from silicon vacuum tubes and rapid prototyping kits to Li-ion-battery-pack-targeted MOSFETs and an eye-popping electric motorcycle. Diamond-based ...

Talking about vacuum tubes—or “vacuum electron devices” (VEDs), as their proponents prefer to call them—may seem like you are discussing ancient history. After all, who even considers VEDs when ...

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 ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Vacuum tubes are specialized light ...

The earliest all-electronic computers used vacuum tubes, and most of us will know about machines such as ENIAC or Colossus. Vast machines that required the budget of a country at war to build, andfill ...
