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 ...

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 ...

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels. Their ...

The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...

Researchers have developed a vacuum tube prototype that is both fast and tough against radiation, making it ideal for computers in space. Researchers have developed a vacuum tube prototype that is ...

A travelling wave tube shows how far vacuum electronics has come. Mention vacuum tubes and some people (those old enough and/or historically minded) might think of ENIAC, the first electronic digital ...
