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 ...

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 ...

Fiio's EA13 is a tube amplifier that's surprisingly affordable ...

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 ...

For most of us, electronic technology comes in the form of solid state devices. Transistors, integrated circuits, microcontrollers. But for the first sixty years or so of the field existing, these ...

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

In the 21st 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 ...

The Western Electric 91E Integrated Amplifier, a category winner in the Robb Report 2023 Audio Awards, has made quite a stir since its recent introduction, and for a host of reasons. Just a single ...

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 ...
