Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. The last major vacuum tube retirement was the long-lasting ...

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 ...

“You should have used a 555” has become a bit of a meme around these parts lately, and for good reason. There seems to be little that these ubiquitous chips can’t be used for, and in a world where ...

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 ...

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 ...

As we discussed in Part 1 of this new mega-mini-series, I was recently introduced to vacuum fluorescent displays (VFDs).

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 ...

Todd Sharp is surrounded by a mountain of guitar amps. But he’s quick to say some of them are better than others. “That’s kind of my motto here: Life is too short to play shitty amps,” he said with a ...

CRANE, Ind. – U.S. Navy radar experts are approaching industry to find alternative electronic manufacturing and materials for microwave vacuum tubes because existing materials are expensive and ...

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 ...

HoRNet has released HoRNet Valvola. Valvola is the Italian word for vacuum tube and the company says that this free plug-in is an emulation of the electric behavior of a vacuum tube and its ...

PROF. L. B. ARGUIMBAU'S title is perhaps more suitable for one of those gloomy, but useful, volumes cataloguing every conceivable circuit in which valves have ever been used or misused, for he has ...
