The vacuum tubes used as power amplifiers in microwave systems may be on their way out following the development by a research team from US-based Agere Systems of a solid-state microtriode that can be ...

We’ve all seen electronic components that have been coaxed into releasing their small amount of Magic Smoke, which of course is what makes the thing work in the first place. But back in the old times, ...

One of the topics we've covered multiple times at ExtremeTech is the difficulty of continuing to scale semiconductor technology, and the related problem of improving chip performance without ...

And now a page from our "Sunday Morning" Almanac: November 16th, 1904, 110 years ago today . . . the birthday of an invention heard 'round the world. For that was the day the British inventor John ...

EASTHAMPTON — In a world ruled by the microchip, David Mell’s customers at Viva Tubes crave the soft electric hum and warm audio tone of the old-fashioned analog vacuum tube. Tubes — simple devices ...

Remember those old-timey room-sized vacuum-tube-powered computers with less processing power than your smartphone? That tech might be making a comeback, thanks to work from scientists from UC San ...

Although we do often see projects that take antiques and replace some or all of their components with modern equipment, we can also sympathize with the view that (when possible and practical) certain ...

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 ...

In the 1800s, when pneumatic tubes shot telegrams and small items all around buildings and sometimes small cities, the future of mass transit seemed clear: we'd be firing people around through these ...
