It all began with a cheap Chinese rotary vane vacuum pump and a desire to learn the witchcraft of DIY vacuum tubes. It ended with a string of successes – a working vacuum chamber, light bulbs, glow ...

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 ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future. As part of a new program, the agency is ...

Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a ...

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 ...

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 ...

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 ...

Retro technology makes a comeback in a nanoscale transistor that is lightweight, low cost, and long lasting. Vacuum tubes have been retro for decades. They almost completely disappeared from the ...
