“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 ...

LONDON — Ideas of how to exploit miniaturized vacuum tubes have emerged regularly and without much success, since the glass-envelope valve was replaced for most applications by the transistor. However ...

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 ...

DARPA-funded researchers recently demonstrated the world’s smallest vacuum pumps. This breakthrough technology may create new national security applications for electronics and sensors that require a ...

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 ...

While most VEDs in common use today (traveling wave tubes (TWTs), klystrons, crossed-field amplifiers, magnetrons, gyrotrons and others) were invented in the first half of the 20th century, ongoing, ...

Scientists in a lab in China have developed a remarkable vacuum tube that could help make a game-changer electronic warfare device, according to a report. They developed a miniaturized traveling-wave ...
