A travelling wave tube shows how far vacuum electronics has come. Mention vacuum tubes and some people (those old enough and/or historically minded) might think of ENIAC, the first electronic digital ...

Moore’s Law is under threat. In the battle between chip designers and the laws of physics, it’s beginning to look like it won’t be long before it’s impossible to double the number of transistors on ...

The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...

There you are at the surplus store, staring into the bin of faded orange, yellow, red, and black, boxes–a treasure trove of vintage vacuum tubes—dreaming about building a tube amp for your guitar or a ...

Rossville, Georgia, on the border with Tennessee, doesn’t look like a tech town. It’s the kind of place where homey restaurants promising succulent fried chicken and sweet tea are tucked among ...

LOS ANGELES (CBSNewYork/AP)-- Imagine traveling from Manhattan to Beijing in two hours. A couple of innovative minds believe they know how to cut travel time drastically, using high-speed capsules ...

“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 ...

Since the invention of microelectronic devices like transistors and the integrated circuit in the 1940s and ’50s, semiconductors have been the backbone of electronics. However, current microelectronic ...

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 ...

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 ...

The video explains the operation of the vacuum tube, specifically the triode, which is essential in modern communication devices like radios and telephones. It describes how a tungsten filament emits ...
