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 ...

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

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 ...

The telephone company had problems with vacuum tubes, too, and hoped to find something ... followed quickly by transistor radios. The computer industry immediately began designing computers ...

While the first computers were mechanical and famously ran on vacuum tubes, there were other schools of thought that introduced a different kind of computer – one that ran on water. In the 1930s ...

Google's head of quantum thinks we could get real-world applications of quantum computing in just five years, while Nvidia claims it's more like 20.

There are a couple of reasons I suspect it's taken this long to see a vacuum tube in a pair of headphones. Tubes are hungry beasts, with higher power draws than other methods of amplification. They ...

(UNIVersal Automatic Computer) The first mass produced and commercially successful computer, introduced in 1951 by Remington Rand. Over 40 systems were sold. Comprising some 5,000 vacuum tubes and ...

Culminating a year-long project, [Usagi Electric] aka [David] has just wrapped up his single-bit vacuum tube computer. It is based on the Motorola MC14500 1-bit industrial controller, but since ...
