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 ...

Vintage meets contemporary in this DAW-controllable hybrid synth that blends digital oscillators with a tube-based audio path ...

The Vacuum tube is a part of the pre-amp of the headphones, and it warms up the signal before it gets sent to your ears. It’s ...

But before even those transistor-based computers is a retrocomputing era rarely touched on: the era of programmable vacuum tube machines. [Mike] has gone back to the 1950s with this computer which ...

If you don't think B batteries exist, you're not alone. The truth is, they're real, but just a lot less common than other ...

Enormous dimensions, complicated military calculations, and thousands of vacuum tubes—this was the early supercomputer.

A vacuum tube is just that: a glass tube surrounding a vacuum (an area from which all gases have been removed). What makes it interesting is that when electrical contacts are put on the ends ...

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 ...
