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 ...

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 combined both ...

A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...

Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. Vacuum tubes disappeared from electronic products years ago.

The project was designed using 6T9 vacuum tubes to build an amplifier device that operates in Ultra-Linear (UL) mode. The tube amplifier circuit works better in Ultra-Linear mode which used to operate ...

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 ...

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 ...

Nothingness might not sound very useful. In fact, the opposite is the case because nothingness – in the form of a vacuum – has played a major role in the history of electronics. Until the invention of ...

Vacuum contains nothing to interrupt charge flow, making it an ideal medium for electron conduction. Whereas charge flowing through a semiconducting channel will usually scatter, causing power loss ...
