[Mr Carlson] serves up another vintage offering, this time in the form of a tube op amp. The K2-W model he acquired enjoyed popularity when it was released as one of the first modular general purp ...

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 ...

The transistors of the future could make modern chips seem as big and bulky as vacuum tubes seem to us today. The problem is that once devices become that tiny, everything moves according to the ...

A vacuum tube is just that: a glass tube surrounding ... This kind of thinking would be as important as science for the invention of the transistor. Edison's discovery that current can travel ...

It proved that transistors could replace bulky vacuum tubes, paving the way for smaller, more energy-efficient devices like the TV8-301. Panasonic TR-005 Orbitel (1970s) – A later development in ...

Scientists in the US built the first silicon transistor in 1947. Before that, the mechanics of computing had been performed by vacuum tubes, which were slow and bulky. Silicon changed everything.

Hyperloop startup Arrivo's plans for super-speedy transportation have finally arrived with an ambitious new system for Denver, Colorado — but don't expect to see any of the bulky vacuum tubes ...
