ALMANAC: Vacuum tubes 01:21. 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.

When most people think about vacuum cleaners, the brands that tend to come to mind are Dyson or Shark. But one vacuum cleaner ...

Some of you may remember a recent project that featured on these pages, a 555 timer reproduced using vacuum tubes. Its creator [Usagi Electric] was left at loose ends while waiting for a fresh PCB … ...

This means that given the resolution of the tube or the image projected onto the tube is not higher than the stripe filter (to allow all 3 colour stripes to be over a “pixel” of the same value ...

Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.

The next step for the group is to scale down the vacuum tubes and explore their many applications. If their research pans out, the computers of the future may be using technology from a century ...

This image shows an ultrahigh vacuum chamber and the surrounding systems used to prepare and analyze the surfaces of materials at Yale University. The central part is a unique combined scanning ...

Unlike the tubes of old, however, NASA's vacuum-channel transistors measure the gap between electrodes, not in millimeters but in nanometers. Making them nanoscale has a couple of key advantages.
