Join us on Wednesday, December 9th at noon Pacific for the Vacuum Tube Logic Hack Chat with David Lovett! For most of us, circuits based on vacuum tubes are remnants of a technological history that is ...

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 [David ...

A vacuum channel transistor controls electrons at the cathode to suppress gate leakage, letting it work inside amplifiers and NAND and NOR logic gates. (Nanowerk News) A research team in China has ...

For decades, the speed of transistors has been approaching its physical limit. Now, researchers have built a new type of vacuum/air channel electron tube that completely eliminates a fatal flaw that ...
