When talking about computers based on vacuum tubes, and not referring to the machines from the 1950s, only one name immediately comes to mind: @UsagiElectric.

The level of craziness combined with a profound fundamental knowledge of computing machines based on electric currents is simply an unbeatable combination. If you're not yet familiar with his YouTube channel, it's definitely worth checking out the list of available videos.

But whether you're already a fan or about to become one, it doesn't really matter, because one of the latest videos titled A Vacuum Tube Single Board Computer once again exceeds all expectations one might have just from the title. Why?

Because the device uses just 24 tubes and, while not Turing complete, it executes 1-bit ALU operations in an extremely clever way. Those who are into CPU design will find real joy in this, and for everyone else, there's not just highly informative content but also some really beautiful visuals to enjoy.

Happy watching. 📺
