YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

Oscillators, also called astable multivibrators, are electronic devices that generate a periodic signal. They are employed in a large number of applications such as clocks, oscillophones, musical ...

It may seem a paradox, but in the future tiny computers may dump electronics and return to their mechanical roots. At the macroscale, mechanical computers are fussy and slow, but when your area is ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate. Cancer cells ...
