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 ...

The PAL family continued to evolve into the late 1980s, with faster, lower-power devices, including ones that could be reprogrammed. The most complex device type developed was probably the PAL22V10, ...

To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (Wikipedia) ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left somewhat in the ...

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...

I've covered tons of different scientific applications you can run on your computer to do rather complex calculations, but so far, I've not really given much thought to the hardware on which this ...

Cancer cells migrate through the body for multiple reasons; some are simply following the flow of a fluid, while others are actively following specific chemical trails. So how do you determine which ...
