Modern digital computers have complex instruction sets that runs on state-of-the-art ALUs which in turn are a consequence of miniaturized logic gates that are built with tiny transistors. These tiny ...

We’ve seen our share of blinking light projects around here; most are fairly straightforward small projects, but this entry to the 2025 One Hertz Challenge is the polar opposite of that approach.

This mini-series of articles describes how to build a computer’s CPU (central processing unit) out of relays. “Y” in English sounds like “guay” in Spanish (my mother tongue), a colloquial expression ...

Traditional relay drivers involve multiple discrete components to drive the relay and protect against damage to the microcontroller or other devices that can be caused by the voltage spike generated ...
