Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic ...

Shadowman39, a K'nex enthusiast who posts to YouTube and Instructables has built a fully mechanical 8-bit computer using K'nex parts. The computer uses a simple architecture and will load programs ...

More than two millennia ago, Greek craftsmen built a bronze machine that could track the heavens with a precision that would not be matched for centuries. Hidden inside a corroded lump recovered from ...

It can be surprisingly hard to find decent analogies when you’re teaching electronics basics. The water flow analogy, for instance, is decent for explaining Ohm’s law, but it breaks down pretty soon ...

Back in the 70’s when computers were fairly expensive and out of reach for most people, [David Hagelbarger] of Bell Laboratories designed CARDIAC: CARDboard Illustrative Aid to Computation. CARDIAC ...

A single-celled organism that walks using 14 “legs” seems to control these legs with a mechanical computer made of fibres called microtubules. The finding might help explain how many other ...
