Ralph Merkle, Robert Freitas and others have a theoretical design for a molecular mechanical computer that would be 100 billion times more energy efficient than the most energy efficient conventional ...

A steel bar pivots. A spring stretches. Then, with a small shove, the whole setup flips into a new state and stays there until the next push. “We typically think of memory as something in a computer ...

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 ...

Mechanical keyboards can turn typing into a premium experience, but picking the right one takes some care. Here are eight ...

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 ...

In the 19th century, British mathematician Charles Babbage invented the “difference engine,” a mechanical computer that had an enormously complex arrangement of levers, ratchets and gears. Had this ...

Typically, the brain of a computer is tiny and made out of silicon, buried deep inside a much larger gadget with control mechanisms like a keyboard or a touchscreen. But it doesn't have to be that way ...
