Using Pulleys And Weights To Explain Binary Logic Gates

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) ...

Memristors combine memory, logics set in one device

Memristors, a type of circuit element based on magnetic flux, were first proposed back in 1971, but remained limited to the realm of theory until 2008. That’s when some researchers from HP Labs ...
