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 (W… ...

They use addition to emulate other mathematical operations in long-winded, roundabout ways. ... If you're curious about binary and logic gates and how they become a computer, ...

By chaining these gates together, Mould successfully constructs a system that can add 4-digit binary numbers, showcasing the versatility and universality of logic gate principles.
