Alex Gorischek baut einen Computer (Logic Gates) mit ein paar Gewichten, Schnüren, Nägeln und Krams gebaut. Nice!
The essence of digital computing is the use of continuous physical states to represent a discrete number of symbols and the ability to perform logic based on those symbols. Although electronic circuits are exceptionally well-suited for this, any system that can handle symbols as both input and output is a digital computer. Here, I've demonstrated the construction of simple digital computers (specifically, binary logic gates) using pulleys and weights.
