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.
