This paper shows how to build a computer consisting of a few mechanical elements. Two large gears are needed, one for the data, and another for the program memory. Only one logical computing element is required. The idea of a simple computer with minimal computing logic goes back to Konrad Zuse, who called it the “logic machine”. Charles Babbage was the first one to design a universal mechanical computer. Here, we combine Babbage’s gears and wooden pegs with Zuse’s idea.
