A Computer Built With Dominos

By arranging enough dominos into just the right structure, we can build a computer. But how do we arrange dominos in such a way that they can perform computation? Here, we explore the process of building domino logical circuits by carefully arranging dominos into configurations that can compute logical functions. 0:00 A Domino Computer 0:56 OR 1:39 XOR 2:47 AND 4:30 Half Adder 6:06 Full Adder 7:20 The Circuit I first saw this concept in Matt Parker’s 10,000 Domino Computer ( which I’d absolutely recommend watching: computer simulations make for great visualizations, but building the physical domino circuit is an entirely different type of impressive. *** Spanning Tree is an educational video series about computer science and mathematics.
