This intricate redstone contraption is a marvel of engineering, designed to perform addition automatically. Its complex network of circuits, dispensers, and observers demonstrates a sophisticated understanding of Minecraft's redstone mechanics. The build is presented from multiple angles, showcasing its compact design and functional layout on a flat grassy plane.

Build Details
Adds numbers (binary) (lever on is 1, no matter the position). You can link together multiple for larger number outputs. 1 adder is 4 possible digits (0-3), 2 adders is 8 digits (0-7) and so on. To link adders, destroy the lever on the orange wool on your second machine and redstone lamp with light gray wool on your first one and connect them via redstone. I built this from the logic gate map on page 370 of How To Invent Everything by Ryan North.
