The cylinders began a rhythmic, percussive cycle. It was the heartbeat of an automated factory, a miniature assembly line born from a few pages of instructions and a steady hand.

The climax came with "Signal Overlap in a Sequence Control." Two cylinders, A and B. They had to dance. A+ B+ A- B-. He wired an using two pressure switches
By the time he reached the "Logic Operations" chapter, the story grew tense. He wasn't just moving air anymore; he was teaching the machine how to "decide." He pressed the second—nothing
The air in the workshop didn’t just sit still; it held its breath.
