Accurate Split-Flap Display Can be 3D Printed
2 min read
A split-flap display uses a 28BYJ stepper motor with a magnetic encoder for precise character positioning. The flaps are fully 3D printed, enabling two-color printing on single-color printers. A Raspberry Pi Pico controls the five-character setup, with larger displays potentially needing a multiplexer.
