Electromagnetic Flip Digit Display
A hardware experiment using electromagnetic actuation to create a compact, high-contrast flip-digit display.
Problem / context
Mechanical displays are often visually robust and readable, but they can be hard to drive reliably at small scale. This project explored whether a lightweight electromagnetic architecture could produce crisp, repeatable digit flipping behavior.
Approach
The build focused on actuator geometry, pulse behavior, and practical packaging. The implementation prioritized clear state transitions, straightforward control logic, and iterative tuning of physical tolerances.
Outcome / lessons
The prototype validated the concept and highlighted the importance of balancing electromagnetic force margins with mechanical friction and alignment tolerance. A key takeaway was that integration details dominate performance in small electromechanical systems.
