Seven-Segment Display

By Ben Everard. Posted

Electromechanical seven-segment displays look amazing, but not everyone is in love with the click-clack sounds they make. David McDaid decided to solve this problem by getting rid of servos and replacing them with stepper motors.

In his own words: “The goal here was two-fold; create something stylish that would look good when hung up on a wall, and ensure that all movements were as quiet as possible! I was inspired by some great existing projects, but most had used noisy servos. Using my idea to retrofit silent stepper drivers from 3D printers, I built, tested, and coded my clock completely from scratch over two to three months of my spare time.”
