We’ve been seeing a lot of metaclocks lately — a digital clock whose display is formed by the sweeping hands of an array of individual analog clocks. They can look fantastic, and we’ve certainly seen some great examples.
But in this time of supply pinches, it’s not always possible to gather the parts one needs for a full-scale build. Happily, that didn’t stop [Erich Styger] from executing this circular multi-metaclock with only thirteen of his custom dual-shaft stepper analog movements. Normally, his clocks use double that number of movements, which he arranges in a matrix so that the hands can be positioned to form virtual seven-segment displays. By arranging the movements in a circle, the light-pipe hands can mimic an analog clock face, or perform any of [Erich]’s signature “intermezzo” animations, each of which is graceful and engaging to watch. Check out a little of what this charmingly recursive clock has to offer in the video below.
[Erich] could easily have gotten stuck on the original design — he’s been at this metaclock game for a while, after all. The fact that the reduced part count forced him to get creative on the display is the best part of this build, at least to us.
