Carbon’s Domino Clock is pretty much just what it sounds like: three giant dominoes hanging on the wall and telling the time in a difficult-to-read fashion that would make Tokyo Flash proud. With a little deciphering, though, you can work out what it says. In the picture above, the clock reads 12:59 (at least I think it does).
More interesting than the aesthetics is the mechanism. The dots flop over like the numbers on those old digital flip-clocks, although instead of plastic leaves it uses a solid multi-sided block that only draws power when it is rotated. The dots use a custom actuator, with the magnet actually running around the coil. The motors were designed to flip the dots slowly enough to give a sense of heft and gravity.
This adds a nice mechanical touch and makes things exciting when all the numbers cascade at once, although it runs in deathly silence, and will run on batteries for a couple years, which is impressive given the size.
Sadly, you can’t buy one. But you can watch this video of how it works:
