There are lots of different ways to tell the time. You can use an old school analog clock with hands, a segmented digital display, or even a sundial. But I can say with 100% certainty that this is the first clock I’ve ever seen that tells time with sequins.
Architect and tinkerer Ekaggrat Singh Kalsi put together the Sequino, a truly unique timepiece that takes advantage of the bi-colored nature of some sequins, flipping them from one side to the other to reveal the current time. The sequins are set onto a cylindrical backdrop, and then a mechanical arm moves up, down, left and right to flip the sparkly bits over with a specially engineered tip that’s designed to emulate a human fingertip. Imagine a two axis plotter set onto a curved surface, and that’s basically the mechanism. It’s driven by a pair of motors and controlled by an Arduino Nano. Check it out in action in the video below:
