This DIY domino clock tells the time using three LED-lit tiles
After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own.
The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.
The unique timepiece is made out of cut MDF, acrylic, and 3D-printed outer sections. Everything is controlled by an Arduino Nano, along with a DS1307 RTC unit for accurate timekeeping.
Code, CAD files, and build instructions can be found in the project’s write-up.

I love the simple Domino design – very classy!
Your led version is a worthy addition.
I’d love to have a stab at doing it myself – maybe it’s time I bought myself a 3D printer
