Ladies and gentlemen, boys and girls, geeks of all ages… I present to you the Base4 Clock! Just as geeky and hackable as the Fibonacci Clock, but even more precise than its big sister.

How Do I Tell Time On The Base4 Clock?

Normally, we represent numbers using the base-10 system. As its name suggests, the Base4 Clock uses the base-4, or quaternary, numeral system to display time. This system uses the digits 0, 1, 2, and 3 to represent real numbers.

To convert to base-10 values, refer to the diagram below. The base-10 number is the sum of the values in the illuminated cells.

The Base4 clock uses the same colour schemes as its big sister the Fibonacci Clock:

  • The hours are displayed in red
  • The minutes are displayed in green.
  • When a cell is used to display both the hours and minutes, it turns blue.
  • White squares are ignored.

Open Source

The Base4 Clock is open source and will be published under the GPL license. Once all the rewards are fulfilled, I will release the source code, the schematics and the enclosure plans to the general public.

The Base4 Clock’s PCB is made to be fully hackable. You can upload your version of the clock code with no need for a development board. The clock code runs on an Atmega328P running the Arduino bootloader.


The Base4 Clock has been successfully funded on Kickstarter:
