In the early 1200s, Fibonacci introduced a series of numbers that now bear his name, starting with 0, then 1, and continuing on as the sum of the two preceding numbers. This gives values of 0, 1, 1, 2, 3, 5, 8, and so on, and after being prompted by a friend, “TecnoProfesor” decided to turn this numerical pattern into a clock.

The concept here is that instead of using the conventional 1-12 to display the time, this device uses blocks corresponding to Fibonacci numbers 1-5, with circular icons adding increments of 12 for minute and second values. 

It’s an interesting concept, somewhat akin to the world of binary or even word clocks. The build consists of an Arduino Mega and a DS3231 RTC module for control, a wood and methacrylate housing, and a number of programmable RGB LEDs to indicate numbers.
