Tired of reading the same boring clock all over again? Try this one! I guarantee that you will break a sweat while reading it (at least in the learning phase)…

Fibonacci clock is a clock based on the Fibonacci sequence (wiki).

How to read this clock? Just look at the pictures with explanation and examples.

Print:

0.2 layers, no supports needed

print the back and body parts in darker color

print the front in white color

BOM:

Wemos D1 mini (or similar, ESP8266 based) board, or ESP32 based board

12 individually addressable 5V LED's (I used RGB LED strip)

5V power source

Power connector (optional - you can power it up directly via USB)

About the source code:

• Once uploaded, you will have a new WiFi available (default name is “FibonacciClock” without password). Connect to that WiFi and it will show you WiFi manager through which you can connect to your own WiFi network. Once connected, give it a minute to synchronise and you should be all set.
• As seen on the pictures, the clock displays time down to 5minutes precision (so while displaying time e.g. 3:25, the actual time could be somewhere between 3:25 to 3:29)
• There are several different ways to display one specific time, so there is a random function that will change the colors (almost) every minute while displaying the same time.
• Number of leds corresponds to the number on the clock.

Wiring:

RGB → Wemos D1

5V → 5V

GND → GND

Data pin → D4 (or 4 on the ESP32)

(sequence of the leds from wemos to the end the led strip is from the 1 square to the 5 square. So 1 → 1 –> 2 → 3 → 5
