- Cut 4 plywood board for outside walls, 2 o … Cut 4 plywood board for outside walls, 2 others for bottom and double-bottom, and 4 littles more for inside walls to split squares. Dimensions are the following : For outside walls : * 2 boards 85mm * 221mm * 2 boards 85mm * 138mm for bottom and double-bottom : * 2 boards 128mm * 211mm for inside walls: * 1 board 50mm * 128mm * 1 board 50mm * 78mm * 1 board 50mm * 50mm * 1 board 50mm * 26mm 1 board 50mm * 50mm * 1 board 50mm * 26mm +
- Cut 4mm slots to fit together the four sides. Use a wood file for the finishing. +
- Cut the LED strip into 3 strips of 1 LED a … Cut the LED strip into 3 strips of 1 LED and 3 strips of 2 LEDS. Weld with small wires with good length, to place them into squares, as shown on the picture. Then glue the strip on the wood board of the double-bottom. Put a hole to pass wires to the other side of the double-bottom.es to the other side of the double-bottom. +
- Download Arduino IDE : https://www.arduino … Download Arduino IDE : https://www.arduino.cc/en/Main/Software Install the NeoPixel Library, available here : https://github.com/adafruit/Adafruit_NeoPixel After download it, rename the directory to 'Adafruit_NeoPixel' and place it into the directory 'librairie' into the directory of your IDE installation. The Arduino program of the clock is available on Github : https://github.com/pierreboutet/fibonacciClock Download it, and open it with the Arduino IDE Plug the arduino board with the usb wire, et upload the program from the IDE. wire, et upload the program from the IDE. +
- Follow the given scheme to weld wires. I tape wires in order that they stay in place. Only wire on the Arduino board aren't weld. +
- Glue the 4 sides with the double-bottom, positioning it at 5cm from the front. Wait until the glue dries. (20 min minimum) +
- Once dry, glue the separations. +
- Prepare now the other side of the double-bottom : To fix the electronic board, and avoid screw exceed from the wood board, we add wood thickness where we want to place the electronic board. +

- To get good opacity, i place a tracing-paper between two transparent plexi. Thus, it is enough opaque to transmit light homogeneously. And LEDs aren't directly visibles. Idealy one unique white plexy board non opaque would fit, but I didn't have any. +
- You can plug your clock, and learn how to … You can plug your clock, and learn how to read time. :) How to read time ? Squares have values of the Fibonacci sequence : 1 1 2 3 5 Red squares count for hours, Green squares count for minutes, and blue squares count for both hours and minutes. We get hours and minute by addition of the matching squares values. For minutes the values must be multiplied by 5, because the clock count by 5 minutes steps. Exemple, on the below picture : We addition red and blue squares for hours, it gives : 1 + 3 + 5 = 9h and green and blue squares for minutes, multiplied by 5, it gives : (1 + 1 + 3 ) * 5 = 25min It is so 9:25 (1 + 1 + 3 ) * 5 = 25min It is so 9:25 +
