The Original™ Fibonacci Spiral Clock
About this deal
This clock comes with a ten year guarantee and a leaflet with some mathematical ideas to explore - in a classroom or at home. The send one was an answer to a popular number riddle: If a pair of rabbits, male and female, can mate and every month their offspring produce a pair of male and female rabbits.
Mark this point by tracing the inner as well as the outer curve of the Fibonacci spiral on the metal sheet using a pencil/marker.To keep time while unplugged the DS1307 chip needs a 3V battery connected to pint 3 and 4 of the chip. The Fibonacci clock lets you know the time more subtly, by changing colours and requiring you do some adding up. We take intellectual property concerns very seriously, but many of these problems can be resolved directly by the parties involved. We are part of an even older company - Richard Griffin 1820 Ltd - which has over 200 years of publishing history. It is possible to arrange squares whose side lengths are the numbers in the Fibonacci sequence into a rectangle.
I am using a standard 400ml spraying can and there is plenty of free space after wrapping the paper on the can. The idea is to create 5 square compartments in the clock, two inches deep, matching the size of the five first terms of the Fibonacci sequence, 1, 1, 2, 3 and 5.The Fibonacci sequence is a sequence of numbers created by the Italian mathematician Fibonacci in the 13th century. The clock pin 5 (SDA) is connected to the Atmega328P pin 27 (Arduino A4) and the clock pin 6 (SCL) is connected to the Atmega329P pin 29 (Arduino A5).

The screen of the clock is made up of five squares whose side lengths match the first five Fibonacci numbers: 1, 1, 2, 3 and 5. You will find all the details on how to connect the Atmega328P to make an Arduino clone on my post “ Build an Arduino Clone“. If you have followed this instructables properly and made everything properly the paper sheet should snugly fit on the sheet. Print the file in A4 and cut the center hole as well as the curved markings and wrap the paper onto the metal sheet.Once the spiral is cut it might have deformed depending on the skill to cut the sheet metal, don't worry flatten the spiral using a mallet. I had to squint my eyes to measure the time since the color of Fibonacci spiral and minute hand were same. Now rotate the knob on the backside of the clock machine such that the minute hand completes 1 full rotation.
Cut 4 plywood board for outside walls, 2 others for bottom and double-bottom, and 4 littles more for inside walls to split squares. Made from specially chosen scratch resistant polymer, light enough to manage the extraordinary movement yet resilient enough to last.Beautiful and fun at the same time, the clock uses the famous Fibonacci sequence to display time in a brand new way.
