The Original™ Fibonacci Spiral Clock

Product Information

The Fibonacci sequence is a sequence of numbers created by the Italian mathematician Fibonacci in the 13th century. Philippe Chrétien says the clock is for “curious and inventive people who like a time piece that keeps them on their toes.

Draw a line perpendicular to the centerline on this point using a compass draw a circle of 70mm diameter on this point and divide the circle into 12 equal parts resembling a clock numbering base.To enable personalised advertising (like interest-based ads), we may share your data with our marketing and advertising partners using cookies and other technologies. Use power tool if it eases your job, here I have used basic tools so that it will be easier for any one to replicate this instructables. Fibonacci popularized the Hindu–Arabic numeral system in the Western world primarily through his book Liber Abaci (Book of Calculation). Fibonacci numbers form a sequence such that each number is the sum of the two preceding ones, starting from 0 and 1. Philippe Chrétien from Montreal, Canada, noticed that these numbers are all you need to express all the numbers from 1 to 12.

The top pin is attached to the second needle/ make sure you do not damage the needle although we are going to use only 1 needle in this Instructables the rest could be useful for other Instructables. The solution that came to be was to use a 1mm plexiglass sheet but cutting the sheet into a spiral was a big hurdle. Before understanding the Fibonacci spiral we need to understand the Fibonacci number and Fibonacci sequence. Without these technologies, things like personalised recommendations, your account preferences, or localisation may not work correctly. Because if you have to multiply the minute by 5 you can never get a number that is not a multiple of 5.The Fibonacci spiral is a spiral that is built by constructing arcs that connect the points of these squares based on the Fibonacci sequence that is assembled in a spiral pattern. Mark this point by tracing the inner as well as the outer curve of the Fibonacci spiral on the metal sheet using pencil/marker. Now rotate the knob on the backside of the clock machine such that the minute hand completes 1 full rotation. Print the file in A4 and cut the center hole as well as the curved markings and wrap the paper onto the metal sheet.
