What is the Fibonacci sequence on a clock?
The Fibonacci clock lets you know the time more subtly, by changing colours and requiring you do some adding up. The Fibonacci sequence is the sequence beginning 1, 1 and where each number is the sum of the previous two. Its first five digits are: 1, 1, 2, 3, 5
What is a Fibonacci spiral?
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. A Fibonacci spiral gets wider or gets further away from the center for every quarter turn it makes.
What do the squares in his clock have side length?
The squares in his clock have side length 1, 1, 2, 3, and 5. The squares lit up in red tell you the hour, and the squares lit up in green give you the minutes (in multiples of five).

How do Fibonacci clocks work?
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. The hours are displayed using red and the minutes using green. When a square is used to display both the hours and minutes it turns blue.
Why is clock a Fibonacci sequence?
The clock works by combining a spiral arm, designed using a Golden Ratio rectangle or a rectangle comprising contiguous squares whose sides are Fibonacci numbers (i.e. the same thing).
What is a Fibonacci spiral clock?
This unusual clock tells the time with a spiral arm. To add a little mathematical beauty, the arm is a Fibonacci spiral meaning the line moves further from the centre by a factor of 1.618... (the Golden Ratio) for every quarter turn.
What is the Fibonacci golden rule?
The essential part is that as the numbers get larger, the quotient between each successive pair of Fibonacci numbers approximates 1.618, or its inverse 0.618. This proportion is known by many names: the golden ratio, the golden mean, ϕ, and the divine proportion, among others.

How do you find the golden ratio of your face?
First, Dr. Schmid measures the length and width of the face. Then, she divides the length by the width. The ideal result—as defined by the golden ratio—is roughly 1.6, which means a beautiful person's face is about 1 1/2 times longer than it is wide.
What is the golden point of Earth?
As noted above, the exact golden ratio point is 111.246…, or 21.246… degrees from the equator. The latitude of Mecca's northern most border is 21.592 degrees, and the latitude of Mecca's southern-most border is 21.278 degrees.
Where is the Fibonacci sequence found in nature?
On many plants, the number of petals is a Fibonacci number: buttercups have 5 petals; lilies and iris have 3 petals; some delphiniums have 8; corn marigolds have 13 petals; some asters have 21 whereas daisies can be found with 34, 55 or even 89 petals.
What is the golden ratio in simple terms?
The golden ratio or golden mean, represented by the Greek letter phi (ϕ), is an irrational number that approximately equals 1.618. The golden ratio results when the ratio of two numbers is the same as the ratio of their sum to the larger of the two numbers.
What is the difference between Fibonacci and golden ratio?
The relationship between the Fibonacci Sequence and the Golden Ratio is a surprising one. We have two seemingly unrelated topics producing the same exact number....The Golden Ratio = (sqrt(5) + 1)/2 or about 1.618.11322431.5551.66666666666667681.645 more rows
Why is 1.618 so important?
The golden ratio of 1.618, important to mathematicians, scientists, and naturalists for centuries is derived from the Fibonacci sequence. The quotient between each successive pair of Fibonacci numbers in the sequence approximates 1.618, or its inverse 0.618.
Why is it called the golden ratio?
Throughout history, the ratio for length to width of rectangles of 1.61803 39887 49894 84820 has been considered the most pleasing to the eye. This ratio was named the golden ratio by the Greeks. In the world of mathematics, the numeric value is called "phi", named for the Greek sculptor Phidias.

Who said the clock is for curious people?
Philippe Chrétien says the clock is for “curious and inventive people who like a time piece that keeps them on their toes.”
Is the clock lovely?
I think the clock is rather lovely. Although you would stare at it adoringly for a while before realising you were late.
Who noticed that numbers are all you need to express all the numbers from 1 to 12?
Philippe Chrétien from Montreal, Canada, noticed that these numbers are all you need to express all the numbers from 1 to 12.
Can you arrange squares whose side lengths are the numbers in the Fibonacci sequence into a rectangle?
Here’s what he did. It is possible to arrange squares whose side lengths are the numbers in the Fibonacci sequence into a rectangle. (This is the famous golden rectangle - here’s a previous post about that ).
Making a custom enclosure
I wanted to use up some curly redwood I’ve had in the shop for a long time. To make the four sides of the enclosure, I cut the pieces with 45° bevels on their ends so I could build the box using miter joints.
But how do you tell time with the Fibonacci Clock?
No worries, Philippe included a handy card in the kit. It’s not difficult, and it actually kind of fun! As a former homeschooling dad, this would make a great learning tool for kids.
Plans
Note: my plans are based on Philippe’s original Sketchup drawing and modified to fit my situation. They are not perfect. I suggest you review his plans if you want to make your own enclosure. All of Philippe’s materials are open source and can be downloaded here.

Step 1: What Is a Fibonacci Spiral?
Before understanding the Fibonacci spiral we need to understand the Fibonacci number and Fibonacci sequence. Fibonacci numbers form a sequence such that each number is the sum of the two preceding ones, starting from 0 and 1. So, 0+1=1, 1+1=2, 2+1=3, 3+2=5, 5+3=8, 8+5=13... We get this sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55... 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. A Fibonacci spiral gets wider or gets further away from the center for every quarter turn it makes..
Step 2: Preparing the Clock Machine
For this step you need an analog clock quartz machine, I have repurposed it from an old broken clock.
Step 4: Modification to the Fibonacci Spiral
The Fibonacci spiral we have drawn is in one dimension but to make a needle we need to have a surface area hence we will offset the curve inwards by 3mm.
Step 5: The Spiral Clock Needle (1)
The spiral needle needs to be lightweight as well as stiff. This is the step that took a lot of time since I had to search for different materials. The solution that came to be was to use a 1mm plexiglass sheet but cutting the sheet into a spiral was a big hurdle.
Step 6: The Spiral Clock Needle (2)
Once the can sheet is flattened stick the Fibonacci spiral paper on the metal can sheet using paper glue. Let the glue dry. Once the glue is dry drill a hole on the center of the spiral of 5 mm ( this corresponds to the hour shaft diameter as measured in the earlier step). Now start cutting the outer curve of the spiral using a tin cutter.
Step 7: Clock Base
For the base, I am going to use a 1 mm thick GI metal sheet. Stainless steel is preferable. The sheet needs to be stiff. Draw a center line dividing the shortest length of the sheet.
How many numbers are in a Fibonnaci clock?
Originally artmaker43 developed Fibonnaci Clock.exe and Fibonnaci Clock Screensaver.exe, Windows executables that use the first five numbers of the Fibonnaci sequence (1, 1, 2, 3, 5) using squares with those values along each side. This simulates counting all the way to 12. Then by keeping track of the number of 12s (plus the values less than 12) with painted squares, one can construct a 24-hour clock.
What is the green button on a clock?
The green button to switch between to set the hour or to set the minute
How many zones are there in the clock?
The clock is divided into three independents zones: hours, minutes and seconds that use the Fibonacci sequence (1,2,3,5) to simulate counting all the way to 12.
What does a circle in the hour zone mean?
In the hour zone we can find one labeled circle (PM) to indicate when the current hour is on the second 12-hour period (from noon to midnight).
What clock does the DS3231 use?
It uses a DS3231 I2C real-time clock with battery input to set and maintain the time.
How to read time on a Fibonacci clock?
To tell time on the Fibonacci clock you need to do some math. To read the hour, simply add up the corresponding values of the red and blue squares. To read the minutes, do the same with the green and blue squares.
What is the Fibonacci sequence?
The Fibonacci sequence is a sequence of numbers created by the Italian mathematician Fibonacci in the 13th century. This is a sequence starting with 1 and 1, where each subsequent number is the sum of the previous two. For the clock I used the first 5 terms: 1, 1, 2, 3 and 5. The screen of the clock is made up of five squares whose side lengths ...
What is the pin number for the FTDI port on an Arduino?
Pin 2 (RX) of the FTDI port connects to pin 3 of the Atmega328P (Arduino 1-TX) and pin 3 (TX) of the FTDI connector connects to pin 2 of the Atmega328P (Arduino 0 – RX). Finally FTDI pin 4 goes to 5V and 5 and 6 to ground.
What are the buttons on Arduino?
The three buttons attached to Arduino pins #3,#4 and #6 are used together to change time. Button on pin #3 can be used alone to change the color palette of the LEDs. An extra button is attached to pin #5 to change between different modes of the clock. Two modes are lamp modes and the default mode is the clock. All buttons are connected to the Arduino pins with a 10K pull-down resistor in parallel.
What color are the hours on a clock?
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. The hours are displayed using red and the minutes using green. When a square is used to display both the hours and minutes it turns blue. White squares are ignored.
How thick is a clock separator?
The separators are 1/16″ thick and can be made of any opaque material. The dimensions of the clock are 8″x5″x4″. The front of the clock is a piece of 1/8″ thick semi-transparent plexiglass. The separators are marked using a Sharpie pen.
