About this deal

To keep time while unplugged the DS1307 chip needs a 3V battery connected to pint 3 and 4 of the chip. For this step you need an analog clock quartz machine, I have repurposed it from an old broken clock.

Philippe Chrétien says the clock is for “curious and inventive people who like a time piece that keeps them on their toes. The ratings/reviews displayed here may not be representative of every listing on this page, or of every review for these listings.You will find all the details on how to connect the Atmega328P to make an Arduino clone on my post “ Build an Arduino Clone“. You'll find real reviews of wall clock that will give you all the information you need to make a well-informed purchase decision. Cut 4 plywood board for outside walls, 2 others for bottom and double-bottom, and 4 littles more for inside walls to split squares. The LEDs are distributed in all squares and connected in the back of the clock to the circuit board. 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).

This clock comes with a 10 year guarantee and a leaflet with Fibonacci and the Golden Ratio explained in the leaflet. To add to the challenge, the combinations are picked randomly from all the different ways a number can be displayed. First, wrap the Fibonacci curve drawn on paper on the empty spraying can to check if it fits properly.Now rotate the knob on the backside of the clock machine such that the minute hand completes 1 full rotation.

The Fibonacci sequence is the sequence beginning 1, 1 and where each number is the sum of the previous two.

dxf files for fibonacci spiral and clock base, if you wish you can cut with a laser cutter and skip the hassle to build from scratch. After download it, rename the directory to 'Adafruit_NeoPixel' and place it into the directory 'librairie' into the directory of your IDE installation. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. Fibonacci numbers form a sequence such that each number is the sum of the two preceding ones, starting from 0 and 1. 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.And to work out the minutes just add up the green and blue squares and multiply by 5 (because the clock is accurate to 5 minutes). The Fibonacci clock lets you know the time more subtly, by changing colours and requiring you do some adding up. Made from specially chosen scratch resistant polymer, light enough to manage the extraordinary movement yet resilient enough to last.
