Digital:Analog Clock – Arduino + PaperCraft

In this instruct able we will be recreating a clock inspired by Alvin Aronson’s original design. When I first saw this clock I was very impressed by how clean an elegant the design was I immediately wanted to recreate this effect. I hope some of you feel the same and use this as a guide to be one-step closer to having one of your own
Essentially, we have a seven segment clock where instead of LED’s we have digits moving in and out of the pane, the shadow created by these digits will allow the user to read the time against the white on white digits. By using 28 servos, we can use a arduino to first process the current time and then push the digits out accordingly through the motor controller. more will be explained in the later pages.
I’ve tried to keep the parts as simple as possible, using readily available parts without a deep knowledge of electronics one can begin to explore creating their own clock. I do not have 3D printer so construction will be done by way of paper crafting.
Digital-Analog Clock – Arduino + PaperCraftHere are the things you’ll need. I intended to fit this in the “kit contest” category so I’ve limited the build to simple parts without need for soldering. Alternatively. Arduino Uno and motor-controller can be replaces with Arduino Mega which wall allow direct control of up to 64 servos. The build costs cost me around $130 in parts. Keep in mind you can reuses the parts to create other great projects like a Hexapod!
The Electronics Kit :
Arduino Uno
DS1307 or RTC clock breakout- keeps track of time
Servo motor controller – controls servo motors
28 Servos – they rotate 180 degrees
Hobby aluminum tubing* – To allow digits to slide smoothly ; need a inner and outer tube
Double sided tape
Sticky Pads
Paper Clip
