Alvin Aronson's original design (made with corian and wood):
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 papercrafting.
Step 1: Gather your materials
The Electronics Kit :
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
*Or use a pack of cheap lead pencils
Papercutter - Shiloutte Portrait (optional)
Dremel - to cut tubing (optional)
