Overview

My project goal was to learn how to use my Raspberry Pi, as well as Fusion 360, to build something fun and functional.

At first I didn’t know what to make, hence I started experimenting with motor controllers and code, and eventually settled on making a clock.

Design + Prototyping

• CAD in Fusion 360
• 3D printed prototypes on my Bambu P1S
• After ~5 attempts, I found the right spacing for my stepper motor mount
• I made ~3 prototype “caps” that fit on the motor shaft and act as the clock hand

For simplicity, I chose to make a single-hand clock. I didn’t have two motors, and fitting two motors together would have been difficult.

Here’s the final design:

Electronics + Code

I researched how to program the stepper motor using the Raspberry Pi GPIO pins and wrote a simple program to rotate the motor at a user-set speed.

The video below is a sped-up demonstration (one full rotation per minute) to show the precision:
