Final Assignment

Introduction to Fabrication

12 Dec 2018

This weeks assignment was to fabricate something that incorporated a motor mount. I was pretty slammed the past couple of weeks between finals, projects, and life so I wanted make something that could be done quickly and I could get some much needed sleep. I’ve been having a tough time decidng what to fabricate for these assignments and I always want to make something that combines a variety of skills instead of just making something.

My original idea was to make a motor controlled webcam that would track your face. Having experience with both servos and face detection I figured I could use the motor to keep the webcam centered on the face. However throughout the semester I have been having trouble talking to software without serial connection. ( Side note: As I am typing this I realized I could have used something other than p5, Processing would have been ideal in this scenario ) Anyways after tinkering a ilttle bit on my raspi I decided that this was not the path I wanted to go on and wanted to simplify further.

After going shopping on the Junk Shelf, I found a cork eyeball that could be fun to use. I wanted to incorporate the mechanism I had in mind and the eyeball would serve the same feeling as a moving webcam…surveillance. ‘




I first traced on a piece of pinewood the size of the servo motor.

Next I drilled holes into the pine wood so that I could go to the scroll saw and thread the blade in to cut out an interior hole in the pine. The hole was a little small to squeeze the servo in so I filed away a bit to squeeze in the motor.

The next step I did was take a long piece of wire and threaded it into the horn of the servo. I twisted the wire to give it more strength. I mounted the servo to the board using the supplied screws.

With the servo programmed and mounted to the board, the eyeball had a nice sweep effect. With the board I figured it would be easy to mount anywhere, but for purposes of class presentation I wanted to enclose the object to hide the micro-controller and the battery pack. I used a cardboard box that I found on the shelf and a hole in the bottom for the servo and mounted the plate to the box with screws. I found a cool little hook screw that worked perfectly for hanging.

The end result was a pretty crude eyeball that looks back and forth. In the future I want to go back and finish working on the the servo and webcam device.
