For this class assignment I exercised the mounting of a DC motor from Adafruit's experiment kit using a custom mount created from the accessories that accompany blinders set for mounting on window's houses.
The plastic enclosures that are mounted on windows wooden frames provided me with the right size of mount, containing plenty of wholes in which to place fasteners to fix the mount onto any piece of wood.

This approach provided me with a convenient way to re-use the accessories from old blinders instead of discarding them.

I proceeded then to test the motor in action by connecting it into an Arduino circuit board and see how it worked within the mount.

The next step was to mount a small structure on the motor's shaft, I decided to cut out a circle from a vinyl sheet and place it right on the gear.

I tested the mounting by turning on the motor and observing the vinyl circle spinning stably
