Week 12 Mechanical & Machine Design

This weeks assignment

Here is a video of a hinge that I 3d printed for the doors
of projects that are being worked on.

3d printed hinge

A few 3d printed items that will be used

I ended up going in another direction from the original design.
Reason being, the first set of serrvo motors that I used were
not strong enough to raise the lid at a satisfactory level. I tried both 6g & 9g and was not satisfied with results.

Parts required for this project

- HC-SR04 Ultrasonic sensor (2)
- 25g Servo motor (1)
- Arduino unr R4 Wifi board
- Wires to connect devices
- Trashcan, small bedroom/kitchen size bin.
- 3d printed gears/ rack & pinion set
- chloroform board
- hot glue

I will update this list as the project persists.

This is a very rough draft of the final project. The updated version will have
a much cleaner look that will be easier on the eyes...lol. I just wanted to make
sure that the wiring and code worked. I will update pictures and videos as I
progress in this project. My goal is to fit 99% of the hardware/wiring in the lid.
This will make repairs & upgrades and future ideas alot easier to adapt to, in addition
to keeping this project simple and clean.
