Final Project Journey

Step 1: Concept Stage

The concept for the project is to create a simple yet entertaining device that would incorporate all the elements of DFAB such as 3D printing and Laser Cutting yet was simple enough to recreate.
My idea for the final project is a useless machine, a device that has no actual purpose other than entertainment of a user from observing how it turns itself off if the switch it has is switched on. Many different concepts were drafted, but due to time and material constraints a more traditional design was selected for my project.

Concept 1:

This was deemed to be too complicated and time-consuming.

Concept 2 (Chosen):

Thus this design was chosen with options to increase the fun value
of the project such as adding LEDs and Sound makers.

Step 2 : Construction and CAD

The main body of the useless machine was developed from my parametric modular ‘perfect fit’ box with details such as dimensions altered to fit my project. The body would be created using Laser Printing to form the shapes that made up the cuboid body.

The 3D printed arm and hinges are altered designs from thingiverse changed to fit into the dimensions of the body, with 3D printing allowing the exact dimensions I require for my design to be produced.

This is the arm of the Useless machine, changed so that it can touch the switch from it’s position just below the top casing.

Step 3: Construction and Coding

The Construction Process made use of all the skills i’ve learnt in DFAB, and had me operating a wide range of machinery, and as for the coding process, the code used was modified from a existing template, with me adding more variation into the speed of the arm, to be more entertaining to users as they repeatedly flick the on/off switch of the machine.
