17. Applications and implications¶
This week I worked on propose a final project masterpiece that integrates the range of units covered. [Reference]
Why I am doing it?¶
When I was the age about 8, my family could not afford a smartphone for entertainment. However, kids need to play, so I always go to the arcade game center and play physical game machines there, and I love that. Then how about make my own one.
Also, many children around the world can’t afford a smartphone, console, or such games, so it will be great to have an inexpensive plan to entertain.
What will it do?¶
A small catching ball game machine that can be created with digital fabrication tools. Players can get points by catching balls. It is small enough to be carried by one person, and can be powered by a mobile battery instead of a household power source.
Who has done what beforehand?¶
In the first week, I did an initial research for the project. I’ve found video that match with “Catch Ball Game Machine” but isn’t portable, and it’s definitely for commercial.
I’ve also looked up the FAB Academy site to see is there any similar topic that I can reference. And I’ve found this from Yoshihiro Asano, Fab 2021:

Although it’s not exactly what I want to do, it’s worth to be referencing.
What will you design?¶
-
The Project logo (Adobe Illustrator)
-
The Game Machine Enclosure (Fusion 360)
-
The 3D Printed PingPong (Fusion 360)
-
The PCB Board (Fusion 360)
-
The Game Program (Arduino IDE)
What materials and components will be used?
Where will they come from?

Total costs of my project is around 42 USD
What processes will be used?¶
Additive:
- 3D print using RAISE3D N2 Plus
Subtractive:
-
Milling PCB board by Roland Modela Pro MDX-500
-
Cutting the logo sticker for sticking on my game machine using Brother ScanNCut CM900
-
Laser cut for some small parts using GCC LaserPro Spirit
Programe:
-
Interface programming using Processing
-
Embedded programming using Arduino IDE
Other:
- Electronics soldering
What questions need to be answered?¶
How to detect the ball through the ring/hole?Is the lever stable and safe enough?Who can play? Playable for children?
How will it be evaluated?¶
- Functional success? like can it count the score by detecting the balls through the IR sensor…
- Could the balls fly?
- Is it safe enough?
