Project Management
This semester, I keep throwing cool project ideas into the shredder : ))
(Pinball machine is the final-final project, the rest are for reference.)
This semester, I keep throwing cool project ideas into the shredder : ))
(Pinball machine is the final-final project, the rest are for reference.)
Here are some highlights of the machine's system design:
(A) Surface / Pinball system:
1. 3D-Printed material
2. Movable gears and (Rotates or Bumps)
3. Customizable flexibility
4. Nice and smooth hitting experience
5. Other fun finishes
(B) Scoring System:
1. Scoring sensor > attach to end of body (step)
2. Scoring board > self-standing part (LED)
(C) Main Body :
1. Large format CNC cutting (OCB)
2. Assembly without glue
3. Modular design (for future carry)
4. Other cool features
Here are some highlights of the electronic design:
(A) Input:
1. Step response module
2. Detect number
3. Send to board
(B) Network System:
1. Receive data
2. Receive Codes (Creative visual coding)
3. Talk to LED
(C) LED Board :
1. Receive "touch" data: (number>xx)
2. Play a victory animation (random generates 3~5 animations)
3. Wait for 3~5 sec > prevent from multi-touching
4. Reveal score: plus one > reveal number
5. Receive "touch" data......
W1-W6: Nothing relates to final : )

W12: networking & communications >> control & interaction
W13: interface & application >> user interface
W14: wildcard week >> iron plate water jet
In 3D printing, it's common for prints to fail, leading to a significant amount of waste. The main challenge lies in finding efficient ways to reuse this material rather than discarding it.
I started collecting waste PLA prints by placing recycle bins next to the arch shop's 3D printers. (This is the most productive place for waste materials!)
The experiment involves using a heat press machine to heat the metal plates to around 240°C, melting PLA to reshape it into sheets that can be repurposed for other products. This method focuses on reducing waste by reusing failed prints.
I used a paper espresso cup to contain some PLA materials. To observe the blending of geometries, I found this fantastic black-and-white waste initially from another print of Neil's high-res portrait. In the end, the experiment successfully melted all the waste materials into a condensed espresso!
Using an iPhone silicone mold with higher temperature resistance, I was trying to use the same method from test 2 to bake the materials in the oven. However, the experiment was failed due to lacking controls of the shape of the ingredients, and a higher mold to contain materials.
