☑ Where will they come from?
☑ How much will they cost?
☑ What parts and systems will be made?
☑ What processes will be used?

Task for this week

Propose a final project masterpiece that integrates the range of units covered.

Your project should incorporate:

2D and 3D design
Additive and subtractive fabrication processes
Electronics design and production
Embedded microcontroller interfacing and programming
System integration and packaging

Where possible, you should make rather than buy the parts of your project. Projects can be separate or joint, but need to show individual mastery of the skills, and be indepently operable.

See Final Project Requirements for a complete list of requirements you must fulfil.

The answers to the questions below will allow you to create your BOM (Bill of Materials).

Develop a project plan and what does it do?/what must i do?

Build a simple machine with three slopes to measure the time of descent. I have from 1 April to 7 June 2024.
Instructor suggest to add 3 LED strips that light up the slope according to which descent first and have a GUI to control it.
I will make sure that all parts are fully designed by me. except for the ESP32 Xiao C3 and input and output devices.
I will make sure that the curve is designed by me.
Identify the limits of my design and fabrication skills

1.1 What will it do?

I will have two random curve and one Brachistochrone curved path for ball. There will be a release mechanism that release the balls. It will be triggered by a start button. When balls strike the limit switch, it will record the time. The path that taken the shortest time will be gold, second be silver and third be gokd.

Due to my limited abilites, I have opted for a spiral development approach...

1.2 Who has done what beforehand?

Technovation had posted an article! in instructable. Honestly I like the work done as it is simple and neat and does the job.

NTP Physics and many science teachers have used the curve kit. But Seems like I cant buy any online directly.

1.3 What will you designed?

I will design
1. a foldable base made of cardboard, with mounting cavities for LCD, Buttons, Slope.
2. a arcylic slope for ball path.
3. a 3D print for mounting limit switches.
4. PCB (with ESP32 Xiao C3) to control the components required for experiment. 5. Arduino code for Process. 5. GUI to interact with PCB.

1.4 Materials and components

1.5 What parts and systems will be made?

I will made
1. a foldable base made of cardboard, with mounting cavities for LCD, Buttons, Slope with Laser Cutter.
2. a arcylic slope for ball path with Laser Cutter.
3. a 3D print for mounting limit switches with 3D printer.
4. PCB (with ESP32 Xiao C3) to control the components required for experiment with LPKF PCB Miller. 5. GUI to interact with PCB with Python.
