Week 16 - Applications and implication¶
Assignments | Week 16 | Applications and Implications
Individual assignment
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 independently 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).
Learning outcomes
- Define the scope of a project
- Develop a project plan
My Final Project Masterpiece¶
I will design in 2D and 3D the packaging of the object, and also the electronic circuit.
I have to achieve 3 parts:
- Packaging
- PCB
- Interface
anecdote about my mind over complicating things
As I have take the thermometer outside, or stick it on the window to get the temperature, I imagined a waterproof and solid packaging for the embedded system that I’m going to create. I only know that PLA and ABS are 3D printing filament that we surely have because I have seen them. But I have no idea about their properties and what will happen if they are exposed to the sun and rain. Summer is coming and I know that I may do test under sunlight. So I would like to make sure the packaging will protect the PCB from hasards and don’t release toxic gaz while exposed to sunlight. This article on Google: https://tractus3d.com/knowledge/learn-3d-printing/filaments-for-outdoor-use/ compared the caracteristics of different type of filament. “PETG and ASA are 3D printing materials for outdoor use and durable (hold over time)”. So normaly PETG and ASA are great materials for my project. But I also have to check if they are in the inventory of our Fablab. Then, I asked my instructor, he said that ABS should be fine.
What will it do?
I decided to build a thermometer that could stick on the window and show the temperature outside.
Who has done what beforehand?
The electronic components
What will you design?
2D and 3D design
-
Sketch : System integration and packaging.
-
Fusion design
Additive and subtractive fabrication processes
- Packaging
Electronics design and production
- KICAD
Embedded microcontroller interfacing and programming
-
What materials and components will be used? Where will they come from? How much will they cost? What parts and systems will be made? What processes will be used?
What questions need to be answered?
- The purpose of the project and how does it work?
- Describe how the components of the PCB are going to work together
How will it be evaluated?
- The thermometer could be turn ON/OFF.
- The OLED display should print well the information.
