Week 16: Applications and implications¶
Assignments:¶
- 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, 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.

-
Define the scope of a project
-
Develop a project plan

DOUBT: What does it mean by “what questions need to be answered?” Answer: It means the things you need to figure out or learn to be able to make your final project
DOUBT: How do I know I have completed this module? Answer: You have answered all the questions on “have you”-section and documented your plan for the implementation of the final project
DOUBT: Why do I have to answer these questions? Answer: These are questions to help you plan your final project. Answer these and any other questions you think will help you do this
Project development¶
Neil said something on the recitation which I really liked which was: “Propose a final project masterpiece that integrates the range of units covered” referring to masterpiece as showing mastery. I understand my path in the Fab Academy as a time to learn different skills, resources, techniques and machines which I will later apply in different future projects, giving the real importance to how good we have learned those skills and not the project itself. Regardless of this for my first spiral I will be designing part of the future kitchen of my van so I better master it!!!
For this week’s assignment I had to answer the following questions:
What will it do?
I will be designing a kitchen module that incorporates:
-
a sink with the water jerrycans, water pump and faucet where water runs.
-
storage for tableware, pots and pans. I want them to be as fixed as possible to avoid movement when on the road.
-
propane canister storage and gas stove to cook food
-
structure of the module and countertop
-
drawers and sliding doors
I will also design some waterproof and lightweight tiles to avoid wood walls to get wet from cooking and washing.
I will also design a gas sensor that measures the gas in the van and alerts if it gets too high by turning on a red light and a buzzer.
I will also connect the gas sensor to an interface on my phone to regulate all this from an app.
Who’s done what beforehand?
- I know Andrew after Fab Academy he also made his van and in this link he explains how he did the gas installation, etc. So I will look at this for reference. There are also a lot of references online which I am already looking into.
What will you design?
-
Kitchen module as seen in the sketch above taking into account lightweight materials, the total weight, openings, doors, secure closing, secure storage, measurements regarding the rest of the van, etc.
-
Wall hexagon tiles by creating moulds which I have some tests done from wildcard week.
-
Gas sensor with corresponding security box, I have been working in this in my input device and interface programming week already.
-
Interface which connects to gas sensor.

I added their origin in the project development page.
What parts and systems will be made?
-
From the kitchen module I will design and create the structure of the 3 cabinets taking into account the incorporation of the different components after: water pump, sink, jerrycans, water system, gas stove, openings, gas canister. I have read the gas installation has to be done by a professional.
-
I will also make the tiles myself with moulds and different materials. Still not sure if I would use epoxy or if I would make tiles from just plastic using the different machines from the precious plastic org at one of their stations.
-
I will do the gas sensor myself and also connecting it to the interface using App Inventor probably.
What processes will be used?
-
For the kitchen modules I will first design them parametric using Fusion 360. I will do some tests with the laser cutter specially to test the openings. I will then cut the final pieces with the CNC and sand it manually (this will take a long time :) )
-
For the tiles I will use moulding and casting techniques.
-
For the gas sensor I will use electronics design, production and interface programming.
What questions need to be answered?
-
Is the design parametric?
-
Do the kitchen modules work with the rest of the components which I will not make?
-
Are the materials used lightweight, waterproof, and suitable to use on a moving space?
-
Is everything I have done suitable to run a legal check?
How will it be evaluated? how do you tell if you succeeded or failed? VERY important!!!!
-
If it works: drawers and cabinets open correctly
-
If it fits in the space I have it planned within the van.
-
If when connected to power source everything works fine: water pump, water running, nothing filters out, all the components fit in perfectly.
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 It does!
Where possible, you should make rather than buy the parts of your project It does, I will try to also buy as much second hand as possible too.
I have also worked out how the rest of the modules will work to see how they would fit with the kitchen module of spiral 1:
