Welcome to Week 16
Applications and Implications
Hey! now we will learn about Application and Implications, for this week we have the following questions to resolve:
• What will it do?
• Who has done what beforehand?
• What will you design?
• 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?
• How will it be evaluated?
This is the first week in which we can fully focus on our final project, well now I will answer the necessary questions to better understand the scope of my project.
Let's start with the most important thing, let's see a summary of the final project idea:
The Idea for my final project
My project idea is based on the development of a tool generated with digital fabrication. This tool will allow us to enhance learning and provide support to children with attention deficit hyperactivity disorder (ADHD), creating a space for greater concentration through various musical and visual elements. It will take the friendly form of a cloud, which will possess a teaching system through educational apps, all aimed at improving the child's level of concentration.
NUBOX …….
Nubox has a quite friendly design, especially striking for children, this, accompanied by its shape, generates a feeling of tranquility. I made the following representation of my idea in the second week of Fab Academy. Many things have remained more or less the same in appearance, only some modifications in dimensions, in the central part it will have a 7-inch screen which will have an interface with games specifically designed to increase the child's concentration.
I looked for some background, which is reflected in my assignment 1, there I found that many developed apps or robots but not a portable version with a striking shape which will hook the child, the latter will help us generate greater impact
But how will I do it?
The central screen will have an interface which has games already designed to increase concentration and focus attention deficit, in addition to this it will be accompanied by white noise emitted by the two speakers placed on the back.
Who has done what beforehand?
For the final project, we worked previously, in different weeks to be able to integrate processes, in week 2 the structural design was carried out, in week 5 printing tests were carried out, within week 8 the electronic production was carried out to the light control system, in week 14 we learned about interface programming which will be used for the development of the final project.
What will you design?
This question led me to ask why I chose a cloud, now I will explain it to you...... among the many shapes that I could choose, a cloud was the best because it has a pompous shape and lends itself to adding accessories such as ears and horn which makes it more eye-catching, the 7-inch screen makes the interface very visible for the little one and they can use it like a tablet.
What materials and components will be used?, Where will they come from?, How much will they cost?
In terms of materials used, they were electronics found within the laboratory, such as a 7-inch Rapsberry screen, a module developed in the electronic production assignment, LEDs and speakers. In addition to this, use digital manufacturing such as 3D printing, laser cutting, vinyl cutting and electronic production.
| Materials and supplies | Product image | Function | Characteristics | Supplier and brand | Link | Quantity | Unit cost | Total cost |
|---|---|---|---|---|---|---|---|---|
| 1 | Raspberry Pi 3 B Plus whit accessories | Imagen | Controller | Low cost and compact size computer | Link | 1 | S/350.00 | S/350.00 |
| 2 | Touch screen 7'' | Imagen | Touch screen | Screen that by means of a direct touch on its surface allows the input of data and commands to the device. | Link | 1 | S/193.65 | S/193.65 |
| 3 | LED's RGB | Imagen | Lighting | Diode consisting of a semiconductor chip doped with impurities. | Link | 3 | S/0.70 | S/2.10 |
| 4 | 16Gb Memory | Imagen | warehousing | Removable flash memory card used for storage of information | Link | 1 | S/37.90 | S/37.90 |
| 5 | 4-ohm speaker | Imagen | Sound output | Robot audio output that allows you to listen to the sounds of the device's music. | Link | 2 | S/26.49 | S/52.98 |
What parts and systems will be made?,What processes will be used?
First, after having the 2D design, I started with the 3D printing of my pieces, taking into account what was seen in assignment 5, inclination and horizontal expansion tolerances.
Assembling all the pieces it would look like this:
Now a little test with the screen
For the electronic part I will work with a cpu in this case raspberry and in addition to that my development board worked on throughout the academy which will be a complement to the cpu
We will use the raspberry as a PC, to run the programs and games which will help the children increase their concentration.
In addition to this, I will use the board with Seeed Xiao RP2040 which I use throughout my assignments, this will have a function to control external lights, with a light sensor which when the light decreases will activate the lighting immediately through Cloud
So that it can be visualized, it is on a breadboard, however the LEDs will have a location in each piece of the nubox and the sensor also has its fitting.
Here is the list of materials.
- A LDR sensor.
- 3 RGB LEDs.
- 4 resistance of 1K.
How will it be evaluated?
Well, for the evaluation and validation of my project I will do tests on children between 6 and 8 years old, measuring the time and degree, visually of concentration in the nubox and the practicality of use.
Well, we will continue documenting this project, it will be something very interesting, see you next week
