Our project is to create an eco responsible food app in order to prevent about consumption and pollution.


Through these steps, you will be able to follow our approach and our progress !

  • Environnement & Comsuption

We wanted to make a project related to this theme which is important to us.

1. First of all, we looked for what could be the most polluting products, in order to find out which products we should target. Here are some examples:

-Plastic (cups, bottle, bags, straws, cutlery, ...)

-Tea bags



-Paper (bags, tissues, ...)


2. And after, we search for already existing solutions :

-Edible straws


3. Afterwards, here are the ideas we reached :

-a system to clean the streets of big cities from cigarette butts by swapping the amount of cigarette ends picked up for a reward (money, discount coupons, etc)

-an eco-responsible delivery service (app), using bikes but edible or degradable cutlery as well. Besides, a service that would recover the dishes once finished (reusable ceramic plates by the company: inspired from the Korean delivery system).

/!\ Remark: need to broaden our vision, larger scale. For this --> mind map

1. During the first session our main project idea was the eco responsible food app. However an app does not require to build something with the available tools (3D printer…)

We gave up on this project and started to find other ideas.

2. Here are the main ideas we came up with during this session :

- Improve the public toilets sanitary

Smell, paper on the ground

Maybe by using some colorful lights

Is it possible to change people's behavior ?

- Luminotherapy in the transports as a substitute of the solar light

Is it really effective ?

- The RER Kit

How to improve the well being of people in the underground system/ RER ? (SDG : health)

The kit could be composed by :

* Something to choose your station and if you fall asleep it rings (each seat or each row)

** An alarm for women (if they are attacked, annoyed, harassed) : it will look like an emergency button (like a buzzer). It needs to be accessible but how if it is accidentally pressed ?

*** Sensors (like in parking) to say how many seats are left : green = the seat is available, red = it's not


3. Then we started to design a paper version of our respective ideas.


/!\ : Although these ideas need more electronics than the first one, they encounter another problem : are they really related to one of the 3 SDGs ?

Focus bubble

Working in a common space can sometimes be complicated, especially because of the surrounding noises. For some people, it is really difficult to concentrate if there is not total silence around them. Besides, in some school like ours, there is only one small common space for everyone so it is hard to focus on what you are doing.

Our idea is to create an individual workspace particularly for students, with all the equipment they might need. The goal is also to make it as small as possible so that many can be placed in a limited space.

References :

After we searched and compared the different materials and solutions that we could use for the development of the structure (walls). The challenge is to find the most soundproofing and cheapest material as possible. Here are few leads we found to inspire us :

--> inspiration from the professional equipments in the musical field (studios)

--> hardware store

--> DIY

Other track : shape of the structure

During this session, we continued to think about the materials and shape that our project requires.

More precisely, we calculated what were the most suitable measurements for the structure and for its interior layout. So it's to realize the actual size that we imitated the measurements of the base with tape on the ground (photos). Then, we asked for a tall man to stand in it to see how much space he was taking. Furthermore, we looked for "human measurements" used by architect (image).

Size : 1m-1m-2m15 (see the drawing)

Additional idea:

An interface (box) with: a button for the light, a timer, an usb port, an electrical outlet.


N.B : Pictures : A big thanks to the model Jules Canou who agreed to pose for us.

Time to actually build something !

We started to make a mini interactive version of our project.

One team was on the construction of the structure while the other was doing tests to find out which material was the best for soundproofing.

Building team:

They've done it via Illustrator to cut thin wood planks thanks to a laser cutter.

Testing team:

We used a speaker and a mic with in between various materials as cardbord, bubble paper, polystyrene and foam. We subjected them to different type of sounds : high frequency (3000Hz), low frequency (300Hz) and the sound of a crowd because the voice frequency ranges from approximately 300Hz to 30Hz (look at the pictures for details on the experiment)

*cannot update pictures*

We split in three teams to be more efficient :

1) Making of the structure:

  • The box is made out of wooden planks cut thanks to the laser cutting machine for a clean result. The different faces are assembled with screws.
  • The inside furnitures were designed and made with the 3D printer. We made a desk, a bench and a footrest

2) Making of the lighting:

Already programmed LED with a remote control are available on the internet but we preferred to do it ourselves. We wanted to use LED stripes but we finally used [ ]. 

3) Making of the timer:

Here a the link used:

  • First inspiration (circuit/code)

--> https://skyduino.wordpress.com/2012/08/28/arduino-minuteur-minutes-secondes-avec-buzzer/

  • How works an "afficheur 7 segments"

--> https://zestedesavoir.com/tutoriels/686/arduino-premiers-pas-en-informatique-embarquee/743_gestion-des-entrees-sorties/3424_afficheurs-7-segments/

However, instead of using an "afficheur 7 segments" we choosed to use an LCD 16x2 to have the benefit of having a screen so we can display messages. It means that both the electronic circuit and programmation part have to be adapted. Moreover, we combined it with an I2C to simplify connections (only for wires needed). For that we just had to weld the two components together.

--> https://ouiaremakers.com/posts/tutoriel-diy-connecter-un-ecran-lcd-en-i2c (steps)

  • Downloaded Arduino library

--> https://drive.google.com/file/d/0BxFOZP_yVG0lVzNLSkMzdEYtQU0/view

  • Code just to write something on the LCD display

#include  <Wire.h>

#include  <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x3F,20,4);  // set the LCD address to 0x27 for a 16 chars and 2 line display

void setup()


  lcd.init();                      // initialize the lcd





void loop()


  // when characters arrive over the serial port...

  if (Serial.available()) {

    // wait a bit for the entire message to arrive


    // clear the screen


    // read all the available characters

    while (Serial.available() > 0) {

      // display each character to the LCD

Final touches

After assembling the walls of the box we put an adhesive soudproofing material on every side on the outside (to not lose space on the inside). The interior walls were paint with a white bomb and the floor is left bare.

A  cardboard box was made to put the timer and all its components. For this we had to create buttons as well.They were made with a spring system.

Holes for the ventilation were made in the ceiling with a drill. Besides, hinges were fabricatedd for the door using cans.

Finally, all the furnitures, decoration and accessories were add in the box and fixed: the light has been installed, the 3D printed objects glued, the boards attached, etc
