# P1. Prototype!
:::info
The goal of this phase is to define & materialize 3 relevant product proposals according to the subject given.
:::

:::danger
Your prototype must be a physical object : diagrams, images, drawings and 3D files etc. will not be considered as prototypes.
:::
## Define & prototype 3 proposals
Our three proposals are combined into one model of a low-tech housing unit for homeless. When combined the three create a fully functional community. Ideally, a proper low-tech housing unit would incorporate all three of these inventions.  

### Proposal n°1 : Solar powered heating 

##### Actors
:::warning
- BY WHO? Low-tech engineers and social activists. Anyone wanting to improve sustainability as well as housing options for homeless. 
    - For solar energy - solar energy developers
- FOR WHOM? Homeless community in countries that can sustain these low-techs (countries with enough sunlight and rain)
- WITH WHOM? Sponsors and donors that will help financially support these low-techs (as they can often be costly).
:::

##### Context 
:::warning
- WHY? We want to provide a homeless housing option that is environmentally sustainable and allows those who use it to live comfortably and have all their basic needs fulfilled. 
- WHEN? Year round
    - The housing needs to be able to sustain the weather of the area and keep residents comfortable throughout the different seasons 
- WHERE? In a more rural area that can support the necessary infrastructure. 
:::


##### Features
:::warning
- WHAT? Heating for the housing compounds. 
- HOW? Solar powered technology would be installed by low-tech engineers with the help of volunteers. This would be financially sponsored by sponsors (such as organizations, government or individuals). The effects would directly benefit the homeless.

The eolienne is now fully functional and is capable of turning. Rather than using cardboard we switch to a thin wood we found in the Makerslab that allowed for the structure to be slightly more stable and supported its functionality. There is now two rotational parts that allow for the eolienne to rotate no matter what direction the wind is coming from.

### 4. Select the most promising proposal

Describe below the selection process of the most promising proposal :

:::warning
For our final prototype we chose to do the **solar powered heating.**
Our feedback on this proposal was relatively similar to the feedback we received on the other two proposals however what set this prototype apart from its counterparts was that it could incorporate much more easily the skills we learned in the course (laser cutting and programming an Arduino). The one disadvantage to this proposal (and all our proposals) is that it cannot easily be realized into the "real life" version. The prototypes would all have to be smaller versions and would need to be improved before they could actually be used in practice for a homeless housing unit. 
:::
:::warning
* This proposal will show a small version of the heaters our group would like to install in the low cost housing units presented in our issue. Its size allows it to be easily mobile, it uses a bare minimum of technology and it is very low cost to make, something we felt was crucial seeing as our project relates to the homeless.
* The first advantage is cost. The other protototypes would be much more expensive to realize. The low cost is a huge advantage relating to our topic as when it comes to building products relating to homeless housing, funding is not high. The second advantage is its ability to be made at home or "DIY". Something like a water collecter is massive and requires industrial equipment. Even for a large version of the heater, it is easy to make at home. 
:::

Describe below what are the features of your final project :
:::warning
1. Heating pane that absorbs solar heat (powered by panel)
2. Vents that circulate the air out
4. Arduino that signals to the vents at what temperature they need to start running 
:::

# P3. Design
## Make your final prototype
:::info
Now that you have defined what is your best proposal it's time to make a greater version of it. You will present it to the jury during the final evaluation alongside the early prototypes made in the previous phase.
:::
:::success
A good prototype is self-explainatory : the user must be able to understand how it works without instructions or user manual. It must be fully functional and sufficiently strong to withstand several demonstrations in real conditions of use.
:::
:::danger
For this phase it is **mandatory** to use at least :
- The **laser cutter** and/or the **3D printers** to build your physical “shell”
- **Arduino** electronics and/or **Adobe XD** to make your prototype interactive.
:::
:warning: <span style="color:red"> **Keep in mind that for the end evalutation the prototype will be the only way to communicate your project to the jury!**

Once you have decided what features to prototype and how, settle a meeting with the makers’ lab manager of your campus. He will give you some technical feedback and the material you need. Do not expect the makers’ lab managers to tell you what to build!

### Conception

- Use Adobe Illustrator or TinkerCAD to design your parts.
- Use Adobe XD and/or arduino to design interactions

This is the laser cutout of all the pieces required for the building of the shell. The first two skinnier pieces and the two smaller squares will be laser cut in wood while the other two larger pieces with holes must be laser cut plastic.

### Building process

Describe below the building steps of your demonstrator and insert a picture for each step :

:::warning
![](https://i.imgur.com/mFJqaga.jpg)

**step one** : Draw the parts that need to be laser cut on Adobe Illustrator. The size of these parts will depend on the overall size of the heating system. 
:::

:::warning

![](https://i.imgur.com/yu5RU0f.jpg)

**step two** : Laser cut the parts needed using the laser cutter. The two center parts should be cut in plastic and the others should be cut in wood. Gather all the necessary materials. 
:::

:::warning

![](https://i.imgur.com/GbOzZpl.jpg)

**step three** : Attach two of the 15 cm x 21 cm pieces of wood using 2 of the 21 cm x 6 cm of wood by attaching them into the holes like shelves. Put one of the 15 cm x 21 cm pieces on the top as a sort of lid. Use glue and tape to reinforce the structure if need be. 
:::

:::warning

![](https://i.imgur.com/MvkXvp0.jpg)

**step four** : Attach the plastic sheet (32cm x 20cm) to the bottom and top shelf making sure to tighten it as much as possible (so as to not let air in) and use tape to keep it positioned and reinforced. 
:::

:::warning
![](https://i.imgur.com/0lpwDPc.jpg)

**step five** : Using the plastic with the 4 circles cut out, create a template on the 11cm x 14cm piece of wood (as shown in the image). Attach the 1cmx2cm pieces of wood between each circle, as shown using glue. Wait for it dry. 
:::

:::warning

**step six** : Glue the wooden plaque onto the plastic plaque with the circular holes on it, so that the holes align. Make sure the legs are facing downwards so that the plaque is elevated.

**step seven**: Thread the connectors through the small holes in the wooden board so that the thicker part can be seen through the plastic board - this is where the fans will be attached

:::warning

**step eight**: Flip the plastic board to the side where the holes are, attach the fan to each connect so that it sticks out of the hole and so that it is capable of turning. 
:::

:::warning

**step nine**: Attach the plastic board with the vents on the side where the plastic sheet is tightened. Do not yet attach the back side of the structure.

**step ten**: Program the Arduino and the breadboard using Tinkercad and upload the code onto the Arduino by attaching it to your laptop using the blue cable. 
:::
