The FabChapter

I met the Fab Lab network in Peru in mid-2017 and had the opportunity to attend the Fab13 world event, in Santiago de Chile. In this event, all the laboratories meet to share the knowledge acquired each year and where the new students of the Fab Academy will graduate. This year 2021, I became a Fab Academy student and I am excited to explore further. Whenever I talk with friends, the question arises about what a fab lab is and what they do. Here you can read a little what it implies.

The Fab Lab network operates globally and is a network of laboratories equipped for the invention. Here you will find a community that will support you to develop any original idea, thanks to the inventory, prototyping machines that they have and accumulated knowledge of different areas.

CASE BOSSThe chosen idea

Wandering in "the parallel of ideas"; I was encouraged to develop a complement, a case, for 3d printers that come without a frame. This is due to the fact that in my atelier, in general in my city, there is always too much dust and humidity is always higher than 80 percent. I watch with concern as the small metal parts of the 3d printer begin to have a corrosion orange color.😱

The idea is that the case protects the 3d printer from dirt and allows visibility, it could be transparent or translucent. It will have a humidity sensor to monitor it and calculate the state of the material. It will also have a temperature sensor to have the values ​​of the ambient temperature within the same case. These two values ​​would help us to control and correctly set the parameters that we upload to the software when we pass our designs into code. Every time I use the printer in the future I will be able to see how the environmental indicators are and I will be able to take them into account to set my parameters. I thought of adding assisted ventilation for materials that need it or for when the temperature is concentrated. I recently used my 3d printer, I am not an expert at all, and sometimes the printer takes many hours to bring out a model, so sometimes I fall asleep while it is printing. I think I could add a shutdown system to the case or warn me in some way that the printing is over.

Considerations & Materials

Considerations to take:

• Design a case with universal measurements, which comes in a kit.
• Moisture monitoring should help us keep track of the state of our material and structure.
• The case must be designed to work in different climates.
• Assisted ventilation.
• The case must rock!

Materials "Beta Version"
The materials that my project needs are perhaps many more than those I have put here, I consider this list as a starting point:

• For the structure I want to use 4mm or 5mm transparent polystyrene
• Humidity sensor
• Temperature sensor
• SD storage
• Complement: Dashboard (to view the data)
• WiFi connection
• LED lighting

I think this design can contribute to many designers who are just entering the world of digital fabrication and who have good 3d printers, but with bare structures. I hope that the case helps to optimize the quality of the prints and protect the device.

RoundTwo 🥊

This first week of Fab Academy 2022, is a new encouragement to finish this adventure full of knowledge. As part of the Fab Lab Esan node students, we have had an interesting week of bootcamp, where we have been able to review and learn basic concepts of electronics and programming. One of the final assignments.

After analyzing a bit the project I proposed in the 2021 cycle "CaseBoss", the smart case for my 3D printer, I decided that it is a project that I need and that I will develop anyway, but this cycle I want to propose a project with greater impact on the daily lives of more people. So, applying the spiral learning system, I will go back to the beginning, reset my ideas and here we go with the new project.

OHMMIEThe new idea

"Oxygen in a human body varies directly proportional to the power of the breath applied, and inversely proportional to the flow rate of inhalation and the speed of exhalation." -Stef, 2022-

Ohmmie, (it's called Ohm, but you can call it Ohmmie 🧡) is an interactive assistant trainer that teaches people to breathe in different ways, with controlled rhythms that promote greater oxygenation and consequently help to relax. This device has various breathing rhythms set to be chosen and imitated by the user, is friendly, luminous, and connects the user with his own breathing through his senses. This visual biofeedback tool, for all ages, gives us the opportunity to improve our ability to concentrate, to breathe better and relax, and to stay in good emotional shape. It is a beautiful device that will also decorate any of our everyday environments.

Throughout this season, I have seen people close to me suffer from high levels of stress, including myself, and the consequences of having these levels on a recurring basis is that it affects physical and mental health. Needless to say that measures such as lackdown, caused by the Covid-19 crisis, aggravated people's emotional states with negative effects. Anxiety or diseases such as fibromyalgia can be aggravated or caused by stress. Fortunately, breathing and exercises are accessible measures that help us to counteract the symptoms and progressively improve.

Considerations & Materials

Who does it help?
It supports patients, athletes or various people with anxiety problems who need to do relaxation breathing (like yoga) and oxygenate their body in a more efficient way and thus reduce anxiety and stress levels. When people are stressed they do not breathe correctly.

Considerations to take:

• The design shall be user friendly, perhaps of some soft material or with organic shapes.
• The device will be as compact and portable as possible.
• The lighting and how I will control it is very important. I will play with the intensities.
• It should be able to stand on its own to be used as decorative furniture, as long as it is not used as a trainer.
• If possible, it will have the option of being an aromatic oil diffuser to activate the sense of smell as well. This device should of course rock! 🤘

Materials
These are some of the materials I will probably use:

• For the structure I want to use maybe TPU, PLA or TPE.
• IMU sensor, it is a mix of sensors, accelerometer, magnetometer and gyroscope.
• Wind sensor ( Anemometer)
• LED illumination
• 9 volt power supply.
• Buttons.
• Wires.

Why is it useful?
I believe that this project will allow me to develop an interactive device that will be very helpful for all the people who suffer from stress and I would like to continue researching this topic since I have been affected by the overloaded life of tasks that causes stress.

I found out this example are built and work.

OtherIdeas

I thought of other projects, like:
A device that helps keep the machines in a laboratory, in the workshop, in our homes, turned off, when we go to sleep and forget to turn them off. It would be an energy saver.
A low cost pedestal that serves to see the routes of buses and bicycle lanes in my city, connected to the internet, for a constant update and live analysis, so that later one can be implemented in each stop, I know that there is an app to cell phone that does something similar, but not everyone has enough megabytes to use it daily, in addition to how unsafe it is to take a cell phone out on the street.

Lately, the amount of MEGAS that one has in their mobile phone plan to navigate on their cell phone has become a very important asset, without megabytes you cannot mobilize in the new internet normality.
I also thought of developing parametric zomes with rhinoceros and grasshopper, or perhaps parametric lonaria to grant low cost modules, generating shady spaces to my city, eternally white and radiant to the max. Anyway, I had many ideas, and if you are interested in any of them, you are welcome to talk about them.

AboutLearning

-Thinking on a final project idea from the beginning of the course is an important issue. But I recommend that you let your creativity fly, because the project is flexible and may evolve over time.

-In the repository of the Fab Lab network, there is too much information and many inspiring projects. Taking the time to review it is ideal.

My Verdictfrom what I learned

-This week, it's very creative. Although you feel a bit of pressure to quickly decide the final project.
