Week 1: Principles and practices, Project Management¶
The task assigned by FATLAB for this week is to plan and outline a possible final project and some characteristics and requirements to develop this idea.
Possible final project¶
The project consists of developing a portable house for guinea pigs with wheels where water and food will be installed and according to the animal it sees consuming, it will be registered with sensors so that it can be increased according to need. The data will be sent to a receiving device to keep track of everything in real time.
Sketch¶
The idea¶
Regarding the project, the proposed solution to solve the problem is a mechanism that facilitates the process of feeding smaller animals such as guinea pigs automatically. It allows owners not to be physically present at their feeding but will inform them when the food and water run out. I will use this model as a reference of my project
The portable cage will also include a sensor so that as the food is running out, more food enters and the same of the water and that sends us that information in real time.
Components¶
Next I will proceed to detail the necessary components for the elaboration of the cart.
Hardware / Mechanical pieces: * Electronics housing made out of acrylic. (Computer-Controlled Cutting) * Custom actuators and sensors housings. (3D Scanning and Printing) * Cart made out of plywood. (Computer-Controlled Machining)
Sensors (Input Devices):
- Load cell: Integrated in the cart to register the weight of the collected products.
Actuators (Output Devices): * LCD screen: Necessary to show all the information collected * Buzzer: Alarm for maximum weight reached or waypoint completed
Control board (Electronics Production):
- Design of a board with all the inputs and outputs necessary to control the functions of the cart
Extras: * Comunicación inalámbrica. (Redes y Comunicaciones) * Visualización de datos. (Interfaz y Programación de Aplicaciones)
To send the information collected by the sensors to a receiving device and display a graph and maintain constant monitoring to avoid the end of your food.
Fab charter¶
What is a fab lab?
Fab labs are a global network of local labs, enabling invention by providing access to tools for digital fabrication
What’s in a fab lab?
Fab labs share an evolving inventory of core capabilities to make (almost) anything, allowing people and projects to be shared
What does the fab lab network provide?
Operational, educational, technical, financial, and logistical assistance beyond what’s available within one lab
Who can use a fab lab?
Fab labs are available as a community resource, offering open access for individuals as well as scheduled access for programs
What are your responsibilities?
safety: not hurting people or machines operations: assisting with cleaning, maintaining, and improving the lab knowledge: contributing to documentation and instruction Who owns fab lab inventions?
Designs and processes developed in fab labs can be protected and sold however an inventor chooses, but should remain available for individuals to use and learn from
How can businesses use a fab lab?
Commercial activities can be prototyped and incubated in a fab lab, but they must not conflict with other uses, they should grow beyond rather than within the lab, and they are expected to benefit the inventors, labs, and networks that contribute to their success
Task¶
- Build a personal site describing you and your final project.
- Upload it to the class archive.
- Work through a git tutorial.
Understanding GIT¶
GIT¶
Git’s distributed collaboration model is completely different, providing each developer with their own copy of the repository, with their own local history and branch structure. Users typically need to share a series of commits, rather than a single set of changes. Instead of pushing a set of changes from a working copy to the central repository, Git allows you to share entire branches between repositories and the project is shown
The git remote command is a part of a larger system that takes care of synchronizing changes. The records inscribed using the git remote command are used in conjunction with the git fetch, git push, and git pull commands. All of these commands have their own synchronization responsibilities, which can be found at the corresponding links.
GIT REMOTE¶
Remote repositories are versions of your project that are hosted on the Internet or any other network. You can have several of them, and in each one you will generally have read-only or read-write permissions
- git add . : The git add command adds a change to the working directory in the staging environment. This tells Git that you want to include updates to a particular file on the next commit.
- git status : The git status command displays the status of the working directory and staging area. It allows you to see which changes have been staged, which ones haven’t, and which files Git isn’t going to track. The status output does not show any information regarding the history of the project.
- git commit -m : Commit. It is the smallest unit of change and can be described as a point in history. It is important to note that a commit summarizes the changes as if they were patches to a file and does not contain the files themselves. This technique allows to reduce the size of the repos and optimize the synchronization.
- git push origin master : The git push command is used to push content from the local repository to a remote repository. This is the equivalent of git fetch, but while fetching commits are imported to local branches, committing commits are exported to remote branches. Remote branches are configured using the git remote command
Fab Academy Student Agreement¶
In order to upload content to my page, I downloaded ghostwriter where I can make the changes I need.
In order to update the content of my page and upload it to the web I have to open Gitlab
I have to go to my folder
Now we work with git add where it adds a change of the working directory in the staging environment and with git status it allows to see the changes that have been prepared.
git commit will open the locally configured text editor and prompt you to enter a commit message
Now we upload content from the local repository to a remote repository
When reviewing your page it must be updated
