Fab Academy with a Newtonian Touch

Throughout the course I will be documenting my successes and failures on this space, making it my legacy and personal reminder of where I'm headed and how far I've gone.
Follow me on this journey towards a future where we can channel ideas into projects that will help people aquire a better quality of life.

About me

Growing up in Peru I encountered myself with a vast number of people that started life with several disadvantages.
As I rapidly recognized this I found myself daydreaming of a better world where we could get closer to giving fair
opportunities for everyone thus increasing the chances of new geniuses such as Newton and Tesla proliferating in their
environment instead of succumbing to harsh circunstances. I consider myself a multipotentialite (term I take from Emilie
Wapnick's TED Talk), I've tried dozens of sports, traveled over 9 countries and 6000 kilometers by bike living in my tent,
been to almost 30 countries (not sure if 26 or 27) and plan on traveling many more. True to all my passions and refusing
to decide for one I had a hard time finding a professional career that would let me explore the world, bring out my creative
side and generate knowledge while helping the world by shortening the inequality gap. I met Professor Fabricio Paredes during
an Automation course in the University of Lima and thanks to him I discovered the world of digital manufacture leading
towards the Fab Academy. Finally, I've become a student for this amazing course and I plan to dedicate myself fully to making
the most out of it hoping I can complete my dream of becoming a nomadic inventor.

Week 1: Principles and Practices

First Final Project Proposal: Turtle Startler

This design was done rapidly and while I plan on making it to help the WWF protect sea turtles at the moment its all I with and as my final project it most definitley will change as the course progresses. The idea is simple, using green LED's the Turtle Startler will scare away turtles from fishing nets while maintaining the average amount of fish caught. The device will generate its own energy by harvesting the kinetic energy generated by the tides and forward movement of the boat making it environmentaly sustainable and cheaper in the long term. It will have a metal clip for close to timeless attachment to the fishing net and a refracting pattern to increase the LEDs light emission.

Second Final Project Proposal: 3D Printing Filament Extrusor

My journey into digital manufacturing started through the world of 3D modeling and 3D printers.
Living in Peru I soon found out that the filament for 3D printing is very expensive (70$ for 1kg).
Given this circunstances I've decided to make an extrusor that compresses and heats crushed plastic into 3D printing filament.
It is intended to be easy to build so everyone that wants access to cheap filament can use it as an available option.
This will also help reduce the damage we do to the environment, the animals and ourselves.

Week 2: Project Management

Making my Website

I selected ECLIPSE from the plethora of free IDE's for web development out there to make my website after checking others such as BlueJ, JDeveloper, JEdit and many more.
As it was the first time I've actually coded in HTML5 (or any HTML versions for that matter) I turned to the many tutorials youtube has to offer to find out the basics.
Once I had a starting point my website code looked like this:


I quickly found out HTML5 is quite intuitive so I started trying simple things like adding images and different heading formats as shown in the screenshots below.


Having learned the basics I moved on towards finding a free template I could use. I checked several pages before finding a template I found apropriate:


After reading a bit about git I got the general idea. In order to push GIT repositories you have to follow several steps but once its done its quite simple.
As I wanted to use Windows knowing its limitations I downloaded GIT Bash for 64 pix Windows from https://git-scm.com/download/win.


Once downloaded the initial window looks like this.

For you to be able to push first you need an SSH Key.
I followed steps on "https://docs.gitlab.com/ce/gitlab-basics/start-using-git.html" to do so as shown in the screenshot below.
The next step was to configure my global username and email as shown in the next image.
Once these were set I cloned my git repository directly through Eclipse using the clone a git repository button and pasting my link from gitlab.

Week 4: Computer Controlled Cutting

Parametric Design: Laser Cutter

As a fan of platonic solids I decided to do a Dodecahedron for my press fit kit assignment. In order to do so I used the laser cutter shown on the picture below
Laser Cutter I tried to use Autodesk Inventor to design but I discovered the settings were off and it was stopping my progress so I changed to Fusion 360.
Since it was my first time trying Fusion it took a bit to get used to it but soon enough I was back on track.
Parametric01 My first attempt was a heptagon with 60 mm sides and 10mm squares to make it press fit with the other 12 heptagons.
Parametric02 Parametric03 Soon I found out there was a margin to consider due to the space the laser cutter takes when it cuts as the heptagons didnt generate enough friction to stay together.
FailedAttempt On the next attempt I designed a variable LENGTH = 40mm for the heptagon's sides.
Parametric04 Once this was done I segmented the side in 6 parts for the 3 rectangles and 3 absent rectangles (other pieces would fit there), now they were 4mm long and (LENGTH/6 + 0.35mm) wide for the rectangles and (LENGTH/6 - 0.7mm) for the spaces between them. I repeated this process 2 times after that until the formula was (LENGTH/6 + 0.1mm) for the rectangles and (LENGTH/6 - 0.2mm) for the spaces between.
Finally it fit and I had my dodecahedron as shown in the picture below (Next to the failed attempts).

Parametric Design: Vinyl Cutter

I decided to do a vectorized image of Zelda's Logo. I downloaded Corel X7 and once in I imported the picture of Zelda's Logo.

An assistant in the lab named Cesar told me there was an option to quickly vectorize any image on Corel so I checked the options in Bit Map to find it. VectorizedZelda
Following this I removed the color of the vectorized image.
After I sent it to the Vinyl Cutter.

This is how it came out: Vectorized Zelda
