Pergola for pets is a retractable shelter system digital fabrication made which provides protection from the sun and it's assembled by plywood modules which design was made to allow increase or reduce it's size to adapt different kind of users like kids even adult people.

Plywood press fit kit structure.
Retractable system.
Input devices / Limit switch.
3d printed pipe holder / PVC pipe.

Alien face will attract attention to the button hole.
Along of the Fabacademy the parts were developed in relationship to each week assignments if you feel curious about that process please check the full documentation linked on my weekly evolution page. Pergola for pets is the integration of three different systems that complement to each other. You can download the files!

Wool shelter
The programs was made based on Neil c-codes examples and also developed by other fabacademy students.

What questions were answered?
The most fundamental parts of my final project are the main structure assembled, the retractable system, the system integration and packaging and the shelter.
To simplify the material for all the structure of the final project I choose plywood because work well to test the retractable system.
To simplify the shelter material I choose wool in relationship of the wild card week assignment.
How was it evaluated?
I think my final project has to be evaluated in relationship with the weekly evolution progress.
The main structure and the retractable system are the most important things.
The shelter system could work manually or automatically.
The design provide flexibility for the users since it could reduce or increase it's size.
Utility and according to the fulfillment of my objectives.
What are the implications?
Pergola for pets is the begging of a future development called pergola for humans that I want to make it real and it will be awesome and link it to the society between the architecture and the city.
Final project requirements:
Your goal is to keep it as affordable as possible
Design and fabricate your own parts instead of buying off-the-shelf components.
Prove mastery of the skills gained during the program.>
Learning outcomes: Create your own integrated design. Demonstrate 2D & 3D modelling capabilities applied to your own designs. Select and apply appropriate additive and subtractive techniques. Demonstrate competence in design, fabrication and programming of your own fabbed microcontroller PCB, including an input & output device.

PCB Debugging:
New board design:
Schematic: due to the problem I had with the drivers that they aren't enough powerful I decided to replace them and instead I embed the easy driver to my board and taking advantage of that I use the free pins to connect a sensor or maybe to connect the limit switch as a simple wired network and use the FTDI pins to connect a cellphone trough bluetooth.
Board: I had to download the easy driver library to install it in eagle and after that I place the component and make a mirror of it. You can download the library here. Also I add a DC power jack to make a better connection to the power source.

Traces: I like to give my boards something that identify me for that all of my boards had an alien face attached I like to call the boards I did the alien collection.

MILLING AND SOLDERING
DC power jack to makes easy the connection to a common power supply and are more free pins to connect a sensor or another device to the PCB.
Easy driver embedded in the board
PROGRAMMING
I did little changes in the code like the pins for DIR and STEP
And I have to enable this part of the code to make it work well.
