1. Propose a final project masterpiece that integrates the range of units covered. Your project should incorporate:

My final project incorporates:

• 2D and 3D design.

Since its inception, all the elements have been designed in 2D (AutoCAD) and later taken to one or several 3D parametric modeling programs. In fact my basis for all design is in principle to start in manual sketches / 2D CAD/ 3D CAM.

• Additive and subtractive fabrication processes.

In this project both additive and subtractive manufacturing are mixed in different sections, using different techniques and equipment. For example, the skin or casing of the base will be made in 3D printing (PLA) and the skin or casing that will cover 75% of the project will be made with vertical silicon in molds or containers made of wood or plastic.

• Electronics design and production.

The electronic design and production cannot be missed because without this there would be no project. It is one of the lessons that it has taken me more time to visualize and understand, but I am enjoying every step towards achieving each assignment.

• Microcontroller interfacing and programming.

This section, as well as the previous one, is essential to continue with the project and to understand what things can or cannot do each piece placed as components of our model to manufacture, from before and not waiting for the end and that the result is not what was expected.

• System integration and packaging.

I believe that integrating all the systems will be the part that will consume the most time, due to the delays due to the quarantine decreed in the country, but we hope to advance as much as possible in other activities. The packaging is considered as an essential part of the final product.

1. Assignments (2) Answered these questions?

• What will it do?.

The final project consists of an interactive LED lamp that uses, in addition to LEDs, 4 ultrasonic sensors and 4 servo motors to interact with people or, better said, run away from touch.

The interaction with people will be to relax especially the architecture students when they spend many hours doing assignments and to avoid stress and fatigue they can entertain themselves in something different, in addition to helping them illuminate the work environment.

• Who has done what beforehand?.

As far as I have been able to investigate, I have not found anything similar, however I have found several examples of projects dedicated to LEDs, servo motors and ultrasonic sensors that are mixed with 2 of these characteristics; but not with the 3 that I am describing.

• What will you design?.

It is the design of a lamp that, in addition to generating lighting, can interact with people in a way that makes us think and feel sensations that are not very common to human being.

• What materials and components will be used?.

• Where will they come from?.

Most of the components and materials are found within the FabLab. However, the most specialized components will be purchased outside the country.

See the table above

• How much will they cost?.

See the table above

• What parts and systems will be made?.
• What processes will be used?.

See the table above

• What questions need to be answered?.

My main concern is not being able to generate the physical products on time and programming them individually to generate an integration between all the components and materials before the end of the training date.

• I do not know what other components I require for the proper functioning of the project.
• How the use or disuse of certain components will affect the final project.
• How to code the program so that the results are as expected, without neglecting the simulations.
• How will it be evaluated?.

The project will be evaluated by how it works individually and when it is assembled in such a way that it can do the tasks for which it was created.

• Design and manufacture with the corresponding parameters.
• The boards with their circuits must work, in addition to turning on and off.
• The LEDs should light.
• Servo motors must start and turn.
• The assembly must be able to tilt when it detects the proximity of a person or thing.
