Concepts of Engineering

Our first project in engineering we made wooden boxes, and we also made wooden hinges. It took a long time because we had to make notes on how to use tools, even though we already know how to use these simple tools.

We had to stain, cut, biscuit, plane, and sand our boxes and hinges to make the final product. The final product took about 2 months to make. The project was easy but very much over-complicated by the teacher.

Moire Kinetic Sculpture Brief

The Constraints

The Benchmark

Moire Design 1 Completed on CAD

This benchmark tested both our design skills and out knowledge of Inkscape. This took some trial and error but I was able to do it.

Moire Design 2 Completed on CAD

This is the second moire that we designed, but instead of paper we used Inkscape

Moire design 1 created on Cardboard

This was the result of creating the first CAD model of our moire sketch but we used the laser cutter to print it out.

Moire design 2 created on Cardboard

After we created the Inkscape file we were able to print the second design out on cardboard.

Two Servos and One LED controlled by an Arduino

We had to get one LED working with the two servos at once. The way I wired it was I had to connect both the servo wires to the five volt pin in the breadboard. I also had to connect the LEDs to the breadboard.

Perpendicular servo mount

We used the laser cutter to print a servo mount using the correct dimensions of the servo.

Functional Prototype from cardboard.

We made a functional prototype of our end project. We did this to make sure we knew how to make the end goal.

Gear Box With two Independently Rotating Disks

We made a functional Gear box using Laser cut pieces and different sized gears.

All pieces printed out

We had to make sure that all of our cardboard pieces were printed out.

3D solid Works File

This is a Final CAD model of the project and serves as the model to help guide the process of making our final project. There were some problems however... the bearing hole was too small and the holes for the LED's were too small. The holes for the dowels were also too big. I need to fix those before the final design.

Working Moire Prototype

The functional prototype serves as a model and a way to understand how your final product will come together. This also finalizes the code, so you know what code you are going to use for the final product. You will also be able to know what changes you will have to make. Although there are many parts of the prototype that weren't functional due to the materials used. One of the changes we knew we had to make was the fact that many of the holes where not the right size.

Code for Moire Sculpture

This was the final code that will be used in the final product. We had to make the arduino's spin in different directions so they spin the moire. We also had to make the LED light up in different colors.

Code For Moire Sculpture

#include <Servo.h>

Servo myservo1;

Servo myservo2;

int red_light_pin= 11;

int green_light_pin = 10;

int blue_light_pin = 9;

{

myservo1.attach(8);

myservo1.write(90); // set servo to mid-point

myservo2.attach(7);

myservo2.write(90); // set servo to mid-point

pinMode(red_light_pin, OUTPUT);

pinMode(green_light_pin, OUTPUT);

pinMode(blue_light_pin, OUTPUT);

}

void loop() {

myservo1.write(0); // set servo to mid-point

delay(1000);

myservo2.write(0); // set servo to mid-point

delay(1000);

}

void RGB_color(int red_light_value, int green_light_value, int blue_light_value)

{

analogWrite(red_light_pin, red_light_value);

analogWrite(green_light_pin, green_light_value);

analogWrite(blue_light_pin, blue_light_value);

}

Install Servos in middle acrylic

Using the screws that we where given in class we were able to attach our servos to the middle acrylic.

Cut out moire 1 in Glowforge

Using the Glowforge laser cutter we were tasked to cut out the first moire out of wood. This was also the last moire we had to cut out.

Cut out moire 2 in Glowforge

Using the Glowforge laser cutter we were tasked to cut out the second moire out of wood. This was also the final moire to cut out

IMG_2515.MOV

Moires are independently controlled by the servos

This objective was achieved by inputting the code from the cardboard model into the new wood model.

IMG_2396.MOV

LED go RGB

We were only able to get the led's to go blue and green, but we are in the process of getting them to go red.

Install Arduino

In this task we had to screw our Arduino into our middle acrylic.

Assemble your three acrylic layers perfectly

The three layers that we were given in class should be assembled and put together.

IMG_2515.MOV

KS does three repeated light patterns

The LEDs that we assembled earlier need to have three light patterns.

IMG_2515.MOV

Servos do three distinct motion patterns

The servos that we have in our sculptures need to have three different patterns when rotating.

Final Kinetic Sculpture meets constraints

All the constraints that we were given need to be complete and finished.

Final Presentations

This is the final presentation that we did in class. I also had to make the video shorter in order to fit into the website.
