Engineering Concepts

Moire Kinetic Structure

Moire Kinetic Sculpture Brief

It is a combination of software, industrial, electrical and mechanical engineering to build a nice home decoration.

Constraints

These are a list of requirements for the project.

Benchmarks

This is how we will get to the final product. Each benchmark requires a stamp that signifies where we are in terms of progress.

B1: Creating a Gear Box

I made two gearboxes. The benchmark stated that one must have a parent gear rotating twice as fast as the child gear, which you can see in the first video by watching the pencil marked notches.

The other one must have a child gear moving in the same direction as the parent gear, which can be seen in the second video.

B2: Laser Cutting my Name

I used the RetinaEngrave software to design and cut my name into a piece of cardboard as our second benchmark.

B3: LEDs go RGB

Our third benchmark required that we properly connect wires to a breadboard and arduino along with an RGB LED, and manipulate the code so that it shined red, green, and blue.

IMG_2925.MOV

B4: Get a servo to rotate left and right

For our fourth benchmark, we had to make a servo rotate to the left and the right.

IMG-0190.MOV

B5: LEDs go RGB

For our fifth benchmark, we had to write code which made our LEDs blink red, green, and blue.

B6: 2 Moire's that meet the requirements

For our sixth benchmark, we had to draw up two Moire's which represent what we want ours to look like, while also having functionality.

B7: Laser Cut Pumpkin with Yellow, Orange, Red LEDs

For this benchmark, we had to create a pumpkin in Incscape, and laser cut it. We then cut out connectors to connect the front and back pieces. After that, we used wiring and code to make the lights shine yellow, orange, and red.

B8: Perpendicular Servo Mount Created using Laser Cutter

For our eighth benchmark, we had to create a mount which could hold our servo upright.

Benchmark 9 and 10: Moire Designs Completed in CAD

For this benchmark, we had to create two moires in CAD software which were more advanced prototypes from our first rendition which we drew on paper.

Benchmark 11: Functional Prototype from Cardboard

For this benchmark, we had to laser cut cardboard to create the base model pieces for our first cardboard prototype.

IMG-0331.MOV

Benchmark 12: Two Servos and One LED all controlled by one Arduino at once

For this benchmark, we had to write code that would make two servos and one LED function at the same time, and then properly wire it with the help of a breadboard.

Benchmark 13: Solidworks

We used the Solidworks file to laser cut the pieces for out prototype and map out where our gears and servos would be placed.

Benchmark 14: Code

Below is the code we used to allow the servos to rotate independently and the lights to shine specific colors.

----------------------------------------------------------------------------------------

#include <Servo.h>

Servo myservo;

Servo myservo2;

int redPin = 11;

int greenPin = 10;

int bluePin = 9;

//uncomment this line if using a Common Anode LED

#define COMMON_ANODE

void setup()

{

pinMode(redPin, OUTPUT);

pinMode(greenPin, OUTPUT);

pinMode(bluePin, OUTPUT);

myservo.attach(3);

myservo2.attach(5);

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

}

void loop()

{

myservo.write(180);

myservo2.write(0);

setColor(255, 255, 255); // red

delay(1000);

setColor(0, 100, 100); // green

delay(1000);

setColor(100, 0, 255); // blue

delay(1000);

}

void setColor(int red, int green, int blue)

{

#ifdef COMMON_ANODE

red = 255 - red;

green = 255 - green;

blue = 255 - blue;

#endif

analogWrite(redPin, red);

analogWrite(greenPin, green);

analogWrite(bluePin, blue);

}

Benchmark 15: Presentation of Functional Prototype

The purpose of a functional prototype is to perfect a concept before finalizing the product. The biggest obstacle in terms of the material is the functionality of cardboard. Since the mechanisms are powered, and the cardboard is not strong, it tears and rips easily. The Solidworks file showed three servo mounts, however in our final prototype we used only two, which should be taken into account in the final product. Our original Moire file did not have the hole in the middle which would be used to rotate the discs, so we need to add that.

Benchmark: 16 Install Servos

For this benchmark, I had to install two servos in acrylic.

Benchmark 17 & 18: Cut out moire's using glowforge.

For this benchmark, we used the glowforge to cut out our moire designs to be used on our final product.

IMG-0713.MOV

Benchmark 19: Install and solder 8 LEDs so they go RGB.

For this benchmark, I glued 8 RGB LEDs into my acrylic. I then wired and coded them to go RGB.

Benchmark 20: Install Arduino into middle acrylic

For this benchmark, we had to screw our arduino into our middle acrylic to prevent wires and such from coming loose.

Benchmark 21: KS does three repeated light patterns

For this benchmark, we had to code our lights to repeat three independent patterns. My three patterns are separated by a ten second long violet light.

Benchmark 22: Servos have three distinct motion patterns

For this benchmark, we had to code our servos to move in three different ways and repeat.

Benchmark 24: Moires are independently controlled

For this benchmark, we had to glue one moire to the shaft so it could be controlled by our small gear, and we did not glue our second moire, which was controlled independently by a larger gear.

Benchmark 25: Assemble three acrylic layers perfectly

For this benchmark, we had to use our dowels to assemble the three layers of our project.
