Concepts

Moire Kinetic Sculpture

In the Moire Kinetic Project we will be coding and laser cutting to create an RGB LED rotating moire sculpture.

Project Constraints

These are the constraints of our project. This tells us what we have to do in order to be successful while doing this project.

Project Benchmarks

These are benchmarks that we complete to stay on track during this difficult project.

Laser cut name

I used the laser cutter to cut my name out onto cardboard.

RGB

When doing the RGB LED we had t upload the codes to our arduino and correctly wire the wires in order to get the correct pattern of light colors, red, green, blue.

LED Pumpkin

I used inkscape to design my pumpkin, I next used the laser cutter to print my design, I then assembled my pumpkin.

IMG_1183.MOV

Servo moving left to right

I coded to make my servo motor move left to right and the servo motor will be used for my moire sculpture rotations.

Servo Mount

In this Benchmark I created a mount for my servo on inkscape and I then laser cut the design onto cardboard.

Gear Box Parent Gear 2x Child Gear Speed

In this benchmark I built a Gear box where the parent gear moves at twice the speed of the child gear.

IMG_1210.MOV

Gear Box Parent Gear Same Direction as Child Gear

In this benchmark I built a gear box designed for one of the child gears to move in the same direction

IMG_1598.MOV

2 servos 1 arduino

In this benchmark I had to make two servos function and one LED controlled by the same Arduino.

IMG_1567.MOV

Gear Box 2 Independently rotating disks on one shaft

In this benchmark I made a gear box that would be able to rotate 2 disks one shaft with one gear that controls each disk.

2 Moires on CAD

After sketching a moire I had to transfer and complete it on Inkscape and I will laser cut it and use it for my prototype and final moire.

Moire Sketch

These would be transferred into CAD and used for my final moire and prototype.

Cardboard Moires

In this benchmark, the moires we created in Inkscape are meant to be laser cut onto cardboard. The cardboard moires will be used for our prototypes. The laser cutter is under technical difficulty right now and Ms. White will trouble shoot the software later.

All Cardboard Pieces

In this benchmark I printed out my moires that I designed and Inkscape. I also printed out the rest of the pieces that are required to complete my prototype.

Solid Works File

I used this file in solidworks to help me assemble my moire prototype sculpture. I moved around the moire in solidworks to know where things belong in the sculpture.

Moire Code

With this code, I controlled two servos and one LED to create my moire sculpture. One servo was delayed while the other started a few seconds after. The servos are what made the gearbox functional.

#include <Servo.h>

Servo myservo1;

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()

{

myservo1.attach(8);

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

myservo2.attach(7);

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

pinMode(redPin, OUTPUT);

pinMode(greenPin, OUTPUT);

pinMode(bluePin, OUTPUT);

}

void loop() {

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

delay(1000);

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

delay(1000);

setColor(255, 0, 0); // red

delay(1000);

setColor(0, 255, 0); // green

delay(1000);

setColor(0, 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);

}

Cardboard Sculpture

The purpose of this functional prototype evaluates what needs to be improved and to test the codes we will use for the final product. The cardboard was easily broken and my moire began to crumble and fall apart. With the final materials, I believe that my sculpture will be way more stable. If I could remove pieces and get a closer look into the sculpture on solid works, it would have been easier to assemble and the sculpture may be better without the front acrylic like in the SolidWorks file. I believe that I should make the stars and lines in my moire thicker to make it more stable.

Install Servos

I installed my servos by screwing the ends into the acrylic. The servos will be used to help turn my gears and rotate my moire.

2 Final Moire Cutouts

These are my modified moire's for the final sculpture. In my prototype, my moires were too thin, so I modified my second moire's lines to be wider.

Install Arduino

I installed my arduino onto my middle acrylic to ensure that it would be stable and to make sure it'll be completely attached to my sculpture.

Assemble 3 layers of Acrylic

I assembled all three layers of my kinetic sculpture, which will help it function correctly.

Independent Servos

My two servos will cause the moires to spin. Each moire will spin independently due to the gears and how I code my moires to move.

IMG-4917.MOV

RGB LEDs

I coded my LEDs to go RGB. I made all of them function through a parallel circuit.

Final code

#include <Servo.h>

Servo myservo1;

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()

{

myservo1.attach(8);

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

myservo2.attach(7);

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

pinMode(redPin, OUTPUT);

pinMode(greenPin, OUTPUT);

pinMode(bluePin, OUTPUT);

}

void loop() {

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

delay(1000);

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

delay(1000);

setColor(255, 255, 255); // yellow

delay(200);

setColor(235, 235, 235); // yellow

delay(200);

setColor(215, 215, 215); // yellow

delay(200);

setColor(195, 195, 195); // yellow

delay(200);

setColor(175, 175, 175); // yellow

delay(200);

setColor(155, 155, 155); // yellow

delay(200);

setColor(135, 135, 135); // yellow

delay(200);

setColor(115, 115, 115); // yellow

delay(200);

setColor(95, 95, 95); // yellow

delay(200);

setColor(75, 75, 75); // yellow

delay(200);

setColor(255, 255, 255); // yellow

delay(200);

setColor(35, 35, 35); // yellow

delay(200);

setColor(15, 15, 15); // yellow

delay(200);

setColor(0, 0, 0); // yellow

delay(1000);

myservo1.write(180); // set servo to mid-point

delay(1000);

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

delay(1000);

setColor(255, 0, 255); // red

delay(1000);

setColor(0, 0, 255); // green

delay(1000);

setColor(0, 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);

}

This is the final code for my kinetic sculpture and it's what will cause it to function.

3 servo and LED patterns

I coded my moire kinetic sculpture to have three distinct light patterns and three distinct servo motions.
