Introduction: Eye of Sauron Inspired Tower

Hello and thank you for looking at my Instructable! In this instructable I will show you how I builded an Eye of Sauron inspired tower. Enjoy!

Step 1: Step 1: Needed Parts

To build the Arduino you'll need the following parts:

-Arduino Uno
-2 Servo's
-Wires
-Joystick
-Breadboard

Because I had two Arduino Uno's at home, I used one to add light to my tower. In case you want this, use the following:
-Arduino Uno
-Yellow Led
-9v Battery
-More wires
-Switch

To build the tower you'll need these parts:
-Polyurethane foam
-Foam Paper
-Paint
-Paper Mache
-Fimo Clay

Step 2: Step 2: Start Building the Arduino

The most important thing during this project is to make sure your Arduino works, before building the tower around it. Sadly, my Fritzing stopped working so I could'nt make a schematic. But the pictures above should work just fine!

I used the following code:

#include

const int servo1 = 4;

const int servo2 = 10;

const int joyH = 3;

const int joyV = 4;

int servoVal;

Servo myservo1; Servo myservo2;

void setup() {

myservo1.attach(servo1);

myservo2.attach(servo2);

Serial.begin(9600); }

void loop(){

outputJoystick();

servoVal = analogRead(joyH);
servoVal = map(servoVal, 0, 1023, 0, 180);

myservo2.write(servoVal);

servoVal = analogRead(joyV);
servoVal = map(servoVal, 0, 1023, 70, 180);
myservo1.write(servoVal); delay(15);

}

void outputJoystick(){

Serial.print(analogRead(joyH));
Serial.print ("---");
Serial.print(analogRead(joyV));
Serial.println ("----------------"); }

Step 3: Step 3: Build the Tower

Cut several circles from the foam paper and place your Arduino, breadboard and the servo's between the circles. Make sure your tower moves smoothly. When the arduino is placed within the circles, cut squares from foam paper and place them around the arduino and servo's. That way, your electronics stay protected when we use the polyurethane foam.
When the polyurethane foam is hardened, use a knife to cut out the shape of the tower.

Step 4: Step 4: Smooth Your Tower

After cutting and carving the tower, cover it with a layer of paper mache. This is important to be able to paint the tower and to get rid of the holes the foam left us. Keep checking if the Arduino still works!

Step 5: Step 5: Let There Be Light

While building the tower, I later realised adding a light would be a cool idea. I cutted open the top of the tower to use the hollow space. I powered my extra Arduino Uno with a 9v battery and attached a toggle switch to it. The led is placed in the GNB and 13 on the Arduino. I used the following code:

int led_pin=13;

void setup() {

pinMode(led_pin,OUTPUT);

}

void loop()

{

digitalWrite(led_pin,HIGH); delay(500);

digitalWrite(led_pin,LOW);

delay(500);

}

Don't forget to make the eye. I used transcluent fimo clay to glue arount the led light.

Step 6: Step 6: Finish Your Tower

Because the servo's can't carry too much weight, the materials for the tower must be light. It's hard to make a perfect tower with foam and paper mache, but don't be afraid to try. That's why I called mine an Eye of Sauron 'Inspired' tower. Feel free to paint the tower just as you like.

Do you have a video of the finished build in action?
