  Lie Detector 

  Lie Detector v 1.0

  For our pulse sensor assignment, I wanted to do something with the data that revealed something a bit more personal about the person. For the Lie Detector, I went for an old carnival type of look. If the user’s pulse jumps above 75 BPM, the LOL shield displays the word “lie.” If the BPM stays normal, then a happy face is displayed.

  Lie Detector v 2.0

  I definitely wasn’t happy with the construction of the original prototype, so I attempted to make a more finished enclosure for this version. I decided to make a retro look and feel for the device. The actual enclosure is a wooden box. I decided to lose the LOL shield and use simpler, more universal feedback to let the user know whether or not a lie was being told. I drilled holes through the front for LEDs and capped it with red and green plastic tops. I also added a velcro strap to the actual pulse sensor, which dramatically increased the reliability of getting accurate pulse readings.

  Lie Detector Final

  

  What was lacking from the second prototype was there was no indication that the lie detector was working. I added in some LEDs on top to convey that part of the experience. To finish the look, I laser cut the words “lie detector” and hot glued them to the front. The user first straps themselves into the device by velcro-ing the pulse sensor to their index finger. They are asked a question, and after answering, the black button is pushed to begin BPM analysis. The LEDs on top blink to show that it is calculating, and then the result is displayed by either lighting up the red or green light.

  While initially made for fun with friends, it could also be used in other practical situations as seen below.

  Harry Potter “Pumpkin” v 2.0 

  For one of my final projects in this class, I decided to improve upon my Harry Potter pumpkin enclosure made for Halloween.

  To recap, the Harry Potter pumpkin interacts with you based on proximity. From far away, he is sad and sits quietly with red eyes. As you move closer, he becomes curious– his eyes change to green and the tip of his wand lights up. If you are really close to him, his eyes change to blue and he hums the Harry Potter theme song.

  In order to make this more of a finished piece, I obtained a new enclosure. The head is a plastic container. I drilled holes in the sides to accomodate for the mini speaker wiring, and to expose the photocell at the top. I used  chopstick for the wand and covered it with black felt. Hook up wire runs from the inside of the head to power the light.

  Parts Used

  RGB LEDs
  White LED
  Mini photocell
  Arduino
  Mini speakers

  Digital Aquarium 

  For this project, I used an arduino, tilt sensor, photocell, and LOLshield to create a digital aquarium. At rest, the fish sits peacefully in its tank. If the tank is disturbed, the water flows and the fish swims around. The fish can also be fed food by placing your hand at the opening of the tank.

  
  Fish at rest

  
  Food dropping in

  The animation was created using the LOLshield theater. A photo cell was used to control the food animation, and the tilt sensor for the fish swimming.

  The video in this post is a slight upgrade to what I showed in class. The animation was originally kind of confusing, because the water flow didn’t include the fish and wasn’t at the same height as the “fish at rest” position. I tweaked it so that the fish swam around when the tank was disturbed, which usually is what happens when you shake/tap a fish tank.

  To make this project a bit better, I need to fix a couple of the dead LEDs that are on the board. I’d also like to change the interior of the tank; maybe framing the LOL shield in a castle, and placing the castle on gravel/marbles and using blue tissue paper. The vase does look better than my first enclosure though. It was a plastic cube, see below.

  char buffer[10];

  int val = 0; // value of photocell input
  int buttonState = 0; // variable for reading the pushbutton status
  
  void setup()
  {
   Serial.begin(9600);

   // initialize the LED pin as an output:
  
  // initialize the pushbutton pin as an input:
   pinMode(buttonPin, INPUT);
   pinMode(photoPin, INPUT);
  }
  
  void loop(){
   // read the state of the pushbutton value:
   buttonState = digitalRead(buttonPin);
   val = analogRead(photoPin);
   Serial.println(val);
  
  // check if the pushbutton is pressed.
   // if it is, the buttonState is HIGH:
   if (val <=600){
   eat();
   }

  The Harry Potter Pumpkin 

  The Harry Potter Pumpkin is a social pumpkin that interacts with you based on proximity. From far away, he is sad and sits quietly with red eyes. If you move a little closer, his eyes change to green and he turns on the light from his magic wand. When you are REALLY close, his eyes change to blue, his wand lights up completely, and he hums the Harry Potter theme.

  
  Final Video

  
  Final Pumpkin

  Parts used:
  LEDs
  RGB LEDs
  8 Ohm mini speaker
  mini photocell

  

  Whats happening:
  The photocell values dictate what the other components do. The largest value keeps the RGB LEDs (the eyes) red. The medium range changes the RGBs to green and lights the tip of the wand. The lowest range changes the RGBs to blue, lights up the entire wand, and plays the Harry Potter theme from the speaker. I looked up the sheet music for HP  to compose the tune.
  
  Testing out the circuit

  I had to tweak my original concept, which was having the pumpkin shoot different spells the closer you approached it. The Twig sound recorder was so difficult to work with. I was able to record spells, but controlling it through the arduino was tough. The sounds kept looping instead of playing one at a time, so I decided to change my concept a bit.

  If I could redo this project, I would use the sound shield, which seems to be easier to control with the arduino, so that the pumpkin will actually shoot spells.

  CODE:

  #include “pitches.h”

  int analogPin = 4;   //Set value for analog pin input from photocell into arduino

  int red = 3;        // If serial reads val <= 700, red will go HIGH

  int green = 4;      // If serial reads val >= 701 or val <= 825, green will go HIGH

  int blue = 5;       // If serial reads val >= 826, blue will go HIGH

  int wand1 = 9;

  int wand2 = 10;

  int wand3 = 11;

  int wand4 = 12;

  int wand5 = 13;

  int val = 0;         // Store value of pin input (i.e. photocell) for serial to read

  int melody[] = {

    NOTE_B3, NOTE_E4, NOTE_G4, NOTE_FS4, NOTE_E4, NOTE_B4, NOTE_A4, NOTE_FS4};

  // note durations: 4 = quarter note, 8 = eighth note, etc.:

  int noteDurations[] = {

    4, 3, 8, 4, 2, 4, 1.5, 1.5 };

  void setup(){

   Serial.begin(9600);

   pinMode(red, OUTPUT);

   pinMode(green, OUTPUT);

   pinMode(blue, OUTPUT);

    pinMode(wand1, OUTPUT);

   pinMode(wand2, OUTPUT);

   pinMode(wand3, OUTPUT);

   pinMode(wand4, OUTPUT);

   pinMode(wand5, OUTPUT);

  }

  void loop(){

   val = analogRead(analogPin);  // Read the value (amount of light) from photocell

   Serial.println(val);           // Print out the value to the serial port

   if(val <= 749){

    digitalWrite(blue, HIGH);

    digitalWrite(wand1, LOW);

  Harry Potter Pumpkin 

  1. Ze Harry Potter Pumpkin

  2. This magical pumpkin lights up and shoots spells based on how close a person is to the pumpkin. The eyes and wand of the pumpkin are LEDs and a sound recorder plays back 3 different spells.

  3. I was having a lot of issues with the PIR sensor, so I switched to the miniphoto cell. This actually ended up being a good thing, because I can assign different values based on distance instead of just one with the PIR. The RGB LEDs make it more playful and integrates emotionality to the pumpkin; the closer you get to it, the more aggressive the spells get.

  I haven’t had success with the sound recorder just yet. I’m missing the JST female connector, but with the new soddering skills we’re picking up today, I should be able to work around it. There’s also something funky going on with the wand part. It lights up, but its super dim.

  maker faire-ish 

  I was out of town the week of maker faire, but the festival I was working at had some cool stuff.

  This is chroma. It’s an “interactive ecosystem” that responds to human disturbance.
  

  The team used arduinos to control phillips bulbs. They were realllly pretty and responded to touch. It felt like being in a room with a bunch of floating jellyfish.

  This isn’t very pcompy, but I thought was interesting. I heard the mind behind Bjork’s Biophilia music app album speak. They released a series of apps for each song on the album. Each app is a different way to experience the song. My favorite was virus–in order to hear the song in its entirety, you have to let the cell die.

  hello! 

  Sorry for the delay, just got my WP set up…

  Hi! I’m Hirumi. I studied Biology/Neurobiology as an undergrad and worked for a few years in Student Affairs in Higher Ed before pursing an MFA in DT.

  I’m exploring plant geekery for my thesis. Must learn pcomp so I can use those righteous sensors.

  My fave: The Toy Cash Register.

  

  I’m pretty sure I played with this bad boy right up until teen-hood. Clicky buttons. Magic numbers. Ringy sounds. What’s not to love? Oh haiii pcomp. Lets do this.
