Smart thermometer (Stage 1):
Input: room temperature
Input: user preference
Arduino: compare room temperature and user preference
if user preference > room temperature
Output: turn on heater
if user preference < room temperature
Output: turn off heater

Arduino code:

int sensorPin = 0;  
int sensorValue = 0;

#include <Sensirion.h>
#define sensirionDataPin  2
#define sensirionClockPin 3
float temperature;
float humidity;
float dewpoint;
Sensirion tempSensor = Sensirion(sensirionDataPin, sensirionClockPin);

int pirPin = 13;
int slpPin = 12;
int ledPin = 9;
int rlyPin = 11;

void setup()

  pinMode(ledPin, OUTPUT);
  pinMode(rlyPin, OUTPUT);
  pinMode(slpPin, OUTPUT);
  pinMode(pirPin, INPUT);
  digitalWrite(slpPin, HIGH);

void loop()
  int pirVal = digitalRead(pirPin);
  if(pirVal == LOW){ //IF MOTION IS DETECTED
      digitalWrite(ledPin, HIGH);

      tempSensor.measure(&temperature, &humidity, &dewpoint);
      Serial.print("Temperature: ");
      Serial.print(" C, Humidity: ");
      Serial.print(" %, Dewpoint: ");
      Serial.println(" C");
      sensorValue = analogRead(sensorPin);  
      sensorValue = map(sensorValue, 0, 1024, 20, 40);
      sensorValue = constrain(sensorValue, 20, 40);
      if(sensorValue > temperature){
        digitalWrite(rlyPin, HIGH); //TURN ON RELAY
      else {
        digitalWrite(rlyPin, LOW); //TURN OFF RELAY
    digitalWrite(ledPin, LOW);
    digitalWrite(rlyPin, LOW);

void serialPrintFloat(float f){
    int decplace = (f - (int)f) * 100;

Team Otto - Week 1

Smart Roof

- Opportunity: holes on the roof
- Needs: light, insulation, water heating, solar energy generation, ventilation
- Design intent: intelligently negotiate between different needs
- Advantages: modular, basic infrastructure allows for expansion, integrated system

Some thoughts - trip to botanic garden

The inefficiency of tree's reproduction method:

Trees are hugely ineffective in self reproduction, however, the abundance of fruit produced are not wasted. Nature is a system and not singular organisms, so in this sense, one tree is providing means of surviving for a whole other chain of organisms.

Nature then, is perfectly balanced and completely efficient.

Team 4

Issue i thought that was apparent with the previous cylindrical reflective tube: 
- limited actual surface to capture heat, being only the circumference of the tube
- rely on the reflectiveness of the mirror material for efficiency
- solar panel not fully integrated into the solar capturing process, needs additional surface and installation

Solution i thought that was appropriate and effective to maximize solar energy capture for both water heating and electricity production:
- integrating solar panels with water heating
- rotating panels towards the sun
- maximizing surface absorption, rather than trying to concentrating solar power onto a limited surface (techinically complicated, and ineffective for the given situation. for one thing, the curvature of the glass is not a half cylinder, there is a specific curvature that we need to figure out)

Added value:
- let in diffuse light and block out direct light
- underside of the panels could be used for lighting at night (LED lighting or florescent lighting or w/e)

Potential drawback:
- high cost for installation (mostly the glass canopy and supporting structure)

  • First we need to know what we are protecting ourselves from, and what does it mean to be insecure.
    • Insecurity and fear results from absence of knowledge, from the unknown.
    • Criminals hides their identity
  • There are 2 different ways to gain security
    • First is to increase the division between familiarity and the unknown. Setting up boundaries and gates in a process of self-denial. “What we do not know does not harm us”. Example: a castle, a stronghold, imperial China (the great wall)
    • Second way is to be curious and actively gain understanding of the unknown: progress. Example: Columbus, human race as a whole, if we know everything there is to know about something, than it doesn’t scare us anymore
  • Rather than dealing with the act of prevention and denial of access, security here is represented by an increase in self-awareness prior to gaining awareness of the surrounding,
  • Self-awareness is achieved through self-reflection, the ability to locate one’s self in a certain situation/context/and in relation to one another.
  • Augmented reality
    • Overlaying digital information onto the physical world
    • Make the physical world transparent, increase social connectiveness and eliminate physical boundaries
  • A system of augmented awareness
    • A layer of street installation
    • Not passive systems, but interactive systems to heighten awareness
    • Register movements, paths, patterns
      • Proximity sensors, motion sensors, heat sensors, sound sensors
    • Provide information through augmented reality
      • Information representation through digital mobile devices
      • Projections
      • LED
      • Sound
      • Make possible/provide convenience to social activities, events

The Project
Focuses on a specific mechanism for increasing self-awareness
Tackling a certain sensory experience


Sargasso Fields – Philip Beesley
A  two-week intensive workshop was staged August 2009 at the Royal Academy of Denmark, led by experimental architects and educators Philip Beesley and Mette Ramsgard Thomsen. The structure was reinstalled in Brussells for the Pluto New Media festival October 2009, and then was re-mounted for the Climate and Architecture exhibition in Copenhagen during the UN Climate Summit COP 15.  
Twenty-five architecture students investigated primary qualities of a responsive, sensitive architecture through cycles of making and designing.  The expanded, lightweight layers within this kinetic field are organized like a coral reef, as densely massed organisms Calls and responses ripple throughout this environment, stirring diffuse ripples of filtered air that trickle through the space.Power cells arrayed within a bamboo and silk ‘geotextile’ array at the lower levels of this stratified environment created their own power, generating small shivers and blinks that call out to the upper ‘parent’ layer of lightweight structure. The lower layer is radically diffuse, acting as a condensation layer that would harvest energy and support renewed fertile growth in the future. Suspended proximity sensors and touch sensors from the upper layer register these weak signals and amplify them through arrays of microprocessor-driven actuated components

Light - Richard Box
FIELD , an installation by Richard Box , an artist in residence in the physics department at the University of Bristol, is a major undertaking which includes the installation of several thousand ready- made glass fluorescent tubes. The tubes are ‘planted’ at the foot of an electricity pylon, and pick up the waste emission from the overhead power line causing the tubes to glow when an electrical voltage is set up across it. The result is a field of light sabers that is just amazing and makes visible what would otherwise go unnoticed.
