Re-imagining the exiting
Hyungkoo Lee, Altering features
The helmet-like wearable sculptures, merge the worlds of sociology and biology into a strange and unnerving mix. Lee’s ‘helmet’ contains spaces for interchangeable lenses which can alternately emphasize or minimize various facial features. The lenses can produce disturbingly exaggerated facial expressions, faces that are cartoonishly demure or aggressive. Lee’s series underscores the body’s important role in social life and everyday flows of power. Engineered to optically exaggerate facial and bodily features, the series was initiated in an attempt to overcome the “undersized Asian male complex” the artist claims he suffered from while completing his MFA at Yale.

Carsten Holler, Upside down glasses
The goggles are based on an experiment carried out by George Stratton in the 1890s. While studying the perception in vision, the psychologist wore special glasses which inverted images up and down and left and right. He found that after 4 days wearing them continuously, his brain started to compensate, and he could see the world the right way up again.
Niklas Roy, We be cyborgs
“A cyborg, short for ‘cybernetic organism’, is a being with both organic and artificial parts.”
Niklas Roy writes about the workshop and the decision to use low-fi materials: "Regarding the cyborg building materials, we decided to leave computers and electronics out. Instead, we relied on post-apocalyptic plastic trash from one Euro shops, some medical gear and plenty of useful things from the hardware store around the corner"

Lucyandbart, Low tech plastic surgery
LucyandBart's a low – tech prosthetic way for human enhancement.
Soomi Park, The LED Eyelash
LINK to project This project is brought into the world from a simple question: Why do women want larger and bigger eyes? Asian women tend to have stronger needs for bigger eyes as a standard of beauty, but relatively few of them are born with naturally big eyes. Those without big eyes can only look for alternative ways to make their eyes look prettier, i.e., larger, by using a repertoire of skills such as putting on makeup and wearing jewellery. Sometimes, the desires for bigger eyes can become almost obsessive, and many women opt for plastic surgery in order to make their dream come true: I call this, the fetish of Big Eyes.

Mis-using the body
Ann Hamilton, Face to Face
The artist uses her own mouth as a pinhole camera. The resulting images of faces and landscapes are strangely distorted, the curvature of her lips forming a shape that almost resembles an eye.
Arthur Elsenaar (1962) is a performance artist, former radio pirate and facial hacker from the Netherlands. Elsenaar is fascinated by the intimate relationship of electricity and the human body and is the originator of electro-facial choreography.

Jacobson’s Fabulous Olfactometer LINK to video
It is a sensorial prosthesis for extreme environments inspired by a sense organ called “Jacobson’s organ” that enables certain animals to sense odourless chemicals. Two sensors worn at the forehead register small particles and CO2 levels. When a dangerous threshold is overridden, gears are set in motion and the upper lip is pulled upwards to modify the wearer’s face similar to an animal behaviour called “flehmen”.
Automated Anchoring Armour
AAA holds a promise of continuous psychological intervention. The psychological treatment is worn as physical armour on the body and the skin becomes an interface to mental well-being. When a biosensor on the palm receives a signal of increased stress, the mechanism comes into action: A tap is repeatedly given to the forearm and thus aims to trigger a positive memory linked to this physical sensation. Its exaggerated physical shape amplifies the notion of a protective equipment.
The Constitute studio, EYEsect
EYESECT is a wearable interactive installation that reflects an Out-of-Bodiment in an immersive way. By this it allows users to experience their environemts from new points of view. The world, as we perceive in reality and through media is aligned to binocular and stereoscopic vision of human beings. These omnipresent human-centristic perspectives and the critical debate about contemporary 3D Technology that only simulates real space and does not stimulate the lust for new and curiosity were the initial point from where the work on EYESECT began. The Question: “How do we not see” and the fascination for cybernetic – spirtual utopias, Science Fiction and bionic experiments lead to the development of one helmet device and two freely attachable camera eyes

weeks 4 and 5:
Breathe in, breathe out
what is the Arduino
Hello everyone hello hello hello,
now what is an Arduino ...well...find a detailed introduction here []
Computer and processor are generic terms for the anything that can run a program, basically.
Controller or microcontroller usually refers to a simple processor that does only one task, like listening to sensors. In explaining microcontrollers, we’ll distinguish them from computers, which contain more powerful processors that can run an operating system.
Arduino is an open source physical computing platform based on a simple input/output (I/O) board and a development environment that implements the Processing language. Arduino can be used to develop standalone interactive objects or can be connected to software on your computer.
The Arduino contains a microcontroller.
Most electronic devices today have a microcontroller at their core. Microcontrollers are optimized for control of general input and output. What Is Physical Computing? Physical Computing uses electronics to prototype new materials for ( in our case ) designers and artists.
Arduino is composed of two major parts: the Arduino board, which is the piece of hardware you work on when you build your objects; and the Arduino IDE, the piece of software you run on your computer. You use the IDE to create a sketch (a little computer program) that you upload to the Arduino board. The sketch tells the board what to do.
In the meantime, HERE you can find ANYTHING about Arduino, including download the software
The pins on your Arduino are the places where you connect wires to construct a circuit (probably in conjunction with a breadboard and some wire. They usually have black plastic ‘headers’ that allow you to just plug a wire right into the board. The Arduino has several different kinds of pins, each of which is labeled on the board and used for different functions.
First things first
we start by figuring put if our Arduino is all good or it is somehow damaged ...it is a basic test to check and run a simple script at the same time.
so we have something like this
GOOOD! lets dissect this
- commenting / one line and multiple lines
Lets compile this
Lets upload this
And we should have a Blinking aka Flashing on board LED
Inputs and Outputs
Like mentioned earlier - μControllers are optimized for control of general input and output. What are those two exactly.
Analog ( we have six of them in the Uno): The area of pins under the ‘Analog In’ label (A0 through A5 on the UNO) are Analog In pins. These pins can read the signal from an analog sensor (like a temperature sensor) and convert it into a digital value that we can read.
Digital (seven on the Uno): Across from the analog pins are the digital pins (0 through 13 on the UNO). These pins can be used for both digital input (like telling if a button is pushed) and digital output (like powering an LED).
Digital sensors are the sensors that gives 2 state (on/off, 5V/0V). You will connect them to digital Pins and set it as INPUT.
Digital data consists exclusively of 0s and 1s .
For example, consider a push button switch. This is one of the simplest forms of sensors. It has two discrete values. It is on, or it is off. Other 'discrete' sensors might provide you with a binary value.
Another example of a digital sensor is an accelerometer, which sends a series of data points (speed, direction, and so on) to the Arduino. Usually digital sensors need a chip in the sensor to interpret the physical data.
Analog sensors on the other hand, gives range. You connect this types of Analog sensors to Analog Input pins which is measuring the incoming voltage between 0V-5V*. Arduino converts this incoming voltage into the number between 0-1023.
Analog data is transmitted as a continuous signal, almost like a wave. In other words, an analog sensor doesn’t send a burst of 1s and 0s like digital sensors do; instead, the sensor modulates a continuous signal to transmit data.
Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volts, it understands zero volts (0V) as a binary 0 and a five volts (5V) as a binary 1. The world however is not so simple and likes to use shades of gray. What if the signal is 2.72V? Is that a zero or a one? We often need to measure signals that vary; these are called analog signals. A 5V analog sensor may output 0.01V or 4.99V or anything inbetween. Luckily, nearly all microcontrollers have a device built into them that allows us to convert these voltages into values that we can use in a program to make a decision.
An Analog to Digital Converter (ADC) is a very useful feature that converts an analog voltage on a pin to a digital number. By converting from the analog world to the digital world, we can begin to use electronics to interface to the analog world around us.
Not every pin on a microcontroller has the ability to do analog to digital conversions. On the Arduino board, these pins have an ‘A’ in front of their label (A0 through A5) to indicate these pins can read analog voltages.
ADCs can vary greatly between microcontroller. The ADC on the Arduino is a 10-bit ADC meaning it has the ability to detect 1,024 (210) discrete analog levels. Some microcontrollers have 8-bit ADCs (28 = 256 discrete levels) and some have 16-bit ADCs (216 = 65,536 discrete levels).
case study: Stretch Sensor
As a main actor of today we will take the conductive rubber.
Hooked up to two alligator clips we create a simple resistive sensor.
Analog Voltage Reading Method The easiest way to measure a resistive sensor is to connect one end to Power and the other to a pull-down resistor to ground. Then the point between the fixed pulldown resistor and the variable resistor ( conductive rubber) is connected to the analog input of a microcontroller such as the Arduino.
OK, wait...the BREADBOARD
This terminology goes way back in the days.
Generally, you would mount electronic components to a piece of wood (the actual "breadboard"), and do all the wiring with point-point wire and the components just hanging between the various devices.
The story goes that an engineer had an idea for a vacuum tube device late one night. Looking around the house, the only base for his prototype that he found was indeed his wife's breadboard, from the breadbox.
A video by the Make magazine people
Ok, but why do we need to breadboard?
Well, they are useful for making temporary circuits and prototyping, and they require absolutely no soldering.
Prototyping is the process of testing out an idea by creating a preliminary model from which other forms are developed or copied, and it is one of the most common uses for breadboards.
The best way to explain how a breadboard works is to take it apart and see what’s inside.
connections lines are connected like this
So lets do it
get some data from it
now lets add an Output
