    From July - December 2013 Hannah was a researcher at the UdK's Design Research Lab

    From 2010-2012 Mika was a guest researcher in the Smart Textiles Design Lab at The Swedish School of Textiles

    From 2009 - 2011 Hannah was a graduate student in the MIT Media Lab's High-Low Tech research group led by Leah Buechley


    In 2009 Hannah and Mika were both research fellows at the Distance Lab


    Between 2003 - 2009 Hannah and Mika were both students at Interface Cultures
    We support the Open Source Hardware movement. All our own designs published on this website are released under the Free Cultural Works definition

    Soft Interactive Technology at Weissensee

    The second part of the course is about exploring the SMA (shape memory alloy) and textile.
    We will go over how to train the SMA, how to connect them and how you can trigger them with electricity. We will also connect the SMA samples to Arduino and control the activation with it.

    The first SMA smocking details are posted here >> https://www.kobakant.at/DIY/?p=6687


    To memorize a shape, SMA needs to be trained. Here is the details on how to train them.
    https://www.kobakant.at/DIY/?p=6682

    and here is how to connect them to thread/ sewing connections

    SMA/ Flexinol Wire 0.010″ LT https://www.robotshop.com/en/dynalloy-flexinol-010-lt-actuator-wire.html


    The first 2 days is about experimenting with embroidered speakers. You will learn how to make a basic embroidered speaker with copper thread, small introduction to arduino and tone library, how to read analog sensors and control the sound with it. You will be also introduced to Sound board where you can trigger MP3 files with sensors and play back from the speaker. The second day is to try out your own design of speakers or to combine with sensors and Arduino code.

    Here is the detailed tutorial on how to make embroidered speaker.

    Electromagnets

    An electromagnet is simply a coil of wire. It is usually wound around an iron core. However, it could be wound around an air core, in which case it is called a solenoid. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet. The polarity of the electromagnet is determined by the direction the current. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (conventional current flows from + to -). The direction your thumb is pointing is the direction of the magnetic field, so north would come out of the electromagnet in the direction of your thumb. DC electromagnets are principally used to pick up or hold objects.
    (from http://www.coolmagnetman.com/magelect.htm)

    An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
    (from https://en.wikipedia.org/wiki/Electromagnet)


    Magnetic field produced by a solenoid (coil of wire). This drawing shows a cross section through the center of the coil. The crosses are wires in which current is moving into the page; the dots are wires in which current is moving up out of the page.


    The magnetic field lines of a current-carrying loop of wire pass through the center of the loop, concentrating the field there

    Arduino

    You can download the Arduino IDE software from here >>
    https://www.arduino.cc/en/Main/Software

    After you install the Arduino, connect the Arduino to your computer and upload the blink example code from File/Examples/Basics/Blink
    https://www.arduino.cc/en/Tutorial/Blink

    Here is the tone() tutorial on Arduino site
    https://www.arduino.cc/en/Tutorial/tonePitchFollower


    The sound board module we used in the course is this one
    Adafruit Audio FX Mini Sound Board – WAV/OGG Trigger 16MB Flash
    https://learn.adafruit.com/adafruit-audio-fx-sound-board/overview

    You will need a library to use it with Arduino. you can download it from here, then use library manager/ open zip file from your Arduino.
    https://github.com/adafruit/Adafruit_Soundboard_library

    If you want to get sound samples, you can find free sound samples from here.
    free sound >> https://freesound.org/

    If you wanted to try more advanced synthesis on Arduino, you can try Mozzi library
    https://sensorium.github.io/Mozzi/

    To connect analog sensors (resistive textile material as sensors) you need to create voltage divider circuit. here is the detials >> https://www.kobakant.at/DIY/?p=6102
