    The following institutions have funded our research and supported our work:

    Since 2020, Hannah is guest professor of the Spiel&&Objekt Master's program at the University of Performing Arts Ernst Busch in Berlin

    From 2013-2015 Mika was a guest professor at the eLab at Kunsthochschule Berlin-Weissensee

    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
    Example Projects

    Lulu optic fiber swatches

    Swatches that showcase some of the things you can do with the Lulu Daisy – a design solution to connecting e-textiles, LEDs and optic-fibers.

    – 3 swatches
    – 6 mini crocodile clips
    – 1 breadboard with Teensy and crocodile clip connections for (+3V, GND, Data)

    Lulu Bumblebee demo swatches

    demo code:
    cycles through one swatch at a time. was done very quickly, could be improved….
    >> https://github.com/eTextile/Lulu/blob/master/Software/Arduino/Lulu_daisySwatch/Lulu_daisySwatch.ino


    1)”hello world”

    uses 1.5mm diameter sideglow optic fiber to write text.
    code fades between “hello” and “world” revealing one at a time. without the light you can not read what it says.

    2)”future fungus”

    uses 2mm diameter sideglow optic fiber inserted into edging. the optic fiber functions both as illuminating material as well as rigid frame that causes the fabric to curve/curl in organic shapes.
    code fades LED at either end of the optic-fiber to demonstrate colour-mixing.

    3)”tilt data”

    the data-pin of the LEDs is broken out to petals of conductive fabric. the data coming from the microcontroller flows into the central bead and only affects the LED whose petal it is resting on.
    demos 1.5mm, 2mm and 3mm diameter sideglow optic fiber without the cladding, showing effects of cutting into the core to create illumination artefacts.
    code fades between colours.

    The board that controls it all:

    IMPORTANT:
    – do not power the swatches with 5V!!! only power from the +3V of the Teensy!
    – the crocodile clips between the swatches should be: top=+3V, middle=GND, bottom=Data
    – mount the swatches in the following order: 1)”hello world”, 2)”future fungus”, 3)”tilt data”
