The workshop:

In this workshop you will be playing with projections on graphite murals – connected interactively over an Arduino micro controller. Graphite can be used to draw on paper or walls. At the same time graphite is conductive and can therefore be used as an interface. When you touch the graphite drawing on the wall it can e.g. serve as a switch or analog sensor connected to an Arduino board through an electric circuit.

With graphite drawings on the wall we can trigger LEDs within the tiny DIY projectors. The projectors can only project one single frame, but many DIY projectors triggered in a row can give the illusion of animated images. The addition of a layer of projected images to the graphite drawings on the wall can give those drawings a new meaning.

DIY projector:

The DIY projector was invented by Philipp Tiefenbacher: all parts and instructions are available on Moddr_ will provide all the parts and pieces for building and mounting the projector, but not the actual image to be projected. The participants in the workshop can experiment with the construction of the DIY projector and the choice of images for the animation. The sequential display of the projected images should implement some sort of storytelling.

The interface part of the installation will consist of one simple graphite line for each projector, serving as a switch that triggers the LED to go on or off. Participants can tinker DIY switches from everyday conductive materials.


Stefanie will give a little introduction to the Arduino board for those interested. Then we could connect DIY switches from the wall and DIY projectors interactively via Arduino.

about Stefanie Wuschitz:

Stefanie Wuschitz uses interactive technology to build mobile sound and video installations site-specifically, encouraging the construction of unique social and collaborative spaces.

Her current focus is on subversive public art produced by women with wireless technology. She was one of the organizers of the international festival 'Eclectic Tech Carnival' in Umea/Sweden and founder of 'Miss Baltazar's Laboratory'= weekly workshops on Open Source Software, Arduino, art techniques as e.g. laser cutting, wearable technology and circuit building (currently based at Metalab/Vienna) as well as led the following workshops:
Mobile-hack-day, Supersimple Robots Workshop at Letni dilny Cistirna-Prague, XBee Workshop at OKNO Bruesseles, Mobile Processing Workshop, Stockholm, Sweden and many others.

She graduated with honors from the University of Applied Arts Vienna in 2006 and did her Masters at New York University's Interactive Telecommunications Program in 2008.
