I did this demo video earlier this year while developing the spray can for my thesis project. The RGB LED wasn’t bright enough so I replaced it with a super bright one later on and moved it to the top of the can to lighten up the donut.

With the release of Processing 1.0 last week, the Processing team developed a set of library guidelines and a html template for creating a online summary page. To comply with these new requirements I updated the AmbientLightSensor Library.

Digital Graffiti – A Subculture Conquers Interactive Worlds

Finally I delivered my thesis project I did in cooperation with Less Rain. The subject was »Digital Graffiti – A Subculture Conquers Interactive Worlds« and it’s all about experimenting with different input devices for a physical, digital graffiti installation. The result is an Adobe AIR application using either the computer mouse, the Nintendo Wiimote or »VandalSpray« to paint digital canvases. VandalSpray is a digital spray can specifically designed for this purpose. It implements the attributes of a real spray can or at least trys to achieve them as natural as possible. Except a turnable bottom for changing the color, VandalSpray has no other interfacing elements than its real counterpart and therefore you don’t have to learn and explore the functionality first, because you intuitively know how to use it.

VandalSpray features includes:

• exchangeable caps
• color display
• digital valve system to vary the amount of »paint« coming out of the cap
• different colors
• wireless

The spray can is built upon the Arduino platform and uses different sensors and electronic modules like a RFID reader, a super bright RGB LED, a Rotary Encoder, a Bluetooth module, a force sensitive resitor (FSR) and loads of wires and solder to implement the desired behavior. For tracking the spray can I use a Wiimote and the WiiFlash ActionScript 3 library and server, but this could also be replaced by a standard webcam and an adequate tracking implementation.
Because I didn’t want to put some kind of speaker in the spray can (there was no space left anyway) the spray sound is generated from the AIR app and output on the speakers of the notebook.

Portfolio Moved

October 23rd, 2008 • General, Projects

As there is no real backend, my old portfolio site is quite hard to update, so I decided to move the portfolio temporarily to this blog until i have the time to go for new flash site. You can find a small selection of projects here.

One of my latest projects just launched last week. It’s a portfolio site for visual artist and interface designer stereosucker aka Tine Päch.

The site is completely dynamic and provides deep linking and browser button support through SWFAddress.
