Use at your own risk
The new version of sculpTon will be premiered at the exhibition "Use at your own risk" at the Ars Electronica Festival 2013.
I’m working on the software part of the project.
Everything is developed in Pd (Pure Data) and for now is running on my Mac Book
Here a first screenshot:
I designed this box (similar to a guitar pedal) for live performances ad demos.
This is half of the brain of sculpTon.
The object is connected to this box, which include an Arduino Mega, a shield designed for this project, audio output and serial communication/power through USB.
And a foot switch, very useful: now I can calibrate the IMU during a performance.
Modular structure and sensors
I’m working on the creation of some modules (a kind of muscles) for the structure of the object.
I tried to embed my sensors into some 3d printed little masses.

Space, motion, orientation
After some experiments with analog accelerometers and digital gyroscopes I found out that the best solution for sensing motion and orientation is using an IMU (Inertial Measurement Unit).
I want to recommend two things:

sculpTon - second iteration
With the second version of the object I’m trying to work more on the idea of a modular structure, add a motion sensor, developing the haptic qualities.
Last but not least, create a stable and robust object.
The space, the vibrations: inside/outside
I decide to put a little electrect microphone in my object.
For two reasons:
- capturing the sound from the inside of the object
- establish a sonic relation between the object and the environment
- with the help of some signal processing use the microphone like an additional powerful sensor
