To operate the camera a OSC command has to be sent setup like /camera command number number is usually an integer but sometimes a float number, as explained together with the commands below. For instance to switch the camera on, you have to send

Embedded Art System (EAS) Malte Steiner and Wolfgang Spahn are exploring the artistic potential of embedded open source systems. This platform gives the possibility to combine quite a lot of independent devices to create a more powerful system than most single computers can provide. Open Source and Open Hardware gives the possibility to access all resources of the used embedded systems, to build a network with full control at the same time.

HDMI Mode Change the HDMI mode to a DMT 3D grafics in Open GL and the OMXPlayer sometimes run into conflicts and the HDMI output stops. The best solution until now is to set the HDMI mode in the configuration file on “mode_groupe=2”. That means the Raspberry Pi starts allways in an DMT mode (Monitor Mode) and not in an CEA mode (TV Mode).

Embedded Artist Industrial noise and digital sound processing meets multi space projections: “Embedded Artist” is a media performance by Malte Steiner and Wolfgang Spahn. For the performances and installations both artists developed the Embedded Art System, a multi visual modular system based on the Raspberry Pi. In addition to digital sound syntheses the electro-magnetic pollution of the used gear- and servo-motors creates an unique sound composition.
