Spinning sounds with the Servo Seq

Gijs Gieskes introduces another intriguing musical machine, the opto-sensing multi-armed Servo Seq –

The frequency circles speed can be set with a pot on the controller.
The arms can be sequenced with the three buttons on the controller, in combination with the joystick.. If the joystick is moved up, the volume will go up for the arm that is being controlled. Moving the joystick left and right will change the position of the arm.
On the tip of the arm there is a line detector, that plays back the frequencys, but the arms can also hit objects placed next to the circle to make drum sounds.

The Seq’s brain consists of an ATMega168 configured as an Arduino compatible – more info, code and even a web app for generating compatible disc patterns are all available on the relevant project page. [via Create Digital Music]
