Prankophone  is the new interactive installation by Dmitry Morozov (his amazing projects have been featured on this blog ).  This time he created  a sound object, a hybrid of synthesizer, telephone and logic module:

The main principle of the object’s functioning is as follows: depending on the current mode, the apparatus calls to random or pre-defined recipients and plays them algorithmic melodies created from their phone numbers. The speakers transmit both the synthesized sounds and the sound from answering person. The common sound layer is involving a random recipient who doesn’t suspect anything. The person who answers the phone can’t hear any other sounds except for the synthesized ones.

You can play with it in 4 different modes:

– Autonomous mode –  it generates the numbers by itself and tries to reach them, and play them the sounds.
– Manual mode – when you dial any number by pressing standard phone keys it gets automatically transformed into sounds.
– Keyboard mode – mode of dialing the number on the one-octave keyboard where 10 keys correspond to 10 digits.
– Live mode – the number is defined by any of the previous methods, but the sounds are reproduced not automatically but from the keyboard, thus the user may “communicate” through sound with the person who answered.
It runs on Arduino Mega and you can listen to its sounds on the following video:

Cata Sopros is interactive sound installation running on Arduino Uno and created by Elas Duas, a multidisciplinary studio based in the city of Guimarães (Portugal). If you translate the title from portuguese it means: Breathe Catchers. In fact the project is a collective musical instrument made with paper windmills transforming the users’ breathe into sounds:

The windmills have inbuilt electret microphones that were connected to an Arduino Uno. The sensor data was then sent to MaxMSP and the sounds were played with Ableton Live. The video was shot at the cloister of the beautiful Alberto Sampaio museum in Guimarães, Portugal.

Enjoy the video:

Variations II of Variations II is a kinetic sculpture inspired by John Cage’s Variations series.

Cage’s Variations II is a graphical composition that generates musical events using measurements of distance between dots and lines on a piece of paper.

The instructions for the piece determine the behavior of rotating panels and images synchronized to be projected onto the sculpture. Motors drive the rotation of the panels, and are used as a sound source for the audio portion of this piece.

The artist Jay Kim has used C/C++,  Arduino,  MaxMSP/Jitter and some stepper motor to create his sculpture.
