WatchOut

about

The WatchOut!-Synthesizer makes sound due to a program on an attiny13-chip! Dependent on the light intensity, a solarpanel reads this program and gives the power for the sound production. The more light shines on the cell, the higher the pitch and louder the sound. There are different programs which defines the function of the two buttons. Because of the inconstant power-source the processing of attiny13 is very unstable, which actually gives us nice sounds! <br\> <br\>

The idea to have a synthesizer at the wrist was developed as a souvenir for the JurassicLaboratory Electronic-Music-Festival in Lucerne, Switzerland: <br\> http://wiki.sgmk-ssam.ch/index.php/I <br\> http://wiki.sgmk-ssam.ch/index.php/II <br\> http://wiki.sgmk-ssam.ch/index.php/Three <br\>
