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!
The idea to have a synthesizer at the wrist was developed as a souvenir for the JurassicLaboratory Electronic-Music-Festival in Lucerne, Switzerland:
To upload a new code use the following tools:
Mac: Terminal, avrdude http://www.ladyada.net/learn/avr/avrdude.html
Or: Arduino: http://arduino.cc/en/Tutorial/ArduinoISP with a breadboard
final code is coming soon... or look up at thingiverse: http://www.thingiverse.com/thing:37478
1 100uF Capacitor
1 ATtiny13 with socket
1 Minijack socket
1 Piezo loudspeaker
Wire (for solarpanel)
ATtiny13, the old version! Don't use the AtTiny13A, it works only with the one without the "A". ATtiny13
2 M4 Screws
2 M4 Nuts
1 Acrylic deck
1 Acrylic base with
laserfiles coming soon or look up at: http://www.thingiverse.com/thing:37478
Keep attention by removing the chip, to not break the legs. And WatchOut! by soldering the solar panel...
