Anyone can learn to solder! And anyone can learn to make music, sound (and noise!) with computer chips! All participants will easily learn all of this by making an ArduTouch music synthesizer from an open hardware kit. This workshop is for everyone -- even total beginners. ArduTouch is designed for total beginners to learn to solder, as well as to learn Digital Signal Processing for making sound. It is called ArduTouch because it is based on Arduino, and it has a touch keyboard. It also has a built-in speaker/amp, so you can play/perform wherever you go. ArduTouch comes pre-programmed with a way nice 4-voice sawtooth waveform, but can be easily re-programmed with other way different synths, including already available drums, drones, noise, arpegios, and more; or with synths of your own making. Under-16s must be accompanied by an adult, and both must have a ticket for this workshop.
