[Tim] sent us his Noise Box Synth. The box is a sixteen step synthesizer that can generate sine, square, triangle, and sawtooth waves as well as a collection of sound effects (video after the break). The hardware is simple; an Arduino, four potentiometers, four buttons, a switch, a speaker, and some LEDs. This was a gift for a three-year-old but we’d be just as happy unwrapping it ourselves. We didn’t find a schematic but all of the connections and hardware can be extrapolated from the source code.
Arduino sometimes gets a bad name around here. This project, [Tim's] first that uses Arduino, proves that the accessibility of the platform makes it possible to jump directly into the deep end. Catch the video after the break. [Read more...]
