Scuttlebut is a simple noise generator with a built-in mini sequencer. It's an experiment in minimalism to see how much could be squeezed from a simple 8-pin 8-bit microcontroller with minimal audio circuitry. It's easy to build - designed in fact for a soldering workshop for beginners - and only uses through-hole components.

The user controls are a couple of rotary presets, a pair of pushbuttons, a touch pad and a light sensor. The presets control a pair of oscillators and the pushbuttons select waveforms (sine, triangle, sawtooth etc.) and modulation (frequency, amplitude, phase etc.). The touch pad activates the light sensor which then further modulates the sound.

Includes a record mode in which a sequence of different sounds can be recorded and then looped back.

Supplied as a kit of PCB and components. Power input is via a 9V PP3 battery snap and audio output is mono through a 3.5mm jack socket.
