This is an open-source, home didactic project, for a cheap magic box able to control the volume of two audio lines via an expression/volume pedal. The pedal wires are decoupled from the audio lines by a digital potentiometer driven by a PIC. The PIC is programmed to scan at fixed frequency the pedal potentiometer value, then reproduces it on the digital potentiometer wires.
- 9V AC/DC power plug for external power supply
- Two mono audio line input and output connector
- Expression/Volume pedal connector
- Switch-array planned for future features
