Available as an assembled Module and as a DIY project.
This Module is currently available.
A reverse DC motor
CV OUT: Rotating right gives positive voltage on the CV output, and rotating left will give a negative voltage, no rotation will give 0 volt. The faster you rotate the higher the voltage will be.
AUDIO OUT: The faster you rotate the higher the pitch and the higher the volume will be. But the volume is clipped by diodes to never go over around 5v peak to peak.
POTMETER: Adjust the range of the output signal. on the audio out it will also set the amount of clipping by the diodes (distortion).

These merchants probably sell this module. Huh?
