MemPot, potentiometer with a memory

MemPot is a small controller circuit where potentiometer (or any variable resisor) is read and recorded with PIC (16F819) microcontroller. PIC stores a sequence of values from the user turning the knob and plays the same sequence back via serially controlled digital potentiometer (DS1267) chip. The playback speed and recording buffer can be controlled. This is a handy tool for performing gestures with electronic instruments with variable resistors as controllers.

Check the updates on schematics, PCB-files and Bill of Materials from here. We can hopefully include the making of MemPot for our next DRU workshop in July.
