it really isnt that hard. all you need is crazy glue, a small screwdriver sharp knife, and tweezers. take gears out w/ tweezer so they arent contaminated and place them on a clean surface. then saw the pot off using the scissors. make sure there are no burs as to not interrupt the gears when they are spinning. send the signal through the microcontroller to the servo. use tweezers to turn pot until gear stops. crazy glue it in place, then put servo back together. very simple.
