      How about putting a long bolt on the end of a motor shaft. Attach
      motor to collar bone and nut (threaded rod coupler is better) to head. A
      linear pot for feedback and you have a linear servo. (A string wrapped
      around the shaft of a ten turn pot could also substitute for the linear pot.)
      If your computer has analog input, you can use it to directly drive an H
      bridge.

      Just a thought
