   Am thinking about building an electronic sextant that would provide near   
   centimeter accuracy.  This would mean a degree should be partitioned to   
   about 400,000 steps.  Was considering using a pot and 5v to feed an A/D   
   but on reflection think that a single turn pot would not be clean enough   
   for that many steps.  Would someone confirm this for me.  Use of a   
   multi-turn pot requires gears which would be too expensive due to their   
   very critical meshing needed.  Thanx, Ron
