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
