Why don't you close the loop and have proper position feedback ?


I was working with whatever bits and pieces were to hand. Any suggestions on
how to provide a positional feedback loop with typical junkbox items would
be cool. Come to think of it....there is a component in the VCR that *may*
be a linear position sensor..possibly for mechanically detecting how much
tape was remaining on a reel during fast rewind. Not sure of the resolution,
though. Any other ideas?
