TheAncientOne Posted July 31, 2007 Report Share Posted July 31, 2007 Ah yes - looks like and HP inkjet horizontal positioner strip.The higher end old ones have a precision slotted metal strip instead.

I did a circular cyclic grey code one once too, for a sort of digital compass, (then I discovered fluxgates).Mike Quote Link to comment Share on other sites More sharing options...
