Eagle demands the .1 spacing too, and I was not able to turn that off when I made the board for the lathe. So I may as well use the perboard with the solder rings. Playing in the night now, a 66 cycle disk is looking about right. So that will be the next attempt. > You could glue them into holes in a non-plated board and solder wires > to the legs. > > This seems less trouble than making a new wheel to match 0.1" spacing. > > Alternatively mount A&Z on a different board to B and mount B on > slotted holes. 5.25 spacings is nearly as good as 1.25 spacings. (the > further apart the optos get the more you notice imperfections in your > disc) Currently 6.5 slots in .6" (center to center, eg the active marks on the opto's. 264 edges per rev for a 1.36363636364 degree spacing) Currently, a unit using two holes, skip a hole, another unit, skip a hole & insert the 3rd one.
