I hadn't used stripboard for ages until I made Les's Tacho x2. Much more used to the joys of UV boxes, FeCl3 etc. I have now resolved never to use stripboard again. It's just too much hassle checking for shorts between the strips :sad:

ecat's Eagle .brd looks good. Must investigate ...

Just a thought about the design spec. Three features of Les's design that I really liked were

  • the use of the Allegro gear sensor (it's as good as gold; no messing with slotted discs/foil/Tipp-Ex etc, very reliable, very robust -- just needs to be mounted tangentially 1-2mm from teeth)
  • the capacity to accommodate a non-standard number of pulses per rev (65 in the case of the ml7 bullwheel)
  • a one pulse per rev output (useful for my Shumatech DRO's).
