IR Quadrature Incremental Encoder for Arcade Joysticks
  WIP - Here, I tried to add rotation to standard arcade joysticks for games requiring this feature.
Shown here is only a PROTOTYPE, but a later Arduino microcontroller version proved the paticular IR receiver SOC's used to be a poor choice due some internal normalizing (AVC) feature.  But here, you can at least see my analog/passive circuit attempt.
