Dialight Countdown Pedestrian Signal Final Installation

I picked up this Dialight 430-6479-001F Countdown Pedestrian Signal at a surplus store in Florida last year and thought it would be cool to get it working and mount it in my house.

I used a BASIC Stamp II with EFK-TEK RC-4 SSR board to switch on and off the four control lines (AC hot) from the independent icon and timer modules on the signal. Upon power-up, the countdown timer enters a "learning phase." The timer is programmed by flashing the Upraised Hand icon (whose hot is joined with a hot of the timer module). During the learning phase, the timer side is blank. On subsequent cycles, the correct countdown time is displayed.
