I like video games, Halloween, and making "stuff", so this year I combined all three and created a 'Dead-icated' Splatterhouse arcade game to go in our arcade for the Halloween season (Ground Kontrol Classic Arcade). Aside from just making a unique looking cabinet, I wanted some real-world reactions to in game events-- so I built a daughterboard that taps in to the MC6809 main CPU of the arcade game that sniffs out in-game variables and drives LED lighting in the cabinet in realtime. I had bigger plans for more 'physical' reactions (the board has 13 possible outputs with four PWM channels and nine 'on/off' type current sinks), but ran out of time. The LEDs alone look pretty good though.
The project took several weeks of on and off work, with the last week being pretty much a full time job. Below are the results as well as detailed "what I did" pages for various pieces.
Main set of pictures are below, plus these subsections:
