  • A group of coworkers play board games during lunch, but the author wanted to play Hungry Hungry Hippos instead.
  • The author built circuitry to automate the game using a W65C265SXB microprocessor and 65C816 assembly.
  • Image processing was done with a Sony Playstation 3 camera and C++ code on an Intel Atom netbook.
  • The hippos were later made controllable via Amazon's Alexa using an ElectricImp.
  • The hardest part was configuring motors to pull the levers effectively, with the PowerHD 6001HB servo being the most effective.
  • Image processing involved detecting the board's blue color, finding hippo heads, and identifying balls in front of them.
  • The project did not use OpenCV; the author wrote custom algorithms.
  • The W65C265SXB board was chosen for ease of development, reusing code from the PANCAKE-ROM project.
  • Alexa integration required setting up an internet endpoint via the ElectricImp, similar to a previous project (Alexa TV Remote).
  • Videos and pictures showcase the autoplay functionality and the setup, including the electronics and camera.
