Metal Race Combines Operation And Calculator Game


[Greg] was feeling nostalgic about the game RACE for to TI-83 graphing calculator. In the game, your car is stationary with controls to move the scrolling maze from side to side in order to avoid a crash. He set out to build a physical version of the game with a don’t-touch-the-side concept that reminds us of Operation.

The game board is a wire frame constructed from paperclips then attached to a motorized frame. The vehicle is also metal and is attached to the lens sled from a scrapped CD-ROM drive. The maze scrolls from left to right with up and down vehicle motion controlled by two arcade buttons. An Arduino controls the motors and monitors the button inputs. He has plans to add a buzzer that sounds when the metal car “crashes” in to the wire walls of the maze. We’ve embedded video of the working game after the break. For more build photos take a look at his flickr set.[youtube=]

  1. I’m amazed this uses an Arduino when the job could be done with, basically, a few pieces of wire! Perhaps a transistor or two for a latch if you wanted the game to stop when you hit the side.

    Or even better, do it the way they did it in arcades in the 1970s. Basically a light sensor, and track made from transparent film to detect collision.

    OTOH this project is mostly mechanical, which makes it a shame that it only “kinda” works! It would be nice and novel to see it working as a cute mechanical game, it’s nice when people use ingenuity to get the most out of something simple, rather than just throwing MIPS at it. The mechanical aspect alone is the impressive factor.
