  1. Environmental Impact Team 20 Marble Maze Justin Spencer

  2. Abstract Our team is implementing a smartphone controlled marble maze. Players guide a marble through a maze by controlling the degree of tilt of the playing surface via a wireless link to a smartphone. The accelerometers in the smartphone capture the players' input and relay it to the game controller. The game controller then adjusts the tilt of the playing surface via stepper motors on each axis.

  3. Components • iPhone • player input • Rasberry Pi • WiFi access point • Custom PCB • game logic & motor control • Stepper motors • position playing surface • Marble Labyrinth • game chassis

  4. Life-Cycle • Manufacture • iPhone, Rasberry Pi, PCB, motors, maze • Transport • China (iPhone), UK (Rpi), Sweden (maze) • Assembly • Service Life • Disposal • Recyclables - maze chassis (wood), misc. plastic, misc. metal • Waste - Rasberry Pi, PCB, motors, wiring

  5. Impact • Resources Used • Wood - maze chassis • Plastic - maze parts, Rpi case • Metal - motors, maze control rods, hardware, copper conductors • Electricity - during manufacture and use • Waste Created • Packaging materials from sub-components • Pollution from transportation • Hazardous chemicals used in electronics manufacture (formaldehyde, dimethylformamide, and lead)

  6. Improvements • Use sustainable source of wood • Incorporate Rpi functionality into PCB • Reduce PCB parts count and decrease PCB size • Use all RoHS & lead-free components • Make device easy to dissassmble for disposal • Place device in low-power sleep mode after a time-out
