AbstractOur 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.
Components
• iPhone• player input
• Rasberry Pi• WiFi access point
• Custom PCB• game logic & motor control
• Stepper motors• position playing surface
• Marble Labyrinth• game chassis
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
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 Createdo Packaging materials from sub-componentso Pollution from transportationo Hazardous chemicals used in electronics
manufacture (formaldehyde, dimethylformamide, and lead)
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
