Treasure Chess ECE 477 Team 2 Parul Schroff Environmental Impact Analysis

Project Overview A voice controlled chess game that can display possible moves for the chess piece selected by the player RGB LED matrix panel to display the chess board and the current state of the game OLED to display other game statistics PIC24EP512GU810 microcontroller for display and game logic, dsPIC33FJ128GP202 for voice recognition

Environmental Impact Analysis Manufacturing Normal Use End of Life

Manufacturing PCB Fabrication involves electroplating, copper plating, lamination, etching, solder mask Extensive use of copper, gold, nickel, silver and other chemicals Washing off uncured resist during the process contaminates water How to Address RoHS compliant manufacturer Lead-free solder

Manufacturing 3.3V and 5V Power Supplies PIC microcontrollers RGB LED matrix panels Organic Light-Emitting Diodes (OLEDs)

Manufacturing Packaging using Acrylic Plastic Involves use of toxic substances Polymerization process How to Address Use an alternate for packaging Careful handling and storage Internal cleaning and neutralization of the toxic fumes before releasing it to the atmosphere

Normal Use External source to power up the game Constant energy dissipation while the game is on No other environmental impact otherwise How to Address Turn the game off when not playing On/Off button – makes it more user friendly

End of Life PCB and other components Non-biodegradable Proper disintegration and recycling of hazardous substances Acrylic Hard to recycle but can be re-used if in good condition
