  1. Ethical and Environmental Impact Analysis Team 17 Tone Matrix Music Box Presented by: ChiaSiongGoh

  2. Project Overview An 8x8 grid-based music synthesizer made with a button pad at the top and some LEDs at the bottom Parts related to environmental issues: PCB, LCD and li-poly battery

  3. Environmental Issues • PCB • Use of hazardous chemicals during production • Contains precious metals (Cu, Sn) • Get supply only from trusted manufacturers with proper care on manufacturing process • Recycle PCB to recover precious metals

  4. Environmental Issues • LCD • Emission of greenhouse gas nitrogen trifluoride (NF3) • “17,000 times stronger than that of carbon dioxide” • Extend product overall lifespan

  5. Environmental Issues • Li-poly battery • Contamination to environment if dumped improperly • List out potential effects of improper handling on user manual • Encourage recycling by providing the nearest center for recycling • http://www.call2recycle.org/

  6. Ethical Challenges • Reliability of the product • Test of product under various conditions • Choosing only RoHS compliant ICs & solders

  7. Ethical Challenges • Fail-proof mechanism • Have a diode between battery output and wall-wart output • Warning of malfunctioning • Provide a list FAQs and troubleshooting methods

  8. Questions and Comments?
