  2. Environmental Lifecycle Analysis • Product Manufacture • PCB and IC production w/ hazardous chemicals • Unavoidable without industry wide shift • Plastics used in SSR and casing • Due to choice of ZigBit, no control over its production. • Use RoHS components.

  3. Stage: Normal Use • Standby power: • Approximately 100 mW • Could be reduced with radio sleep mode • Meets objectives of One Watt Initiative and E.U. E.C. Regulation 1275/2008 • USB and shade module PSU > 90% efficiency • Other PSUs could be made > 90% efficient • ISM spectrum crowding • HomeKinection for a “smart” home

  4. Stage: Disposal • Usual electronic waste issues • Small, distributed modules • Requires effort to collect and dispose • Conceivably tens to hundreds of modules per house • Use RoHS • Attach labels to each module describing proper disposal methods

  5. Ethical Concerns • Increased spotlight on manufacturing ethics • See Foxconn “sweatshop” issues • Could/should choose an ethical manufacturer? • Other business ethical considerations

  6. Safety Ethics • Dimmer module • Only compatible with incandescent lights • Safely integrate with variety of lights? • e.g. plug type, warning labels • IR module • Avoid increasing volume out of control • Test overheating of module in A/V cabinet

  7. Safety Ethics • Shade module • Very simple and incapable of damage • Health of indoor occupants (lack of sunlight) • USB HID • Could the device short or over-load USB port? • Command module • Overheating • Custom case and power solution • What happens when communications link down?

  8. Safety Ethics • System view • Does our system promote slothfulness? • One step closer to Wall-E type future? • Wireless spectrum limited • Failures in system communication • Should lights stay on or turn off upon failure? • Could USB HID run “rm –rf /” (or equivalent) • Should there be authorized users?
