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?
