An ability to achieve different levels of roasting based on user input. An ability to detect the temperature of the beans. An ability to monitor the color of the beans An ability to interact with the user via GUI An ability to shut off the device if unusual conditions (high temperatures, unusual color in roasting area) are detected.

Teledyne AC relay RoHS in transition Radioshack Transformer is unknown, assuming no Hacrocam’s camera unsure (other sites say yes) All other components RoHS Compliant

Solder Can contain lead, tin, silver, copper PCB Fabrication Chemical etching – often uses ferric chloride and other acids ICs Manufacture process contains many hazardous chemicals. LCD Display Known to use sulfur hexafluoride in manufacturing Anti-Heat Spray As a spray paint, contributes to VOC (>>>>5%)

LCD Screen Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit Power Consumption Will be drawing a lot of power while on. Heating Coils & Fan:~10.8W Other parts:> 45 mW

Unit will need to be recycled Sites like greenergadgets.org can help people find electronics recycling spots. Electronic units will be hard to separate from the packaging

Manufacturing Minimize PCB size Normal Use Provide operating instructions to ensure a suitable environment is used for roasting Disposal/Recycling Provide proper disposal instructions.
