TEAM BOAR

1. An ability measure internal temperature of two separate points in the meat and the temperature inside the roaster using RTD sensors.

2. An ability to control the temperature inside the cooker by modifying gas flow using a logic controlled valve.

3. An ability store and load cooking profiles from memory.4. An ability to automatically ignite at the push of a button and

detect whether a flame is present.5. An ability to wirelessly communicate temperature

information to a remote display device.

PSSC’S

Steel (Electricity & other manufactured tools) Drilling Grinding Stamping (for mass production) Welding (for mass production)

PCB / passive components (Potential environmental hazard) Minimal compared to overall size of project

Propane (used in tests)Most wasteful in this stage

Various valves Most have specified (socially acceptable) means of production

ENVIRONMENTAL LIFECYCLE ANALYSIS(MANUFACTURING)

Propane Efficiency vs. cost E & C vs. environmental footprint

Heat Releases CO2 into atmosphere (Unavoidable with any cooker)

Common AA batteries Will need replaced multiple times in cooker’s lifetime

(Leftovers) Bones “Drippings” All other “non-meat”

ENVIRONMENTAL LIFECYCLE ANALYSIS(NORMAL USE)

Cooking tank Entirely steel

PCB’s/ passive components Easily detachable from tank Only 2 small boards (documentation in manual for proper

disposal)Liquid propane tank

Steel Recyclable “at location where liquid propane is sold”

“Leftovers“ Biodegradable “Compost pile” Feed it to the dog

ENVIRONMENTAL LIFECYCLE ANALYSIS(DISPOSAL)

Testing Typically warm weather Not meant to be used in storms (but will resist “liquids”)

Warnings HOT SURFACE!!!! Contents under pressure Pinch points Electrical components

User documentation Provide description of what and how to revert to manual operation Easiest to think “what would be in a grill manual”x5

Added safety Propane tank (Bleeder valve, special fitting) Solenoid (no power = no flow) Thermistor (no heat = no flow “unless in startup sequence”) Software alerts (in conjunction with Thermistor) Gas shocks (pinch points are not erased, but easier to react to)
