Dual terminal block with two-pole and single pole relays

Finished cooler housingDay 4 was entirely focused on wiring all of the switches and controllers together using relays. For the Tuesday deadline, only an initial prototype is required. For the final build the team will purchase two three-pole relays to complete their cooling system. As of now the cooler only runs off one module using battery power. The module turns on only when the on-switch is in position and the temperature controller calls for power. Eventually the cooler will be cooled using two modules when AC/DC power is connected and only one module when solar powered is connected. The system is designed to maintain an internal temperature of < 40 degrees F in an 80 degree F environment.
Stay tuned as the next steps include attaching and wiring the solar panel, connecting the additional module, and cleaning up the wiring and interior housing. All this before the final build is due April 9, 2009.
