Thermometer/hygrometer with probe (Acu-Rite preferred)
Good Thermostat (Helix or Herpstat preferred)




Construction:

1. Create the window -
Cut out a square in the front center of the cooler measuring 9"x7". On the inside of the cooler cut a 1/2" wide by 1/2" deep frame
around the already cut square. Place the Lexan Polycarbonate
window into the frame on the inside of the cooler. Use the silicon
to seal the window in place, applying it on both sides of the window. I used a Q-Tip to smooth out the silicon bead, creating an airtight seal.





2. Create the light -
I used 2 different colored wires for clarity when creating the circuit. Cut a piece of RED wire 3". Cut 2 pieces of BLACK wire, one 3" and the other 2". Strip both sides of each wire. Solder one end of the 2" BLACK wire to the + side of the battery holder and the other end to one of the metal tabs on the push button. Solder one end of the 3" BLACK wire to the remaining metal tab on the push button, and the other end to the smaller leg of the LED light. Lastly, solder one end of the 3" RED wire to the larger leg of the LED light, and the other leg to the - side of the battery holder. Wrap all connections with electrical tape so none of them come in contact with each other, ruining the circuit.



Poke a hole through the top center of the cooler lid. Run the LED light through, and leave the battery and switch on the top of the lid. Fill the hole with Great Stuff to seal it off. Use the a large cap to enclose the battery and wiring
(Optional) Poke a hole in the gatorade lid and push the light
through. Glue the gatorade lid to the bottom of the cooler lid.


3. Assemble the insides -
Cut a small slit for the flexwatt cord on the top side of the cooler.
Tape the flexwatt down on one side, across the bottom, and up the other side. Place the bottles filled with water on top of the flexwatt. Cut a piece of egg crate light pannel to fit inside the cooler, and place that on top of the bottles of water. This is where your prepared egg box will be.









You are finished! Good job.


**Note: You can use this to set up a plastic coleman type cooler as well. Just change the measurements to suit your needs, and maybe add a small fan for even heat distribution.**
