Note: Read all directions listed here before proceeding to the actual build. If this option is used there is no need to flatten the tab in step #3 or use any of the insulation material. Materials needed are Super Glue and Baking Soda. Download the instructions (1.66mb).
1. Cut a strip of metal (provided in the kit) to one inch in length and 1/2 inch in height. The strip should fit tight inside the battery holder. Keep the top edge of the metal strip below the lip of the battery holder as shown below. This will prevent interference with the sliding lid.
2. When super glue and baking soda are mixed together it turns into a type of rock hard plastic that can be sanded or drilled. In this case it will be used to lock the metal strip into place. If desired, use a small clamp in the center of the metal strip and clamp it to the battery holder.
Apply super glue to the right side and then add baking soda to it. Don't worry about excess. Now apply super glue to the left side and add baking soda to it. Lastly, apply super glue to the bottom and add baking soda to it. It will harden almost instantly but allow a few minutes to really set up.
3. Rinse with water and dry. Now there should be a layer of "plastic" around the edges of the metal strip. This will keep it locked into place.
4. Now solder one end of the thermistor to the back of the plate and route the wire through the opening.
5. Not required but the mixture of super glue and baking soda can be painted.
