Our new goal is to create a small lantern that switches on and off and uses 2 or 3 AA batteries. The main challenges for this project is creating a switch and battery holder. Our objective is to make it as small as possible. With a partner we must decide on what color light to use, the number of batteries, and materials. We must keep in mind that light intensity depends on the voltage and different colored light need different voltages. A red LED uses about 2V. A green, yellow, blue and white light needs a voltage of about 3.6 to 4. Resistors also depend on the voltage.
There are many ways in approaching this project. Do you want to be able to dim the light. make it stand on its own, have an irregular shape, etc. My partner Cailey and I have decided to make a lantern with a red light since red light is better for your eyes in dark places and use 2 AA batteries. Our idea for the design is a combination of my first box with hinges and Kelsey's dovetail corners.

We want the box the look similar to a shoe box. The bottom will be the battery holder and the top will have the light. We are still not sure how to incorporate a switch into the design. An idea for the switch is pushing down on the top half for the light to turn on. We will work on the battery holder first and then worry about the rest of the parts.
