At first, we planned to make a bottle that you can cool or heat. We later calculated that we will not be able to produce enough voltage, so we made it simpler. Covering material traps in the coolness and the heatsink on the bottom disperses the heat. The base has a fan that can cool you off and the bright white leds can light a room if necessary. This project is cheap and doesn’t take up a lot of space. It is something that every adventurer should have.
After making this project, I learned how to use the table saw, Autodesk Inventor, and 3D printer. I had to model and print out 4 prototypes of fans in order to make the best one possible. I had to learn how to solder to put our circuit together. I needed to learn how to hook up batteries in series in order to increase their voltage because we needed 6 volts for the motor and leds. I needed to be able to wire 2 pairs of leds in series and then in parallel with each other. This was a good opportunity to acquire knowledge about various things in the areas of the 4 STEM principles. For science, we built circuit with the motor, batteries, and leds. For technology, we used 3D modeling and a 3D printer to make the fan. For engineering, we put the base together and wrapped the bottle in material. For math, we did calculations to find the appropriate size of the fan and the base. We also calculated the necessary voltage to make the project work.
