Wouldn't it be nice to have a cold beverage right next to you? In this project I will show you how to achieve this luxury by building a homemade cooler which decreases the temperature of your beverages down to 8 degree Celsius. Let's get started!

Step 1: Watch the Videos!

The two videos give you all the information you need to build something similar. For further reference see the following steps.

Step 2: Buy Your Parts!

Step 3: Build the Case!

Here you can find the measurement for my three layer case design. Feel free to build your own like this or get creative and change it in one way or another.

Step 4: Wire Up the Electronics!

Here you can download my Arduino Code and the schematic that I created during this project. If you build everything like it is described then there shouldn't occur any problem.
