Smart-Fridge

Hello everyone, we had to make a project for our first year in MCT at HoWest. I chose to build a Smart-Fridge and give it my own little touch! I tried to make it as 'cheap' as possible so everyone will be able to make it! In this instructable i will try to lead you through the whole project so you can make this Smart-Fridge all by yourselve! Enjoy!

Here you can see how my electronic scheme is looking!

Step 1: draw and measure

1. We will need 4 pieces in total! 1 to put the drinks on, 1 to stop the drinks from falling when you open the fridge! And 2 to give the plate a downangle so the drinks come to you automatically!
2. Measure the 4 pieces so they fit perfectly in your fridge! You will need a measurement tape for this job!
3. Draw the lines so you know exactly where you need to cut with your saw!

Step 2: Saw

1. Now that you drew everything it's time to put some 'dirty' work in! Take a saw and start cutting of all the pieces you don't need! I use a vice for this so that my shelf will be steady at all times when i try to saw it.

Step 3: Glue it!

1. Put everything together with a glue gun! Try to be as precise as possible so you're shelves are in the right place and you don't need to start all over again!

If you want to know how my database looks!

You always can write your own code! But if you want to make it easy for yourselve i will let my github repo in here so you just can use my code as an example!
