+## Idea / Motivation
+seen an [article on Make](http://makezine.com/projects/create-raspberry-pi-smart-beer-fridge/) of a [beer fridge enhanced with a wii balance board and a raspberry pi](https://github.com/InitialState/beerfridge/) and thought this could be a great thing to safeguard our beer and Mate supply. Since tecer already [did a project with a hacked Bathroom scale](2016-05-10-motivationswaage.html), we can profit from his experince.
