In September 2016 we began to build our first prototype. This prototype, built out of waste we found at home and which was manually operated (without electronics), was only used to test the functionality of our idea. It showed us problems that were easily resolved and gave us the affirmation to continue with our next phase. We started a new prototype in our optional lesson, called "projects with Arduinos", that should outperform our first one. With the help of our teacher Philippe Kirsch, we could realize a new, more performant and digitally controlled machine.
