In order to have more informations on the progress of the original echOpen project, we decided to visit them in Paris.
We first saw their prototype, guided by one of their engineer. It helped us a lot by knowing the difficulties the encountered and which equipment the used.
Then we moved in one of their meeting room and we worked on the project with Mr Debeir. We made the first researches on the equipment needed, particularly concerning the probe.
Finally, we had the privilege to see a demonstration of their prototype. It was pretty impressive and motivated us for our project.
