The [logger] is my year project. It helps young people to understand physical experiments a more easily way, but also with exact measurements. These experiments for example, measuring the velocity and the acceleration of a rolling ball on a gradient, or the same with a horizontally accelerated object. But you also can measure the friction on of an accelerated object on various surfaces. The physical elements of the project mostly been printed with 3D printer, but I always payed attention to use a universal materials. This project is completely open source, anyone can access and download the individual models and can print out them, build them. It works with a Nodemcu, and was programmed in Arduino.

Many things you have to 3d print, but you can find a printing manual, that could help you!
