The not completely useless box
last updated: 2020-12-29
Introduction
XMas :). So here is the not completely useless box. All the material are recycled or were part of my basic electronics stock. The idea and parts of the code are from this page: https://www.labdomotic.com/2017/10/24/youtube-useless-box-fai-da-te/. To ensure that the box is not completely useless, it has a 3D printed compartment for jewellery (right corner).
Here some of the 16 different actions:
