I am planning to make this project (looks super fun for kids) but your link to the PCB/
Schematic seems to be problematic: https://blog.hirnschall.net/downloads/download.php?file=useless-box-schematic.zip
Can you help?
Useless box (Arduino controlled)
A useless box that uses a single moving arm to press multiple switches. (Originally designed for a friend of mine.)

the wooden box I used required some sanding otherwise great idea
awesome gift
A bit tricky to assemble...
but the finished box is quite nice :)
I really don’t like gluing parts together either.
However, it is one of the easiest ways to deal with crooked box walls and avoid screws that are visible from the outside.
really cool
