How to build a music-box for children
The Tonibox is a music player for children. They can simply place figures on the box and depending on the figure, a corresponding audio book is then played. I like this concept and since my child loves audio books, I am going to build such a box.
Note: I never had an original Tonibox in my hands. So I don’t know about it’s exact features and also don’t know how it really works. This article simply describes how I would build such a device.
