Kids MP3 Player - Tonuino in More Languages

Kids love music, however they is a range of time (years) in which they are not capable of using a MP3 player as such, so there is some solutions for this problem.

Kids use singular pieces to select the music they want, by placing this pieces on top of a battery-driven speaker. RFID enable this nice functionality.

Some commercial (like this one https://tonies.de/toniebox/) are very good, but closed source and offer not everything you may need.

In my personal case, I found the open-source project "tonuino" discussed in this forum (German forum http://discourse.voss.earth) to be an almost perfect match to my needs. My kids grow up bilingual and the toniebox provides basically products in German so am missing the whole Spanish side.

So I translated the "parents menu" to Spanish and I also added some functionality that I thought would be useful. Like a LiFePo based cell to provide more safety, and a printed circuit board instead of jumper cables to connect the different sub-boards.

If there is interest, I can publish the easy-eda design of the board so that you can order your PCBs at any maker. I paid around 20USD for 40 pieces and I plan to resell many with no earnings in sight. Just what I paid for them. So if you do not want to go through the process.

The video explains everything (please excuse the low quality, the kids and my job take most of my time) under the video description there are links to the components used.

Here two more videos, this time with audio in english

Hopefully you find it useful, the German forum has plenty of very nice ideas about this. Look at this housings:
