TonUINO Set (Mp3 Player, AZ-Nano V3 board, RFID kit and 10 x 13.56 MHz RFID cards)

TonUINO, THE DIY jukebox (not only) for children You can find the latest updates on the Tonuino here: www.tonuino.de

I have been looking for a cheap and, above all, convenient solution for a children's music box for a long time. There are, of course, commercial solutions and a few DIY projects online. However, the commercial solutions are too inflexible for my taste and most DIY solutions are based on a Raspberry Pi and are usually quite clunky. In addition, none of these solutions have yet been able to offer a clever solution for programming the RFID cards. The mini MP3 player already has a small mono amplifier. You can use it to drive a passive loudspeaker directly and I think it sounds really good! If that's not enough, the module also outputs a stereo signal. If you add a small amplifier, you can get even more sound out of it and, above all, use two speakers as a stereo pair.

The TonUINO takes up so little space that you can install it directly in a passive shelf speaker, for example. Apart from that, there are no limits to your creativity. I can't wait to see what ideas you come up with. Another advantage of the Nano compared to a Raspberry Pi is that the AZ-Nano V3 board is ready to start in 1-2 seconds and does not have to be shut down to switch it off. It requires significantly less power and can therefore be operated via a battery pack.  Required hardware:
