Tonuino, the DIY music box (not only) for children
The latest updates to Tonuino can be found here: www.tonuino.de
I was looking for a cheap and, above all, comfortable solution for a children's music box for a long time. Of course there are the commercial solutions and some DIY projects online. However, the commercial solutions are too flexible for my taste and most DIY solutions are based on a Raspberry Pi and are usually quite chunky. In addition, none of these solutions have been able to offer a clever solution for programming the RFID cards.
The DFPlayer Mini already has a small mono amplifier. So you can drive a passive loudspeaker directly and I think it even sounds really good! If that's not enough: the module also spends a stereo signal. If you add a small amplifier, you can get even more sound out and use two boxes as a stereo couple.
The Tonuino takes so little space, for example you can install it directly into a passive shelf speaker. Otherwise there are no limits to your creativity. I'm looking forward to what kind of ideas you come. Another advantage of the AZ-Nano V3-Board compared to a Raspberry Pi is that the AZ-Nano V3-Board is ready to go in 1-2 seconds and does not have to be shut down to switch it off. It needs significantly less electricity and can therefore be carried out super through a battery pack.
- AZ-Nano V3-Board (if you work without my circuit board, a UN or AZ-MEGA2560-Board is also possible)
- Dfplayer mini
- Rfid kit rc522
- A passive shelf speaker (usually only in a double pack) / any loudspeaker
- Micro SD card (maximum 32 GB)
- some small stuff (cable, 1k resistor, buttons)
- (optional) a Tonuino board
