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: AZ-Nano V3 board Mini MP3 Player  RFID Kit RC522 A passive bookshelf loudspeaker (unfortunately usually only available in a double pack) / any loudspeaker Micro SD card (maximum 32 GB) some odds and ends (cable, 1K resistor, buttons) https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-04-21 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-07-06 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-09-20 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-10-31 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-11-01 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-11-26 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-11-27 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2021-12-27 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-02-17 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-02-18 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-03-21 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-05-09 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-07-27 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2022-09-26 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2023-04-04 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2023-07-21 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2023-09-22 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2023-09-23 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2023-12-05 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2025-01-08 https://elecena.pl/product/17814710/tonuino-set-mp3-player-az-nano-v3-board-rfid-kit-and-10-x-13-56-mhz-rfid-cards 2026-05-02
