Case for Tonuino, the Toniebox Replica

I really loved the Tonuino by Mr. Voß: https://www.voss.earth/tonuino/ (German)

It is a mp3 player where the tracks are triggered by a nfc card. The audio files are stored on a micro sd card.

Here is my enclosure for all the components. The goal was to provide screwless places for (almost) all components.

BOM:

• Visaton FR 10 https://www.amazon.de/gp/product/B003A63NLE (any other speaker with 10cm diameter should work)
• Mini RC522 RFID Reader https://www.aliexpress.com/item/33024803665.html
• DFPlayer Mini https://www.aliexpress.com/item/4000464600377.html
• USB Type C Li-Ion charger TP4056 https://www.aliexpress.com/item/32649780468.html
• Arduino Nano https://www.aliexpress.com/wholesale?SearchText=Arduino+Nano
• 26650 Protected Li-Ion Battery
• 5V boost converter
• 3* Arcade Buttons 24mm https://www.aliexpress.com/item/33029433051.html
• 1K Resistor
• Cables
• 4 M5 Screws
• 8 M3 Screws

Switch 12mm* 19mm I hope i did not forgot anything.

Software: https://github.com/xfjx/TonUINO
Fork with the feature that the playback stops if the card is taken away: https://github.com/mcgreg1/TonUINO (i use this)

The charging board gets installed upside down. This way you can see the led indicators through 2 tiny holes in the enclosure.

I used pin connectors but i had some troubles with it due to too high contact resistance. I recommend to solder all connections.

Thanks to Thorsten Voß.
