Tonuino Case Tulexa

thingiverse

This is a case for the Tonuino music box, where you can find more information about the project on the website https://www.voss.earth/tonuino/. The description of this German project is, as expected, in the German language. Required components include: - Arduino Nano (Clone), DFPlayer Mini and RFID Module: https://www.az-delivery.de/products/tonuino-set - 3" speaker: https://www.adafruit.com/product/1314 - 3x7cm PCB: https://www.amazon.de/gp/product/B0728HZHTR/ - 2x toggle switches: https://www.reichelt.de/wippenschalter-rund-2x-ein-aus-ws-r13-244-a-p105450.html - 1x slide switch: https://www.reichelt.de/schiebeschalter-miniatur-loetanschluss-2x-um-t-219-p19977.html - 3x arcade buttons: https://www.amazon.de/Schalter-Druckknöpfe-Perfekte-Ersetzen-Kampfspiele/dp/B0819ZZRKC - 1x USB breakout board: https://www.ebay.de/itm/USB-Adapter-Platine-USB-2-Standard-A-zu-RM-2-54-Breakout-Board/182941985853 - 1x battery holder for 4x AA batteries: https://www.ebay.de/itm/112522035628 - 3x 5mm LEDs for PowerOn and Night Light PCB: I built the PCB according to the schematic on https://www.voss.earth/tonuino/. The current version (v2) has a 5-pin connector that allows it to be powered with 5V directly or through Vin. I removed unnecessary pins from the header using a pair of pliers, which makes it possible to connect all pins on the back side (see PCB layout). Of course, the PCB can be used in other enclosures. Power Supply: !!!ATTENTION!!! I power the box directly via the 5V input. For battery supply, I use batteries with a lower voltage (around 1.2-1.3V) compared to standard batteries. This allows me to switch between USB and battery without additional electronics. Printing: All parts can be printed without support material. All holes are closed. After printing, they need to be drilled. The large central part already has integrated support material. The holes for the buttons are also closed, so you can save on support material. Depending on which switches or buttons you use, you may need to modify the holes with a file. Assembly: For assembly, the following screws are required: - 4x M3x6 cylinder heads for speaker - 4x M3x35 cylinder heads for connection between speaker holder and enclosure - 4x M3x40 cylinder heads for connection between enclosure and battery box - 2x M2.5x10 countersink screws for battery holder - 4x M3x20 countersink screws for battery cover I used self-locking nuts for all screws. Only the M2.5 screws have been secured with locktite.
