I only speak French, English and Spanish, hence the post in the International category.
I have a two-years old kid, and I discovered RFID-based jukebox at a friend’s home. They seem excellent for toddlers, but I am really unsatisfied by their proprietary and closed conception. That lead me to consider building a TonUINO box.
I am almost a complete beginner in electronics (I did some soldering at school, but that was decades ago), but I am not afraid because I am really used to do things myself, like coding software, repairing bikes and washing machines, etc. Plus I have colleagues that would be able to help me.
I have read a bit of the available FAQs, but auto-translaction from German is not always accurate. For now, my plan is:
buying a TonUINO set from AZ-Delivery, plus a speaker;
adding a speaker, a breadboard, wires, buttons and 1 kΩ resistor (I already have SD cards);
assembling all this to test it on the bench;
determining the kind of box where all of this would fit.
I am unsure of what I will choose for a power source. Using an USB powerbank seems a bit challenging, as I would need to integrate some way to switch the Arduino on, and there seem to be challenges related to power saving which I did not really understand. Using 6 rechargeable NiMH AA batteries seems easier, with a power toggle of some kind.
I also have not decided the kind of box I will use, because I need to see the components to get a proper idea of their dimensions. I think I will keep the breadboard for connections, does that sound reasonable?
And finally, I think I read something about French recordings for the TonUINO menus, do you know if such a translation actually exists?
configure the SD-card (max. capacity 32 GB) with directories “advert”, “mp3” and one more directory “01” which will contain your mp3-files. Directories “advert” and “mp3” must be loaded with full content of mp3-files as These files are the voice Messages the TonUINO needs to communicate with the User.
keep the Arduino connected with your PC and Open a terminal Windows to See what ist going in with your TonUINO (the Software will send Status and Error Messages to the terminal Window)
If everything ist connected and working, you should Heart a “beep” signalling the booting hast completed.
The second step then will be to implement a Power supply other than your PC:
Although some Users report problems with USB Power banks, I would recommend to use one of these as they have the charger already integrated. How to do this:
Cut a USB cable with an USB-A connector. Find black and Red wire, where the black one normally ist GND (Minus) and the Red one ist PLUS (Power or Vcc). Plug the cut cable into your PC and confirm polarity with a Multimeter.
add a latching Switch to the Red wire and connect Switch Output to 5 V Pin (Not Vin Pin) of the Arduino. Connect the black wire to GND Pin of the Arduino.
Disconnect the TonUino from your PC and Plug in the USB-A connector of the newly prepared cable into your Power Bank.
Putting the Switch to ON should now wakke Up the Power Bank and the TonUINO starts booting.
This of course ist a very simple Power supply but ist hast the opportunity to simply extend it for use of auto shut down. Details how to do this may wait until your TonUINO ist working to satisfaction.
Hint: for translations I found very well acceptable results using deepl.com.
