Creating a Custom Talking Card with Sound Recording Feature: DIY Guide & Sources for Components

Hello,

I am asking in advance for gentle treatment and answers written in a simple, understandable language for a woman and a layman. :-)

I don't know if I'm asking this question in the right place and I don't know if I'm repeating myself, but most of the topics on this forum are black magic to me. But to the point.
I would like to do it, because unfortunately you can't buy a playing card anywhere, or rather a talking card, because I would like the sound from my computer to be recorded there.
One company offered me to perform such a service for PLN 100, and in my opinion it is many times higher than the actual cost of performance, so I would like to do everything myself, and here I am asking for help.
Where can I buy such an element as in playing cards and how to record my sound on it? Maybe there are companies that will send me this part with the sound already uploaded? It would also be nice if the sound did not turn on after opening the card, but only after pressing the button.

I am asking for your understanding and help.
Thank you in advance and best regards.

1. you can follow the layout from this site and prepare a WAV file: http://elm-chan.org/works/sd8p/report.html
2. you can buy a ready-made MP3 player module and remove unnecessary jack and USB sockets, and even a card slot (solder the card permanently): http://dx.com/p/mp3-player-module-w-micro -sd-card-slot-mini-usb-3-5mm-jack-156001#.Ut45AxCtbDc

In my opinion, the price for making and programming a single circuit is very reasonable, ordering several thousand such circuits would certainly be much cheaper. You will not do it yourself (bet?) Without knowledge in the subject and the appropriate accessories, today for PLN 1 it is "buying" a phone ... no offense. Regards.

speedy9 Thanks - I'll read it and see if I can get through it. :-)

cirrostrato If you don't want to help, then don't comment unnecessarily and don't offend, please.

I'm not insulting (if you took it that way..) I'm just specifying the reality, my friend speedy9 showed links to topics where the layout will be the size of a Marlboro pack, and I don't think that's what you mean. Once again, I assure you that a system that works exactly according to your needs and costs PLN 100 is a bargain. Regards.

I just found a ready-made one, on which I may not drop the sound from the computer, but I can just record it and such a module costs PLN 18.50 and that's enough for me. So it can be done!

Give me the link.

Please.

It is not checked, but this module is based on volatile memory, i.e. when the battery is discharged, we lose what has been recorded.

On Allegro "ISD1820 module - message player - developer" or link - the record remains after a power failure

oh I hadn't thought of that - thank you! Only this module seems to me too "high" to hide it in the playing card.

Probably not quite on non-volatile memory, though. From the description of a similar module on Aliexpress.com:

Quote:

if no longer used after the last recording will be saved for about a year.

However, I think the batteries just last about a year After replacing them it works again. It's just that replacing them in a card is rather problematic without destroying it.

If you like soldering, you can try with the ISD1730 system, the price is about PLN 18 in tme. The circuit is simple, it does not require external components (except one resistor to set the sampling rate) or an additional mcu to control it. It has an analog audio source for recording, an analog speaker and pins to which you simply connect play, stop, etc. It has non-volatile memory.

Why do you conclude that?

1. I have similar modules
2. Closing the page is the Play button, and it is not used to cut off the voltage, because the Rec button would not work
3. On the given page, only this one is not listed as "non-volatile"

ISD1820 module - message player - caller
It is described as "non-volatile"

Italian18 Could you tell me which company can make such a card? I want to be able to record a track longer than 10 or 20 seconds. I will be grateful
