Hi everyone,
I don't know if here is the good place for this question. Please, let me know if not.
I need to record new messages in a voice recorder module (photos below) taken from a toy. This module is a small board with an unknown chip, a speaker and a switch activated by motion, etc..
It has the following characteristics:
- Multimessages: it came with 44 posts totaling over 100 seconds of records;
- Pseudo-random access of messages: There are actually only 10 messages recorded 44 times in a random sequence. When the "play" switch is turned on (by shaking the toy) it gives the impression that the messages are accessed randomly.
- There is no microphone or indication to where to connect one.
My questions:
- Can anyone help me with more information about this circuit and, if possible, tell me how to modify/complete it to enable record and play modes?
- The contacts P22 and P23 would be for a microphone?
- One can read on the board: 10191, 10193... That would be the number of the chip?
Thanks in advance for any help.
