montajul prezentat este un modul care poate inregistra/reda un mesaj vocal cu durata de maxim 20 secunde
aplicatii:

-pentru alarme (va rog pastrati distanta - la alarmele auto)
-diverse in auto sau alte aplicatii (alarma declansata) etc
sunt sigur ca gasiti mai multe intrebuintari

Description

The ISD1000A is a Direct Analog Storage device which allows you to store 20 seconds
worth of voice data on an IC chip which can be play backed anytime. The data stored
will stay in memory even if the power is removed. To use the circuit below simple apply
power to the circuit, press the record button and hold. Speak clearly into the microphone.
You have up to 20 seconds of voice message that you can store. If you talk beyond that
time the chip will only store the first 20 seconds. After recording, release the record
button. To playback the message, press the playback message and the message you recorded
will play back. The microphone is an electret mic and the speaker is a 8 ohm speaker.
If you use a 16 ohm speaker then the 10 ohm resistor marked optional, can be eliminated.
This circuit can be the basis of many other larger projects. For example it could be
part of an alarm circuit which plays back a voice warning when the alarm circuit is
triggered.

Este interesant dar de unde-l iau ?. In Romania cel putin nu-l vinde nimeni.
