When I first got this circuit, I, was a bit crappy. I pressed the subject ... Then again formally organized. In this circuit, as a brother stepped on it and sold it on the market or even a little vulgar.
Now an electronic worker has developed a little more, the new version is printed, sell. I share, I said that I have the old. nor is there a new one.
When New phakic what you say, the only difference between a sound output IC was added, that's all. His own voice in the audio output of this circuit is not low. suffices. Until you hear is the sound of a mobile radio.We wish you can add the output of course.
I have attached drawing file, proteus ares. Status of the circuit that was impossible, at least a thousand. Do not short circuit the ends of a single HP need to be careful.
NOTES ON THE CIRCUIT:

60 seconds while recording the audio output of this circuit is available on its own. Desired output power for professional use aux out can output to an amplifier.
Condanser in circuit with the microphone you can make an audio recording of a very sensitive, such as the position of the circuit jumper, "MIC" to "Aux" aux in the entrance of a taking can also register. This entry dvd, vcd, phone radio, mp4, you can save by implementing the direct sound devices such as PC. Use 4-16 ohm 0.5W as a speaker to speaker.
Voltajımız feed at least 5 volts. Feed with 12 volts. To regulate the voltage to 5 volts to operate our circuit does not affect the rise and violet. When we give energy to our circuit, our circuit is ready to work we will notify burning power ledimiz.
HOW TO REGISTER TO DO?

To record in rec / play switch, press the illuminated mimic diagram turns on and you should see the record.Record LED is lit, this to us, the record shows that at the time of the circuit. Ledine busy this time to look at this. Because all the movements of busy entegremizin LED lamp has been translated to us. For example, while the record key not pressed, it means that there is space for recording Ledin be illuminated. Means the area to be filled with the light goes out when you register.
