Recording Disks Are Nearly Full Circuit Diagram

Recording Disks Are Nearly Full Circuit Diagram Planning to buy a small voice recorder to record voices or sounds in an environment and store them in its memory?Think again! You can easily build your own voice recorder by following a few simple steps. This project focuses on building an Arduino Based Voice Recorder, which can also be abused as a spy bug.Our spy bug uses a small microphone to record the voice and it stores the recorded voice Fig. 1: Circuit of voice recorder and playback system Circuit and working. Fig. 1 shows the circuit of voice recorder and playback system. The circuit is built around voice recording and playback IC APR9301-V2 (IC1), voltage regulator 7806 (IC2), npn transistor BC547 (T1), 8-ohm, 0.5W speaker (LS1), electret microphone (MIC1) and a few other The circuit of voice recording and playback is build around chip APR9600 (IC 1). The recordable sound is changed to voice signal using microphone and given to IC 1 through differential amplifier. This signal is further amplifier by inbuilt pre-amplifier and by connecting pin 21 to pin 20 via an external DC locking capacitor C 1 .

As a result, voice or audio data are saved straight to the memory space in their organic form with virtually no compressions as done in digital technique, offering top quality, solid-state audio duplication. The circuit offers excellent audio recording using straightforward procedures. I show You how to build audio recorder with this simple DIY circuit and easy-to-follow tutorial.Learn how to make an electronic circuit that simple way and g The proposed circuit of a programmable single chip voice recorder/player utilizes the IC APR9600 as the main processor of the circuit. It's a 28 pin IC which can be very easily and quickly configured for getting the required results by adding a handful of common passive electronic components.

Voice/Audio Recorder Playback Circuits Circuit Diagram

The circuit contains a microphone amplifier and a speaker amplifier. We can say it's a digital voice recorder. S1 switch is for recording / play-back ( recording in ON position ). When S2 is OFF the IC goes in power down mode. S3 starts the recording or play-back and must be a push-button. For more voice recorder circuits check the list bellow. Voice Recorder with 10 seconds Recording Time: This reference design implements a solid state voice recorder using MSP430F149 microcontroller to convert the analog voice pattern to digital with its integrated 12-bit analog-to-digital converter. The voice data is stored real-time in the MCU Flash memory and played back.
