Stand alone CDROM audio driver

Most of the CDROMS available have an Audio-Out Output to either plug in the headphones or connect it to an amplifier. This circuit enables one to use the CDROM as a stand alone Audio CD player without the computer. This circuit is nothing but a power supply which supplies +5v, +12V and Ground to the CDROM drive and hence can be used without the computer. You should buy a D-type power connecter to connect this circuit's outputs to the CDROM. The details of the D connector are shown along with the circuit diagram. Note that the D-connector goes into the CDROM in only one way and hence prevents any damage due to wrong connection. Ensure that the 12V(yellow) wire is connected to the right of the D-connector(as seen from behind, i.e the connector holes away from you with the curved portion of the connector upwards). As soon as an Audio CD is inserted, the CD begins to play. To move to the next track, press the Skip-Track button on the CDROM front Panel.

The circuit described facilitates the operation of a CD-ROM drive as a standalone audio player by providing the necessary power supply. The power supply circuit is designed to output +5V and +12V, along with a ground connection, which are standard voltage requirements for most CD-ROM drives. The use of a D-type power connector is crucial for establishing a secure and reliable connection between the power supply circuit and the CD-ROM drive.

The D-connector is designed to fit into the CD-ROM in a single orientation, which serves as a safeguard against incorrect connections that could lead to potential damage. This feature enhances the user experience by simplifying the setup process and ensuring the device operates safely.

When connecting the D-connector, it is essential to observe the color coding of the wires: the yellow wire, which carries the +12V supply, must be positioned correctly to the right side of the connector when viewed from the rear, with the connector's curved portion oriented upwards. This attention to detail is critical in maintaining the integrity of the circuit and ensuring proper functionality.

Upon inserting an audio CD into the drive, the playback begins automatically, allowing users to enjoy their music without needing to interface with a computer. The front panel of the CD-ROM drive typically includes a Skip-Track button, which provides a simple means for users to navigate through the audio tracks. This design emphasizes user convenience and accessibility, making it an effective solution for those wishing to utilize their CD-ROM drives for audio playback independently.Most of the CDROMS available have an Audio-Out Output to either plug in the headphones or connect it to an amplifier.
