Circuit / PCB / Device To Play USB Flash Drive MP3 Audio On Power
$30-5000 USD
货到付款
I need a device/circuit similar to a buzzer or chime. When power (12 volt) is applied, I need a certain mp3 ([url removed, login to view] audio) file on a removable flash usb drive to be played. This way, a user can customize the message by taking the usb flash drive to a pc, and putting a different mp3 file on the drive with the same name. It can play first on list if it is easier to build/find. Circuit either needs a speaker or a headphone/stereo jack where sound will come out. Nice to have (but not necessary) would be a switch to configure for repeat play, one time play. Play should always stop when power is removed.
Device should not be overly large in size.
Please open discussion if you know of such a thing exists and you know where to find it or modify it. If it does not exist, I need a bid/discuss to build it. Building it would involve circuit and components. [url removed, login to view] or similar would be ideal. This can be discussed further.
