I have an interesting project I'd like some advice on; I have a couple of old boombox stereos I would like to convert to an mp3 player/ recorder.
Essentially, what I want to do is install a CODEC board into my the case of my radio and solder the audio line Out and line In ( tape monitor ) lines to the mp3 device.
I want to use a mp3 codec that has both an SD card and a USB host that will allow me to play files on a USB stick, as well as be able to RECORD line out from, say the radio or the CD player and store that record as mp3 on my jump drive.
Is this possible?
The radio I will experiment with is a Jensen SCR-415A, AM/FM stereo cassette recorder. Also I have a Sony AM/FM CD boombox I could try..
For wiring the mp3 player into the stereo I was thinking of using the cassette deck wires because A, that would give a direct line-level IN and OUT to the amplifier.
The tape deck has record/ monitor circuit,
Was thinking of removing the tape deck and mounting my mp3 in this space, wiring it to the appropriate lines on the amp..
1: where can I find a single board mp3 player that does both playback & record, has USB host port, and has analog I/O that can solder directly to an amp/ receiver?
2: is my idea of wiring in place of the cassette recorder a good idea?
Is the output monitor circuit of a cassette recorder line level? or is it amplified/ powered?
3: what would I need to wire power to the mp3 player? Assuming the device operates at 5V, and my radio operates on 6V ( 4 D batteries ), what would I need to regulate voltage to get what I need ( 3.3 or 5 volt ) from the radios power supply?
