Tape input

1

I have an old CD / Radio / Tape player at home I like keeping about because
its pretty compact and works.

Though it is the 21st century, so I’d like to rip out the tape deck and
replace it with a phone charger / audio dock for my Nexus 4.

Charging is easy enough, and making a 3d printed part to sit in the tape
deck hole and dock the phone into should be pretty easy, but i’m not sure
what the best way to hook into the tape deck pickups and use it as an aux
input is.

I remember there used to be ‘cassettes’ you could put in that had a 3.5mm
jack, but these sounded pretty wank, so i’d rather hack a 3,5mm jack in
directly if possible.

Any Ideas?

There are plans online to do exactly what you are asking for, I think it
was on hack-a-day about 5years ago.

Thanks,

You’ll probably find that there is a circuit that does the tape-head to
audio conversion, that then goes off to the switching circuits and
amplifier as L, R and ground. It might be all one board if your unlucky,
but you can always cut tracks and solder wires :stuck_out_tongue:

My mate added Aux-In to his car CD player by just finding the amp on the PCB and soldering directly to that. The only thing was that the amp didn’t switch on unless there was a CD playing, so he just burned a CD with 70mins of silence!Date: Tue, 29 Oct 2013 22:07:30 +0000

They were, I had one and the audio quality was awful.
