Splicing in a second Headphone.

Okay so, for whatever reason the headphone hole thing on my MP3 player stopped working, this is the third one I've had this happen to so I don't feel like buying another. To fix it, I was thinking about opening it and soldering in a new one that I could cut off a dual headset adapter ($3.00) then having it hang out of the mp3 player via a hole cut in the casing.

Do you think it would work?

Don't buy Sandisk Sansa's.

Yup, that should work just fine. Might look a little rough but shuold work. Just make sure you do the connections properly, fine guage wires like that are a bit of a pain to work with.

if theres space inside the housing, tie a knot in the wire before it exits the case. that way tugging on the wire will put tension on the knot and the case rather then your soldered connections.

I didn't think of that! I was just going to super glue it to the housing and have the hole be slightly smaller than the cord.

Thanks!

Not possible on this Sansa. Theres no place to solder it too and I can't seem to get the headphone port off from the chip thing. (Its not really a chip, just a mass of digital odds and ends, including chips.)

I got mad at it, jambed a screw driver backwards through the port, and threw it against a wall.

Then I put it all back together and the other ear works. I'm in shock.

If all else failes, get a BFH

Lol, glad it works for you now.

it sounds like the headphone jack is soldered directly to the breadboard...it can be a bitch to remove a component like this unless you have 3 different soldering irons and about 9 hands. i would take my DVOM and back-probe the phone jack and see where it connects on the pc board, then solder my leads onto there....effectivly bypassing the jack altogether. of coarse you'll have to drill a new hole in the case for your wires to exit.

i did a similar project not too long ago and took a few pics which might help illistrate what i mean:

the big silver box on the far end is a set of USB plugs. i just wanted the 5v output from this thing, but couldnt remove those plugs due to them being soldered in a million different points:

so after flipping it over and identifying which contacts inside the plugs went where, i soldered in my 5v+ and 5v- leads (wires near the top of the pic):

the wires near the bottom are my 12v input leads.
