    Since i can talk about ANYTHING here..i want to ask for help, because there are people here who are really good in electronics and i like to repair and have fun with that stuff :D

    But i got problem... i soldered some wires to repair my headphones, i want to use them for my 3DSXL and PSP, but sound output is..not normal and certanly not stereo :/ its more like right side is louder than left and cant hear all tones..its nice, but not normal as in compare to other headphones i have.

    Ok, here it is.
    First, let me tell you what i did.
    There where 2 jacks on the cable:
    1. pink (microphone)
    2 green (speakers)
    [​IMG]

    and in the middle of the cable there where that thing that regulates volume and mic. on/off
    this:
    [​IMG]

    And there was microphone it self as you can see on the first picture.

    What i did is i cut pink (mic.) cable, mic. it self and that volume up/dowh thing that was in the middle of the cable... now i have 2 speakers, one clean cable with green jack.



    This is the wiring and soldering i did (sorry for primitive paint drawing :P ) ..what is wrong here??

    That does sound like a dodgy connection.

    Were the wires kind of metal looking (maybe a nice bright colour you do not normally see in metals) but not otherwise covered in any plastic?

    If so they were enamel covered (it is pretty much standard in headphone world) and that stuff really does not solder well.

    You have two options here
    1) The boring way
    Get a molten blob of solder on your iron and hold the end of the wire in there for several seconds and it will tend to strip the enamel. Do not use the solder blob to now solder with.

    2) Fire
    Take a lighter, a gas cooker or something with a small flame on and shove the end you want to solder in. Watch it spring into flames and then do not hang around before you put it out (you might want something with water in that you can dunk it in). Solder as normal though you might want to tape it up/heatshrink it or something if you are worried about wires touching.

    So you think wires are ok... but connection is not good?

    hm..but it looks soldered :/

    I tried somehow to strip off enamel from vire (by the way, i hate that thing) but i dont know how good contact is :/

    Amazing man! thanks A lot for this tip! :D
    My headphones are now GREAT now!! i soldered everything as i should. it turned out i soldered ground to R speaker and let red wire act as ground..silly me hehe :P

    ..now i know how to remove stupid enamel from the wire (it was a nightmare before your tip i tell you! -.-' )

    Now i play "Hatsune miku - Project DIVA extended" all day! :D (great game by the way and there's even English patch!)

    xD :)


    ...
    And by "Do not use the solder blob to now solder with" you mean blob i used to melt enamel,
    not to use it now for actual soldering because it mixed with enamel?

    Rewiring incorrectly would do that.

    Yeah enamel mixed with solder could have all sorts of effects. I am actually not sure what those might be right now (other than risking it reforming around the connection and increasing the resistance) but I would put reasonable money on it not being good.

    Anyway I know they are not the fanciest headphones but it is always nice to fix things like this. If something like this happens again hopefully you will not have the fun of trying to remove the enamel with sandpaper or something.

    Is there some good website where i can learn soldering and get tips and similar tings? :)

    For soldering I was mostly taught by people that know how to solder and I picked a few other things in other places.

    Still I feel comfortable linking up




    He has some other videos ( http://www.youtube.com/user/EEVblog/search?query=soldering ) on some of the more industrial/expensive things you can do like hot air, reflow ovens, wave soldering and some more general theory but those will cover the basics well enough.

    The rest of his videos ( http://www.eevblog.com/episodes/ , though down at time of posting) do well for electronics. There are loads of other places to learn electronics these days, http://www.allaboutcircuits.com/ , http://ocw.mit.edu/courses/electric...s-and-electronics-spring-2007/video-lectures/ and though it is a vendor site https://learn.sparkfun.com/tutorials is not bad for some more project/specific things.

    General fun things tend to find their way onto sites like http://hackedgadgets.com/ , http://hackaday.com/ and other things like that, I tend not to read them much these days but if you are trying to take in info then it is nice to see where things can end up. There are some interesting things happening in the console world with people taking old consoles and improving things, usually sound and video, on them.
    I will still make time for things like the following though
