    Hi all,
    Such devices like Xperia U,P.... iPhones,
    and some other devices which have no
    external storage but USB OTG supported,
    can use SD card or pen drive with OTG.
    There are many kind of OTG cables, but it
    is very hard to carry an OTG cable & a card
    reader all the time, so i am thinking of an
    OTG with card reader in a very small (as
    small as it can be) form which can be carried
    all the time.
    the card reader will b stored(may be fixed)
    with the back cover(as shown in the pictures)
    .
    i am usuing very small card reader slot, thin
    wire(like insulated copper coil wire), a tiny
    siwtch(on/off).

    As we know, in OTG pin 4 and 5 are
    shorted so i am usuing a tiny switch, when i
    switch on, the pin 4 & 5 are shorted & the
    cable will work as OTG, & when i switch off
    it will turn as a normal USB cable, so there
    will be no Battery Drain.
    i am trying to configure it ,but having
    problem when soldering the wires with the
    micro usb male port.
    The connections are so tiny, so it is very
    hard to make it alone, i tested it in a bit
    large form & it workes, but in small size as
    shown in figure it becomes very hard to make
    it ,,,,,,,
    i am requesting you all to try it & make it
    by yourself,
    if we can make it personally i think one day
    such cables will b available in market in very
    stable form for all usurs.

    All it takes is someone about 16 years old or younger with steady hand and good eyes, I soldered a lot smaller components when I was (much) younger.
