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
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.
