Around one week ago, the Engadget blog reported the achievement by Qian Qin, who successfully make the wireless inductive charging mod on Samsung Galaxy S. He also uploaded a YouTube video clip.

To reveal more details of this impressive modification, I construct my copy version and take  illustrating photos for key steps. Basically I divide my modification into two sections: the first section focuses on the remodel of micro usb plugs, the target is to reduce the space requirement of the plug; the second section is the migration of inductive circuits from the Palm Pre back cover.

Step 1.1. Remove all pins from a micro usb plug, the pins are still useful in later step (see Fig. 1). Fig. 2 shows a clear plug without any pin.

Fig. 1

Fig. 2

Step 1.2. Saw of the metal part of clear plug in the middle. To prevent the distortion by saw, the metal part should be fix tightly (see Fig. 3). Fig. 4 shows the two cut-off parts of a plug.

Step 1.3. Make a clear plug following the same routine as step 1.1. . Cut the plastic slots with the same length of the metal part in last step (see Fig. 5).

Step 1.4. Bent one pin to ensure that it can fit into two pin slots. Solder it with thin cable (see Fig. 6). Combine the metal, plastic parts and the pin to a new mini version of micro usb plug.

Step 2.1. Remove the inductive circuits from the Palm Pre back cover (see Fig. 7).

Step 2.2. Solder cables for the inductive circuits (see Fig. 8). Positive to the modified micro usb plug, Negative will be done in next step.

Step 2.3. Cut a small piece of copper sheet. Solder it to the negative cable in the inductive circuits (see Fig. 9).

Fig. 9

Step 2.4. Affix the copper sheet to the Samsung Galaxy S back cover. Add filling to ensure the contact of copper sheet and the metal cover of sd card slot or sim card slot (see Fig. 10).

步骤2.5. Affix the inductive circuits to the Samsung Galaxy S back cover (see Fig. 11).

Step 2.6. Done!!! (see Fig. 12)

After all the 10 steps, my inductive charging works properly with the Touchstone dock.

002. Click on “Free non-commercial” under “Tools & Downloads”

003. Download “Intel® C++ Composer XE 2011 for Linux” and “Intel® Math Kernel Library (Intel® MKL) for Linux”, your email-box will receive letter, which contains the series number for installation.

004. Unpack those two package files, then in each main folder, run:

sudo ./install.sh

005. Choose default setting with series number. Then installed files should be in /opt/intel/

006. Edit the .bashrc file in your user’s home folder, add following codes. Those two path are supposed to be your file location, it make change a little. And “ia32″ is the parameter of platform, you can choose what you want following the instruction in file iccvars.sh and mklvars.sh.

source /opt/intel/compilerpro-12.0.1.107/bin/iccvars.sh ia32
source /opt/intel/mkl/bin/mklvars.sh ia32

|*******************************
|** Part 2. Linking in Program ******
|*******************************
009. Add MKL 10.x header file INCLUDE path in your compiler command line, your makefile or configure file. (default: /opt/intel/mkl/10.x.x.xxx/include)

010. Add MKL 10.x library path in your compiler command line, your makefile or configure file. (default: /opt/intel/mkl/10.x.x.xxx/lib/32)

011. Specify the corresponding libraries in your compiler command line, your makefile or configure file.
With static link, they are as follows:

-Wl,--start-group
/opt/intel/mkl/10.0.xxx/lib/32/libmkl_intel.a
/opt/intel/mkl/10.0.xxx/lib/32/libmkl_intel_thread.a
/opt/intel/mkl/10.0.xxx/lib/32/libmkl_core.a
Wl,--end-group
/opt/intel/mkl/10.0.xxx/lib/32/libiomp5md.so -lpthread -lm

With dynamic link,

-L/opt/intel/mkl/10.0.xxx/lib/32/
-lmkl_intel.so -lmkl_intel_thread.so -lmkl_core.so [-liomp5md]
[-lpthread] [-lm]

the path maybe slightly different due to different installation, just take a look in the install folder.
Note 1: In case of using static linking, the interface layer, threading layer, and computation layer libraries must be enclosed in grouping symbols (<-Wl,--start-group, -Wl,--end-group).
Note 2: Specifying MKL library path in the link command line is required. For example, -L/opt/intel/mkl/10.x.xxx/lib/32, so that the linker can search for real archive libraries.
Note 3: The order of listing libraries in the link line is essential, except for the libraries enclosed in the grouping symbols.

012. Set MKL library path to LD_LIBRARY_PATH environment variable before running application, e.g.,

export LD_LIBRARY_PATH=/opt/intel/mkl/10.x.x.xxx/lib/32:$LD_LIBRARY_PATH

My webcam, which works fine in OpenCV 2.1, could not even be launched in OpenCV 2.2. After some google work, it seems to be a known Bug of 2.2 version and has been solved in the branch but not in the package.

So, just DIY! Only one file needs to be modified: $(OpenCV Folder)\modules\highgui\src\precomp.hpp

Find:

#if !defined WIN32 && !defined _WIN32
#include "cvconfig.h"
#else
void  FillBitmapInfo( BITMAPINFO* bmi, int width, int height, int bpp, int origin );
#endif

Replace:

#include "cvconfig.h"
#if defined WIN32 || defined _WIN32
void  FillBitmapInfo( BITMAPINFO* bmi, int width, int height, int bpp, int origin );
#endif

Re-compile OpenCV project, and done.

Task 1: Chinese Support

After searching through the google, I finally select a solution: A software named FontRouter with the use of some Unicode Fonts.

FontRouter is some Font Driver Software, the homepage of this project is http://code.google.com/p/fontrouter/ , on which the certain version can be found (Nokia E71 use S60 3rd. system, so choose the version for Symbian 6). By the way, the downloaded software may need to be signed before the installation on mobile, since it is really common situation for Nokia user, I don’t think it is difficult and many solution for this can be easily found on internet. The Unicode Fonts can be selected totally based on your favor, and what you have to do is only to download it and save it in the special folder for FontRounter in Mobile.

Restart the mobile and Chinese is available, of course with the UTF-8 coding, which is also common, at least I get no trouble with email and google reader.

Task 2: Softwares

As my mostly interests on mobile focus on the application with internet and reading, so I pick a list of the softwares I used in my E71:

S01. fring : A famous IM software on mobile, which can use the accounts of Skype, MSN, Twitter and so on at the same time. For me its task is using voice call with skype using 3G or  wifi. You can download it from http://www.fring.com/

S02. Mail for exchange : A software from Nokia website, which can make the connection between mobile and exchange server. I use it to connect to google service to sync my contact list and calendar. You can find it on nokia’s site.

S03. Google Mobile ：A set of google tools, from which I can easily use Gmail, Google Maps and Google Reader. You can download it from  http://www.google.com/mobile/

S04. twittai ：A Twitter client software, which have almost all the basic function of twitter and well support for Chinese. You can download it from http://www.twittai.com/

S05. Baidu Input ：A chinese input software from Baidu, You can download it from http://ishouji.baidu.com/input/

S06. Youdao Dictionary on mobile ：A mobile dictionary from Neteast, which have the abilities for online searching and words acquisition from camera. You can download it from http://m.youdao.com/help/cidian
