[Hi-Cost Performance]3.5inch Touch Panel Screen for Raspberry PI

(I am sorry by update this blog after an interval of about one year.)
I bought it on impulse for a price.



There are a case ; and this price!!!!!
(The SD card had the thing which I bought in Japan)
"Buy cheap and waste your money." (I thought so...)














There was some dissatisfied points.

About CASE
"Where is MANUAL?"





It is on the back side of the box.
(I didn't notice it.)

One screw which fixes the main body of RP and the undersurface of case
was not match the size!!

Nut was a little bit big , after assembling, flew when stirred up. (Hahaha)
Because there is no help for it, I float only the left bottom end.

And parts for reinforcement in case.(?)

When I look from the top, it was warped a little?
It was slightly diagonal for a case.

That's you all right!! "MADE in RPC"

It bundle the touch pen.

The problems was
Because this case blocks up the GPIO pin, to use it with a control system,
You remodel the connector part, and yourself cannot but make a hole.

There is not the feeling involved in so badly.
I cannot say the buying, but It is "the cheapest", and you can make it.




This is a Full HD type. (Higher evoluation)

’GHIBLI' art museum in Japan

There is 'GHIBLI' art museum in Japan.
http://www.ghibli-museum.jp/en/


A ticket is a reservation system of a time specification.
HAYAO MIYAZAKI who retired from making a movie is pouring passion now.
(He's making is the inner showpiece and the short movie shown only there.)

We went last year.

TOTORO and a cat bus were also there.

Microsoft Wireless keyboard All-in-One Media Keyboard N9Z-00001 review

I was looking for compact wireless keyboard.


There is variously a wired and USB-type, but it's very small,
The compact wireless one is very difficult to hit with my large finger.
(I'm Japanese, but I'm taller more than 180cm. So my hand is large like you.)

I found something very good.

The key pitch isn't so different from a usual one (18 mm),

and the stroke is rather short little.

But if that's the carrying purpose, I can be convinced.

The trackpad is bigger entirely than that of a laptop computer,
so it can be operated at room.

Though wireless is the 2.4GHz bandwidth original,
the communication is coded in AES.
You do not have to worry about the crack.

There is Program Function key n and a custom key also.
It is more inexpensive than I thought.

(Worrisome point)
 There are no stand, so the person who tilts and strikes it may need a stand.
 The place where a wireless module is stocked is the same place as a battery location.
 When carrying around, so I have to open a back cover one by one.
 (It's hard and maybe it's breaks.)

It's ordinary to be able to use it by Windows/iOS/Linux.

I'll add that even Raspberry PI could use it.

OCR doesn't need professional software. It's made of only a web!

I thought OCR was something to do by professional software.

Did you know that it was possible only by a web?
(Is that old information?)



1. It's able to take a photograph. And it can be connected to the Internet.

2. Google Account

Something you'd like to convert to the text data, you take a photograph.

You upload that photograph to Google Drive.

Go to Google Drive from web browser.

There is a photograph which uploaded you.

And the picture is right-clicked.

"Open with" and "Google Docs"


















A photo was being indicated by Japanese OS, but I did using the English OS actually.
(There is strange words a little. ;-)

To make character correctly, you should cut that picture or you should make only the part you would like to make read.

That is FREE! Wonderful.

I succeeded to reduce Windows 10 IoT Core for RP2 to a SD card of the 4GB and start RP2 by that.

Windows 10 IoT Core image of Raspberry PI2 is 8GB.
It's requirement.


More than 8 GB of microSD card is needed by default, whether it fits into 4GB, trial and error were repeated.

The microSD card I got at a show before (4GB).
It was free!









First an image is ordinarily wrote on a SD card (more than 8 GB).
(When there are no SD cards, even a USB memory is possible.)

Using a free partition tool, the partition size, shrink, it was seen using this in case of me.



The usual size is










I do size change using Tool.












MainOS and Data, shrink and it'll be the size within the 4GB.


An image is taken out once and it's copied in a SD card of the 4GB.


















It booted!!

I say that "It's scarce in practicality"....

Windows 10 IoT Core for RP2 will be install in Raspberry PI 2 (Windows7).

Windows 10 IoT Core for Raspberry PI 2
http://go.microsoft.com/fwlink/?LinkId=619755

It's burned or the mount is made a CD in Virtual and it's installed in Win7 machine (PC).

It's normally,

C:\Program files (x86)\Microsoft IoT\

That folder is made.


C:\Program files (x86)\Microsoft IoT\FFU\RaspberryPI2\flash.ffu

Tool including burning on a SD card (front-end of dism.exe / WindowsIoTImageHelper)is also installed.
But, It doesn't work well on Windows7 (x64).

I tried from a command prompt directly.

dism.exe /Apply-Image /ImageFile:..\FFU\RasberryPI2\flash.ffu /ApplyDrive:\\.\PhysicalDrive2 /SkipPlatformCheck

(PhysicalDrive? is a drive number of SD card.) 

Error: 740
Elevated permissions are required to run DISM.
Use an elevated command prompt to complete these tasks.


Error. 
Is execution needed by an administrator right?

A command prompt was opened by an administrator right. and I tried again.

Error: 126
An error occurred. DISM could not be initialized in the local folder.
Ensure that DISM is installed correctly and that all of the binaries are present.


It doesn't work...

There is also a way to take dism.exe out from an installation im
age of Windows10 and do.
I'm going a different way.

A ffu file is converted to a img file, and that's burned by another tool,

"cygwin (or cygwin64) " is installed on 7 machines and "python" is installed.

ffu2img.py  that script execute.


$ ~/ffu2img.py flash.ffu Windows10_IoT_Core_for_RP2.img
Input File: flash.ffu
Output File: Windows10_IoT_Core_for_RP2.img
Block data entries begin: 0x800f8
Block data entries end: 0xa6098
Block data chunks begin: 0xc0000
9721 blocks, 1244288kb written - Delay expected. Please wait.
Write complete.


FFU file was converted to a img file.

This img file is burned on a SD card at Tool as "Win32DiskImager".




If it's completed, a microSD card is placed in RP2 and it's started.


I'll wait for an initializing process and start it about 10 minutes later.

How to dual-boot "Ubuntu and Android-x86" on ASUS EeePC 901

Anyway, I succeeded.

Once, both of the SSD 4GB and the 8GB were cleared.

Android was installed to the 4GB.

I made another partition that it's about 200MB from the head.
Android is installed in a remaining partiton.

The format isn't made of an installer of Android for some reason.

http://knoppix.technic3d.com/knoppix/KNOPPIX_V7.0.5CD-2012-12-21-EN.iso

Knoppix is uesd.

To create and format a partition with "GParted"

※ The format of sda1.
A picture, Fat32. The case only of Linux is OK in ext2, ext3 or ext4.

Android is installed in sda5.









https://yoshinobu968.blogspot.jp/2016/06/how-install-android-x86-to-asus-eeepc.html
※ The installation which is GRUB2 by the past article, Skip, this time is Yes.

After installation completion, once, shut down.

Ubuntu install by a USB memory.

https://yoshinobu968.blogspot.jp/2016/06/how-install-xubuntu-1404-lts-trusty.html














The point in which you install Ubuntu is to assign "/boot" to the first partition (200MB) and assign "/" (route) to 8GB SSD.

Both of them are formats of ext4.
The 8GB also sets up the swap partition of the 1GB, and, "/" is 7GB.

At the first, I tried to move another partition with "boot-repair".
But it didn't work after all.

The setting change which is GRUB after a Ubuntu start from a terminal.

$ vi /etc/default/grub

Following setting, comment out.

#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true

After it's saved,

$ sudo update-grub

When it restarts, the menu comes out.














But only Ubuntu can be chosen in this case.

"grub-customizer" is used to establish it easily.

On a terminal on Ubuntu,

$ sudo add-apt-repository ppa:danielrichter2007/grub-customizer
(You need input Enter later.) 
$ sudo apt-get update
$ sudo apt-get install grub-customizer
$ sudo grub-cutomizer


like this.

It's chosen "Edit", "newly",

 Name:Android-x86

 The type: and other things


Boot Seauence is 

there is a volume with Android in a desktop first, so it opens that.

menu.lst is in the grub folder, so that will be opened.
That is the grub menu when you installed Android.

Necessary is the line of "kernel" and "initrd".
The contents of the "Boot Seauence" of grub-customizer new setting consult menu.lst.

set root=(hd0,5)
linux /android-4.4-r5/kernel quiet root=/dev/ram0 androidboot.hardware=android_x86 SRC=/android-4.4-r5
initrd /android-4.4-r5/initrd.img

Save and reboot.















Android could be started with no problem.
