Learning with Raspberry PI, Delivery I – Start-up: record in SD card

About a year ago that I have a small Raspberry PI, You can have many utilities, as many as a computer with GNU/Linux, Since that is precisely.

imagesI have learned a lot with this small plate, many things that I have then been able to implement in virtual machines or actual machines.

The model “B” Raspberry IP it looks like:

It has a 700 Mhz CPU, GPU Broadcom Videocore IV, 512MB of RAM (shared for CPU and GPU), outputs GPIO , Jack 3, 5mm, HDMI and tickets 2xUSB 2.0 and Ethernet, It also has screen expansion slots LCD and camera, so it could be used even in IP camera.

Differences between model “TO” and model “B”:

Complete schema of the model B:

The power is made by a micro cable USB conventional, so it will serve any charger or cable USB Mobile, with output of 5V 1A (If you are going to connect USB HUBS to your Raspberry, Remember to always use a HUB with external power supply):

To solve the lack of WiFi, We have small and economical solutions, as this antenna USB TP-Link at a price of 7.90€ (You can Google search the model with the reference that may be recorded in the aluminum of the USB):

To make it work, We have to burn the image of an operating system for Raspberry, in this tutorial I will be based in Raspbian, as it is based on Debian, allowing me to apply my knowledge in this distribution, and get the maximum juice to the Raspberry.

But you have a list of available operating systems for Raspberry PI in the following link:

To do this I used USB-imagewriter, Since the files have extension .img

First download USB-imagewrriter from the following link:

Download the latest version, in our case the 0.1.99 and we descomprimiremos it:
Execute the script install.sh from terminal, Suppose that we have unzipped in a folder called USB-imagewriter-0.1.99 on the desktop:

usuario@maquina:~$ cd/home/nombreusuario/Escritorio/usb-imagewriter-0.1.99
usuario@maquina:~$ chmod +x install.sh
usuario@maquina:~$ sh install.sh

If we have problems, probably by permissions, We have to do all this as root.

To my personally the script not worked, so I extracted the contents and execute it manually from Terminal:

In terminal type the following, extruded “with tweezers” of the script:

usuario@maquina:~$ cp share/applications/imagewriter.desktop /usr/share/applications/
usuario@maquina:~$ cp imagewriter /usr/bin/
usuario@maquina:~$ mkdir -p /usr/lib/imagewriter
usuario@maquina:~$ mkdir -p /usr/share/imagewriter
usuario@maquina:~$ cp lib/imagewriter.py lib/find_devices /usb/lib/imagewriter
usuario@maquina:~$ cp share/usb-imagewriter/imagewriter.glade share/usb-imagewriter/header.png /usr/share/imagewriter/

If I want to uninstall, We would only have to run the following commands:

usuario@maquina:~$ rm -rf /usr/lib/imagewriter
usuario@maquina:~$ rm -rf /usr/share/imagewriter
usuario@maquina:~$ rm -r /usr/share/applications/imagewriter.desktop
usuario@maquina:~$ rm -f /usr/bin/imagewriter

Now you can open the software and record our disk image in the SD card:
The following delivery, We will see how our first steps with Raspberry, How to optimize it, and as you use as a secure server of SSH, SFTP, VNC, and even how to configure it to access our network from the internet through the safely.
