Setting up the SD Card

The First and the most important part!

For Windows and Linux

Windows


Well I am using an 8 GB SD Card but even a 4 GB card is sufficient. For windows I shall use Win32 Disk Imager to burn the image to the SD Card. And for Linux a simple $dd command will do the job.

Link to download Win32 Disk Imager:


Now lets get started!

Extract the .zip file that you just downloaded from the previous post Getting Started

Run the Win32 Disk Imager:



Click on the browse icon as shown in the figure above (in RED) to open the window that follow!
Browse to the location of your download image file and click "Open".

Choose your destination SD Card under the "Device" list and select the appropriate alphabet carefully
(NOTE: Be careful whilst following this procedure so that you do not format any of your hard drives)

Click on "Write" button on the Win32 Disk Imager. It will take over 15 minutes (approx.)

Now, you are ready with the bootable SD Card with Raspbian image(or the respective OS you downloaded).


Linux AND Mac

For Linux and Mac we simply use the $dd command OR 

For Mac we have Disk Imager that can be downloaded from:

Disk Imager and follow the steps similar to the windows' method of writing the file.

For people with familiarity in using the Terminal, I think the $dd command will be simple to use, ELSE
I recommend you to download and install "Wine" to run the Win32 Disk Imager on any Linux platform.

The $dd command:


We use the options if (Input file) and of (Output file)
Type in $ls /dev/sd*
This will let show you the name of your sdcard. Type in:
$dd if=<raspbian_image_file_location> of=~/dev/<sdcard_name>

That's about it!

Stay tuned for a Video Demo of the same:)

Getting Started!

The Raspberry Pi


Well yes, as all of you know the Raspberry Pi is another one of those micro-controllers available for projects, BUT what makes it unique are the features it offers at a nominal price of $35 on Element14 or around Rs.3000/- in India.

So why the Pi?

Though there are other micro-controllers available, Raspberry Pi provides a complete Desktop experience when connected to a TV or a monitor. This way its very flexible in-terms of being handled by newbies or kids. 
 
   

Why this blog?

Wonder why I recommend reading this blog?

Well, I found quite a lot of user guides and videos about Raspberry Pi, but not both!
I began experimenting with the Raspberry Pi since a month now. I wanted the Pi to work for Home Automation which I would say I am 50% done with.
Anyway I don't want you guys to look around multiple sites and download multiple pdf's and have you searching YouTube for everything. I shall along with the blog link you all to my YouTube channel where I shall guide you into every aspect of the Raspberry Pi and help you with your projects! 

What to use the Pi for?

Well most programmers use the Pi for lots of creative projects and others use it as a media player as well. There are different Operating Systems that are designed and are stable for different purposes such as:
  1. Raspbian "wheezy"
  2. Soft float Debian "wheezy"
  3. Pidora
  4. Arch Linux ARM
  5. RISC OS
  6. Qton Pi
  7. XBMC 
I will focus on the use of Raspbian "wheezy", since this is the OS that we need to work on our projects.
Download the ISO image from the following link:


Its around 430MB,
and for those who are looking for media centre application of the Raspberry Pi, you can choose your downloads from the following link:


Another best OS compatible with the Raspberry Pi is XBMS and you can download it from here:


Next, I shall show you how to make the OS that you chose, a bootable OS on your SD card.
Stay tuned!
