The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The Raspberry Pi is manufactured in two board configurations through licensed manufacturing deals with Newark element (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online. Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red coloring and lack of FCC/CE marks. The hardware is the same across all manufacturers. The Raspberry Pi has a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded to 512 MB. It does not include a built-in hard disk or solid-state drive, but uses an SD card for booting and persistent storage. The Foundation provides Debian and Arch Linux ARM distributions for download. Tools are available for Python as the main programming language, with support for BBC BASIC (via the RISC OS image or the Brandy Basic clone for Linux), C, Java and Perl.
What is a Raspberry Pi
Raspberry Pi is a series of small, single-board computers developed by the Raspberry Pi Foundation in the United Kingdom. These computers are designed to be affordable and accessible to anyone, with the goal of promoting the teaching of basic computer science in schools and developing countries. Raspberry Pi computers are small, about the size of a credit card, and they can be used for a variety of purposes, including building home media centers, programming, and creating DIY electronics projects.

Some useful tips & tricks on working with Pi:
How can I add and share printer connected to Raspberry Pi in my local network:
Unlike a typical Windows machine, the little Raspberry Pi running Rasbian doesn’t exactly come with plug’n-play printer support. We need to install and configure printer support manually. To do so, open a terminal window, then insert:
sudo apt-get install cups sudo usermod -a -G lpadmin pi sudo nano /etc/cups/cupsd.conf
cupsd.conf look for line
#Listen localhost:631 and change it to
Port 631 to have access to your Pi printer server from your local network rather than just Pi itself. Now in the terminal type:
service cups restart
You can now access to the Pi’s printer settings from: http://raspberry-pi-ip:631
Adding a Printer to CUPS
When you first navigate to http://raspberry-pi-ip:631, you’ll see the default CUPS homepage. The section we are interested in is the
Administration tab. Click on it now.
Within the Administration panel, click add printer. If you receive a warning about the site’s security certificate, go ahead and click proceed anyway to ignore it. You’ll be prompted to enter a username and password.
Go ahead and enter the username and password of the account you added to the “lpadmin” group earlier in the tutorial and click “Log In”.
After logging in, you’ll be presented with a list of discovered printers (both local and networked). Select the printer you wish to add to the system:
After selecting the printer, you’ll be offered an opportunity to edit the name, description, and location of the printer, as well as enable network sharing. Since our printer is already a network printer, we left “Share This Printer” unchecked:
After editing the printer name and adding a location, you’ll be prompted to select the specific driver you want to use for your printer. Despite the fact that it automatically discovered the printer and the printer name, CUPS makes no attempt to pick the right driver for you. Scroll until you see a model number that matches yours. Alternatively, if you have a PPD file for the printer that you have downloaded from the manufacturer, you can load that with the “Choose File” button.
Login to your Raspberry Pi using your public key instead of password authentication:
The first step is to ensure that you have a public private key-pair installed on your local machine. Most developers will already have this but in linux or mac you can normally generate a new pair using:
ssh-keygen -t rsa -C "[email protected]"
I won’t cover creating these in any detail as there are plenty of guides available. Github’s guides cover this as a side effect of setting up git here and an issues helper here.
Now copy your public key to
~/.ssh/authorized_keys in your Raspberry Pi machine. Now we should be able to login using:
This time we shouldn’t be asked for a password it should use the key instead!
How to configure Raspberry Pi to have an static IP address:
It is usually more convenient to setup Raspberry Pi to request an static IP address on your network. This way, you can easily access to the Pi without the need to use a IP scanner tool.
To make your Pi requesting an static IP, open a terminal window and follow:
sudo nano /etc/network/interfaces
Remove the line that reads (iface eth0 inet dhcp) and add the following:
iface eth0 inet static address raspberry-pi ip (i.e. 192.168.1.2) netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.254
But how did I come up with these numbers. To get the numbers boot into Raspian and log in. First, we need to list the network interface we currently have available:
iface eth0 inet dhcp implies that we’re currently getting out IP address via DHCP, meaning it’s being dynamically registered by the router. This is what we want to change! To gather the information we need, first of all we need to grab some information from our router and Pi. There’s a couple of command we need to run to get this info. The first commend to run is
ifconfig. This reveals your router information, the bit you want is after eth0 (the ethernet connection)
eth0 Link encap:Ethernet HWaddr b8:27:eb:b3:fc:2c inet addr:192.168.1.81 Bcast:192.168.1.255 Mask:255.255.255.0
Write down the following information:
- inet addr – 192.168.1.81 (Pi’s Current IP Address)
- Bcast – 192.168.1.255 (The Broadcast IP Range)
- Mask – 255.255.255.0 (Subnet Mask Address)
We need a little more information before we proceed. Use the command
netstat -nr. From the output of this commend with need
- Gateway Address – 192.168.1.254
- Destination Address – 192.168.1.0
That’s pretty much it! Now reboot and check your changes.
Changing the default username and password or edit local time setting
The simplest way to change the password of the default user in Raspbian is to make use of the
raspi-config administration menu. This will need to be run as root. To achieve this we can log on as the user pi with the password of raspberry. These are the default user and password. To run
raspi-config with root permissions, we preface the command with sudo:
Now browse through the options and change password or time settings.
Using Raspberry Pi as a BitTorrent client
Although there are several BitTorrent clients available for Pi, here we are using Transmission. Open a new terminal and follow:
sudo apt-get install transmission-daemon. mkdir /media/storage/torrent sudo nano /etc/transmission-daemon/settings.json
settings.json modify the following lines:
"download-dir": "/media/storage/torrent/complete", "incomplete-dir": "/media/storage/torrent/incomplete", "incomplete-dir-enabled": true, "rpc-whitelist": "*.*.*.*",
Now its time to reset the BitTorrent client
sudo service transmission-daemon reload sudo service transmission-daemon restart
That’s it. Access to your torrent client from http://192.168.1.2:9091 (considering Pi’s IP is 192.168.1.2)
Adding USB storage support to Raspberry Pi
If you have already followed the BitTorrent configuration, you most certainly need to attach a mass storage to your Pi and setup the BitTorrent client to use this storage for storing files. Open a terminal window and follow:
sudo mkdir -p /media/storage. sudo mkfs.ext4 /dev/sda1 -L storage sudo blkid
Here we have used
blkid command to find the USB’s unique ID. Let’s consider the ID is
Now to support USB drive with FAT partition use:
sudo nano /etc/fstab UUID=f5a99a89-5db1-40a2-a038-6186075b85fd /media/storage ext4 rw,noauto,users,uid=1000,gid=1000,permissions 0 2'
and for NTFS partitions use:
sudo nano /etc/fstab UUID=f5a99a89-5db1-40a2-a038-6186075b85fd /media/storage ext4 defaults 0 2
Now let’s take care of permissions:
sudo chown nobody.nogroup -R /media/storage/ sudo chmod 0777 /media/storage/ sudo mount -a
To have access to the sotrage from other computers in your network install
samba as follows:
sudo apt-get install samba sudo apt-get install samba-common-bin sudo nano /etc/samba/smb.conf
Add the following to share our newly added disk driver over network:
[storage] comment = USB Storage path = /media/storage writeable = Yes only guest = Yes create mask = 0777 directory mask = 0777 browseable = Yes public = yes
sudo service samba restart. You should be able to access your storage from all local computers by now!. To get information about how much disk space is used in your USB drive use
df -h /dev/sda1
Compatible Operating Systems (OS)
There are several operating systems (OS) that are specifically designed to run on Raspberry Pi, including Raspbian, Ubuntu Mate, and OSMC (Open Source Media Center). Raspbian is the official OS for Raspberry Pi and is based on the popular Linux distribution Debian. Ubuntu Mate is a version of the popular Ubuntu Linux distribution that has been optimized to run on Raspberry Pi. OSMC is a free, open-source media center that is designed to be used on Raspberry Pi and other devices. Other popular Linux distributions, such as Fedora and Arch Linux, can also be installed on Raspberry Pi, but they may require some additional setup and configuration.
