Setting up Raspberry Pi

Great, now you have a Raspberry Pi. Lets get it going.

##Overview

Getting a Pi out of the box unfortunately does not quite give you a working computer. Here we will go over basic setup of the Operating System, connecting to Internet, and getting the Pi in working state.

##General Notes A case on the Pi will prevent the bottom, metal pins from resting on a conductive surface.

You will need a 5V power supply that can support ~2A of current. You can expect your Pi to take between 1-2A depending on the computer's load.

##Heat Sinks Here is an image of why you might want a heat sink. If you do not have them, you should be all right.

Make sure that you use thermal adhesive, and apply to heat sinks to CPU and Network/USB chip.

##Installing the Operating System (Rasbian) Raspbian is the Linux distribution recommended for our device. We will need it to use our computer.

You can purchase a SD card with Noobs installed, or you can follow these instructions to setup your own SD card.

After, insert the SD card to the bottom of the Raspberry Pi, connect HDMI, a mouse, and a keyboard, then power it on.

You should see:

Continue through the Noobs application and your Raspberry Pi should be up and running.

##Basic Setup Keyboard and local time needs to be set up following installation.

Open a terminal, and

sudo raspi-config

###Keyboard Please see here for full instructions and associated pictures

###Timezone and Clock

1. Navigate to "Internationalisation Options"
2. "Change Timezone"
3. Then select country and city

##Connecting to the internet This was a headache for me, hopefully it will not be for you.

Connecting is straightforward if you have a standard wired connection or "select network, enter password" Wifi (see: WPA-Personal).

Things are more complicated if you have a static IP or are trying to connect on Airbears2.

DO NOT change your /etc/network/interfaces file. Forum help for changing this file is for older versions of Rasbian and should be unnecessary.

###Standard Connection

1. Click network button in top right corner
2. Select your network
3. Enter password if necessary

###Ethernet with a Static IP address Note, most ethernet connections will work without these instructions.

You will need an IP address, a subnet mask, a router/gateway, a DNS server, and a domain.

1. Right click network button in top right corner
2. Select "Wifi Network Settings"
3. Configure -> "interface:eth0"
4. Enter information

Here is an example:

NOTE: If your subnet mask looks like: "255.255.255.xxx". we will need to convert to CIDR notation. Please use this tool and paste the CIDR notation address.

###WPA-Enterprise (Airbears2, UC Berkeley’s campus wifi) Airbears2 poses a different challenge. To log in, a username and password is required.
To connect, we will need to modify a network configuration file. The internet recommends to set up Wifi on an Android phone, and copy/paste the created configuration file. For convenience, I have included sample config file.

Open the file with:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

And add the following:

Double check your file, then "ctrl + X" to exit, "y" to save, "enter" to save.

Restart your Pi to reload network changes.

##Once Connected to the Internet

"apt-get" is a helpful installer for a linux machine. We should update the current applications before proceeding. Note that this process may take ~15 minutes. Also, it has frozen before, and I needed to CTRL-Z to exit. Then I rebooted and started again.

Run

sudo apt-get update

And

sudo apt-get -y upgrade

You can install any application using

sudo apt-get install _______
