Hi. This is James Cook of the University
of Maine at Augusta and this is the
first video in a series showing
you how to take a small cheap computer
called a Raspberry Pi and use it for
social media data mining and analysis.
Now, the Raspberry Pi is a really tiny,
really inexpensive computer. This is
what it looks like. This is a Raspberry
Pi 2; it is currently the most advanced Raspberry Pi
that they have going around and it costs
a little bit more than $30. You can get a
Raspberry Pi that will do most of the
same things that we're going to do in
this series called the Raspberry Pi Zero
for a mere $5, but we're going to work
with this Raspberry Pi 2 today. In order to get this computer to work you're going to need a
little bit more than a mere board. You're
going to need some memory, something
called NOOBS (New Out Of Box Software), a micro SD drive here not the big one but
the little one.  You'll need, possibly, a case to keep everything from getting damaged. If you
want to communicate to the internet you
gonna need something called a USB
dongle. Believe it or not this little
tiny thing can connect you to the
network if you have a home wi-fi network which I'm going to assume you have. You are going to
need a power supply. You'll need a mouse
and a keyboard. Each of these
elements can be purchased for something like $10. Finally, you are going to need to hook up
to some kind of monitor. Now most modern TVs have a HDMI slot, and that's what we're
going to hook up with today, using a HDMI cable. There are other solutions for obtaining video output that are out there; you
can look them up on the internet and they are a little more complicated. The HDMI setup method is very
simple so we will use that here. There's an order for connecting up your gear once you have it all at hand.
The first thing you need to do is take this
microSD card out of its box --
not the big one, but rather this little chip here -- it has 8 gigabytes of memory on it and it is the size
of my smallest digit. Wow. It's really
hard to find the slot for the Micro SD card but it's on
the bottom and it's hidden right there
right underneath this bit here. You have
to look around for it but I'm going to
insert that in very gently and wait
for it to make a tiny click. That was it; it's in!
There's your installation of memory. How
could it be simpler?
Well, now, you could have a mouse. It should be a USB mouse, a mouse with a USB cable.
The Raspberry Pi has four USB slots. Let's insert the mouse into its slot.  You may
notice I'm holding the board by the edges. I don't want to touch the actual circuits.
There, it's clicked in. Now I do the
same thing for a USB keyboard's cable.
I'm doing this at home because this is a
home project, really, right? You can now do
data mining at home.  No need for a fancy lab. Now we have a mouse and a keyboard connected, what's next? The next thing you're
going to want to hook up here is a HDMI video cord. I'm gonna go over to the side of my
TV and I'm gonna look for the HDMI slot.
I've hooked the cable in there and then I am going to find the HDMI slot here on the Raspberry Pi. Fortunately, you should notice there's
lots of little writing on the board. There's
an actual label that shows you where the
HDMI slot is (right here). Plug
that in; this is what they mean by
plug-n-play, right? What could be simpler?
The last thing, now, the last thing I need
to do is to take my power cord and I should
only have that hooked up when everything
else is ready. Now, for later installments
in the series, you'll see my Raspberry Pi in a case for its protection,
but I wanted you to see the innards today.
Now this power cord is the same kind of power cord
that would be used to run a typical
non-Apple phone, and you'll see there's a
source for power in there. I'm plugging in my power cord very carefully in. Right! Now I've got a
little power signal there and I've got the Raspberry Pi loading up and ready for software installation. In our
next video, we're going to take a look at
how to login for the first time and it's
actually quite simple.
