Free Raspberry Pi

I was surprised earlier this year when I signed up for a trial to monitor some of my servers.  With this sign up I was told I would get a free t-shirt and Raspberry Pi.  I got the t-shirt within a few weeks, but I didn’t think anything about the Raspberry Pi.  I was amazed in July when I opened the mail to find a brand spanking new Raspberry Pi waiting for me.  Not only was it free but it was the latest and greatest Raspberry Pi Model B+.

Since I already had 2 Model B’s I hadn’t planned anything to do with this new one.  So now that I am starting to get some free time I thought I needed to figure out what to do with this new one.  So what to do with it…hmm….the possibilities are endless.  I could:

Why not try multiple options, cause they all sound really good. I have decided to start with the simplest one, making a wireless network range extender.  I have also added a Parallax 16×2 LCD so I can start teaching myself other things.

I have set-up one of my Raspberry Pi’s to be a War-Pi Sniffer.  More on that one later.



Ever since I first got my Raspberry Pi I knew I wanted to set-up a wireless sniffer.  My goal was to create a small sniffer that was able to be transported in my car so I could sniff wireless networks and map their locations.

I started by looking all over the web to find as much information as I could about others that had already done this.  I found a few sites, like this one and this one.  Although I found this paper to be the best as far as documenting the whole process.

Now that I have gotten my rig set-up it’s time for some testing… that’s what I did.  I hopped in my car turned on the WarPi and drove around sniffing for networks.

Yeah….I got some results.  Now how do I use this information???  I knew I wanted to view the finding on Google Earth.  So I used the script in the document.  Once I have converted the files I am able to view the networks in Google Earth.

One of the things I wanted to do was help automate the process of getting my Kismet logs to a Google Earth files.  I created the following script to transfer the files from my Raspberry Pi SD card to a more portable storage media.


DATE=$(date ‘+%m-%d-%Y’)

if [ -f $$DEST/Kismet-$DATE ];
python /home/user/Scripts/ –kmz –kml -o $DEST/Kismet-1-$DATE $SOURCE/*.netxml $DEST/
python /home/user/Scripts/ –kmz –kml -o $DEST/Kismet-$DATE $SOURCE/*.netxml $DEST/
rm -fr $SOURCE/*


I was able to find a Polaroid phone charger for only $15.  This gives me the ability to walk around with the War-Pi running for over 8 hours.  Here is my rig.
