Well I am back from the dead, I guess. I have been on a hiatus since my last post due to work issues. I have been trying to come up with some new ideas for posts and things to do with my RPi. I found a few articles on making a nature camera/stop time animation camera. I unfortunately do not have the RPi camera module for my Pi’s. I do however have a USB camera that works pretty well. I have been playing with it on my Pi for a while and thought I would build my own nature Pi Camera.
So I started off with my basic Pi and then added the camera and battery pack. So now my little system is portable and easy to setup. Thankfully I have a good size battery so my camera will run for a number of hours on just the battery. It typically runs over 8 hours when I am just doing wireless network sniffing with my GPS and Wi-Fi dongles attached. So I should be okay for just as long with only my camera connected. I will follow this article up with additional information about my new time lapse camera setup, including scripts.
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…..so 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 netxml2kml.py 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.
if [ -f $$DEST/Kismet-$DATE ];
python /home/user/Scripts/netxml2kml.py –kmz –kml -o $DEST/Kismet-1-$DATE $SOURCE/*.netxml $DEST/
python /home/user/Scripts/netxml2kml.py –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.
