So in the course of finishing what would have been part 3 of this project, the post processing, I decided that some design changes needed to be made to the robot. I made two hardware changes: larger drive wheels and the addition of a compass sensor.
Side view.

Since transitioning to Ubuntu Linux, I’ve continued working on my Lego NXT projects. I spent several hours figuring out how to configure my machine to write, debug, and upload code to the NXT brick. I found several sites and message board posts, each detailing a specific step in the process. I thought it would be a good idea to bring all of this information together and hopefully make it easy for anyone else who wishes to follow in my footsteps.
The entire process consists of setting up a Windows emulator (WINE), installing an IDE (BricxCC), and installing and running a communications tool between linux and the brick (Talk2NXT).

I had a frayed power cord to an old lamp laying around and I didn’t want to just trash it.
I came up with my own solution to the Moleskine pen holder problem. As a gift to my friend Bryan, I butchered a Moleskin to stealthily hold nine colored pencils and a pencil sharpener. I found several tutorials on embedding other devices in a Moleskin but found that I had made the same mistakes experiences by the other hackers.
After much nagging from some of my friends, I’ve finally made the switch to Linux. I am starting to realize that the skill set I’m developing is rather substantial and worth documenting. I’ll be taking the time over the next weeks and months to document the software and operation skills that and I am learning. My goal is to provide a list of tasks I can accomplish in Linux and to keep a record of my actions so that I can quickly set up new machines with my preferences. I am not intending this to be a “how to” guide for anyone else, although it may provide some usefulness to someone starting out with Linux.
To start off, I have installed Ubuntu 8.10 on both of my home machines. Each new Ubuntu release is given a name and 8.10 is called Intrepid Ibex. I preformed both installs from a Live CD which allows me to run the OS from the CD-ROM without installing anything. I knew that I would enjoy it immediately so I chose to simply reformat both computers.
