Welcome! I am an engineer, programmer, designer, and gentleman. You may be interested in some of my electrical and mechanical projects. Take everything you read here with a grain of salt and remember to wear your safety glasses.

The Pipe Crawler—A Hit in Poland?

One of my recent google searches about pipe-crawling robots brought up this link, which appears to be a translation into Polish of some of the documents I wrote about my senior engineering project. It includes pictures from both the pipe crawler web page and the final report we submited to our professors. I should thank ... er ... somebody, though I'm not exactly sure who. They appear to be a lab or research institute of some kind. Well, thanks for the translation anyway!

I'd also like to take a few words here to insist that my friends Sheraz Wasi and Mark Miller be credited as co-authors of the Pipe Crawler work. It seems like my name is the only one that gets attached to it anymore, because I wrote and hosted the web page about it, and that's not fair; both of them toiled away in the robot lab from morning to midnight just as I did. By the way, this is not a criticism of my new Polish friends—many web sites and email correspondents get the impression that I was the only author simply because the page happens to be hosted at www.eikimartinson.com, and this seems like a good opportunity to set the record straight.

The Need for Speed: eikimartinson.com Moves to mediatemple.net

As of yesterday this site is now hosted at Media Temple on my own "Dedicated Virtual" server. It's not exactly a true dedicated server, but it appears as such to me - I get a root login and the ability to reboot the "machine". I get statistics based on Apache logs (something my old service, csoft.net, did not provide for shared hosting). I'm a good deal more insulated from all the other users than I would be on a shared service, which is good for application performance, reliability, database security, etc. But best of all, regular users of this site will notice load times have shortened by a factor of 5!

LED Mortarboards—Technology Marches On!

I would like to bring to the attention of my readers an impressive technological advance made by one David Worden, lately graduated from the University of Wisconsin with a well-deserved degree in Electrical Engineering. Mr. Worden enlivened his graduation ceremony with a light show built into his mortarboard: 64 LEDs driven by a microcontroller programmed to produce a variety of animated effects. Let me be the first to congratulate Mr. Worden on his splendid achievement in Mad Science—but as a Mad Scientist myself, let me also remind the young upstart that he was not the first to have this idea!

In the long-past days of my miss-spent youth (err … 2004), I also graduated with a degree in Electrical Engineering, and sported a light-show hat of my own at the ceremony. The mortarboard had four diagonal lines of 8 white LEDs each, controlled by a central PIC microcontroller; all five circuit boards were painted black and atttached to the top of the hat with velcro. Though I must admit, Mr. Worden's design is rather more complex, with twice as many LEDs as mine and a fully-concealed circuit.

Visual Navigation by Looming Simulation

As a small project for my Inventive Thinking class, I worked on a simulation of creatures avoiding each other or performing tasks like crossing a street or forming a swarm. The creatures navigate by choosing simple actions (like turning right or left) based on the "Looming" principle of obstacle avoidance studied by my thesis advisor, among others. The simulation runs in your web browser (Firefox or recent IE have been tested, but probably others as well). You can view it (fun to watch) and play with the parameters to your heart's content at this link: Looming Simulation

I Move From WYSIWYG to Real Typesetting

Not long ago I began writing my Master's thesis, and fortunately took a moment to consider what might be formatting 'best practice' before I got too deep into what will probably be the longest text I've ever written. Of course, most students these days write reports, theses, dissertations, and everything else in Microsoft Word, or (if the student is poor or motivated by hatred toward Microsoft) one of the free clones of the same. But I decided instead to try something I've long been meaning to try: the TeX typesetting system, or to be more precise, the LaTeX language built on top of TeX. I learned some important lessons from this.

To use (tongue only somewhat in cheek) my new favorite metaphor, Microsoft Word is like the Persian Empire: decadent, soft, corrupt, encouraging of mysticism and lazy thinking. Whereas LaTeX is like Sparta: cold, clean, hard, disciplined, rational. And outnumbered 2000 to 1.
