By Land, Sea and Nokia GPS to Orcas Island

I am sitting in my room at the Orcas Hotel on Orcas Island.  While on vacation this week I had a chance to try out my Nokia N800 with my new Navibe portable GPS unit. Surprisingly, I discovered that this combination delivers better GPS performance than the N810. During this vacation we tested the two units side by side, and found that when a car was moving at 70 mph, the N810 had difficulty getting a GPS lock. The N810 could take ten minutes, while the Navibe unit linked to my N800 locked onto the satellites almost instantaneously (we own both a 800 and 810 so that both of my sons could Skype us this Summer while overseas). It is worth noting that the N810 was able to establish a GPS lock quickly if our car was not moving.

Obviously one wonders why the N800 outperforms the 810. My guess is the Navibe unit which my kids gave me for my birthday ($45) has a stronger GPS receiver than the embedded unit in the N810.  Thus, if the N810’s keyboard is not a selling point for you … avoid the higher cost and take this route!

The entire prcess works quite well. I just program in some "favorites" and "way points", and even without a paid direction finder service like Wayfinder, my Nokia helped me navigate. If I ever get lost, I just enter the command find current location, and then zoom out to find a road that I recognize.

I leave you with some screenshots from my trip … the South Bay B&B at Lake Whatcom in the Cascades to Orcas Island … including the ferry ride. (this entire post was entered using my Nokia N800)(see some real photos of our trip to the San Juan Islands)

Tracking Ships in their Ice Water Mansions

I'm on vacation for the next week. Thus, you'll pardon me if my posts … although still having a technical flavor, take upon less of a work focus. Today I bring you tracking sailing ships on the high seas (or the Great Lakes). Most folks know you can track commercial airplanes in flight, but did you know similar services are available for large ships?

This morning we head a few miles north to my home town of Duluth, Minnesota. The harbor ice is starting to disappear thanks to the efforts of the USCG Alder. Now … let's track some ships: (my thanks to Gordon Lightfoot … the inspiration for today's title)

NanoHype

Nanotechnology is one of the techie disciplines which popular media has seized upon. Spiderman’s suit in the famous comic books and movie series supposedly gives him super-human strength and powers. In sci-fi novels, like Prey … written by Michael Crichton (Jurassic Park):

In the Nevada desert, an experiment has gone horribly wrong. A cloud of nanoparticles—micro-robots—has escaped from the laboratory. This cloud is self-sustaining and self-reproducing. It is intelligent and learns from…

This begs the question … what is hype, and what is nano? Link to this Northwestern University site and learn more! Spend some time exploring and you’ll even find information about Grey Goo! In summation, this site is worth adding to the Engineering Learning Wiki.

A Mathematical Leprechaun

So you think you’re good at math? Prove it! One of my favorite sources for MatLab tutorials, Blinkdagger, just started a bi-weekly math contest.

There are 1000 engineering-centric Leprechauns, all of whom are members of the prestigious group, Mensa. Each of the Leprechauns have an extremely high IQ (top 2% among the general population) and each Leprechaun is fully aware that all the other Leprechauns are also members of Mensa.

One day, the Leprechauns receive news that there is an abnormally large pot of gold at the end of the rainbow near China. All of the Leprechauns rush to the end of the rainbow and arrive simultaneously. In this situation, according to Leprechaun Lore, the treasure is to be divided by the following manner …

Engineering Congratulations from #4 to #1

John Hunter just posted that his Curious Cat Science and Engineering Blog is now the # 1 Google result when one queries <engineering> + <blog>.

Congrats from # 4 on the wiki side of the equation (i.e. me). My Engineering Learning Wiki is the # 4 Google result if one queries <engineering> + <wiki>. Wikipedia is my chief rival (results # 1 and # 2)

Hey, John … Wikipedia doesn’t have an engineering blog … unfair competition!
