Grads Visit

In a previous entry to this blog I mentioned that Matt Hilden, class of 2002 would be visiting. He did, and in a busy week full of good surprises, I enjoyed spontaneous visits with Josh Mulder class of 1997, and Brandon Karlsgdt, class of 2005 too. Matt and Brandon were able to meet with various classes of mine, but Josh’s visit needed to be too brief to get him into a meeting with students.

Matt described his company, Logic Products, and explained how the breadth of Dordt’s Engineering major has served him well. He brought three show-and-tell examples of products he has worked on. For the sake of brevity in this blog, I’ll only describe one. Matt’s company does consulting engineering. He worked on a project with Honeywell to eliminate mercury from their classic “round thermostat” product. (Some interesting history on the original industrial design for this thermostat–”Form Follows Function” ) Mercury is a heavy metal that can pollute the environment when the thermostats are disposed of at the end of their life. The new design retains the look and feel of the product but is all electronic inside. The look and feel is the same for builders and installers too. The connections are the same, the mounting holes are the same, and there is even a provision to level the thermostat on the wall, just like on the older design. Matt described how he was able to apply the courses he took here at Dordt college, including EGR 304, Microprocessor Interfaceing, a course I teach.

Josh discussed his work at Fagen Engineering in Granite Falls MN where he is Vice President of Engineering Operations. His company also does consulting engineering. They design ethanol plants. We discussed our views of the future of the ethanol industry, especially looking toward what might compete with the industry in the future, such as gasification of other substances besides corn, e.g. switchgrass, to produce a variety of liquid fuels such as gasoline (rather than ethanol) and plastics. Professor’s Brue and Timmer both have done research in the area of gasification or fluidized bed heat transfer–a process that can be used in gasification.

Brandon just finished his master’s degree in electrical engineering this past December and he is heading on to a job with Cisco Systems this summer. He was able to meet with our EGR 204 class. He discussed the challenges he faced in the transition to graduate school. On our campus most discussions assume Christianity is a good thing. Challenging questions might be something like, “can a homosexual be a Christian?” (Homosexuality is a topic on campus right now because Soulforce has decided to visit our campus in an attempt to promote acceptance of GLBT lifestyles.) In contrast, in a state university setting he was challenged with questions like, “How can you be a Scientist and a Christian at the same time?” (Christianity is seen as irrational. If you are irrational, how can you be scientific?) Brandon mentioned that classes, Bible studies and other meetings at Dordt helped him articulate his views effectively to the skeptics around him. He made an analogy between an engineering education and a car. In this analogy the technical subjects give you the horsepower to move your design forward. The perspective he gained at Dordt is like the steering system and suspension of the car. They determine how well your can direct your horsepower to navigate the bumps and turns in the road. Without a good suspension and steering system, horsepower is useless. He discussed how impressively the Christian perspectives he learned in depth at Dordt have served him in graduate school and in interviewing for jobs, and how often people seemed to resonate with these perspectives when he had time to explain them.

These are the kind of reports back from our graduates that fire me up to do my best. These meetings (and many others!) have made this a busy week–this is my first blog entry since last Friday–but the busy schedule is worth it.

Y2K Redux

Remember when we were all told that we needed to patch our computer’s operating systems and our programs and make sure we had printed bank statements and all that because when the date changed from 1999 to 2000 we were going to have trouble? Well, we have done something like it again. Congress has changed the dates on which daylight savings time starts and stops. Again the news is that we better be up-to-date on all our patches etc. I find it interesting. I’m concluding that there are some limits to the amount of detail that we should computerize. Here’s another example. I had a friend’s telephone number on a speed-dial button on my telephone. It was a long-distance call and I had programmed in my calling card number (remember those?) the 1 and area code– the whole thing. I thought it was really neat. All I had to do was press one button and the speed dialer would do the work of pressing about 30 keystrokes, even pausing at the right times to enter my PIN number and so forth. Then one day I got a new phone. I had not written down his phone number. That old telephone with the speed dialer had no display so I could not recover the number from that phone. Then I realized that my reliance on the speed dialer had a limitation. Now I find these things happening over and over. Got a new computer? Want your e-mail address book transferred? That might be work! How about your itunes and photos? All those gigabytes will need to be moved too. Maybe a stack of CD’s would be more durable in the long run. But maybe not. Right now I have no answers, but I think the question of how much detail to store, like when daylight savings time starts and stops, is an interesting one.

Engineering —> Leadership

The American Institute of Physics reports that engineers do better than biologists on the MCAT for admission to medical school. (Thank you Professor Brue for mentioning this information to me.) Here’s the rank:

1st place: Biomedical Engineering majors
2nd: Physics
3rd: Electrical Engineering

Biology majors came in at 11th place. (complete report)

Does that surprise you? There is a stereotype that engineers are narrowly interested in things and not people. According to that stereotype, the engineering lifestyle revolves around stuff like compressors, circuit boards, core samples, and pimped out computers with dual monitors. Engineers supposedly eat lots of donuts, pizza, donuts, Big Mac’s, donuts, pizza and for some variety, Whopper Burgers. They slurp Mountain Dew Code Red by the 2-liter bottle till about 4 AM each morning to get a pile of tediously detailed engineering work done during hours when nobody is awake to interrupt them. By 6 AM they are refreshed from a nap on the couch in the company’s front lobby. They can’t wait to get back to work. They talk incessantly using arcane initialisms like “PLC” and “FPGA” and “DMA” and “QPSK” or better yet, “differential QPSK,” so you can’t understand what they’re talking about. They think they’re smart. (Maybe I’m having too much fun writing this stereotype!)

Well, it ain’t true—at least not the bad parts of that description! These results on the MCAT are just more evidence that engineers have a life. Engineers, even electrical engineers, are very interested in and capable of understanding broader issues such as, in this case, healthcare. And there’s a magazine article to the effect that more CEO’s have engineering degrees than business administration degrees as their first degree! A good engineering education is a ticket to leadership. A Dordt engineering degree has already lead to leadership roles (VP of engineering, company owner, company founder, university professor, etc.) for several of our graduates.

Most importantly, I’m glad to be at Dordt because, although many engineering schools know about the leadership connection to engineering, it can be an accidental side effect. Dordt has an engineering program that roots its concept of leadership in the the Bible. We call it servant-leadership. We see Jesus as an example of leadership. We do our studies and set our priorities (as best we humbly can in our sinful condition) in order to serve the Lord. What could be more motivating, provide a better sense of direction for our work, and build a better community? And the leadership of our graduates is sought after. Plenty of companies aggressively recruit our graduates and hire our students as interns.

Award Winning Senior Projects

Friday I mentioned the senior project I’m advising this year. (See “A Clock Tower for Dordt?” below.) Last year I advised a project by Alex Haas and Chad Talsma on a brushless DC motor. That project won a “Merit Award” from the James F. Lincoln Arc Welding Foundation. (The 2006 awards are not yet posted on their web pages as I write this, but eventually they will be posted.) This project was sponsored by Groschopp here in Sioux Center.

Another project, the Flat Stacker, done by Dave Kielstra, Andrew Kroeze, Greg Mac Leod and Jon Vander Vliet, and advised by Professor Dressler won a Bronze Award in the same contest. This project was sponsored by Sakuma Brothers in Washington State. You can read an overview of these projects here.

Update (added 5/1/2007):
The Lincoln Arc Welding Foundation Awards for 2006 are now posted on the web.
The Flat Stacker project is mentioned on the cover page and on page 5 (as paginated by the Adobe Reader) or page 32 (as printed on the page). The Brushless DC Motor project is mentioned on page 6 (Adobe Reader) or page 33 (printed), second column, third project down.

A Clock Tower for Dordt?

I advise a team of engineering students (Ashley , Chris , and Craig) who are working on the design of a clock tower for their senior project. They just started their own blog on the topic. There is not much on the blog yet, so I’ve posted a comment to see if we can get some discussion started. You can see their blog and my comment at http://www.dcclocktower.blogspot.com/. My comment is under their blog entry titled “The beginning of Time.” There is also a Facebook group called “Say Yes to a Dordt College Clock Tower.”

Matt Hilden, Class of 2002 to Visit

In Monday’s post I mentioned that I was planning an IEEE student branch meeting. Now it is set up. Our guest will be Matt Hilden, from our class of 2002. The meeting will be at 2 PM on Monday, February 19, in room S216. Matt works for a company called “Logic Products” in Minneapolis. He will speak about his years at Dordt, the transition from school to work, and the type of work he does. I’m looking forward to this meeting.

Logic Design in EGR 204 Micro & Digital Lab

It has been a rather routine day. That’s good–it means I get to work on my agenda! I’m working on setting up a possible IEEE student branch meeting for later this month, but I don’t have enough information to get specific yet. This afternoon in the EGR 204 Microprocessors and Digital Logic Lab the students worked on simulating a digital circuit that incorporates hierachy. We use Altera’s Quartus II software for that. Next week my EGR 204 students will start their first design project.

Interesting IEEE meeting coming up

I’m a member of the IEEE and have been active in the activities of the Siouxland section of the IEEE. On Thursday, February 15 they will be putting on a good meeting on the topic of open soucrce software used to aid the design of electronic circuits. You can read all the detials in their February newsletter which just came out today. I’ll be planning to attend!

Coaching JETS/TEAMS at Unity

On five January and February Thursday mornings and some Friday afternoons I coach Unity Christian High School’s team for the “Junior Engineering Technical Society’s TEAMS” contest. The morning practice meets start at 7:10 AM, which shows some dedication on the part of these students! Sixteen Unity students in two teams of eight will compete on February 21 in this national contest. We’ve done OK in past years. Last year Unity’s junior varsity team placed 16th in its division nationally. Today we had very cold weather so I selected a practice problem on the wind chill factor. You can try it out yourself if you like. Some of our team members got about eight of the ten problems in the 50 minute practice meet. That’s really spectacular performance. Even scoring 60% on this test virtually assures that the team will advance to the national competition.

I should also mention that in past years Professor Van Gaalen has partnered with me in coaching this team. He’s on leave this semester. I hope I can fill his shoes and keep the winning record going!
