Dr. Dave from Goz7.com was nice enough to drop me a note recently. He is also in the field of analog electronics, but much more experienced and has written some really solid technical articles (such as this recent one about low noise discrete amplifiers).

He also mentioned that a friend of his (Bruce Gammill, no relation) was the chairman of a group dedicated to promoting Colorado’s tech region. While I’m not here to say whether the area is the next silicon valley or anything, I do appreciate the fact that it is another resource available for electrical engineers. Specifically, the “beta” section of the site shows a wonderful map of all the companies that are located on the 40 mile corridor from Denver to Fort Collins.

I love StumbleUpon. If you don’t know, it’s a site that gives you random sites to visit at the click of a button. It’s been around for a while now and it will ruin your afternoon or evening if you’re not careful. It’s also sent more than one visitor to this site before and hopefully exposed them to some analog engineering topics.

Anyway, I’m also a user of SU and have noticed a trend on the “Electrical Eng” side of things:

We all have to start somewhere.

I’ve been thinking about my posts as of late. Moreso, how I can offer something of substance to readers. At least substance that is usable on a daily basis. What do EEs want to read when they get to this site?

I came up with part reviews. I started something similar at my other project, Electricio.us. Spec sheet analysis is a critical skill for any analog engineer. It’s also is time consuming and hard to keep up with. So why not have a few choice parts highlighted on here? I don’t plan on reviewing the newest and hottest parts…but maybe the most useful. So let’s start with the LM741.

I was recently talking to my girlfriend about if we ever moved and needed to find jobs, where the most likely place would be to find work as an electrical engineer. It was interesting talking out cities that may or may not sync up with places she could find a job. Now, I don’t have much interest in leaving my current job, and while I hope to work on my own some day, I’m still quite dependent on employers for my livelihood.  So I did the fast/easy thing and went to Indeed.com and checked available positions under “electrical engineer”. Simple enough. So where are the technical jobs these days? (obviously this data is meant to change over time)

I was reading about the latest WordPress 3.0 release, yet another step forward in open source software. I was eager to try it, so I updated last night. But the more interesting thing in the midst of my reading was a program also by the folks that make WordPress; more specifically, I was reading a sarcastic essay written by Matt Mullenweg, creator of WordPress. He was writing about how comment systems were in serious need of an update and was pushing for the comment system implemented in IntenseDebate. So I gave it a shot, and that’s what’s running the comments now.

I recently had the opportunity to ask some questions to Mike Demler, electronics analyst and writer at The World Is Analog. He has many years of industry experience, culminating by recently joining DIGDIA**, a strategic consulting service that helps with market analysis and business planning. Let’s see what he had to say:

Chris Gammell: Can you please explain your background?

Mike Demler: Explaining it may not be that easy, but I’ll give it a try.

This is part 3 of 4 in a series about ESC Chicago and the Sensors Expo and Conference. See previous posts about Day 1 and Day 2.

I imagine if a doctor was diagnosing the medical condition of the embedded community, he would walk into the tiny exam room, take one look at the embedded community sitting there in its socks and underwear on the crinkly disposable exam table cover and say:

Wow.

What a whirlwind day. I started at 7:30 am and I ended at 10:30 pm, my mind still reeling. I was talking Beagle Boards and Agile processes in the morning and discussing the media (with the media) and visiting hackerspaces in the evening. But the best part about it? I felt like there were a lot of people around me that cared about similar stuff to what I do.

I am lucky enough to work with some of these people as well. But the nerd population in Cleveland isn’t at the critical mass that occurs at conferences nor at hackerspaces. So yesterday was a great opportunity to converse on some of the topics I love with people who were interested to hear it (in person of course, I realize there are many great people who “listen” to me on this site…thanks!).

The first day of the sensors and ESC conference is meant to be a symposium…think college lecture, but for 8 hours. It was an interesting first view of not only the presenters, but also the audience; the ones who cared enough to pay and attend for all 3 days (going to see only the “expo” for the next two days is free). These same lucky people will get to attend breakout sessions for the remaining days.

I recently found out that I’ll be attending the Embedded Systems Conference in Chicago early next week. I also will be attending some of the events at Sensors Expo & Conference, which is being held in the same conference center. I couldn’t be happier that I get to attend two conferences in one shot AND that I get to visit Chicago in the process.

So why embedded systems? “I thought this was a site about analog electronics,” you say. Well, it is. But good luck making an all-analog system these days. These days, analog is more about signal conditioning, power, control and accuracy. I mean, everything is analog in the end. Even digital signals will look analog if you clock them fast enough; but the point is, digital is an important topic to know as well. Embedded systems let you interface to the fun analog systems at a lower level (think running code in C instead of a full blown implementation of Windows) so you can run your systems even faster, cheaper and using less power.
