I like it when I understand things. The universe feels like a little safer place, even if I realize feeling secure is only a state of mind. And when I watched Steven Chu talk on the Daily Show the other night, I felt safer. Not like a warm security blanket kind of safe. More like a “Hey, if stuff hits the fan, we’ll probably be able to figure it out” kind of safe.

I had an interesting conversation today with a few friends about the exodus of young people from the workplace back to school during this recession. It seems as though people in Generation Y are bailing left and right on current jobs and diving back under the safe covers of academia. And who can blame them? You get to work on interesting research (hopefully), you get a stipend (maybe) and you have better prospects when you’re all done (eh, doubtful). But that leads me to ask, “Who’s going to do all the work when the economy is in full swing again?” Let’s survey the current demographics, starting from the top:

Irony is having a blog post in your queue with a title such as this one and just sitting on it for weeks on end. Luckily I’ve been trying some things instead of studying them, it just so happens that those things have nothing to do with this site. I hope to discuss those on this site soon.

I am a glutton for knowledge.  Part of it is my fear of looking silly in front of co-workers when I don’t know the answer to something. Part of it is feeling like my knowledge base is lacking and the thought that I can always learn or teach myself something new. But when presented with a new challenging situation that requires you to learn the question is always the same: where do you start? Do you jump in and try it out? Or sit back and study what others have tried so as to not duplicate their mistakes?

I find myself sitting around these days trying to catch up on knowledge I feel like I missed in school. Worse, I feel like I learned it at one time but it all fell out the other side once I took the exam. Pretty standard really, when you don’t think you’re going to need to the knowledge some day. Haven’t you ever sat in class wondering if you’d really ever use the material you were expected to learn? How much did you pay attention?

The Digital Switchover.

Not me. I almost did that a while back, but no. Not me.

Television.

Normally I wouldn’t write about it. A digital television standard is long overdue and in the end this will be a good thing. When you compare Analog vs Digital, there are many more benefits on the digital side of things: lower power for transmission, better bandwidth of signal, more bandwidth usage over the spectrum. All of these are good things. I can even talk about how those digital signals still have lots of analog components as they’re transmitted over the airwaves: multipath, signal loss, power calculation, reception problems, etc.

One of the best parts of working with others interested in electronics is having similar hobbies: namely, electronics and music.  And even though I have similar hobbies, I never really brought them up in conversation with co-workers (believe me, some of the stuff I have done pales in comparison to some of the people I work with). However, in the past few weeks it has really paid off talking about my non-work work, both for my personal hobbies and for things to write about that interest me.

If you are an engineer who regularly works with your hands, you likely troubleshoot on a daily basis. It’s just part of the job. Sure, you can say, “I never mess up!”, but hardly anyone will believe you. Because even when your best laid plans go perfectly, Murphy’s Law will soon kick in to balance things out. We learn to deal with these things and have developed tools and measurement equipment to help us diagnose and deal with these problems: Multimeters, Electrometers, SourceMeters, Oscilloscopes, Network Analyzers, Logic Analyzers, Spectrum Analyzers, Semiconductor Test equipment (ha, guess I know a little about that stuff)…the list goes on and on. But what has struck me lately has been that as parts on printed circuit boards get smaller and smaller, troubleshooting is getting…well….more troubling.

Analog. Digital. Continuous. Discrete. Choices abound.

Well, not really.

In reality you will deal with both kinds of signals when working on just about any electronics these days. A simple example is in a switching regulator. These devices are meant to take input power from a wall plug or something providing a relatively constant voltage and then the regulator will ensure that the voltage is always the same when leaving. Internal to the circuit, a “digital” signal (on or off) determines when to let in incoming power go from the input to the output. The “digital” signal translates into an “analog” voltage at the output, hopefully the voltage you programmed.

I am not a perfectionist. I think of myself as too practical to be a perfectionist.

However, I find myself setting very high expectations for myself and I don’t feel I am alone. Generation Y has always been encouraged by parents and others every step of the way. We have been told we can do anything and more drastically, we can do everything. We have been multitasking since kindergarten and over-scheduled ever since. We played the most little-league sports, we took the private music lessons, we had the private language tutors, we were boy scouts. We had the most extra-curriculars on our college applications, we had the best grades we could, we took all of the AP classes and we applied to more colleges than we’d ever need to. We took the most engineering credits, studied as many hours as we could stand, we drank during the remaining hours and we graduated with as many minors as they let us. We had the most interviews as our schedules would allow, we got the most job offers, we had the biggest signing bonuses and we got the fanciest job. We expect the biggest promotions at work, the biggest pay raises, the best benefit packages and the best of everything.

I am very excited to announce that the Wurlitzer 200 is fixed and operational. I say Wurlitzer 200 instead of 200A because a nice chap emailed me and let me know that I actually had an earlier model. Either way, it works and it sounds delicious.

Really this post is to gloat a little and to post the sound samples I recorded with my friend Joe. He is a great piano player and shows off the awesomeness of the Wurly better than I ever could. I also wanted to lay out some future posts about the Wurlitzer that I plan to write:
