Why I Became an Engineer
Why did you become an engineer?(06/24/07, 11:37:00 PM EDT)
–>Some years ago my son was tasked with a high school assignment to build a circuit to re-encode a bank of switches. The teacher expected a simple diode-based design, but I suggested tossing an embedded computer in, so if the problem changed the solution would be trivial.
Also, of course, the thought of tweaking the instructor was appealing. When Graham got the thing working, the flash of excitement in his eye was a tremendous reward. He built the project, he wrote a little code. And it worked.
That’s exactly why I became an engineer.
Engineering is the art of solving problems. "In order to make a machine that does X, I have to figure out how to design some hardware and firmware that does Y." Puzzling out these solutions is both an intellectual challenge and a game. Am I smart enough to do this? What will I have to invent?
Problem solving is its own reward. But it’s not enough, for me at least. I want to make something that works. Not push paper, not write proposals, not document someone else’s creation, though all of those tasks are an inescapable and wearisome part of this profession.
But I want the thrill of seeing the motor turn, the LEDs blink, or a message marqueeing across the display. No doubt that "I made that work" satisfaction is rooted somewhere in the same brain center that rewards gamblers and addicts.
A lot of developers work on large projects that take years of effort. More power to them, but I could never do that. I want to see something work, relatively soon. Invent solutions, see them implemented, and move on to the next project. You can have those big government projects that consume entire careers; the thought of being caught in that mill horrifies me. Thankfully others are more patient and will see these efforts through.
I sort of fell into the embedded space as it didn’t exist in the late 60s when I was in high school. An obsessive interest in electronics morphed into ham radio, but the important thing to me was always building something. First, learn the material, absolutely. But do start with just an infancy of knowledge and build a small project to get feedback, for fun, and to get a visceral learning that does not come from books.
Later I learned about programming (rather, became consumed with it), and when the first microprocessors came out was accidentally and fortuitously positioned with the right skills and interests.
To me, embedded is the best of all engineering fields. One person can design circuits. Write code. Often figure out the science, or at least its application. And then make something that works.
In the olden days some companies didn’t let engineers work on the hardware. Technicians soldered, scoped and instrumented under the direction of an engineer. Screw that – half the fun is working with the hardware!
The irony now is that hardware can be so hard to manipulate – I have a sub-inch-square chip on my desk with 1500 balls on it – that the required special equipment becomes a barrier to that intimate physical manipulation of a circuit that can be so satisfying. If that sounds like some sort of foreplay, well, perhaps there is a connection between those two parts of the brain, too.
What about you? Why did you become an engineer?
I am an engineer. And I love what I do. My Dad was an Electronics Engineer, and I saw first hand how much fun it was, while growing up. So, I followed in his footsteps and became an Electronics Engineer myself. You come up with an idea, you design something, implement it, and then it works! Problem solving is, indeed, its own reward. And then your stuff works! I just can’t describe this feeling. I guess, only a fellow engineer can understand why I get excited over some waveform on the screen of an oscilloscope. So, I have fun all day playing with things and get paid for it! What can be better?
