Iwill never forget that day. I’m being sentimental, but it was a rainy Sunday afternoon of late January. I was around 11 years old, I was sitting at my desk, and, most of all, I was deeply bored. The light was fading from the only window in my room and the air was almost gloomy, save the pale circle of yellow light from the desk lamp. Sunday-blues-before-Monday-School.
What dark instinct drove me to grab that old radio-controlled toy car in my left hand, and that chewed screwdriver in the other, I don’t know. But my life has changed since. And in the same time, the life of many of my electronic belongings were to shorten.
A few cuts in my fingers later, I was holding my first DC motor. Next to me, the wreck of the toy car lied cracked-open on my desk, its plastic housing torn appart, and its inside wires and electronic boards spreading on the ground. And then the marvel happened; grabbing a 4.5V battery (the flat one I enjoyed so much to put my tongue on, a genuine scientific measure to test its life), I managed to join both wires to each pole of the battery, without any hope that anything would happen, really.
But then the motor made a sudden bounce and with a sharp sound the small shaft energetically spun at once. I was so startled that I dropped anything on my desk, disconnecting the motor from its power supply. Yes, I know that you can hear that faint music rising, the music of the great revelations (see below). It was now loudly resonating in my head; I tried the experiment again and again, and my mind was growing with expectations of gigantic and complex machineries I was about to build with this cutting-edge material and this new acquired knowledge. But first I had to inform my parents what a huge discovery I just made, and what a genius their son was.
Well, long story short, when I discovered the joy of electronics later at engineering school, it was a hard landing. But nevertheless, electric motors always stayed close to my heart.
Yes, controlling motors is difficult, it’s a deep jungle with savage inhabitants and weird names. But this jungle can be transformed into a kind of a public park, even a nice garden, with a little bit of work, of reading, and of jungle-clearing.
