How to quickly learn electronics?

 How to quickly learn electronics !? "Isn't the author crazy?" - you will think. Someone can learn to program microcontrollers in a couple of years, while someone will still collect tweeters and flashlights. This already depends, of course, on the person himself. But let's get back to the question ... Is it really possible to quickly learn to understand circuits, collect electronic trinkets on them and learn how to program microcontrollers? By the way, there is an interesting article on this at https://diystadium.com

So, let's start from afar ... Once upon a time there was one Italian. His name was Wilfredo Pareto. And he was very observant, he loved to watch everything. Somehow he watched everything and everything and understood one important thing in the entire Universe. And this thing sounds something like this:  20% of the efforts give 80% of the result, and the remaining 80% only 20% of the result . Hmm, sounds good, but is it? And is this law observed in our entire universe? Let's check it out! Here are some statistics:

• 20 percent of countries with less than 20 percent of the world's population consume 70 percent of the world's energy reserves, 75 percent of metal and 85 percent of timber.

• Less than 20 percent of the total land area provides 80 percent of all mineral resources.

• Less than 20 percent of wars cause more than 80 percent of human losses.

• Wherever you live, 20 percent of clouds produce 80 percent of rain.

• Less than 20 percent of recorded music is played over 80 percent of the time.

• In most art museums, 20 percent of the treasures are on display 80 percent of the time.

• Less than 20 percent of inventions have more than 80 percent impact on our lives. In the twentieth century, nuclear power and computers were more influential than perhaps hundreds of thousands of other inventions and new technologies.

• 20 percent of the land provides over 80 percent of food.

• 20 percent of articles of "Practical Electronics" are viewed by 80 percent of readers :-).

In fact, the entire life cycle, from an acorn to a giant oak, from a small grain to vast fields of wheat, is a reflection of the 80/20 principle , taken at its largest. Minor reasons - colossal results. This principle was soon named 80/20, or the Pareto principle , after the observant Italian.

To learn electronics, I went to a radio club, read books on electronics, graduated from a university with a degree in radio engineering, but about myself I can't say that I'm a super-duper electronics engineer ... Five years of university is a solid theory that nobody fucking needs. Why did you have to memorize all these three-level formulas and theorems? After graduation, they all the same weathered, like dandelion seeds in a light breeze, but still I am grateful to the university for the fact that there I was taught to quickly understand the material and think quickly.

Somewhere by chance, on the pages of the Runet, I read about the Pareto principle and thought to myself: “Where are these 20% buried in the study of electronics?” After analyzing the time during which I studied this area, I understood everything as follows: 20% is

- sitting in the evenings with a soldering iron and soldering circuits

- radio forums and sites without copy-paste from textbooks and encyclopedias

- communication with the same teapots in electronics

- practice, practice and more PRACTICE!

Oh, and how many books on electronics are now on the Runet ... “Radio electronics for dummies”, “Entertaining electronics”, “Electronics from A to Z”.

How many I just did not read them. Yes, I agree, there are good books, but mostly books on electronics were written by some professor with five-story formulas and logarithmic graphs. Reading books on electronics? I think this is not for everybody. Again, the 80/20 principle suggests itself. 20% of books provide 80% of knowledge. But these books still need to be found. On my own I will add, do not waste your time if the book on electronics does not suit you in any way. Start reading another one. Still, I tend to lean more towards the practical part of electronics. In practice, electronics belongs to that 20%. Are you still sitting? Now run the soldering iron into your hands!
