Here is a small part of information that I have.
      I was born in a time when a "regular" computer occupied one room. Then good books were a rarity, good radios, TVs, voice recorders too. - At least in the country where I was born.
      To globally correct that situation - I could not do it, I was too young. But the situation in my personal space, perhaps, I could improve. I did just that - I had to create some devices myself. A good type of tape recorder, turntable, amplifier with speakers, home automation, etc. So I gained experience.
      The deficit of good books taught me how to handle technical information carefully and seriously. To satisfy the constant needs, I put together a good library. After reading several standards, I quickly delve into the essence of the issue and can offer a solution to help you.
