Electronics for everyone 02/2016

Description

Editor-in-chief recommends

The February issue of EdW is bursting at the seams, and everything that we initially planned did not fit in anyway. We have a lot of topics in it, of which a great surprise for many of you is the matter of measuring the tiny resistances, in an "acoustic" way. After learning the first part of the article, you can "touch" yourself to this fascinating topic. I encourage you to act and share with us and other readers the results of your "low-risk" tests. The fact that this subject is really worth addressing is clearly illustrated by the article on cables on page 62. In this issue we have two new products for you. Finally, there was a place for a long-distance material in the waiting room with laser rangefinders. However, as part of familiarizing with the language of C and programming microprocessors, I invite everyone to visit a specific office, in which he works a poorly brainy, but very diligent and meticulous clerk. According to your opinions, next to the long-planned course C, we will present information for less advanced, so that they can also understand and like C language. We continue the Electronics course for junior (and senior). Already after the first episode it quickly turned out that this "electronic kindergarten" is very much needed. Take a look at page 10 to the Post Office and read the selected lists. I also encourage you to implement the presented experiments!
