What are the sites for self-study of circuitry in Russian and English?

Question

Electronics

It will be better if these are sites that you yourself studied

Answer 1

There are a lot of blogs run by our comrades. You can get info there:
catethysis.ru
eax.me - articles on circuitry are often published here.
www.customelectronics.ru/blog is also a useful blog.
chipenable.ru - a wonderful site, I advise you to dig - there are circuit calculations and MK programming.
The DI HALT blog stands apart - there are a bunch of articles on MK programming, real-time OS and circuitry, of course. For example, this is easyelectronics.ru/osnovy-na-palcax-chast-4.html or this is easyelectronics.ru/upravlenie-moshhnoj-nagruzkoj-p...
In general, I recommend taking some ready-made circuit (soldering station / garland / whatever) and see which nodes are responsible for what and how everything works. In guitar gadgets, in general, there are some troubles, because. there are sometimes used unusual circuit solutions and there are specials. books on pedal circuitry (stompbox cookbook and others, look for Vkontakte groups if you are interested).
To make all this somehow structured, you can try to read the Fundamentals of Electronics I.P. Stallions. The Art of circuitry is also possible, but as for me, some important points are missed there, although the emphasis is on circuitry and not on the physics of processes in circuits.
A lot of channels on YouTube:
https://www.youtube.com/channel/UCFI31dsn8yxaarw6L...- detailed about electrical engineering and circuitry, I highly recommend viewing.
https://www.youtube.com/channel/UCuR4hQTXkG_KxozLx... tube amplifier circuitry in English.
In the future, if you have any questions, try to sit in telegram chats dedicated to embeded, where they will be able to answer your questions.

Answer 2

In such things, experience will give more insight than eye contact.
"It's better to do it once than see it 100 times."
Therefore, we take a small amount of money and blow on the ampere for the "matryoshka", or maybe something more advanced than the matryona is in trend now . I also had experience with this store . And may the toaster admins forgive me for advertising.
