I'll have to defend my bazaar, ask a specific question and don't interrupt with others, if you don't mind.

I'll come up with questions tomorrow. If you are willing, write down what you have done in the field of electronics.

I was ten years old, I already knew how the "Christmas tree, light it up!" And then the experiments with relays and capacitors began, one by one.

If you have any questions, I will answer them tomorrow.

Question for those who are awake: What is it and why is it needed?

The correct answer is tomorrow.
