Black technology: I can decompose everything

Chapter 20

After listening to his words, he was prepared in his heart. He didn't plan to get Zhou Meiqin's answer right now, so the next step was the same as before, and he lay down on the sofa to rest.

In the afternoon, as usual, I sat in my class and studied hard, but in fact?He didn't know where his thoughts had gone.

Don't look at him reading with a book in his hand, but his attention is not on the book, his thinking is designing the electric car controller in his mind at the moment.

It is impossible for him to draw design drawings in real life now. He can’t just draw design drawings while others are learning. It will attract the attention of others, and he will not be able to answer when others ask.

But it's okay to imagine it in your own mind first. Since he has fully mastered the knowledge of junior high school and integrated all the relevant knowledge, his brain or IQ has changed a lot compared to before.

He also made some guesses. On the one hand, he was enriched by knowledge, and on the other hand, his brain was largely developed.

This allows him to complete this design in his mind. Although he doesn't know any chips that can be used, even if there is no chip, he can use all diodes, triodes and other things to design a controller that can be used for electric vehicles. design drawing.

Although the controller made with this design will be bulky and bulky when it is actually made, it is also good to make a preset in advance.

When the conditions are ripe in the future, after finding a suitable and usable single-chip microcomputer, it is not difficult to replace part of the circuit with a single-chip microcomputer.

Perhaps in the eyes of others, this method is clumsy, but it is the most suitable for his situation now.

The controller of an electric vehicle is like a trip computer used in a car, but it is not that complicated and has a single function. With his current knowledge, it is easy to design such a controller.

What is the role of which diode, which resistor is responsible for whether the current on which circuit should flow back, all these are slowly taking shape in his mind.

When he designed this controller, he still had an idea one second, but felt inappropriate the next second, and he would make changes according to the problems that occurred.

Although he is drawing very slowly, it is not without progress. At least he has completed a very basic version now. If it is done according to this in reality, it will look bloated, but at least it fully meets the functions that the controller should have.

When the last class in the afternoon was over, Sun Xin next to him was ready to rush to the cafeteria. Those who came to the cafeteria first had the right to choose the cuisine, and they could scoop up egg drops for free egg drop soup.

But he is still immersed in his mind and can't extricate himself. At this moment, he is trying to simplify the structure of the designed controller, trying to achieve the design goal in another simple way.

At this time, he was ready to go out to Sun Xin when the bell rang, and looked at him who hadn't moved much. When the teacher wasn't paying attention, he elbowed him.

Immediately, he also turned around, looked at the time and packed it up very familiarly.

But when the bell rang and the teacher who had finished the homework on the podium was about to walk out of the classroom door, their head teacher appeared at the door of the classroom.

He and Sun Xin's idea of ​​sprinting [-] meters fell through, and sat down honestly in their seats, like obedient students.

"Li Zhenhua and I come here, and the rest of the class is over!" The head teacher who appeared at the door knew the students in the class very well, so he just called him and then left quickly.

When he was called, he quickly got up and followed. He didn't know what would happen next, but it must have something to do with what he told his mother at noon.

After he walked out of the classroom, the class immediately became lively. The students were rushing towards the cafeteria at a speed of sprinting [-] meters.

The bustle behind him has nothing to do with him, he has come to the teacher's office now and sat down on the stool opposite the head teacher.

To say that he was afraid to sit down before, but now he will find a stool to sit down no matter what the teacher says. This is completely different in mentality.

"In the afternoon, your mother called me and said that you don't want to go to evening self-study for the rest of the time. Tell me what you think!"

Facing him who was sitting opposite, the teacher just twitched the corner of his mouth but didn't say anything, but went straight to the point.

"Teacher, I have already mastered all the knowledge required for the exam. You should be able to know it after passing the previous month and the three exams just passed.

For me, it doesn't make much sense whether I continue to stay in school or not. First of all, it's not my arrogance! "

He spoke confidently to the teacher in charge, as if he was stating the facts.

And what he said, combined with reality, the head teacher also nodded in agreement, obviously agreeing with his statement.

"I understand what you want to express. As for your idea of ​​not being able to go to evening self-study, I don't agree but I don't object. I make up my own mind. But I'm a little curious. Can you answer this doubt in my mind?"

Hearing the sentence of disapproval or disapproval, although he had expected it, he couldn't help being agitated. After finally calming down, he said to the head teacher: "Please tell me!"

"Since you can improve your academic performance to a level that others can't match in a month, why didn't you show it in the previous three years?"

Regarding the teacher's question, he never thought of it, even if he had any guess what the head teacher would ask, then he was silent for a while, thinking of a prevarication reason before answering.

"It's just that I didn't focus on my studies before. Isn't it something I should have at my age now? Of course, I did it to save trouble, and I don't want to attract too much attention, hehehe..."

Hearing his answer, the head teacher also understood his thoughts, but he always felt that something was wrong, but he didn't want to understand what was wrong.

"You kid... you're a bit cunning! Go back and tidy up before you go home!" The head teacher said to him with a smile and a little teasing.

Standing up, he raised his right hand and stretched out two fingers, made a very American two-finger salute, and walked out of the office lazily.

After he left, the head teacher was left alone to reflect on it, and after his figure completely disappeared before his eyes, the head teacher finally figured out what was wrong.

His performance is too mature, he knows what he wants, and he is very purposeful, and when facing himself, he does not have the embarrassment of a high school student at all.

In other words, he is facing his teacher with a very equal attitude, just like the communication between ordinary people, mature.

After Li Zhenhua left the office, he happily walked towards the classroom.
