Children will always have some very lofty ideals, children of the same age generally want to be scientists or teachers when they grow up, and some want to be policemen or doctors when they grow up, like Chen Mo, who basically wants to be a TV repairer when he grows up, I have to say, his ideas are indeed a little different.

At this moment, Chen Mo is holding a broken TV motherboard in his hand, this motherboard is the waste that Daddy Chen replaced when he repaired the TV, in Daddy Chen's opinion, this motherboard is no longer usable, but Chen Mo feels that this is not the case.

Although this motherboard has been used for a long time, most of the originals on it are good, and as long as the broken ones are replaced, it will continue to work.

Chen Mo held an old multimeter eliminated by Daddy Chen in his hand, and began to check which component of this motherboard was faulty one by one.

This is a very boring, but also very careful work, Chen Mo meticulously tested one by one, and it took more than a quarter of an hour for him to finally find the problem - it turned out that an electronic circuit on this motherboard was a little poorly contacted.

Chen Mo couldn't help but turn his head to look at the other TV motherboards stacked next to him, only to see him frowning and saying, "Why is there a problem with this original?" It can't always be such a coincidence, right? ”

After Chen Mo finished speaking, he took out a worn-out wall calendar from the corner, turned directly to the third page, and looked at it carefully.

If there are professional TV designers who see the content of the calendar, it is estimated that their jaws will drop, because this page presents a complete TV motherboard structure diagram, which is marked in great detail with the name of each electronic component on the motherboard, and even the functions undertaken by these electronic components are also annotated below!

This structural diagram is artificially drawn at a glance, if it is drawn by professionals against the design drawings, it is good to say, but Chen Mo obviously cannot have the opportunity to contact professional structural drawings, which he created independently according to the knowledge he has learned, a fifteen-year-old boy, can actually do this, how can those professionals be embarrassed?

Chen Mo stared at a part of this structural diagram carefully, and after about three minutes, he frowned and said something like this: "This structural diagram is a little unreasonable...... In particular, this area does not seem to have been designed with the dense range of electronic circuits in mind, so that as long as a little dust gets here, it is easy to cause poor contact or short circuit......"

For a long time, Chen Mo has regarded the designed TV motherboard as the most authoritative model, and now there is a problem with this authority, which makes Chen Mo feel a little contradictory.

He carefully analyzed his judgment again, and found that it was indeed the design of this TV motherboard that had a problem, Chen Mo had to accept the reality, and thought in his heart: Since the authority is wrong, or ...... Do I redesign a structure diagram myself?

When this thought rose from Chen Mo's heart, it grew irrepressibly.

Five minutes later, Chen Mo turned the next page of the wall calendar and began to write and draw on it. From time to time, he would stop and look at the main board of the TV that was sitting next to him, and after reading it, he would continue to write and draw.

Early the next morning, Chen Mo was woken up by his mother, he rubbed his sleepy eyes and got up, and after breakfast, he picked up his schoolbag and went out.

The early sun rose from the sky in the morning, bringing a touch of warmth to the earth, Chen Mo walked on the way to school with his head down, and while walking, he gestured with his hands to the air, looking like a nervous disease from a distance.

On the road, you can see students carrying schoolbags to school everywhere, most of these students walk together in groups of three or five, everyone talks and laughs, and from time to time they will make trouble, but Chen Mo walks alone and does not join any small groups.

The classmates also seemed to be used to Chen Mo walking alone, and seeing him with his head down and gesturing, no one thought it was ridiculous, because everyone was used to it.

I don't know when it began, Chen Mo gradually became estranged from his classmates, he seemed to prefer to stay alone, these classmates all had a kind of attitude towards him, and never took the initiative to disturb him, in the eyes of these people, Chen Mo belongs to the top students among the top students, and is a model of five good students in the eyes of the teacher, and it is estimated that only those top students and teachers can talk to him, right?

After entering the classroom, Chen Mo handed over his homework to the group leader, and then he sat in his seat and started to stay.

The desks and chairs in the classroom are all single-seated, and Chen Mo was arranged by the head teacher to the middle of the first row of the second group because of his good academic performance, which is the best position in the class, because it is the closest to the teacher, and the teacher's lecture can be heard very clearly.

After the morning self-study bell rang, the classmates took out their books and read them, Chen Mo also opened the math textbook and looked at it, but his eyes were fixed on the textbook for a long time, and the math textbook stayed on a fixed page since he opened it, obviously, he was in a daze again.

The students sitting next to each other seemed to be accustomed to Chen Mo's appearance, and even the head teacher didn't say anything when he walked into the classroom and saw Chen Mo like this.

It is said that students with good grades will enjoy certain privileges from the teacher, which is true, Chen Mo is in a blatant daze during class time, and he doesn't even care about the homeroom teacher, who can say that he is not?

Chen Mo was basically in a daze throughout the morning self-study, and when the morning self-study was over, Mr. Wang's voice woke him up, only to see Mr. Wang knock on the podium and say: "Ladies and gentlemen, the school is going to open a computer course today, have you brought your computer class fees?" ”

Computers are not a new thing in these years, and there are many Internet cafes in big cities, but for this small town near the sea, it is still relatively new. When Mr. Wang announced yesterday that he was going to open a computer course, the students were all looking at it, but Chen Mo didn't hear it because of his habitual daze, and when he heard the news at this moment, Chen Mo couldn't help but be stunned, and then said in his heart: The school wants to open a computer course? How did I not know?

At this time, the students who brought money have begun to pay money one by one, and the cost is a total of 20 yuan, which is not too much, and the students have a great interest in computers, so many people have brought money over.

Of course, some people whose family conditions are too poor have no money to pay, and Chen Mo, who has not heard the news, there are still nearly ten students in the entire class who did not participate in this course.

Chen Mo didn't care about this, his current interest was all in the design of the TV motherboard, and the computer had not been able to attract enough attention from him.

Chen Mo didn't pay the money, so he could only stay in the classroom during the third computer class in the morning, and saw other students happily lining up to go to the computer room, Chen Mo did not show envy.

After most of the students left the classroom, he took out a TV motherboard and wall calendar from his school bag, and began to work hard.
