In view of the preciousness of the black and white TV, Ji Chen has never touched it, so naturally he doesn't know much about it.

Fortunately, he knows the principle and structure of a color TV. If he tries to convert it, he should be able to draw a circuit diagram.

The bookstore does not have any books about TVs yet, so Ji Chen can only use his own knowledge of TVs in later generations to convert the principles of color TVs based on his own knowledge reserves, and try to draw the circuit diagram of black and white TVs.

He doesn't intend to produce black and white TVs, but if he's just drawing pictures, it's fun to watch.

Of course, the most important thing is that brother Song is super interested!

The attraction of the TV to him was unexpectedly strong. Even if Ji Yu said in advance that the drawing might not be successful, he kept saying: "It's okay, it's okay, we will study slowly, and there are still several years before the factory is built!"

He has actually considered the extent of building a factory to produce TV sets.

Although it was just a drawing for fun, Ji Yu was still very serious.For technicians, caution is an instinct, otherwise negligence is regarded as a habit, and it is easy to make mistakes when it comes to real work.So since it was just a game to coax Xiao Song, he still drew very carefully.

Because he doesn't know much about black and white TVs, and he doesn't know what level the current transistor technology has reached, Ji Ruan needs to draw pictures and check books at the same time. The research progress is very slow, and he only drew the circuit diagram of the regulated power supply in a few days.Because only the regulated power supply is constant.

Song Jining is not in a hurry, in fact he is enjoying the current situation.

Ji Yu told him a lot of knowledge that he thought was extremely tall.

For example, the principle of TV receiving antenna, the function of high-frequency tuner, what is the video amplifier circuit, and what is the sound channel.

Although he knew many principles, he couldn't draw the wiring diagram of the TV.Every day after school, the two of them would get together to do their homework. After finishing the homework, Ji Xun began to take out the draft line calculations and draw sketches, and Song Jining would look up reference books and answer Ji Xun's doubts.

So even though the progress was slow, Song Jining didn't feel impatient at all when he thought that he was designing a luxurious and expensive TV.

In order to increase his knowledge, he spent all the money he earned from repairing radios to buy reference books on mechanics and electronics.

What is this small amount of money? If you can produce TV sets, you will earn more in the future!

Ji Yong and other friends found out that Ji Yu and Song Jining are very close recently, almost sticking together every day.

Of course, they used to be together every day, because Ji Chen wanted to learn how to fight with Song Jining!

But now the time spent together has reached an exaggerated level. Every day after school, Song Jining rides his bicycle to the gate of the primary school to pick up Ji Rafter, and then the two leave together.Ji Yong and others once thought they had some little secret, and secretly followed them.As a result, they were directly traced to Song Jining's house.

Everyone followed through the door, and saw Song Jining and Ji Yu quickly spread out their textbooks and began to write home!Court! Do!Industry!

Ji Yong's eyes widened.Not to mention Ji Yu, is Song Jining such a person?

Has Song Jining, who he has known for more than ten years, ever been so diligent and studious?

"The sun must be rising from the west today."

"Maybe where do they plan to go after finishing their homework?" A little friend guessed.

"Ah, maybe so."

If they plan to play far away, they will occasionally finish their homework ahead of time to avoid lack of energy when they come back.The friends guessed like this, so they simply took out their textbooks and moved aside, waiting to see where the two of them planned to go.

Song Jining and Ji Zhuan quickly finished their homework, quickly put away the textbooks and cleaned up the desktop.

The friends also packed up their textbooks and carried their schoolbags.

Seeing Song Jining turn around and go back to the room, he took out a big cardboard box, and the two of them took out a pile of draft paper from the cardboard box, and started to write and draw.

Ji Yong took one and looked at it. It was full of complicated lines and he couldn't understand: "Yuanyuan, Xiao Song, what are you drawing?"

Song Jining smiled mysteriously: "Secret."

Seeing how they were preparing to go out, he asked, "Are you going back? Go slow, see you tomorrow."

Friends: "..."

Ji Yong turned to Ji Yu: "Yuanyuan, don't you guys go out to play?"

Ji Yu looked at him suspiciously, and replied: "No, Brother Yong, go play by yourself, and tell my dad about me, I will go home later today."

The friends really want to know what these two people are doing, but they can't understand the blueprints they drew, and they don't know the accessories they can't get out. As for what devices, waves, and signals these two people are talking about together , I can't understand it at all! (╯‵ ′)╯︵┴─┴

When I came to Song Jining's house last semester, we could chat about picture books, homework and so on.

Why can't they understand what they are talking about after only a few months?

Song Jining and Ji Yu were very involved in the discussion. They have now researched the high-frequency tuner. Although they have no actual components, they feel that the current direction should be correct based on the data and circuit diagrams written by the two of them. So today I plan to formally draw it out.

So they discussed while drawing, until the smell of vegetables smelled, the two of them realized that it was already dark outside, Ji Yong and the others didn't know when they left, and they didn't know when Huang Yan came back, they had already fried the dishes and brought them out: "Okay, Let's discuss after eating!"

She didn't know what her son was doing, she couldn't understand those pictures, and the formula was like a bible, but she just thought it was very powerful.

Under Ji Zhuan's teaching, her son became more and more powerful, so powerful that she was already literate, but she still couldn't understand what his son wrote.

Listening to my son talking about what kind of research he is doing... He actually said research, which sounds amazing, just like the scientists on TV.

Huang Yan had little knowledge, and thought that "research" required wearing a white coat and holding chemical reagents, so she didn't take Song Jining's words seriously.Fortunately, she has always supported her son, as long as she doesn't fight, she can do anything, and it doesn't stop him from scribbling on paper every day.

Ji Yu rubbed his eyes, yawned, and sat down on the dining table obediently.

He didn't plan to spend too much energy researching black-and-white TVs. When the technology advances and color picture tubes are on the market, it will be more convenient for him to directly manufacture color TVs.He is not good at black and white TV, but he knows more about color TV. It is much easier to study than black and white TV, and it also makes a lot of money.

So in fact, it is to teach Xiao Song these principles and knowledge, and then draw a little every day.

That was the plan.

As a result, Xiao Song was too involved, and Ji Yu unknowingly followed suit.

According to the current progress, it may be possible to draw a complete circuit manufacturing diagram in a few months.

In addition to drawing blueprints, the two did not stop repairing on weekends, after all, this job is very profitable.

So the friends are even more unhappy.

"So, where are you two sneaking off to? Why didn't you call us?"

On Sunday morning, Ji Zhuan and Song Jining were pushing a small wooden box to go to the city to take a part-time job as usual, but they were stopped by Ji Yong and others who suddenly appeared and questioned them aggressively.

"Here, look at this." Song Jining held up the sign on the wooden box: "We are doing business, not playing, so we don't call you."

"Repair the TV?" Everyone was shocked.

"I can't tell you exactly, come with me!"

A group of people arrived in the city together by car, Song Jining told them to back away, and the two of them pushed the small wooden box and started to walk through the streets, shouting: "Repair the TV!"

Because the repair fee of the two of them is cheaper than the repair department of a department store, and they can repair everything, except for electrical appliances. Occasionally, the family needs to repair pots and pots. very.Not long after they yelled, someone stopped them and asked them to enter the house for repairs.

The friends were stunned for a while, and when Song Jining came out, they hurried up to him and asked him, "Xiao Song, do you really know how to fix TVs?"

"Did you go in and fix the TV?"

Song Jining hissed, and whispered: "The TV is just a gimmick, we mainly repair electric fans and radios."

"Xiao Song, when will you fix the radio?" Ji Yong asked in surprise.

Radio is also a luxury in their eyes, not much different from television.

Ji Yu said: "It's very easy, I mean, if you want to learn how to repair electric fans, I can teach you?"

"Why learn this, the electric fan is broken, just send it to the maintenance department." Someone said.

Song Jining hummed and raised his neck: "Do you know how much I can earn every day learning this repair?"

He reported a number, which immediately aroused the exclamation of his friends.Apparently no idea that a repair job that doesn't look like much can make so much money.

With the temptation of money, everyone became excited, and gathered at his house again that night, where Ji Zhen taught everyone how to repair electric fans.

Radios and watches are precision instruments, and we don't expect them to be able to learn them yet. Electric fans are much easier.

It's a pity that not everyone has the talent of Song Jining. They have never seen a miniature radio, are not tempted by high technology, and are really not interested in basic electrical knowledge. Two or three people quit immediately.After studying for a few more days, more people quit.

Don't look at Ji Yu's usual limpness. When it comes to various technical knowledge, he is even more fierce than their dean. They are not allowed to be perfunctory or casual, but they are even asked to draw the circuit diagram of the electric fan. If they draw casually, they will be punished. scold.

"Xiao Song, were you ever scolded when you were studying?" Ji Yong quietly asked Song Jining.

Song Jining nodded: "Of course, you can't stand it after just drawing one picture? When I first started learning, I drew more than one picture."

But he learned quickly, and he learned it completely after drawing a few circuit diagrams.

In the end, as Ji Zhuan and Song Jining expected, the group of little friends all quit.Although they are envious of the money Song Jining makes, such a technical job is too hard for them, and it is not worth the effort.

Song Jining was helpless: "That's why I didn't call you..."

It's not that they don't want to make money with their friends, but it's a pity that they know the characters of this group of friends too well, so it's okay to let them do other things, such as reading complicated reference books and drawing various circuit diagrams, how can they sit still.Or we can only wait for the factory to be built in the future and then pull friends.

Ji Yong looked at Song Jining, who was obviously still the same age, why did he suddenly feel that Song Jining was much more mature and stable than them?

"Speaking of which, Xiao Song, why did you suddenly fall in love with these technologies? Don't you think these books and pictures are very boring?"

Song Jining was in a daze: "Huh? Is it boring?"

Every book he reads is very interesting, but he regrets that he can't learn it, and he never finds it boring.

"Uh...probably because...I think these technologies can make money?"

Ji Yong waved his hand: "No, no, even if I gave you money before, it was absolutely impossible for you to read books."

Was he like this before?

Song Jining was stunned.He is now used to going home to do his homework immediately after school every day, and then studying the circuit diagram of the TV with Ji Chen, and after Ji Zhen comes home in the evening, he has to read reference books for a while before taking a rest.

Before he knew it, his bedside was already piled up with various reference books.

As for the distaste for reading in the past, it seems that I really hated it at that time, but I can't think of the reason for it.

Apart from the fact that his father is a scholar.
