MTL - Tech House System-Chapter 65 Electronic Interest Group
These seniors were the last time Wei Shuxun accompanied Sun Yi and the others to participate in the electronic design competition for college students. They saw Wei Shuxun carrying a toolbox alone, but could not see the person who accused Sun Yi. . Wei Shuxun has a good impression of them, and they naturally have a good impression of Wei Shuxun. These days, it has been rare to find a younger generation who is not pretentious or impetuous, and who is willing to bear hardships and stand hard work. Of course, the point is that young is not threatening.
This time, I mainly help the seniors of the foreign language department to set the stage. Although there was a performance on the New Year's Day party last semester, the girls in the foreign language department were not satisfied. This was their last semester at school, so they naturally wanted to be more lively, because the entire foreign language department decided to hold another theatrical evening party, and in the stage lighting scene, they found a few students majoring in electronics.
In fact, there are many people who can arrange stage lighting. As long as they say hello to foreign-language beauties, they can attract a large group of wolves. But obviously these seniors didn't want others to grab this opportunity, and they were too busy themselves. After thinking about it, they thought of the hard-working little brother last semester. Although the handsome face of the younger brother makes people uncomfortable, but he is young, only a freshman, and it is not threatening. Senior girls will not like this kind of younger brother.
Wei Shuxun didn't know the twists and turns. Several seniors asked him to help him make the stage, and they said they would teach him to make neon lights, and he naturally agreed immediately. Although neon lights are not very useful, they are barely a technology, and maybe one day they will be used.
The foreign language department also has its own people to set up the stage, and they mainly help to set up the lighting. Wei Shuxun followed behind a senior named Li Guonan, and his main job was to help him deliver tools and move ladders. Li Guonan taught him while doing it. It's not a very difficult technique, Wei Shuxun has a good foundation and can take over soon.
"Hi, Shuxun, do you want Coke?" A senior threw the Coke over, Wei Shuxun took it and waved: "Thanks!"
"Are you sitting firmly? Let me help you!" The senior smiled and looked at the handsome and handsome junior, and reached out to support the A-shaped ladder under him.
Wei Shuxun doesn't matter, he sits quite steadily on the seat himself, but he still said thank you, raised his head with the tool to adjust the rock light, and suddenly there was a loud cry from behind: "Wei Shuxun !" startled him. Turning his head, he saw Li Xiaoran approaching with anger on his face.
"Shu Xun, how can you do this." Li Xiaoran glanced at the senior, pouted angrily, and said to Wei Shuxun, "You asked us to tutor you. , it's only been a week, and I suddenly said that I would take a break, but I came here to play, what do you mean!"
Wei Shuxun jumped off the A-shaped ladder and was a little puzzled. He specially invited them to a meal before and told them to temporarily stop the evening tuition for a week, although Li Xiaoran was not very happy at the time, But he felt that he had made it very clear, and he didn't know what Li Xiaoran came to do.
"It hasn't arrived for a week, and the tutoring will resume next week. Sorry, if you find it troublesome, you don't need to help me." Tuition, all of a sudden don't. Wei Shuxun had nothing to do with this, he really felt tired and wanted to relax, he could only apologize to her.
"You... what do you mean!" Li Xiaoran stomped her feet, her eyes were red: "I'm kind enough to help you with tutoring, but I'll be disgusted by you!" After saying this, she suddenly ran out.
"..." Wei Shuxun really doesn't understand at all, what did he say wrong?
"Stupid!" Senior Sister pushed Wei Shuxun: "You still don't chase her!"
"Stop joking." Wei Shuxun climbed back onto the ladder: "I just loosened the screw, if I leave it behind now, be careful that you fall down when you dance."
For Wei Shuxun, who doesn't understand the style, of course, responsibility is more important. Although it is a trivial stage lighting arrangement, this is the work he promised to help, and he must be responsible to the end.
Actually, Wei Shuxun just didn't have a class to help, and he didn't need it at night. He just used this excuse to rest. Therefore, during the daytime class, I can still meet Li Xiaoran. There is no need for Li Xiaoran to run to find him. It feels too deliberate. But as a man, he can't be serious with a girl, and she has helped him. So Wei Shuxun asked Li Xiaoran why he was angry last night when he was in class the next day.
"I'm not angry, really." Li Xiaoran said with a smile: "I'm just worried about you, just remember to come back to tutor soon, your English foundation is very poor!"
I could see that she was really not angry, Wei Shuxun also smiled, turned his head and frowned. He found that he really didn't understand what the girl was thinking at all. His former friends, whether it was Chen Zixia or Zhang Ling, were all straightforward characters. This kind of awkward girl who didn't understand what she was thinking really made him want to stay away.
Wei Shuxun, who had such an idea, patted himself. The girl does not ask for anything in return and spends time and energy to help him with tuition every night.
I don't know what is the use of learning to make neon lights, but I have a close relationship with several senior seniors. These seniors also have their own interest groups, similar in nature to those of Sun Yi and the others. They all rent a small house in the school as an activity room. However, they openly recruited new recruits, and the group has more people than Sun Yi and the others.
Because of his appreciation for Wei Shuxun, Li Guonan invited Wei Shuxun to join their interest group. Of course Wei Shuxun disagreed. He and Sun Yi were a team and had no idea of switching to others. Li Guonan had some regrets, but he invited Wei Shuxun to play in their group. There was no need to formally join.
Wei Shuxun agreed quickly after thinking about it, mainly because Li Guonan told him that they were teaching the younger generation to make high-frequency circuit supply coils. As soon as the drawings appeared, Wei Shuxun could not refuse. His exposure to electronics is too short, and he has never heard of many things, and he will not give up the opportunity if he knows more about anything.
The high-frequency circuit supply coil is not very complicated to make, there are detailed calculation programs and drawings, and the equipment is also relatively simple buzzer, AEC board, interface board, generator, etc. Although it is not complicated, it is a pure interest group after all. There are not so many electronics for research, so it is only made once. use completely different.
The people in the interest group have some basics in electrical engineering and electronics. Two senior seniors guide, one is Li Guonan, the other does not know. After the two showed the drawings to everyone, they called out a sophomore student and instructed him to make them. Wei Shuxun was the youngest and a newcomer. As soon as Li Guonan asked everyone to come and watch, he was pushed to the end.
Wei Shuxun didn't complain. After reading the drawings, and then looking at the electronic accessories made, he had a general route in his mind. Sure enough, as Li Guonan said, it is a very simple thing. He stayed just for the sake of a few seniors, it's not good to turn around and leave when others are instructing, and he can also see how others make it. In short, this is not too difficult for Wei Shuxun to make electronic production. I don't know why, the sophomore senior always can't do it well. Simple DC is fine, but when it comes to more complex KV regulation and current limiting, problems begin.
"Don't worry." Li Guonan patiently instructed: "The control voltage required for KV regulation is buffered by U21B. If you look carefully at the drawing, you must go through the preset voltage and connect it to the KV feedback before reaching KV. Control voltage. You don't have a good connection on the feedback, do it again."
Wei Shuxun has already gone through it in his mind, watching with his chin on his back. Li Guonan walked to the side to answer the phone, Wei Shuxun watched the man make a mistake again and reminded him: "Hey, wrong, it's a series of high-impedance resistors, not a DC series, and the scaling factor is 1..."
"Noisy!" Probably impatient, the sophomore scolded Wei Shuxun in a low voice: "What do you know, it's because you're arguing on the side that I can't concentrate. "
Wei Shuxun lowered his face. From childhood to adulthood, no one except his parents has dared to scold him like this. It should be said that those who dared to scold him have already been beaten up.
"What's wrong?" A senior came over and asked.
Wei Shuxun pushed up his glasses and reminded himself: I am now a good student, a good student, and cannot fight. Then, with a smile, with a little shyness: "I'm sorry, senior, I'm running out of time, can you let me try it too? It's all right, just touch me and I'll go."
This time it was a bit slow. The sophomore student's electronics foundation seems to be very poor, but they have been selected for production, and it is not easy to change people in the middle. Hearing what Wei Shuxun said, others agreed, and the senior nodded: "If that's the case, let you try it too. Don't worry, everyone has a chance. We are taking turns."
Wei Shuxun pushed up his glasses, smiled and said to the sophomore who scolded him, "Sorry, please let me go."
"Humph!" The man snorted and gave up his seat with a displeased face. "I finally managed to do this step, don't break it for me."
Wei Shuxun sat down and smiled shyly: "Don't worry, I'm not on the same level as you."
The man is still staring, Wei Shuxun has quickly connected the resistance and resistance in series, the KV control has already been made almost, after Wei Shuxun adjusts the resistance in series, it will be done soon KV control. Then directly control the subsequent high frequency and high voltage, and complete the MA streaming.
It took less than ten minutes, after finishing, checking the drawing again, Wei Shuxun stood up and shook his head contemptuously: "Such a simple thing, it takes me so much time, if time If it can be counted as money, I really hope to be compensated.”
Li Guonan sent Wei Shuxun out and rubbed his forehead helplessly: "Are you here to demolish the platform?" I'm not interested." He withdrew, but everyone could see his sternness.
"Sorry." Wei Shuxun shrugged: "I think I'm gentle enough, you should ask him to learn the basics and come back!"
"We're just an interest group."
"So are we." Wei Shuxun pushed up his glasses. No wonder Sun Yi and the others refused to recruit people. But it turns out that you don't need to beat people, you can also achieve the purpose of teaching!
The book says that knowledge is power.
