Tech house system

These seniors were the last time Wei Shuxun accompanied Sun Yi and the others to participate in the college students' electronic design competition. They saw Wei Shuxun carrying a toolbox alone, and they couldn't see the people who criticized Sun Yi.Wei Shuxun had a good impression of them, and they naturally also had a good impression of Wei Shuxun.These days, it is very rare to find juniors who are calm and willing to endure hardships and stand hard work.Of course, the point is that you are young and not threatening.

This time, it was mainly to help the seniors of the foreign language department to set up the stage.Although there was a performance at the New Year's Day party last semester, the girls in the foreign language department were not satisfied.This is their last semester at the school, so they naturally wanted to be more lively, because the entire foreign language department decided to hold another cultural evening in-house, and for 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 it is for the beauties of the foreign language department, a casual greeting 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, so after thinking about it, they thought of the hard-working elementary school boy last semester.Although the handsome face of the elementary school boy makes people feel uncomfortable, but he is young, he is only a freshman, and he is not threatening. Senior girls will not look at this kind of little brother.

Wei Shuxun didn't know the twists and turns. Several senior seniors asked him to help build the stage, and said they would teach him how to make neon lights, and he naturally agreed immediately.Although the neon light is not very useful, it is still a skill that can be used someday.

The foreign language department also has its own people to arrange the stage, and they mainly help arrange the lighting.Wei Shuxun followed behind a senior named Li Guonan, and his main job was to help him pass tools and move ladders.Li Guonan taught him while doing it.It's not a difficult skill, Wei Shuxun has a good foundation, and he will be able to take over soon.

"Hey, Shuxun, do you want a Coke?" A senior sister threw the Coke over, Wei Shuxun took it casually, and waved his hand: "Thank you!"

"Are you sitting still? Let me help you!" The senior looked at the gentle and handsome junior with a smile, and reached out to support the A-shaped ladder under him.

Wei Shuxun didn't care, he was quite stable sitting on it by himself, but he still said thank you, took the tool and raised his head to adjust the rock lamp, and suddenly a loud voice came from behind: "Wei Shuxun!" He was startled.Turning his head, he saw Li Xiaoran walking towards him full of anger.

"Shuxun, how could you do this?" Li Xiaoran glanced at the senior, pouted her mouth angrily, and said to Wei Shuxun, "You asked us to give you tutoring, it's only been a week, and suddenly you said temporarily Rest, but came here to play, what do you mean!"

Wei Shuxun jumped down from the A-shaped ladder, feeling a little confused. He specially invited them to a meal before, and told them that evening tutoring would be temporarily suspended for a week. Although Li Xiaoran was not very happy at the time, he felt that he clearly said it very well. It's clear, I don't know what Li Xiaoran came here for.

"It hasn't arrived in a week, and the tutoring will resume next week. I'm sorry, if you find it troublesome, you don't have to help me with it." After thinking about it, I can only think that the other party thinks it is troublesome.There was nothing Wei Shuxun could do about it, he was really tired and wanted to relax, so he could only apologize to her.

"You... What do you mean!" Li Xiaoran stomped her feet, her eyes were red: "I kindly helped you with tutoring, but you still despise me!" Saying this, she suddenly ran out.

"..." Wei Shuxun really didn't understand at all, what did he say wrong?

"Idiot!" Senior sister pushed Wei Shuxun: "You still don't chase her!"

"Don't be kidding." Wei Shuxun climbed back up the ladder: "I just loosened the screw, if you leave it alone now, be careful not to drop it when you are dancing."

For Wei Shuxun, who doesn't understand the style, of course, responsibility is more important.Although it is a trivial stage lighting arrangement, it is a job he himself promised to help, and he must be responsible to the end.

In fact, Wei Shuxun just came to help during the breaks when there was no class, and he didn't need it at night. He just used this excuse to rest.So during class during the day, you can still meet Li Xiaoran, there is no need for Li Xiaoran to run to him, it feels too deliberate.But I am a man, so I can't be serious with girls, and she has helped herself.So when Wei Shuxun was in class the next day, he took advantage of the recess to ask Li Xiaoran why he was angry last night.

"I'm not angry at all, really." Li Xiaoran said with a smile, "I'm just worried about you, just remember to come back to study soon, your English foundation is very poor!"

It could be seen that she was really not angry, Wei Shuxun also smiled, and frowned when he turned his head.He found that he really didn't understand what girls were 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 this idea, patted himself. The girl spends time and energy helping him with tutoring every night without asking for anything in return. It's just that she has a weird personality, how can she dislike her!

I don't know what is the use of learning to make neon lights, but I have become close to several senior seniors.These seniors also have their own interest groups, the nature of which is similar to that 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 team has a lot 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 intention of switching to others.Li Guonan felt a little regretful, but he invited Wei Shuxun to play in their group. He didn't need to join formally, he could learn while playing. Anyway, it was an interest group, so it didn't matter whether he joined or not.

After thinking about it, Wei Shuxun quickly agreed, mainly because Li Guonan told him that they were teaching the juniors to make high-frequency circuit supply coils, and Wei Shuxun couldn't refuse as soon as the blueprint came out.His exposure to electronics is too short, and he has never heard of many things, and he will not give up the opportunity to see anything more.

The production of the high-frequency circuit supply coil is not very complicated, there are detailed calculation programs and drawings, and the equipment is relatively simple buzzer, AEC board, interface board, generator, etc.Although it is not complicated, it is a purely interest group after all, and there are not so many electronics for research, so it is only made once, and the students will assemble it, and other people will watch from the side, and Sun Yi and his various electronic accessories. Use completely different.

The people in the interest group have some background in electrical engineering and electronics, and are guided by two senior seniors, one is Li Guonan, and the other doesn't know him.After the two showed the blueprints to everyone, they casually called out a sophomore student to guide him in making it, while the others watched and asked questions.Wei Shuxun was the youngest and a newcomer. As soon as Li Guonan asked everyone to gather around to watch, he was squeezed to the end.

Wei Shuxun didn't complain either. After looking at the blueprints and then looking at the electronic accessories he made, he had a general route in his mind, and only his own experience was left.Sure enough, as Li Guonan said, what he knows is very simple.He stayed only to save face for a few seniors, not to turn around and leave when others were instructing, and he could also see how others made it.In short, this is not a difficult electronic production for Wei Shuxun. For some reason, that sophomore senior can't do it well.Simple direct current is okay, but when it comes to more complicated KV regulation and current limitation, problems begin to arise.

"Don't worry." Li Guonan guided patiently: "The control voltage required by KV regulation is buffered by U21B. If you look at the drawing carefully, you must go through the preset voltage and connect to the KV feedback to reach the KV control voltage. You are on the feedback If it is not connected, try again."

Wei Shuxun had already gone through it in his head, and watched it leisurely with his chin propped up.Li Guonan went to the side to answer the phone, Wei Shuxun saw that the person made a mistake again, and reminded him: "Hey, it's wrong, it's high-impedance resistors in series, not DC series, and the zoom factor is 1..."

"It's so noisy!" Probably because he was impatient, the sophomore scolded Wei Shuxun: "What do you know, it's because you are arguing that I can't concentrate."

Wei Shuxun lowered his face.From childhood to adulthood, no one except his parents dared to scold him like this. It should be said that those who dared to scold him have already been beaten to the ground.

"What's wrong?" A senior came over and asked.

Wei Shuxun pushed his glasses, reminding himself: I am a good student now, a good student, I can't fight.Then, with a smile, with a little shyness: "I'm sorry, senior, I don't have enough time, can you let me try it too? It will be fine in a while, let me touch it and I will leave."

This time it was indeed a bit slow. This sophomore's electronic foundation seems to be very poor, but they have been selected for production, and it is not easy to change people midway.Hearing what Wei Shuxun said, the others agreed, and the senior nodded: "Since this is the case, let you try it too. Don't worry, everyone has a chance. We are in rotation."

Wei Shuxun pushed his glasses, smiled and said to the sophomore who scolded him: "Sorry, please let me go."

"Hmph!" The man snorted and gave up his seat with a displeasure on his face. "I managed to do this step, don't break it for me."

Wei Shuxun sat down and smiled politely and shyly: "Don't worry, I'm not on the same level as you."

The man was still staring. Wei Shuxun had quickly connected the resistance resistors in series. Originally, the KV control was almost done. After Wei Shuxun adjusted the resistors in series, he quickly completed the KV control.Then directly complete the subsequent high-frequency and high-voltage control and MA streaming.

It took less than 10 minutes. After finishing, Wei Shuxun checked the drawings again. Wei Shuxun stood up and shook his head with disdain: "Such a simple thing takes up so much time. Hope to be compensated."

Li Guonan sent Wei Shuxun out, and rubbed his forehead helplessly: "Are you here to disrupt the stage?" The sophomore who had just joined not long ago cursed, "I'm not interested in this kind of bullshit interest group" and quit. But everyone can see his sternness.

"Sorry." Wei Shuxun shrugged: "I think I'm already gentle enough, you'd better tell him to learn the basics before coming back!"

"We're just an interest group."

"So do we." Wei Shuxun pushed his glasses.No wonder Sun Yi and the others refused to recruit people. There are many people with different opinions and different ways.But it turns out that the purpose of teaching can be achieved without beating people!

It is said in the book that knowledge is power, and in one respect it is true!
