"Of course." Feng Wei took it for granted, "You also want to come together."

"I don't know anything about electronics, so I'm afraid I can't help." Although he has learned a little basics of electrical engineering and electronics, compared with the three of them, his own basics are nothing, and Wei Shuxun is very self-aware.And he doesn't like participating in these kinds of games.

"The focus of this competition is to comfort Liu Yongdong's broken love." Feng Wei patted him on the shoulder: "It is enough for you to bring your heart."

"I don't like to participate in any competitions." Wei Shuxun said bluntly: "I can't just stand aside and watch you busy, so forget it, and call me if you need to help."

"No, you must participate." Feng Wei insisted: "The three of us are all participating, how can we let you run away. If you are friends, don't refuse."

"You guys know my level." Wei Shuxun still refused: "I can't help, and I don't want to take advantage of it...

Beep——! !

Hearing the electronic sound suddenly, Wei Shuxun smiled slightly, and had a bad feeling. "I'm sorry, I took a call." Pretending to make a call, he walked out of the door and called out the void screen. Sure enough, he saw a new task: "Participate in the National Undergraduate Electronic Design Contest and get a ranking."

Wei Shuxun clenched his fists: "Learning machine, are you unresponsive?" I didn't say anything just now, but I refused to release the task.

"I thought you would participate." The learning machine's voice was flat: "I hope you have the ability to learn independently." The learning machine does not take pleasure in forcing people. If Wei Shuxun can consciously be an excellent student, it will not even appear at all.Of course, it doesn't matter if you have to force the task, the learning machine doesn't care whether the user likes him or hates him.

Wei Shuxun doesn't care about the learning machine, although the tasks released by the learning machine are usually against his wishes, but it is really for his own good.Wei Shuxun is not a person who doesn't know what is good or bad, so he just told him: "Next time you have any task, you can post it directly. Don't wait for me to refuse to post it, so as to save trouble."

"Yes." The learning machine replied.

Wei Shuxun returned to the laboratory again and agreed to participate in the competition together.Although the three were puzzled that he had suddenly changed his mind, they were more than happy that he was willing to participate.This competition is not for prize money, nor for rankings, it is simply to compete for popularity. It is enough for friends to work together, and it doesn't matter who is more capable and pays more.

The National Undergraduate Electronic Design Contest is a regular competition held every year, usually in mid-September, targeting all college students.The number of participants in each group is limited to less than 9 people. There are no restrictions on schools and majors. As long as you have a student ID card, you can sign up.It has been held for more than ten years in total, and it is a very authoritative competition among engineering students.

The registration method is very simple, just send the scanned copy of the student ID card of the participating team members to the official registration mailbox.At the same time, the contact number and competition design information are also attached.It includes design ideas, pictures of finished products, and a small part of technical information.

After the preliminary inspection by the competition official, outstanding works can be selected to participate in the semi-finals.The competition time is only 4 days, and the competition method is too free. There are as many as thousands of students signing up every year, so this method can only be used to screen high-quality products.

The time is short, and the finished product must be produced immediately, and the technical information must be summarized.Regarding what to design for the competition, Sun Yi was rather rigid, and proposed the electromagnetic gun that has become very popular among engineering students recently.The three of them are good at technical improvement, they can improve the electromagnetic gun, and it is no problem to make a beautiful little toy.

"That can't be considered a design, and the electromagnetic gun is offensive, and the referee teacher won't like it." Liu Yongdong shook his head: "I think products related to solar energy should be considered. Now solar energy is the mainstream."

"The time is too short, so I can't think of it." Feng Wei scratched his head: "There is no shortage of electronic products in society now. It is too difficult to have novelty and practicality. I think it is better to make some fantasy things, such as flying saucers or something." Yes, modified with a quadcopter."

"That's just a fantastic appearance, and the technology is not in line with the concept of the electronic design competition." Sun Yi retorted.

Wei Shuxun is completely ignorant of electronic technology. The most high-end electronics he has come into contact with is the future learning machine, which is already ahead of its time.Secondly, there are only mobile phones and computer games. He doesn't know what the electromagnetic gun Sun Yi is talking about.

Listening to the trio make various proposals, which were then overruled by themselves.Wei Shuxun found that his understanding of electronics was far from enough. He thought that he had read a lot of e-books anyway, and he was considered a little skilled. Only now did he realize that he hadn't even touched the door.

The three argued for a long time, and the more they understood the electronics industry, the more they felt that nothing was rare.Things that ordinary students have never heard of, such as quadcopters, are similar to common toys in their eyes, and they feel that there is nothing new about any electronics, let alone "design".

"I said, there is one thing that I don't know if it can be made?" Wei Shuxun raised his hand, saw the three people looking at him, and raised his mobile phone: "You also know that mobile phones often have poor signal, or can't connect to wifi, And the TV, the radio often has poor signal. Can you make something that boosts the signal? I think this is also practical? And it can be sold to technology companies.”

After Wei Shuxun finished speaking, seeing the three of them looking at him together, they blinked: "Why, is this thing already available in the market?" He is out of date again?

"No, not yet." Liu Yongdong shook his head and said excitedly: "Yes, the signal booster is both innovative and practical, and it couldn't be better!"

Is it easy to listen to him?Wei Shuxun was delighted: "Is there any technical problem?"

"No problem." Sun Yi adjusted his glasses: "The main directions are high-frequency electrons and permanent magnetic signals. It's not too difficult to say, but I haven't thought about it before."

After deciding on the research goals, the three of them immediately got busy.Liu Yongdong was in charge of formulas, Sun Yi was in charge of design drawings, and Feng Wei prepared tools and accessories.Wei Shuxun is responsible for... Be quiet and don't disturb.Although he has a little foundation in electrical engineering and electronics, and has read a lot of books, they are all limited to theory, and it is basic theory, so he can't help him with anything.This is also the reason why he refused to participate in the competition at the beginning, the prize money and the ranking were not what he deserved, and he didn't want to take advantage of it.

Liu Yongdong was bored watching Wei Shuxun, and said to him: "Go back, didn't you buy a lot of accessories? Go back and practice your hands, and it will help you after you get familiar with it."

Wei Shuxun could only nod: "Okay, call me if you need anything."

The production method of solar energy storage is not simple, but with detailed design drawings, it is not difficult to do.Wei Shuxun had to repeat several times at the beginning, and even broke a few accessories, but later it became smoother and smoother, almost in one go, and half of it was completed by the evening.

Wei Shuxun put all the accessories in the drawer and put on his backpack.Zhou Quan's training tonight is knives, and Wei Shuxun is looking forward to it.

Before leaving the school gate, I received a call from Zhou Quan, asking where he was.Wei Shuxun was about to reply when he heard the sound of a car.Zhou Quan's car slowly stopped beside him, Wei Shuxun got into the car quickly, and asked, "Why is it so early today?"

As soon as he sat down, he greeted Zhou Quan's hand.I don't know why Zhou Quan likes to touch his head so much, Wei Shuxun is used to it too, Zhou Quan is older than him and takes good care of him, Wei Shuxun treats him as his elder brother, so he doesn't care about his kissing behavior.

"I'm sorry, I have an urgent task." Zhou Quan said with an apologetic face, "I can't help you train today."

Wei Shuxun understood: "It's okay, work is important. Just call me and tell me, there's no need to come here."

Zhou Quan remained silent, and stroked Wei Shuxun's soft hair again.Wei Shuxun turned his head to look at him, with undisguised concern in his eyes.Zhou Quan squinted his eyes, and stretched out his hand to embrace Wei Shuxun in front of his chest.

"Zhou Quan?" Wei Shuxun was puzzled.

"Xu Yuanjun will come to your school in two days." Zhou Quan whispered in his ear: "Pretend not to know him."

task?

Wei Shuxun nodded, and asked in a low voice, "Is there any bugging here?" Why did you hug him and talk?

Zhou Quan patted his head again and let him get out of the car: "Be careful."

"You are." Wei Shuxun laughed, he would not be in any danger at school: "Be careful."

Beep————! !

After Zhou Quan drove away, Wei Shuxun turned on the void screen, and the task showed: learn attack skills from Zhou Quan.Mission completed: 100%, mission reward: not discussed.

The learning machine is very flexible. Now that Zhou Quan no longer teaches Wei Shuxun, the task is considered complete.As for the task rewards, since Wei Shuxun didn't mention it, the learning machine was left alone.Wei Shuxun doesn't have any place to learn the machine right now, so naturally put it away for later use.

The next morning, when I went to the laboratory, I found that Sun Yi and Liu Yongdong had already written the formula and design drawings, and the speed was so fast that Wei Shuxun was amazed.At the same time, I sighed at the girl's lack of vision. The student union, class leaders, and various competition rankings, ordinary students may need these to enrich their resumes, but how can students who are truly capable be so rare.

If it weren't for being stimulated this time, Liu Yongdong and the three would never waste their energy participating in this kind of competition.

Wei Shuxun tried his best to help, but he couldn't help, because the design drawing has not been finalized yet, and computer signal simulation is needed. This is Feng Wei's specialty. The three of them crowded in front of the computer, discussing from time to time: Axisizers should be able to enhance the joint transmission of air signals."

"No, the error value in wireless transmission is difficult to control, and the permanent magnetic coupling alone is not enough."

"I think signal filtering can be measured with pole stretch sensing."

Wei Shuxun stood behind and listened carefully. He had read the book "High-Frequency Electronic Circuits" and also learned some "Micro-Nano Electronics", "Analog Electronics Technology", and "Basics of System Identification". Although I just swallowed jujubes wholeheartedly, I finally understand a little basic principle.Now studying behind the three of them, I can actually integrate the techniques I have learned indiscriminately.

After a busy day, the simulation experiment failed, and all the design drawings had to be overthrown and restarted.The three of them have long been used to it and don't care about it.Wei Shuxun was surprised: "Redesign again?"

In the morning, there were more than ten sheets of draft paper for the design illustrations and formulas. After a day of experimentation, there were hundreds of papers for revision. After a hard day, the final result turned out to be completely overturned and redesigned?Wei Shuxun just sat in for a day, and felt hard and worthless for them.

"No way, the design idea went astray from the very beginning." Sun Yi explained seriously: "Permanent magnetic coupling can complete specific tasks through the air medium, but it has unstable signals, because the signal has error values ​​in the air, so it may Signal filtering is required..."

"Okay, don't be so serious." Liu Yongdong patted him on the shoulder and smiled at Wei Shuxun: "It's very common to overthrow all design mistakes. You are in the basic learning now, it's best not to read the information first , so as not to be led astray by mistakes. Wait until we find the right direction."

Feng Wei nodded: "You have to get used to it. It's very common to do thousands of experiments on a design. After thousands of experiments, it may fail completely." This way, you have to be mentally prepared. Electronic products are fun, but the process of making them is boring and hard, and there are no shortcuts.”

Wei Shuxun glanced at the three serious friends one by one.When they first met, they were making a quadcopter. The experiment took two weeks and sold for 5 yuan, which surprised Wei Shuxun.They are worried that Wei Shuxun regards electronic production as a fun and money-making thing.

This is not in line with their philosophy, and it will easily lead Wei Shuxun to go astray.The road to technology can only be down-to-earth, there are no shortcuts, and the mentality of making money cannot be embraced.Especially in the early stage of study, many people only learn ordinary skills, but they are disgusted with not being able to make money and give up continuing their studies.Wei Shuxun really started to pay attention to electronic production because of the 5 yuan he earned from selling quadcopters.Although it wasn't the main reason, the three of them felt keenly that before Wei Shuxun just thought it was fun, but later it was learning with purpose.

They value Wei Shuxun and hope that he can become a like-minded friend. This time, forcing Wei Shuxun to participate in the competition is a kind of guidance and warning.

Wei Shuxun is not an idiot, he likes electronics, partly because of the 5 yuan.He has decided not to make money from billiards gambling, so he naturally wants to find other ways.When reading a book, while studying, I also think about what things can be made after learning these technologies, and whether they can be sold for money.Although a philistine, it does not prevent him from sincerely liking various electronic technologies.

"I will study down-to-earth." Wei Shuxun smiled: "Don't worry, even if I want to have a common topic with you, I will work hard."
