Tech house system

More than a week later, the modification of the quadcopter was completed, and the four of them made a test flight on the roof of the school building.The quadcopter is mainly used for aerial photography, and it is mainly controlled by remote control. It is a relatively popular application tool.Sun Yi installed an automatic navigation system on the quadcopter and made some technical improvements to make it more flexible and able to bypass obstacles and reach some remote corners.

"Tilt 40 degrees... 65 degrees... 80 degrees..."

On the roof, four people gathered in front of the computer, looked at the results of the aerial photography of the quadcopter, and sent commands to shoot from various angles.

"90 degrees, ok." Sun Yi tapped on the keyboard with both hands, and said with satisfaction: "The test is complete, there is no problem."

The quadcopter flew back and landed firmly on the ground.Wei Shuxun picked it up and praised: "It's amazing."

"Average." Liu Yongdong took it and put it into a cardboard box: "Our level is not enough, we just strengthened our flexibility a bit. I heard that the United States has been automated and intelligent, and we still mainly rely on remote control, which is too far behind. "A look of regret.

Wei Shuxun doesn't understand these things. As a man, he likes quadcopters purely as large toys. He doesn't understand Liu Yongdong's regret, so he just asks curiously: "Then, you guys make quadcopters?" What is it for? For photography?"

"Sneak shot!" Feng Wei smiled and said, "How about flying to the girls' dormitory to take a sneak shot?"

There are three people in that studio. Unlike Sun Yi and Liu Yongdong who are serious and stable, Feng Wei is a very free-spirited person. He wears fashionable clothes, his hair is dyed the color of millet, he knows all about gossip about celebrities, he likes street dance, and his whole body is full of charm. A Korean wave.

——Although Wei Shuxun doesn't pursue stars, the two get along quite well when it comes to having fun.

"Don't talk nonsense." Liu Yongdong kicked him and explained to Wei Shuxun: "It's for sale, don't listen to his nonsense."

Wei Shuxun nodded: "I don't believe it either."

Sun Yi, Liu Yongdong, and Feng Wei are all third-year students, majoring in electrical engineering and automation. They mainly study electrical engineering-related system operation, automatic control, power electronics technology, information processing, etc., which are different from Wei Shuxun's major, but There is an intersection.The knowledge they are teaching Wei Shuxun now is basically what he will learn in the future.

After dinner, Wei Shuxun went for a walk outside the school gate, walked to the commercial street next to the school, and passed the old bookstall beside the road.Walk slowly, turn back, walk, turn back again.Wei Shuxun still doesn't like reading very much. At the beginning of school, he had to make up lessons because of his poor foundation. Now he has basically caught up. If it is not necessary, he really doesn't want to read books all day long.

But making electronic products is really interesting, but unfortunately, Sun Yi and the others taught him techniques that he still can't understand... After a few laps, Wei Shuxun finally walked to the second-hand bookstall.

It was the stall owner from last time. Of course, he no longer remembered Wei Shuxun. When he saw him walking over, he smiled and asked, "Student, whatever books you want, just read them. I have everything here."

The books on the bookstall are really miscellaneous, ranging from "Tong Jian", "Four Books and Five Classics" to entertainment magazines, novels and comics.There are two booths arranged in a mess, one is pirated new books, and the other is genuine second-hand books.

Wei Shuxun found the last two "High Frequency Electronic Circuits" and "Micro-Nano Electronics", and looked through other second-hand books.Most of the second-hand books here are professional textbooks sold by students. The book stall owner knows the student market very well, and basically sells technical books.

"Automatic Control Theory", "Basics of System Identification", "Analog Electronic Technology", "Semiconductor Physics", etc. Wei Shuxun didn't know which major these textbooks belonged to. He just chose all the technical books of the basic class. Come out and buy it all at once. It costs 5 yuan a copy, which is not expensive.

In view of his own personality, Wei Shuxun is not sure whether he can read the book, but he still decides to read as much as he can. Anyway, he is just interested, and has no intention of developing it specifically.

I thought that I would not be able to read the book, but unexpectedly read it with great concentration.For Wei Shuxun, technical books are not as complicated and incomprehensible as English, unlike Chinese. The content is clean and straight to the point. In addition to theoretical explanations, there are production examples, which are very interesting.

After seeing it, I was addicted to it without knowing it. Wei Shuxun even took notes rarely, and wrote down the production examples that he was interested in, and planned to buy accessories for experimentation another day.

For Wei Shuxun, technical books are equivalent to extracurricular books, novels, which he himself read very interestingly.But in the eyes of his classmates, Wei Shuxun spent all his spare time this week reading senior textbooks. It is said that he continued to hold the books after returning to the dormitory after class, and his diligence was enough to make the whole class ashamed.While feeling respectful, Wei Shuxun's reputation as a nerd was confirmed.

"Speaking of which, you should have a learning machine, a method of making electronic products like this?"

"Yes." The learning machine replied.

"How can you give it to me?" Wei Shuxun never expects the learning machine to contribute for free.

"mission rewards."

"Sure enough." Wei Shuxun nodded: "Then you release the task, otherwise I won't get the reward."

"No valuable tasks have been found for the time being." Said the tablet of the learning machine.

Wei Shuxun's task progress is stuck at 16%, and he hasn't moved for a long time.13% of it was earned when he saved people, otherwise it would still be within 3%.

The learning machine has found a shortcut to complete the task, which is to keep sacrificing oneself to save others.An ordinary student sacrificed himself to save others more than ten times, and no one in the whole country dared to say that he was not "great".

It's a pity that this proposal was solemnly rejected by Wei Shuxun, and he was warned never to make the idea of ​​"sacrificing oneself to save others".But in school, in addition to reading, it is reading.Not long after the start of school, the students who have experienced the strong pressure of the third year of high school are playing crazily. Compared with them, Wei Shuxun is already a diligent student, and the learning machine will not force him anymore, so I haven't found a training Wei Shuxun yet. task.

As an intelligent program, the learning machine has no anxiety.Many people become great people in old age, and he has plenty of time to wait.

This weekend Wei Shuxun went to the hardware and electronics wholesale market to buy various accessories and tools, such as screwdrivers, needle-nose pliers, flat files, etc. Professional tools were also bought together, filling a box full.

Walking out of the hardware and electronics wholesale market with the cardboard box in his arms, Wei Shuxun counted the money in his wallet and found that he seemed a bit overdrawn.This month's living expenses were running out, and he was reluctant to take a taxi, so Wei Shuxun went to the bus stop to wait for the bus.

After waiting for a while, Zhou Quan suddenly received a call and asked him, "Where are you?"

"Zhou Quan, are you finished?" Wei Shuxun asked.Zhou Quan didn't know what task he took. Except for the last time he helped Lu Xin, an email came to remind him to pay attention to safety, and there was no more news.Now that I call, I think the task has been completed, so I can contact the outside world.

"Yeah." Zhou Quan still said nothing, and only responded, "I'm here to find you."

"I'm not at school now, it will take more than half an hour to go back, otherwise you..."

"Where, I'll pick you up." Zhou Quan's tone was unquestionable.

Wei Shuxun blinked and nodded: "Okay, sorry to trouble you, at the gate of the hardware and electronics wholesale market."

After waiting for more than 20 minutes, Zhou Quan drove his familiar black Land Rover to pick up Wei Shuxun.Seeing Wei Shuxun holding the box, he immediately got out of the car to help him carry it.

"No, I..."

Before Wei Shuxun could refuse, Zhou Quan had already taken his box.Wei Shuxun could only thank him, and sat in the co-pilot seat.Zhou Quan put the box away and started it.

Wei Shuxun didn't feel particularly missing Zhou Quan, after all, he was a man, so there was nothing to miss.But Wei Shuxun has always regarded Zhou Quan as a good friend, and not long ago he learned that Zhou Quan had died in the original history.Now seeing me again, I am naturally extremely happy.Knowing the mission of the military, I couldn't ask more questions, so I only cared about his body: "Zhou Quan, are you not injured?"

"No." Zhou Quan replied succinctly.

"That's good. Is Grandpa Zhou in good health?"

"It's okay." Zhou Quan said, "You can go and visit."

"Haha, forget it, just say hello to Grandpa Zhou and those two little ghosts for me." Wei Shuxun liked the Zhou family quite a lot, but the Zhou family was a military family, and the family always gave people a sense of righteousness and awe.He is used to being loose, and he doesn't like such a serious atmosphere very much.

"I just finished the task." Zhou Quan suddenly said when he was about to go to University A, "I have to go back to school to report, this time I came to give you something."

"Huh? Are you in such a hurry, can't you leave after lunch?" Wei Shuxun sat up straight and asked in surprise.Seeing Zhou Quan shaking his head, he fell back on his seat in disappointment. "I thought we could talk more. We haven't seen each other for a long time. I planned to have a good chat today!"

The corner of Zhou Quan's mouth curled up slightly, he was very busy with time, and he came here this time just to have a look at Wei Shuxun.Seeing that he was doing well, Zhou Quan felt relieved.Taking advantage of the red light time, he reached out and stroked Wei Shuxun's soft hair: "I'll see you in a few days."

The car stopped outside Wei Shuxun's dormitory, Zhou Quan took out the boxes from the back of the car, besides the tools Wei Shuxun just bought today, there was another smaller plastic sealed box.

"Hey, what is this?" Wei Shuxun took the box and asked suspiciously.

"The accessories you want." Zhou Quan said, seeing Wei Shuxun open the box and showing a surprised look, Zhou Quan just got into the car with satisfaction. "Let's go, goodbye." Before Wei Shuxun could react, he had already left.

The accessories that Zhou Quan gave Wei Shuxun were military electronic accessories that Wei Shuxun proposed to him when he was in the hospital last time.When Wei Shuxun first looked for tantalum capacitor transistors, he sent an email to ask Zhou Quan.What Zhou Quan sent this time, except for the tantalum capacitor transistor that Wei Shuxun wanted, and the various electronic accessories mentioned before, Zhou Quan packed 10 of each kind and sent them in a box.
