MTL - Tech House System-Chapter 41 technical textbook

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. The quadcopter is mainly used for aerial photography and is mainly controlled by remote control. It is a relatively popular application tool. Sun Yi added an automatic navigation system to the quadcopter and made certain technical improvements to make it more flexible and able to bypass obstacles and reach some remote corners.

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

On the roof of the building, four people gathered in front of the computer, watching the results of the quadcopter aerial photography, and sending 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, no problem."

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

"General." Liu Yongdong took it and put it in the carton: "Our level is not enough, we just strengthened a little flexibility. I heard that the United States has been automated and intelligent, we still mainly Relying on the remote control, it's too much." A look of regret.

Wei Shuxun doesn't understand these things. As a man, he likes quadcopters. He just treats it as a large-scale toy. He doesn't understand Liu Yongdong's regret. He just asked curiously: "Then, what are you doing with quadcopters? For photography?"

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

There are three people in that studio. Unlike Sun Yi and Liu Yongdong, who are serious and steady, Feng Wei is a very outgoing person. , I like hip-hop, and the whole person has a Korean wave style.

—Although Wei Shuxun doesn't chase 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 him."

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

Sun Yi, Liu Yongdong and Feng Wei are all juniors, majoring in electrical engineering and automation. They mainly study electrical engineering-related system operation, automatic control, power electronics technology, information processing, etc. Wei Shuxun's majors are different, but they overlap. The knowledge they teach 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 book stalls by the roadside. Walk slowly, turn back, walk, turn back again. Wei Shuxun still doesn't like reading very much. At the beginning of school, he would have to make up lessons because of his poor foundation. Now he has basically followed 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 teach him, he still doesn't understand the technology... After going around the place a few times, Wei Shuxun finally walked to the used bookshelf.

I was the owner of the stall last time. Of course, he didn't remember Wei Shuxun. When he saw him walking over, he immediately asked with a smile: "Classmate, what book do you want, just read it, I have everything here. ."

The books on the book stand are indeed quite mixed, from "Qualification Tongjian", "Four Books and Five Classics" to entertainment magazines, novels and comics. There were two stalls, one for pirated new books and the other for genuine second-hand books.

Wei Shuxun found the last two books "High Frequency Electronic Circuits" and "Micro-Nano Electronics", and flipped through other second-hand books. Most of the second-hand books here are professional textbooks sold by students. The book stall owners know the student market very well, and they sell mostly technical books.

"Automatic Control Theory", "Basics of System Identification", "Analog Electronic Technology", "Semiconductor Physics", etc. Wei Shuxun doesn't understand which major these textbooks belong to, he just Pick out all the basic technical books and buy them at once, 5 yuan a piece is not expensive.

In view of his personality, Wei Shuxun is not sure if he can read the book, but he still decides to read as much as he can. Anyway, he is just interested and has no plans to develop in this area. .

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

Technical books are equivalent to extracurricular books and novels for Wei Shuxun. He himself is very interesting to read. But in the eyes of classmates, Wei Shuxun spent all his spare time this week reading textbooks for senior grades. At the same time with respect, it also confirmed Wei Shuxun's reputation as a nerd.

"Speaking of, learning machines, you should have such a method of making electronic products, right?"

"Yes." The learning machine answered.

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

"Mission reward."

"Sure enough." Wei Shuxun nodded: "Then you release the task, otherwise I will get the reward."

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

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

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

Unfortunately, this proposal was solemnly rejected by Wei Shuxun, and he also warned him to never take the idea of ​​"save oneself". But in school, in addition to reading, is reading. Not long after the start of school, the students who had experienced high school pressure were playing crazy. Compared with them, Wei Shuxun was already diligent in reading, and the learning machine would not force him any more, so I haven't found a training Wei Shuxun yet. task.

As an intelligent program, the learning machine is not anxious. Many people become great after old age, and he has time to wait.

This weekend Wei Shuxun went to the hardware and electronics wholesale market to buy various accessories and tools, screwdrivers, needle nose pliers, flat files, etc. These ordinary tools are not mentioned, even electric soldering irons, mini bench drills , I also bought more professional tools such as spiral micrometer, and filled a full box.

Walking out of the hardware and electronic wholesale market with a cardboard box, Wei Shuxun calculated the money in his wallet and found that he seemed to be overdrawn. This month's living expenses are not much, and he is reluctant to call. Wei Shuxun honestly went to the bus station and waited for the bus.

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

"Zhou Quan, is your business done?" Wei Shuxun asked. Zhou Quan didn't know what task he took, except when he helped Lu Xin last time, he received an email asking him to pay attention to safety, and there was no news. Calling now, I think the mission has been completed, so I can communicate with the outside world.

"Well." Zhou Quan still said few words, and only answered, "I'm coming to find you."

"I'm not at school right 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 beyond doubt.

Wei Shuxun blinked and nodded: "Okay, please, the door of the hardware and electronics wholesale market."

After waiting for more than twenty 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 and helped him get it.

"No, I..."

Before Wei Shuxun refused, Zhou Quan had already taken his box. Wei Shuxun could only thank him and took the passenger seat. Zhou Quan put the box away and started it.

Wei Shuxun didn't particularly miss Zhou Quan, after all, they were all men, so there was nothing to miss. But Wei Shuxun has always regarded Zhou Quan as a good friend, and not long ago learned that Zhou Quan had died in the original history. Now that I see myself again, I am naturally very happy. Knowing the mission of the military, I can't ask more questions, so I only asked about his body: "Zhou Quan, are you not injured?"

"No." Zhou Quan answered succinctly.

"That's good, is Grandpa Zhou okay?"

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

"Haha, forget it, you can say ok to Grandpa Zhou and those two little devils on my behalf." Wei Shuxun likes the Zhou family very much, but the Zhou family is a military family, and the family always gives The feeling of being upright and awe-inspiring. He was used to being casual and didn't like such a serious atmosphere very much.

"I just finished the task." When he was about to arrive at a big, Zhou Quan suddenly said: "I have to go back to school to report. This time I am here to give you something."

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

Seeing that he was doing well, Zhou Quan also felt relieved. Taking advantage of the red light time, he reached out and touched 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 box from the back of the car, in addition to the tools Wei Shuxun just bought today, there is another smaller plastic seal box.

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

"The accessories you want." Zhou Quan said, seeing Wei Shuxun opening the box, he immediately showed a look of surprise, and Zhou Quan got on the car with satisfaction. "Let's go, goodbye." Before Wei Shuxun could react, he had already left.

The accessories Zhou Quan gave to 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, in addition to the tantalum capacitor transistors that Wei Shuxun wanted, and the various electronic accessories mentioned before, Zhou Quan all packed 10 pieces of each type and specially sent them here.
