MTL - Tech House System-Chapter 30 Electrical and Electronic Fundamentals

Surgery and school have been resolved, the next thing to be resolved is the watch video.

Wei Shuxun tried to smash it with a hammer, but failed to break the video camera. He didn't dare to let go of the video camera. The learning machine said that the video camera ignored any obstacles. Even if it was buried in the ground, its image would still appear on the ground. When someone else picks it up, Wei Cheng, because he hates him, spreads some alarmist rumors to him, and he will only have his share of unjust death.

Although the operation was successful, she has not recovered yet, and Wei Shuxun cannot leave the hospital for the time being. But after all, the hospital is crowded with many people. Not to mention my friends from the school, the people Wei Shuxun rescued, and the people who came to visit after reading the news, there are at least a few batches of guests every day, and they receive flowers and fruit baskets. Too much to eat.

In the hospital, Wei Shuxun had almost no time to be alone, but he was worried that if the video camera suddenly turned on again, what would he do if Wei Cheng was released? Being seen by others can't even explain.

"Learning machine, how can I keep this thing from turning on suddenly, is there a switch?" Wei Shuxun played with the dial and kept turning it. He didn't know how it was turned on at the time. I don't know where the switch is.

"The switch has been damaged." The learning machine said: "The video camera should be in the open state at present. Once the electromagnetic frequency is connected, it will be connected with Weicheng. The basic function of the video camera has been completely damaged and cannot be Prevent."

"It's too dangerous." Wei Shuxun threw the video camera: "Learning machine, you said, if you throw it into the sea, you shouldn't be able to see it, right?"

"I haven't tested it, so I can't be sure." The learning machine replied: "There is a 50% chance that the image will appear on the sea, and you can test it."

"Forget it." Wei Shuxun waved his hand: "Is there no other way? I'm not afraid of Wei Cheng killing me now, I'm afraid that he will suddenly appear." In fact, he didn't really want to destroy it. The video recorder, instinctively wanted to keep it.

The learning machine silently calculated. After more than ten minutes, a virtual screen popped up in front of Wei Shuxun's eyes, and a drawing was displayed on the screen.

"What is this?" Wei Shuxun asked curiously.

"Permanent magnet isolator making drawings." The virtual screen is converted into detailed explanatory text.

"The video camera communicates by sending out an electromagnetic permanent magnet. When the frequency of the permanent magnet is synchronized, the image will be connected. You can try to cut off the permanent magnet, so that the video camera cannot be connected."

"There is such a thing!" Wei Shuxun looked at the drawing in surprise, and after a while, let go: "I don't understand."

In addition to the positive and negative electrodes represented by the two "+" and "-" symbols, what other voltage references, SRAM interfaces, etc.

"It seems that you still need to learn basic electronics and electrical appliances." The learning machine said.

Electronic product Wei Shuxun has been in contact with a lot of electronic products, but he has never seen electronic books, and he does not even have the concept of this aspect. But in the past few days, I am tired of reading textbooks, and reading other books is regarded as a pastime. Although the college entrance examination is approaching, Wei's father and Wei's mother never asked his son to really take the A university entrance examination. He suggested to him to read books such as "Electrical and Electronic Fundamentals". Although he was puzzled, he still quickly bought it for him.

"Electrical and Electronic Fundamentals" is a very simple electronic book, which introduces the electronic principles and basic circuit diagrams in detail. If it was the usual Wei Shuxun, he might not be able to read it, but after doing so many test questions in Chinese, mathematics, and English, suddenly there was a new topic, which made Wei Shuxun feel relaxed and read it as an extracurricular book.

It took three days to finish reading it. It is good to understand the principle. Anyway, it is not an exam. The main gain is to understand the electronic circuit diagram and structure, and then compare the drawings provided by the learning machine, and finally understand what is written on it.

"However, what accessories are learning machines, optocouplers, active filters, and ANALOG high-precision connectors?" Basic tools, integrated circuit boards, A/D converters, analog switches/multiple For things like routers, Wei Shuxun directly purchased online in the same city, and it was delivered in the afternoon. But some strange accessories, Wei Shuxun has never heard of it, and can't find it on the Internet. Wei Shuxun suspected that these were future products, and asked him where to get them.

"I spent so much energy, don't tell me it's for nothing!" Wei Shuxun narrowed his eyes dangerously.

."

This is also possible, Wei Shuxun took out the scratch paper, drew the appearance and names of these accessories compared to the pictures, and sent them to the Internet for inquiries.

A quick reply: "These are military electronics."

"Huh?" Wei Shuxun is thrilled, military supplies, no wonder he can't find it! How could he get military supplies!

Fortunately, the other party continued to add: "It is not military, but civilian products rarely use these accessories, so it is relatively rare. If you have a way, you can get electronic products from state-owned enterprises. The group got it."

Wei Shuxun breathed a sigh of relief, and after confirming to the man again that these items were not contraband, when Zhou Quan came over at night, Wei Shuxun asked him. It seems that these things are really only rare and not difficult. Zhou Quan called, and someone immediately sent the accessories.

Zhou Quan also knew that Wei Shuxun was studying electronics recently, and did not dislike him reading miscellaneous books at the critical moment of the college entrance examination. After explaining the test questions to Wei Shuxun, he touched his head: "Don't be too tired. ."

Wei Shuxun smiled and nodded. This is what Zhou Quan is good at. Although he doesn't speak much and his face is expressionless, he always treats personnel properly without interfering too much, making Wei Shuxun unconsciously trust and rely on him.

If he had an older brother, he would probably be like Zhou Quan!
