Chapter 30 Fundamentals of Electrical and Electronics

The surgery and school matters have been settled, and the next thing to solve is the watch video device.

Wei Shuxun once tried to smash it with a hammer, but failed to break the video device.He didn't dare to let go of the video device. The learning machine said that the video device ignored any obstacles. Even if it was buried underground, its image would still appear on the ground.When someone picks him up at that time, if Wei Cheng hates him and spreads some alarmist rumors about him, he will have to die unjustly.

Although the operation was successful, Wei Shuxun has not yet recovered, and Wei Shuxun cannot leave the hospital for the time being.But the hospital is full of people, not to mention the school friends, the people Wei Shuxun saved, and the people who came to visit after watching the news, there are at least a few groups of guests who come to the door every day, and the flowers and fruit baskets received Too much to eat.

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

"Learning machine, how can this thing not be switched on suddenly? Is there a switch?" Wei Shuxun played with the dial and kept turning it. He didn't know how it was connected at that time, nor did he know where the switch was.

"The switch has been damaged." The learning machine said: "The video communication device should be in the on state at present. Once the electromagnetic frequency is connected, it will be connected to the satellite. The basic functions of the video communication device have been completely damaged and cannot be stopped."

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

"I haven't done an experiment, 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 experiment."

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

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

"What is this?" Wei Shuxun asked curiously.

"Drawings for the production of permanent magnetic isolators." The virtual screen is transformed into detailed explanatory text.

"The video device 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 device 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."

Except for the positive and negative poles represented by the two "+" and "-" symbols, what other voltage references, SRAM interfaces and the like are completely unclear.

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

Wei Shuxun has come into contact with a lot of electronic products, but he has never read books on electronics, and he doesn't even have the concept of this aspect.But in the past few days, reading textbooks is boring, and reading other books is a pastime.Although the college entrance examination was approaching, Wei's parents and Wei's mother never asked their son to really go to A University, and asked him to read books such as "Basics of Electrical Engineering and Electronics", although they were puzzled, they still quickly bought them for him.

"Basics of Electrician and Electronics" is a very simple electronic book, which introduces electronic principles and basic circuit diagrams in detail.Wei Shuxun may not be able to read it normally, but after so many days of Chinese, mathematics and English test questions, suddenly there is a new subject, which makes Wei Shuxun feel relaxed and read it purely as an extra-curricular book.

It took three days to finally read it roughly.It’s good to understand the principle, anyway, it’s 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/multiplexers, etc., Wei Shu Xun directly shopped online in the same city, and it was delivered in the afternoon.But Wei Shuxun had never heard of some strange accessories, and couldn't find them online.Wei Shuxun suspected that these were future products, and asked him where to get them.

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

"The blueprint I provided is a modified product. According to the information, all the materials used are in the present world. If you can't find them, maybe the names are different due to changes in the times." The learning machine said: "It depends on you to find it yourself."

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

Soon someone replied: "These are military electronics."

"Huh?" Wei Shuxun was horrified, military supplies, no wonder he couldn't find them!How could he get military supplies!

Fortunately, the other party did not continue to add after a while: "It's not considered military use, but these accessories are rarely used in civilian products, so they are relatively rare. If you have connections, you can get them from state-owned electronic groups."

Wei Shuxun heaved a sigh of relief, and after confirming to the person again that these things were not contraband, when Zhou Quan came over at night, Wei Shuxun made a request to him.It seems that these things are really rare and not difficult. Zhou Quan made a phone call, and someone delivered the accessories immediately.

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

Wei Shuxun smiled and nodded.Zhou Quan is good at this. Although he speaks little and has no expression on his face, he always treats personnel affairs just right and does not interfere too much, which makes Wei Shuxun unconsciously trust and depend on him.

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