Moss, who was sweating profusely, raised his head and found that the speaker was a little boy in his teens. He didn't pay much attention to it and continued to fix it. Seeing that the old master didn't respond, Danny tactfully went to find the information he needed.
The library had all kinds of information. He quickly found information about computers. What surprised Danny was that many computer books were about programming. What was programming? He didn't know, so he first found a book about computers.
Holding the book about computers, Danny began to read it carefully. He gradually immersed himself in the world of computers. He began to understand that computers were electrical devices used for digital calculations. Besides high-speed calculations, they also had many functions for data processing, such as data storage. All calculations and data were completed by 0 and 1 in the computer. There were only two states, on and off. If he wanted to use electrons to calculate it, he had to simplify it into 0 and 1, which represented on and off…
The magic of the computer made Danny's interest grow exponentially. It was as if the computer was a part of his body, an organ. Only now did he realize that this was a new organ that belonged to his body. He began to gradually understand, gradually master, and activate this organ to perform its functions.
Danny sucked the knowledge in the book hungrily. The way of 0 and 1 seemed to be in sync with his thinking. The knowledge was imprinted in his mind. In addition to his deep foundation in electronic technology, the knowledge about computer hardware made it easier for him to understand and digest. Very soon, he had finished flipping through the books on basic computer knowledge. He felt as if he was born with this basic knowledge. As long as he read it once, he would feel as if he had known it for a long time.
He placed the book back on the shelf and took out an introductory operating system book from the shelf. According to the introduction in the book, to master the computer, the first step was to start with the keyboard layout. The keyboard layout was already in the book. If he wanted to familiarize himself with it, he could find an opportunity to practice it in the future. The second step was the operating system. This should be the bridge between the computer and the computer. After reading a few pages, he had a deep understanding of the DOS operating system described in the basic knowledge. The dos system was commonly used in computers nowadays. The DOS system was a pure text system that controlled the computer by entering instructions. The book explained the functions of each instruction in detail. Danny memorized these instructions attentively. From time to time, he couldn't help but glance at the computer in the library. His heart was filled with the desire to put it into practice.
Unknowingly, a long time had passed. The number of people in the library gradually increased. Although there were many people, everyone silently followed the library's rules, so it was still very quiet. Suddenly, an exclamation broke the silence in the library. Almost everyone looked at the source of the sound. Danny looked and saw that it was Master Moss. But at this moment, he felt a chill down his spine. Master Moss was staring at him as if he was an alien.
Danny timidly took a small step back. Mr. Morse seemed to not feel the gazes of everyone at all. He walked over and grabbed Danny's hand, dragging him to the projector."0.13mm coil, 0.13mm coil, how do you know it's broken?”
Master Moss 'sudden behavior made Danny very flustered. He stuttered,"" This, the light projected by this projector is yellowish, and the scanning frequency is rather chaotic. Moreover, it periodically produces a prismatic light. This phenomenon will only appear when the signal is amplified and distorted…"
Old Moss once again looked at the young man in astonishment. He really could not believe his eyes. As a professional repairman, Old Moss could still understand these professional terms. What made him extremely shocked was that even a senior repairman like him had to spend half a day to find the fault with the help of a multi-meter, but this ten-year-old child could determine the fault without the help of any measuring instrument, and it was extremely accurate. It was really shocking.
Old Moss regained his senses and continued to ask,""You, you repaired a projector before?”
"No…I haven't fixed it. This…This is the first time I've seen this electrical device!”Danny was telling the truth. Projectors were only available in science and education places. Ordinary household appliances would not have such things.
This made Old Morse feel even more incredulous. The circuit inside the projector was also very complicated. Without looking at the circuit diagram to understand the principle, there was no way to start. He had repaired this projector a few times, so he naturally had some understanding of its internal structure and working principle.
"Then how did you know that the 0.13mm coil malfunctioned?" Old Morse asked in surprise.”
"Oh, from the functions of this device and the components on the circuit board, I already know the composition of the circuit. Looking at the components on the circuit board, I can find the signal feedback amplification part. The signal feedback amplification part has its own unique component arrangement. Looking at the signal circuit on it, it is formed by a double triode amplification circuit.”
Morse was stunned when he heard this. Just this alone could tell the circuit composition. That was like legendary technology. The cause of the malfunction that the child had mentioned was not wrong at all. However, the malfunction of the coil was found by measuring the parts one by one, unlike this child, who had hit it with one hit. Morse asked carefully,"Did you fix the TV in the club yesterday?”
Moss was indeed very careful when he asked this question. If this child was the one who had fixed the problem that he had not solved, then the technology would be too terrifying. Although the television was a common electrical device, it did not mean that its structure was simple. Just imagine how complicated the circuit work process would be to turn electrical signals into living, incomparably clear moving images. How did the television turn electricity into images? Perhaps laymen simply couldn't imagine how the circuit of a television worked.
"The problem with that TV set is relatively big. After I saw you repair it, I suspected that the resistance of a resistance had changed due to age. However, I wasn't very sure. Therefore, after you left, I used a pencil to paint the resistance through the case. The material of the pencil core is a conducting lead, which can increase the conductivity of the resistance by painting it with a pencil. I estimated the deviation of the resistance and then painted it with an appropriate amount of lead. I haven't tried to see if the TV has been fixed!”
Moss 'eyes began to dull as he muttered to himself,""It's indeed repaired. Am I really old?”
