"ne555, good thing." Hu Yang pinched an integrated circuit chip with two fingers and was amazed.

In the hut of the wooden model class, Lin Zhenhua was looking at Hu Yang expectantly, waiting for him to draw himself a circuit diagram of the gate controller.

The NE555 is a very simple and practical integrated circuit chip, which has been used by electronics enthusiasts to develop thousands of practical circuits since it was produced in 1971. When Lin Zhenhua was in high school, he was exposed to a little radio technology and knew the application field of 555 circuits, however, because he later studied machinery, the original radio foundation was completely forgotten. When he boasted to the Ministry of Finance that he could make a control system based on the 555 circuit, this system did not even exist.

"What are you looking for me?" After Hu Yang praised the chip, he turned his head and looked at Lin Zhenhua curiously and asked.

"I just want you to design a circuit to achieve such a few functions." Lin Zhenhua handed over a list of the functions he intended to implement.

Hu Yang shook his head: "What are you kidding, how can I design a circuit." ”

"You won't?" Lin Zhenhua was a little unconvinced, "Then you know at a glance that this is a 555 circuit?" ”

Hu Yang pointed to the words printed on the chip and said, "Isn't it printed on this?" Although I don't understand the circuit, I have read some information, how could I not know such a famous chip? ”

Lin Zhenhua still didn't believe it, and asked again: "Lao Hu, do you not understand the principle of the 555 circuit, or do you not understand electronic technology at all?" ”

"I don't understand either." Hu Yang replied dryly.

A smile bloomed on Lin Zhenhua's face: "Really? That's great! ”

"Are you alright, Kobayashi?" Populus was stunned.

Lin Zhenhua tried his best to hold back a smile and explained: "Lao Hu, you don't know, this is the first time I've heard that you still don't understand something." You know, since I met you, I've lost all my confidence. Now I've finally regained my confidence. ”

Hu Yang was stunned for a while before he understood Lin Zhenhua's words and knew that Lin Zhenhua was joking. He also smiled and said: "Look at what you Xiaolin said, I just like mechanical technology more, so I read more books in this area, how can I understand everything." However, I don't think it's too difficult to do these things, and there are a lot of radio enthusiasts these days, so if you look for them, you can probably find someone who understands these things. ”

"I know, I know." Lin Zhenhua said, "Regarding this circuit, I still have some technical information in my hand, and I guess I will find someone who can install a radio, and we will discuss it together, and we will come up with it." Okay, Lao Hu, I won't talk to you anymore, I'll talk about it another day. ”

"Hey, Xiaolin, wait." Hu Yang stopped Lin Zhenhua, who was about to turn around and leave.

"Is there something wrong?"

Hu Yang took out a piece of paper and said hesitantly: "Xiaolin, there is something, I know it is very troublesome, but ......"

Lin Zhenhua said dissatisfiedly: "Lao Hu, between us, what kind of politeness do you have to talk about." If you have anything, just say it, do you want to kick Mrs. Hu and find another young one, and now you lack money to pay for the breakup fee, and you want to borrow some money from me? ”

"You Kobayashi!" Hu Yang scolded, "Make such a joke on me, old man." ”

Lin Zhenhua said with a smile: "Except for this, other things are easy to say." ”

Hu Yang was swept away by Lin Zhenhua, but he threw away the embarrassment. He handed the piece of paper in his hand to Lin Zhenhua and said, "Xiaolin, these are some of the titles I found from the references when I was reading those original books, and I think these books are very important. See if you can get these books through your connections abroad. I know that if you want to buy all these books, it may be very expensive, and the money ...... this aspect" He had the intention to say that he would pay for these books, but he finally didn't say it, because the price of books abroad is very expensive, and it is beyond the financial ability of Populus euphratica to buy all these books.

Lin Zhenhua took the list of books and replied nonchalantly: "No problem, you don't have to think about money, the Americans still owe me favors, this book, for a company of theirs, is a drizzle." Let me see, what kind of books are these......"

Lin Zhenhua looked at this English book list carefully, and the more he looked at it, the more frightened he became: "The Effect of Turbulence on Thrusters", "Noise Reduction Technology", "Complex Surface Processing", ...... Lao Hu, you're playing too much, aren't you? ”

Hu Yang said: "Xiaolin, these are all hobbies, I am more interested in these contents, you see, how much you can buy, if you are too embarrassed...... Alas, forget it. ”

Lin Zhenhua did not debunk the lies of Populus euphratica, of course he knew that there were very few people in this world who could study these things with their hobbies. It is said that there is an idler named Feigenbaum in the United States who once studied these things in a very boring way, and won the Nobel Prize in physics for it, but he is seriously an employee of Los Alamos National Laboratory in the United States, not a woodworker in an inexplicable machine factory.

"Lao Hu, these books were handed over to me, and I immediately wrote to Spischer's agent in Guangzhou, asking them to help pass the book list to Ford. In the future, whatever books you need, just ask me. I don't ask you what you're for, but I believe that reading these books will definitely contribute to the four modernizations. Lin Zhenhua used a popular phrase to explain his meaning.

"Then thank you Kobayashi." Hu Yang said, "As for whether this knowledge is useful to the country, alas, it is difficult to say now." ”

Coming out of the workshop, Lin Zhenhua went to the construction site of the labor service company to take a look, and saw that the simple shed had been erected, and a group of young workers were decorating the interior. The orders signed by Lin Zhenhua and Chu Hongyang in Nandu have been handed over to Zhao Yongqun and Peng Shaozhe, and they are taking several workers to discuss how to prepare materials, how to process and other details. Lin Zhenhua knew that the technical content of these products was not high, and with the collective wisdom of the young workers, they should be able to take it down, so he didn't bother too much.

When I got home from the construction site, I was just in time for my sister Lin Fanghua to come back from school. As soon as he saw his brother, Lin Fanghua shouted happily: "Brother, it's great that you're back." ”

Lin Zhenhua went to Nandu to run business this time and stayed for several days, so Lin Fanghua asked a little. Lin Zhenhua replied with a smile: "What's the matter, is it that I'm not at home, you are afraid alone." ”

"Not really." Lin Fanghua said, "Yang Xin is with me." ”

"If I had known this, I wouldn't have been in a hurry to come back." Lin Zhenhua said.

"No way!" Lin Fanghua said, "I've been looking forward to you for several days. Our homeroom teacher told you to see him as soon as you come back. ”

"Huh?!" Lin Zhenhua was taken aback, "Sister, are you in trouble again?" ”

Lin Fanghua was so angry that she wanted to hit someone: "What do you call again!" When did I get into trouble? ”

"Oh, yes, I haven't been in trouble in the past, so why did I get into trouble this time?"

"Because...... Who said I was in trouble? ”

"If you don't get into trouble, why should the head teacher call the parents?"

"Because ......" Lin Fanghua suddenly blushed and said, "I won't tell you." Anyway, let's hurry up and eat, and you will go to school with me after eating, and our homeroom teacher will be in the office every night, and he said that you will see him as soon as you come back. ”
