"Slap in the face."

The system is a scam. Which laboratory is this produced? It’s a scam. The solar panel is directly connected to the battery. Damn, is this too much? What about the controller? Are you getting kickbacks?

"The controller seems to need a chip."

Li Anle said heartily, you are also banned from selling the system, what a hell.

"Let's get a voltage regulator first. It's better than connecting it directly to the solar panel." I never thought that the development of domestic solar energy technology was not that good. I thought that solar energy technology has been around for a long time and has matured.

Thinking too much.

After packing up the solar panels and batteries, Li Anle left the dormitory and went to Teacher Yang to ask for leave first. Then he went out on Sunday to buy a voltage regulator. Li Anle remembered that the 78 series three-terminal integrated voltage regulator seemed to be quite good.

After using it, there are still some enthusiasts using it decades later.

I don’t know if it has been released now. If not, I can only fiddle with it in the simulation laboratory.

"Classmate Anle, go out."

"Yes, Yimin."

Li Anle slapped his forehead. You are right. Ding Yimin is engaged in integrated circuits. "Yimin, let me ask, does your current factory produce three-terminal integrated voltage regulators?"

"Stabilizer?"

Ding Yimin was confused. "Why do you need this? Our factory's latest product happens to have a three-terminal voltage regulator."

"That's great."

Li Anle didn't expect that there really was one. He thought it hadn't come out yet, so now he was saving glory points. "Where can I buy it?"

"It has just been produced and has not been launched yet."

"Ah, that's it. I wonder if there is any channel where I can buy it?"

"Do you need it urgently?"

"yes."

"Okay, I'll take you there tomorrow." Ding Yimin said.

"Isn't this too much trouble for you?"

"It's okay, I just have to go back."

Li Anle accompanied Ding Yimin to say hello to Yang Shiqiang and will go out tomorrow and Sunday.

"Why are you going to the factory?" During dinner in the evening, Han Rongrong and Chen Xiaowen planned to go to Xinhua Bookstore to buy books tomorrow and asked Li Anle if they would go. Li Anle told them about going to Ding Yimin's factory.

"Buy some voltage regulators."

"What did you do again?"

Han Rongrong was curious. Li Anle would always tinker with something. You must know that Li Anle tinkered with a car before. Although it was not a serious car, it was enough to bluff people.

"Nothing, just a little thing."

Li Anle said in her heart, we can't talk about this. I want to give you a big surprise. Han Rongrong also thought that Li Anle didn't want to know, because she was afraid of telling her mother and Aunt Zeng. "Forget it, I'm still happy to know."

"Why are you still angry?"

Li Anle Didigu, little girls are really difficult to take care of. Sooner or later, they will beat you until you call them daddy.

"Sister, how are you going tomorrow?"

"Let's ride a bike."

I originally thought about going with Li Anle, as it would be faster to ride a three-wheeled motorcycle.

"Otherwise, I'll send you there first," Li Anle said. "I'll go do some business later."

"This is too much trouble."

"No trouble, riding a bicycle is too slow."

"You really don't want to delay your business?"

"No delay, I'll just do something small."

Li Anle said, turning around and telling Yimin, "later."

On Sunday morning, Li An got up happily, sent Chen Xiaowen and Han Rongrong to Xinhua Bookstore, and hurried back to school.

"I'm sorry Yimin."

"fine."

Ding Yimin was a little stunned. Li Anle was riding a brand new three-wheeled motorcycle. You must know that these three-wheeled motorcycles are similar to the BMW and Benz of later generations, and are even taller than the average BMW and Benz.

"This car belongs to a relative of mine."

Li Anle said casually, "Borrow it for a ride."

"oh."

Ding Yimin said to himself, you have so many friends, classmates, and relatives.

"Yimin get in the car."

"Classmate Anle, are you sure there is nothing wrong with you?"

"Don't worry, my driving skills are top-notch." Li Anle assured him, patting his chest.

"All right."

Ding Yimin got into the car, still a little worried. "Drive slowly, don't be in a hurry." But after a while, Ding Yimin became restless. The speed was a bit fast, the wheels were a bit fluttery, and she felt very panicked.

"Slow down, okay."

"I'm not afraid that I won't have enough time."

"It's coming in time, it's coming in time."

Ding Yimin said in his heart that life is more important.

Arriving at the integrated circuit factory, Li Anle followed Ding Yimin into the factory very easily. Li Anle was a little confused. Integrated circuits are supposed to be high-tech in this day and age, but at first glance, they were all welded by hand.

"How about it?"

"Awesome, I'll just meet you once."

"Let's go."

Ding Yimin came to collect his salary and met a few friends before taking Li Anle out of the factory. "The voltage regulator you want."

"How much?"

"How much do several voltage regulators cost?"

Ding Yimin's words surprised Li Anle. Normally, Ding Yimin didn't speak loudly. It seemed that he was returning to a place he was familiar with. "Then I'll treat you to dinner."

"That's too polite. Let's go back to school to eat."

"Thank you then."

Li Anle was not too polite to follow Ding Yimin. Besides, he had to go to Xinhua Bookstore and sent Ding Yimin back to school. Li Anle went straight to Xinhua Bookstore without delay.

"You are here. If you don't come, we will starve to death."

"Come on, I'll treat you."

Li An smiled and said, "Capital Restaurant."

"Cuihua Building." Han Rongrong thought it was a good place to go.

"forget it."

Han Rongrong knew about Capital Restaurant, which previously had a restaurant called Cuihualou Restaurant, which was a relatively famous restaurant, specializing in Shandong cuisine.

"How about roast duck?"

“Capital Roast Duck Restaurant?”

The current name of the Capital Hotel is very simple.

"Then it's Capital Restaurant."

Although they were quite greasy, I really didn't want to eat the roast duck. When they came to the place, Chen Xiaowen pulled Li Anle. "Anle, isn't it very expensive here? How about we go back to the school cafeteria to eat."

"Sister, it's okay. Besides, when I go back to the cafeteria, where can I find something to eat?"

"It's rare to come out and have a good meal."

"Sister Wenwen, I'm treating you."

Han Rongrong's wallet has been bulging recently. Li Anle heard Han Rongrong's treat. "Okay, sister, you can order a few more dishes to try later. There are quite a lot of specialties in this restaurant."

"snort."

Braised sea cucumber with green onions, fried mandarin fish, braised prawns, agar-agar soup, a few snacks, and Sixi steamed dumplings.

"Just another hibiscus dish."

Li Anle smiled and said, "Forget about red grilled shark fin and butterfly sea cucumber."
