Restarting life in Siheyuan

Chapter 197 Experimental Bench
Zhu Xuemei jumped up excitedly.

"Don't worry, eldest brother, I promise to keep an eye on my second brother."

Zhu Xuefeng touched the little girl's head. This girl wanted to ride on the dick's head whenever she got the chance.

"If you have time, you should also find a few books to read. When writing a composition, you need to read more books and understand them. You have to understand how to write and why you write like this. Then your composition will be fine."

Then he turned to look at Zhu Xuesong and said a few words.

"You two can arrange your own time later. I have to go to my godmother's house. I won't be back at night. Let's have breakfast together tomorrow."

It was probably about the radio. Zhu Xuesong deliberately packed the four semi-finished products and radio samples together and went out.

There was a slight breeze, it was really cold, and there were basically no people on the road. When I arrived at Director Wang's house, sure enough, I knew that Zhu Xuefeng was going home today, and Director Wang and Uncle Kong were waiting at home.

"Godmother, you are looking for me. Uncle, you are here too."

"I'm not looking for you, I'm just running an errand for someone. This is the end of military training. How about it? I'm pretty tired."

Director Wang came up to help unload the small bag and touched Zhu Xuefeng's face distressedly.

"This little face is really dark. You said it's just a military training. What are you training in the ravine? You can't train in the school. I heard that many schools train on campus."

Uncle Kong usually would not disturb Director Wang during this time and could only look at Zhu Xuefeng and smile.

"Godmother, didn't you say that it's not good to have a pale face? Now it's darker, and you don't like it."

"What nonsense are you talking about? When did my godmother not like it? She has become so black because she knows that you have suffered a lot."

After looking carefully up and down for a while, he nodded.

"Not to mention, I've lost a little weight. This darkening makes me look more energetic. Yes, I seem to be stronger. Go ahead. Your uncle is looking for you. He's almost running to your camp to find you."

Uncle Kong then took the opportunity to speak.

"Don't blame your uncle for being anxious. I read the letter you left. You said you couldn't run a few more steps to come home. This made me wait for an extra month in vain. Come on, let's talk."

Indeed, a trip. This matter may have been made clear a long time ago, but now it is still necessary to make a trip. Zhu Xuefeng subconsciously does not want to enter the compound.

"Did you bring the radio? Let's take a look at your finished work first."

Zhu Xuefeng stood up and took out the radio from his bag. The appearance design was still good, but it was a bit rough. Of course, the guys in this school factory couldn't compare to professional factories.

"Is this it? So small?"

Zhu Xuefeng designed the most common medium wave and short wave dual-band radio. When Zhu Feng turned on the power switch of the radio, a clear broadcast came at the same time, and he slowly adjusted the station.
The effects are good, much better than today's big radios, with good sound quality and low noise.

Director Wang had already made the tea, but did not say anything. He quietly watched Zhu Xuefeng adjust the channel, a little surprised, but more joyful. The godson said he wanted to make a portable radio last time. How long has it been since he tinkered with it? .

"It's really a radio. It's so small. I don't even know what to say about your hobby."

Uncle Kong didn't know how to express his emotions for a while. Seeing the letter and seeing the real thing were two completely different concepts. This boy's hands-on ability was really strong.

"Is it difficult to produce this thing? Can it be mass-produced?"

"Uncle Kong, this is not difficult to produce. Mass production depends on those transistor factories. It seems that their tubes are not open to civilian use yet. I don't know if other factories can do it."

(This radio uses nine transistors and one diode. At that time, there was a regulation that no more than seven transistors were allowed in civilian products, so everyone just pretended not to know.)

After hesitating for a moment, he added another explanation.

"The cost of this radio alone is more than 160 yuan. The main reason is that the tube is too expensive. I can't say the specifics." "I have the drawings. I will hand them in for you tomorrow and let them worry about it. The radio you mentioned Woolen cloth."

The radio is indeed a hot potato, and Zhu Xuefeng is also worried about the future. With Uncle Kong taking over, he feels a lot more relaxed. Installing the radio is an obsession. Now it seems that there are still many difficulties ahead, so it is better to let go.

This mobile phone is what Uncle Kong is most concerned about. I heard that Zhu Feng has successfully experimented, so he is waiting for the batteries. During this period, he has been looking for the relevant departments. This has forced the relevant departments to study quickly, and finally got a few batteries. Now Can't wait to try it.

"I brought them with me too. There are four sets in total. They have been tested and there are no problems. I just don't have the batteries so I can't try them out."

Uncle Kong smiled mysteriously, got up and went to the study, brought out a big box, placed it on the table, and patted the box.

"I also found a few sets of the batteries you asked for. How about we try them now?"

Zhu Xuefeng looked at Uncle Kong in surprise. How could this battery be so easy to make? Could it be that Lao Mei's battery was obtained through special channels?

I opened the box with hesitation, and I was overjoyed. I really thought too much, how can the old American battery be so easy to deal with.

There were six batteries lying in the box, which were almost twice as big as Zhu Feng requested. Zhu Xuefeng picked them up and looked at the parameters, and finally understood.

The parameters are all in compliance with the requirements. You must be in a hurry. Let's make a cross with qualified parameters. There is no other way. Let's give it a try.

Seeing Zhu Xuefeng's dumbfounded expression, Uncle Kong realized something was wrong and asked quickly.

"Isn't this useful?"

"It works, but Uncle Kong, the thing I designed is called a handstand. It can be grasped with one slap. You see, it is difficult for you to hold this battery. It is too big."

Uncle Kong was a little speechless. Indeed, this thing was too big to be held with one hand. It was almost enough to hold it with two hands.

"Don't worry, let's try the effect first. The battery needs to be researched quickly. After all, the new battery is still a new field for them, so they have to be given time."

Zhu Xuefeng suggested imitating the old American products and directly researching nickel-chromium batteries. As for nickel-metal hydride batteries and lithium batteries, it is too early and unrealistic.

But the technology accumulation of the Beijing Battery Factory is far from enough. It only solved the technology of dry batteries a few years ago. Now it has jumped so much at once, which is really embarrassing.

As for the chemical factory that Section Chief Lu is looking for, Zhu Xuefeng doesn't have much hope. Their battery is a lead-acid battery technology. It's still early to start researching it. I'm thinking about finding time to go shopping on Taobao, but I haven't had the chance.

It stands to reason that research on the batteries that will be used now will only begin in China ten years later. It is said that according to the requirements of Uncle Kong and his department, many experts have been mobilized to work on the problem and have already started. There may be hope for this.

Zhu Xuefeng connected the line, set up a few things, adjusted the channel, and gave it a try. It should be fine.

"Uncle Kong, I've adjusted everything. No matter how you test it, you can't go out for an interview with this bunch of stuff."

Uncle Kong looked at the pile on the table. They were all connected with wires and could not be lifted or carried. He was really embarrassed. He rarely lit a cigarette, and Zhu Xuefeng had to smoke with him.

"On this matter, you two are still having sex at home. Why are you so gloomy? Lao Kong, just call a car and let it go."

"Yeah, why didn't I think of that."

Uncle Kong quickly got up and went to the study to ask for a phone. He came out after a while and asked Zhu Xuefeng.

"Xiao Feng, how far can this thing of yours travel?"

Zhu Xuefeng thought for a while. There were not many buildings in the city now, and there was basically no radio interference.

"This sample should work within two kilometers in the city, and it should also work within ten kilometers on the sea!"

A jeep took away a set of mobile phones and batteries, and Uncle Kong followed the car, leaving only Director Wang and Zhu Xuefeng at home guarding the other one, waiting for Uncle Kong's call.
