Seventy-year-old book: The villain Zaizai’s best mother

Da Zhuang has been learning how to assemble radios from Lou Yuhui these days. He has spent so much time learning that he forgets to eat and sleep, and wishes he didn't even go to school.

Of course Gu Nianjun didn't have that ability, but he had the ambition and curiosity and fully supported Da Zhuang.

Miao Miao and Er Zhuang followed Xia Mingshuang when he was studying junior high school textbooks, and naturally followed when Da Zhuang was studying junior high school physics and chemistry.

Now that Da Zhuang and Lou Yuhui are working on assembling radios, they will naturally follow suit.

Assembling a radio is not a simple matter, how to route the circuit, how to arrange it, and how to solder the electronic components so small.

The tools were all brought by Lou Yuhui. The base of the radio was a metal plate that they asked Gu Yunshan to weld for them. They made the rest themselves.

They need to solder those electronic components themselves using soldering tools. Such precision and small electronic components will almost fail, so they cannot try it easily.

Lou Yuhui arranged a task for them, asking Da Zhuang to learn welding first and practice with other things.

So Da Zhuang and Lou Yuhui welded a new hairpin to San Gu today, and welded earrings and rings to Xia Mingshuang tomorrow, or helped Miao Miao weld a pencil cap so that those pencil tips could be plugged in for further use.

They can even weld broken locks or drawer pulls at home, and they can also help weld the tools of Dr. Lou and Dr. Qian next door.

Only when you learn to solder and have a steady hand and a steady eye can you really touch electronic components.

During this period, they used up the large battery Lou Yuhui brought twice, and then went to Cai Shengang's home in the county seat to recharge.

This kind of large battery can be used to plug in to listen to radios and watch TV, but it cannot drive machines with too much power, not even fans, so Xia Mingshuang's electric fans have to wait until the water wheel pump power station is built.

Gu Yunshan helped Gu Jialing contact the machinery factory. They were willing to provide certain discounts in the form of targeted poverty alleviation. For 1000 yuan, they could help install two sets of water turbine pumps and a water turbine generator.

Generators all have power levels, and there is a limit to how much power they can generate at each level.

There happens to be a small natural dam on the west side of the Gujialing River. It has its own water level difference and full hydraulic power. It can install a water pumping station and a water turbine generator.

The water wheel pump can raise the water head to about ten meters, irrigating the water below to the top, and then the commune members dig ditches to lead it to the fields.

The generator sends the current into the electrical conduit all the way to the production team house, so that the production team has electricity to use.

In the future, the production team will be able to use electric lights, loudspeakers, radios, telephones, etc.

Captain Gu and Accountant Liu also discussed that if any household wants to have electricity, they can report to the production team and pay a little money for the wire to get electricity to their home. From now on, they only need to pay a monthly electricity bill.

When the members heard this, they said, "Hey guys, we collect money from everywhere!"

If not, what kind of electric light should be installed? Not required!

They can go to the production team room to use electric lights!

Xia Mingshuang is looking forward to getting electricity, but the government won't provide it. It would be very convenient for her own production team to install a water pump and a small hydroelectric power station.

She paid 100 yuan to pull the wires to her home and asked Gu Yunshan to install several sockets.

In this way, when Gu Yunshan brings the electric fan back to her, she can have the fan blowing at home.

Electric lights and radios can also be used.

It was too inconvenient to have no electric lights. Even if we lighted two kerosene lamps, the brightness would be limited.

The third sister also wants to do some work at night, and the children also want to read, so how much trouble will it take for their eyes?

On the day of completion, Gu Yunshan specially took the time to come back and take a look.

In the past few days, technicians from the machinery factory came with two masters to help with the installation, and it was completed in less than a week.

It is not the busy farming season, so the members are not so nervous about going to work. They go to hoe the fields and weed every day. This year, they organized manpower to dredge and repair small ditches on the ground, divert water, and water the relatively dry plots.

The plots that do not need watering should also be dredged, and water can be diverted when needed, or used for drainage in years with heavy rainfall.

They were very curious when they saw technicians and masters building small hydropower stations there, and gathered around to watch if anything happened.

"Can this thing really generate electricity?"

"That's for sure. The light bulb will turn on when you plug it in. No need for kerosene."

"That would be great."

"It's also expensive. My relatives in the city said the electricity bill costs one yuan a month."

"Good guy, just one yuan a month? We don't dare to use it. We can't afford it!"

"It's okay, let's go to the team room to use the electric light."

In particular, the women rushed to tell each other that they must go to the team house to do needlework.

In the past, when those old men didn't have enough for anything after work, they would gather in the team room and chat about things. What a waste?

From now on, it must be given to them, at least equally shared by everyone, one room per person.

When the water turbine pumping station and hydropower station were built, all the members gathered around to watch the excitement.

In that scene, the streets were filled with thousands of people, all gathered at the dam.

They looked at the small dam where the water flowed and the water wheel pump kept rotating. Even if a leaf fell in, it would not be caught. Instead, it would continue to swirl and float with the water surface.

"It's amazing!"

The water wheel pump is connected to the generator so that the amount of water is enough to generate electricity.

After Gu Yunshan and the technician completed the test, he notified the power to be turned on and asked his family and team to pay attention.

For safety reasons, Gu Yunshan added a switch to the generator so that the water wheel pump and generator can be disassembled and started separately, and the switch can be controlled according to actual needs.

This way there will be no wastage.

As he closed the switch, the onlookers were surprised to find that the pipe containing the wires made a buzzing sound!

Several light bulbs installed nearby suddenly lit up!

"Ouch~ It's lit!"

"Amazing!"

“Can our village still generate its own electricity?”

"It's amazing! It's amazing to be literate! This is all the work of scientists!"

Accountant Liu took the opportunity to educate them, "Then you still won't let your children go to school?"

"Haha, accountant, that kid in our family is not a scientist. Yunshan is, and his kids are very smart, so they must be."

"Yes, especially Miaomiao, she is very good at studying. We must let her study hard!"

Xia Mingshuang had been waiting at the door. When she heard someone shouting that the power was on, she immediately went home and asked her third sister to turn on her own small electric switch.

Although the light came on silently, they seemed to hear a mysterious voice.

This is light!

Da Zhuang immediately asked Gu Nianjun: "Brother Nianjun, who invented electricity? Who invented the electric light?"

Gu Nianjun scratched his head: "The teacher didn't tell you?"

Erzhuang immediately said: "Brother Yuhui has told my father several times, why don't you pay attention to your studies at all?"

Gu Nianjun: "Huh? I thought class was the only thing that counts?"

Xia Mingshuang: "Okay, don't rush Nian Jun. Not many people in our village know who invented the electric light."

Over there, Lou Yuhui also heaved a sigh of relief, took the last step, raised his head and smiled at Miaomiao, "Okay."

Although they were fully prepared, they still made mistakes when they started. With the help of Gu Yunshan, they revised it several times and finally succeeded today!

Miaomiao laughed, "Brother Yuhui, you are so awesome, you made your own radio!"

Da Zhuang turned on the electricity, and Lou Yuhui turned the button to adjust the channel. After a burst of electric current, intermittent sounds came out, "Central People's Broadcasting Station, Central People's Broadcasting Station..."

"Ah, it worked!"

The kids jumped with excitement!

Xia Mingshuang looked at the lights on, the radio playing, and the happy smiling faces of the children. She and her third sister looked at each other and smiled.

Emma, ​​this is what happiness feels like.
