Thanks to book friends: the bitter sea has no boat and laughs and forgets the enthusiasm of the reward.

(Today's situation is a bit special, so the update time is late, the second shift will be after 12 o'clock, everyone doesn't have to wait, rest early, and I'll see you early tomorrow morning.) )

After lunch, Ah Xiu bamboo basket brought a bowl of food to Yang Cheng, and at the same time went to replace Yang Cheng.

The child's personality is relatively wild, so if Yang Cheng has been guarding it, how can he rest assured.

Ah Xiu was fine in the afternoon, so she let Yang Cheng go to play, and she borrowed a stool from next door and sat next to her.

Li Chu was next to the yard, using wooden nails to piece together the planks of the waterwheel one by one, considering the flood season of the river, this waterwheel is relatively large.

Originally, according to Ah Xiu's meaning, since he had made a waterwheel, he would add something to bring the river water over.

The reason is that Ah Xiu saw such a water wheel in a landlord's house in Xiangcheng County, which is very convenient to run and can irrigate river water to the fields, but the carpenter Li in the village will not do this, she didn't expect Li Chu to do such delicate carpentry work.

What Ah Xiu said is the waterwheel that is serious.

Li Chu did this, not to build a waterwheel, but to rotate the waterwheel through the river and play the role of a rotor.

Although there was no pollution in ancient times, and the river water was clear, as a person who came through in later generations, he still chose a nearby well compared to drinking water.

After wasting most of the time and effort, Li Chu's waterwheel was finally successfully assembled.

Spread flat on the ground, the diameter reached more than six meters, which was a bit big, and Li Chu couldn't transport it to the river alone.

The bank that Li Chu chose was more than one meter above the water, and the water surface was at least three meters from the bottom of the water, because the bamboo pole used for measurement was only so long, and the six-meter-large waterwheel was enough.

To install the waterwheel on the river, you have to ask someone to help.

Li Chu went to the village again and invited ten young and strong helpers at a salary of 80 yuan a day per person.

"Xiao Chu, what you say, we will listen to you."

Li Chu's courtyard also belongs to this village in principle, but it is not built in the gathering place in the center of the village, and some of these ten people are older than Li Chu, and some are smaller than Li Chu, but they are all long and sturdy, and they are powerful masters at a glance.

The leader is an uncle Li in his thirties, named Li Han, with a beard and a fierce face, which looks a bit like Zhang Fei and Li Kui, but his inner personality is diametrically opposite, very gentle, and he doesn't care if everyone jokes about it.

Because Li Hanneng often found work for the big guys in the county, this time and again, the young and strong people in the village were all headed by Uncle Li.

The big guy looked at Li Chu with a smile on his face, because Li Chu's salary was higher than that of others.

"With eight people, help me carry this to the river first."

Li Chu pointed to the assembled waterwheel on the ground and pointed out the destination to Li Han.

"Then come and come with me to the woods and cut down some trees."

The timber was sufficient, but it was only used to support the pillars of the waterwheel, and it was necessary to cut it down in the forest temporarily. You don't need any big wood, just take a fist-thick trunk, and no one will say anything if you cut down a few.

Each of the three men carried a few tree trunks to the riverbank.

"I didn't expect Xiao Chu to work as a carpenter."

Li Han's group also recognized that this was a waterwheel, Li Chu nodded, and then assigned people to fix the beam frame of the waterwheel according to his guidance, and two people who knew how to water got into it and fixed it with a grasping nail.

Considering the cold water of the river in this winter, Li Chu raised the wages of each of the two people who went into the water by 30 wen.

The foundation is stable, and the big guys work together to erect the waterwheel and install it.

When doing things here, Li Chu was on the side, looking at these ten people seriously, because he had the residual memories of his predecessor, he still had a deep understanding of this Li Han, and if he carried out it according to his own plan, this Li Han in front of him was a good talent.

In addition to Li Han, the remaining nine people, when they see them working, they are also serious, and no one is lazy and slippery, and they can also be used.

Li Chu secretly memorized the names and appearances of these nine people in his heart.

The watermill is set up!

Li Chu climbed up and checked it carefully, and made sure that there was no problem, so he let go of the clip, and the waterwheel also turned with the flow of the river.

Then Li Chu ran to the side again, carefully observing whether the fixed angle of the shelf was tilted.

Hmm, it's not tilted, it's just right.

This waterwheel is also a laborious job, and in this winter, everyone's faces are sweating.

In order to prevent waterproofing, it was necessary to build a small house to store the power generation equipment.

Li Chu asked everyone to pick some gravel over, and asked Uncle Zheng from the folk kiln to send a batch of adobe bricks over, and then on the bank of the river, a small house was built with adobe bricks, and the size of the house was high and wide, all according to the standards provided by Li Chu.

While building the house, Li Chu also mixed cement and sand and gravel on the side, and made several large cement slabs on the ground.

He doesn't know how to get a cement roof, and there are too many doorways and doorways with steel bars inside, so he simply uses cement slabs instead.

It will take another day or two for the cement to dry, and after the construction of the roofless house is completed, Li Chu will pay everyone one by one.

Later, it involves the process of the generator, purely by brainpower, and there is no need for manpower, Li Chu asked Li Han and them to go back to the village first, and there will be a place where he is needed in a few days.

The principle of power generation is that the rotor cuts the magnetic field to produce electrons.

Magnet power generation is the simplest one, but this limitation is too small, and the voltage voltage of the generated electricity is too small.

In this regard, Li Chu has his own solution, which is to customize two super large magnets to the custom system.

This hut is used to put magnets.

But before that, he had to get the rotor right.

Use a straight tree to stuff it from the opening of the waterwheel, connect the rotating power of the waterwheel, and the wooden pole is inserted into the hut at one end, stuck in the middle of the two magnets, and then make a clip at the head of the trunk to fix the stuck rotating copper rod.

Turning the copper rod, which is also customized to the system, with the blacksmith technology of the Northern Song Dynasty, it cannot be created so stable and uniform. It also needs to be bent.

First bend 2 90 degrees inside, then 2 90 degrees outside, this bend is not the same place, but every few meters to bend, and finally make a tennis racket, or ****** style shelf.

(This is not easy to describe, you can Baidu under the principle of the generator, you will know what shape it is.) ）

The middle position of the finished copper rod shelf is fixed on the straight wooden pole that extends into the house of the waterwheel.

At the other end of the copper rod shelf, two wires are connected, and then one wire is added from the middle of the two wires.

The wires are all purchased from the customized system, and it is precisely because of the customized system that Li Chu has the confidence to dare to make this generator, and at the same time, Li Chu also understands one thing.

Customized systems have high price restrictions in terms of technological barriers.

However, not including the technology in your head.

Like this kind of generator, directly from the custom system custom purchase, will make the first generator purchase price at a very high price due to technological barriers.

However, if you only buy some parts of the generator and assemble it yourself, you only need to pay a very low price for the materials.

Once you've connected the wires, you'll need one more item.

The role of the ballast is to stabilize the current, stabilize the current and voltage.

Connect the two wires that are added to the ballast, and then connect two wires from the ballast, and these two wires are directly connected to the wires used at home.

To this end, Li Chu also deliberately cut down more than ten long bamboos, opened the bamboo inside, and passed the wires through the bamboo, which was to protect the wires from water through the bamboo joints, and then support the bamboo poles on them at intervals, away from a support point.

By the time Li Chu connected the wires into the small courtyard, the sky outside was gradually getting dusk.

Ah Xiu is back, and there is nothing to go out in the town at this time, so there is no need to guard it anymore.

Yang Cheng, Yang Kang, and A Ning stared at Li Chu curiously in the courtyard.

Because Li Chu just said that he wanted to make them a super big and super awesome magic.

After connecting the wires to the house, in the main hall, Li Chu installed a main switch switch, and then divided several follow-up wires, one to the east wing, one to the west wing, and one outside the main hall for lighting the courtyard.

In the main hall, another one was divided into the main room.

In each hall, Li Chu installed a closed-circuit switch, which was the kind of switch used to turn on the lights in the house in later generations.

Once the wires are in place, it's time to install the bulbs.

The price of light bulbs is also cheap, one custom coin, incandescent lamps in later generations, you can order ten.

One was installed in each room, and in the east wing, considering that Yang Kang likes to read, he installed another one on the wall, and then added a table here as a desk lamp in the future.

The lights in the yard are lit with bulbs with a higher wattage.

Ah Xiu looked left and right in the courtyard, and then looked, Li Chu kept them secret, and she didn't know what these things were used for a while, but looking at the appearance and delicacy of these things, she felt that they were heavenly things.

Because Li Chu told her that in the past two days, he had sleepwalked in heaven several times before and after, and the public loser gave him a lot of things.

After everything in the yard was done, the sky outside had already begun to get dark.

Walking outside the yard, some objects can no longer be seen clearly, only some vague shapes can be seen.

Li Chu arrived at the bank of the river and stood outside this hut, quite embarrassed.

The first generator in the Northern Song Dynasty is about to be interviewed.

Li Chu called out two magnets from the space and put them into this hut, and due to the difference between the two magnets, a magnetic field was instantly generated.

Then Li Chu walked to the waterwheel and released the clip of the waterwheel.

The water carries the waterwheel to rotate, and the waterwheel also drives the copper rod frame as the rotor to rotate.

The copper rod shelf rotates in the magnetic field, cutting the magnetic field, cutting the magnetic field into countless electrons, and then the electrons are transmitted to the wire through the copper rod.

The wires were then passed to the ballast, and the working light of the ballast was lit......
