People like to be clean and tidy, so that people can feel comfortable, if all kinds of messy parts and wires, all piled up in front of you, you will feel uncomfortable to look at, so making a box that can hold all the scattered parts, has become a must.

For the requirements of the box, there are mainly so many aspects, one is that it must be able to accommodate all the parts, in addition to the telemechanical keys and headphones, these two parts do not need to be loaded into the box, the rest of the components should be all loaded into the box, the second is that all the parts are loaded into the box, to be able to use normally, but also to facilitate disassembly and maintenance, if it is loaded, due to the mutual interference of the parts and components to cause the reduction of stability, then there are some gains outweigh the losses, and the materials and workmanship of the box should also be exquisite, Even carving some delicate patterns on the surface is necessary.

After all, in the Tang Empire, this thing is a very rare thing, very expensive, ordinary people can't have it, and since it's for the powerful, it naturally has to be a little exquisite, if the appearance is too ugly, it's not good, it should be made a little more exquisite, so that it can match the residence of the powerful enough, and even become a very high-grade furniture.

After lunch, Ang Lee and the technical personnel conducted a series of experiments, no accident at all, the experiment was very successful, which is enough to prove that the machine is very reliable and fully usable, so there is only one last step left, that is, quickly prepare the box, put all these messy parts into the box, and then you can take out the finished product to the emperor to see.

In fact, the box has been prepared for a long time, but because it is not yet certain, what are the final parts, what is the specific size, so, in order to avoid not being able to fit, the box is made relatively large, just like the sedan chair of the sitting, and the handles are also installed on both sides, which can easily be carried like a sedan chair, and the box is carried away to facilitate movement.

Because there are only two machines that have just begun to be studied, the box is also made of two, and the material for making the box is wood, and it is also a very precious rosewood, the surface is coiled, the carving is also more exquisite, there are all kinds of Rui beasts, as well as beautiful flowers and trees, in short, no matter how you look at it, it is a very high-grade furniture.

Since the size of the box is large enough, put all kinds of parts into it, naturally there is no pressure, and it can also be put very loosely, so, it is still very good for the heat dissipation of the machine itself, if the box design is too small, it will cause poor heat dissipation inside the box, so, it is not good.

The heat of the telegraph is actually not very large, however, in the summer, even if the heat is not very large, the temperature inside the case is enough to choke, so it is good to be as spacious as possible, besides, the bigger the more it can appear imposing, in addition to the people who know it, the average person will not open the box to see, so, you will feel that the things in the box are very mysterious, and virtually improve the grade of the transmitter.

"Li Shilang, it's been more than an hour in a row, and there is no glitch at all, the telegram experiment should be considered a success!"

The craftsman reminded.

"Well, it's really good, by the way, stop the experiment for the time being, lift the two boxes out, load the machine into the boxes, and then test it again to see if it's still reliable, and besides, this time the experiment will go on forever, and someone will continue to conduct the instruction experiment at night to see how it works if you stick to it all night?"

Li An opened his mouth to ask.

"Yes, let's get ready."

The craftsman took the order, according to Li An's requirements, all the parts of the telegraph machine were fixed in the box, and because the area of the box was too large, the installation process was very smooth, each part had enough space, and the connecting lines everywhere were also well organized.

The transmitter electromechanical keys and headphones are also designed by Ang Lee himself, which is much larger than that of later generations, and there are many patterns carved on it, although it is not necessary, but in order to highlight the extravagance, it is also necessary to carve some, who let Ang Lee invent this thing to serve the aristocracy?

"Li Shilang, everything has been done, all of them have been packed into the box, and they have all been carefully checked, there will be no problems."

Craftsman happy report.

"Then what are you waiting for, hurry up and start the experiment!"

Li An anxiously urged.

The craftsmen hurriedly started to work, constantly sending instructions to each other to verify the reliability of the machine, but the only dozen or so senders were tired enough, however, they were also very excited, at the beginning, when Li An taught them, they still felt quite boring, and now they see that their instructions can be transmitted, not to mention how happy they are.

As long as this machine can be popularized and applied on a large scale, then this kind of talent will be cultivated on a large scale, and the current training of this bit of manpower is too small and far from enough.

Half an hour passed quickly, and the telegraph did not have the slightest malfunction, which made Li An quite satisfied, which showed that putting these parts into the box did not have the slightest impact on use, and then, it could be carried into the palace for the emperor to admire.

"Very good, you have done a good job, this experiment is considered a success, tomorrow, you can enter the palace to experiment, however, you still can't rest, from now on you have to keep experimenting, you can't stop for a moment, tomorrow when the Japanese official comes, tell the official the results of the experiment."

Li An said.

Although the experiment has been successful, and there has not been the slightest failure for a long time, the time of the experiment is still not long enough, and it must be able to withstand the test for a long time in order to reassure Ang Lee, and the longer the trouble-free time, the more the quality and reliability of the transmitter can be reflected.

After explaining everything, Li An went back, and Li An was tired enough this whole day, and he had to go back and have a good rest.

The development of the telegraph, is the need for wire connection, not wireless, this has to be said to be a pity, after all, the value of the telegraph is that it can transmit the message to a very far place, the farther the transmission the greater the value, but under wired conditions, the farther it spreads, it means that the longer the wire is needed, the higher the cost, if you can develop a radio, it would be the best.

As long as the radio is done well, the propagation distance is also very far, and the radio propagation path, there are three main ways, one is the sky wave, which uses the reflection of the ionosphere to transmit the battery wave, also known as the medium wave transmission, the second is the ground wave, which is propagated along the ground, also called long wave transmission, and the third is the linear wave transmission, which relies on a large number of relay stations along the way to relay.

Among them, the transmission ability of long waves is very strong, because it is propagated close to the ground and can pass through obstacles, so it can transmit electromagnetic waves to hundreds of miles, or even thousands of kilometers away, but if you want to achieve global communication, you still need the help of relay stations, otherwise, it is impossible to complete this task.

Of course, there is a fourth, more powerful way of propagation, that is, satellite relay propagation, which is much stronger than the relay station on the ground, after all, the satellite is suspended in the air and can have a wider radiation range, much higher than the ordinary relay station on the ground.

The high-tech content of the satellite thing is too high, I dare not think about it, but it is still possible to consider making a radio, and this will be done later, and now we only need to improve the wired telegraph.

"Husband, why are you so happy today, from the moment you enter the door, you will be full of spring breeze."

Yan Ruyu saw Li An coming back, walked over and asked.

Naturally, Ang Li would not hide anything, and hurriedly told the truth about the matter.

"Oh, my husband succeeded, it's really good, can you really spread the news thousands of miles away?"

Yan Ruyu was naturally happy.

"This is nature, the ability of the husband, don't you know? I will enter the palace early tomorrow morning, tell Your Majesty the good news, and show it to Your Majesty in person. ”

Li An said happily.

"Your Majesty will definitely reward your husband greatly, so that tomorrow's New Year's goods, my husband is afraid that he won't be able to catch up."

Yan Ruyu said with a little regret.

The so-called New Year's gift is that every year before the Chinese New Year, Ang Lee will personally bring a large number of New Year's gifts, go to the homes of various craftsmen, and give these gifts to these craftsmen to commend their hard work in the past year and ask them to continue to work for themselves in the coming year.

Although Li An's salary for these craftsmen is already very high, there is no need to send additional New Year's goods, but these craftsmen are all skilled workers, they are all fragrant and sweet in Li An's eyes, the loss of any one person is a huge loss for Li An, in order to warm people's hearts, Li Ang still decided to do this, and, as long as he is free, he will personally go door-to-door to give gifts, if he has no free time, several ladies and servants will also do it for him, although it is okay to find someone to give gifts, But sending it in person can show more respect for these craftsmen, and in the years that Ang Lee has gone south, Yan Ruyu has replaced herself, and will personally go to the homes of various craftsmen every year to deliver New Year's goods, and this year is naturally no exception.

Once encountered bad weather, and there was a delay in the family, Yan Ruyu naturally couldn't finish it alone, so the rest of the ladies also came to help, everyone went to give gifts, and finally before the New Year, all the New Year's goods were delivered to the hands of craftsmen.

To say that this delivery should not take a long time, but there are many craftsmen in the workshop under Li An, and there are hundreds of high-tech craftsmen who are worthy of respect, and they will not live in the same place, some live in the east of the city, some are in the west of the city, and there are many in the south and north of the city. Say more polite words, stay for dinner naturally will not, but a cup of tea or a glass of wine is still necessary, in this way, each send a family is to delay some time, a moment or two of time delay is necessary, an hour of time can send five or six is good, a day to send six hours, but only more than thirty, so, it can be seen that the time to send New Year's goods is still very tight, in case the time is too late, the next class craftsman can only let the senior servant personally give gifts.

Fortunately, the craftsmen will understand Ang Lee's and will not care too much, as long as the people Ang Lee visits are indeed more capable than themselves, they will be convinced.

"It's okay, the demonstration should be completed tomorrow morning, and it will be fine in the afternoon, even if Your Majesty wants to hold a banquet to celebrate, it will be after dark, Madame will go to deliver New Year's goods first, and when the husband rushes back, he will go with Madame."

Li An said.

"If the husband and the gentleman go in person, the craftsmen will be more encouraged, by the way, the tenants' New Year's goods will be sent more, I asked a few sisters to send them, I can't be busy, so let Wang Ba also go to help."

Yan Ruyu said.

"Okay, Madame has decided, the tenant has no skills, even if he doesn't deliver it himself, it's nothing, it's far less important than the craftsman, the glass workshop for the husband, still count on these old craftsmen? These people are not slacking off, and as long as they are energetic, we will have endless treasures of gold and silver. ”

Li An said proudly.

It's not that you're selfish, people are selfish, respect also depends on who the other party is, under the premise of limited energy, it is natural to give priority to people who are useful to you, and for people who are not important, you can put it aside first.

Although he has gone home, the news of the experimental progress of the R&D center will continue to come back, which Li Ang has arranged a long time ago, in order to reassure himself.

Fortunately, before the rest, the R&D center came back with good news, and there was no news that made Li An unhappy and did not want to hear it.

Early the next morning, Li An got up very early, and after eating a little food, he was ready to rush to the palace, where the talents of the two newly developed telegraph machines and the R&D center would wait for Li An at the gate of the palace, which Li An had already arranged.

"Husband, it's time for us to go."

Yan Ruyu and the others also carried a large number of New Year's goods, ready to be sent to the craftsmen and tenants who needed them.

"Okay, everyone has set off, and the husband has gone to the palace, and you are all busy with your own business.

After Li An finished speaking, he took the car to the palace, because he was in a very good mood, and the scenery along the way seemed to be different from usual, and they all looked so beautiful, which made Li An feel even better.
