Yang Heng's so-called wired telegraph may be the simplest wired telegraph equipment. In terms of hardware, it consists of four parts: generator, wire, transmitter and receiver.

That's right, it's that simple. Morse code is a little more complicated. That is to say, the code here is a code composed of a short dot and a short dot, two short dots and intermittent dots. They are also four digits, and each set of numbers represents a specific Chinese character. Why is there no long dot? This is because there is no amplification device, so you have to use two consecutive short dots instead of long dots. One short dot represents zero, and the two short dots represent one. And this is still a hexadecimal encoding method. Although it is a bit more complicated, it is impossible to transmit messages from a distance, but it is a bit troublesome to translate, and even as a transceiver, you have to go through rigorous training.

This time, Yang Heng did not stay in seclusion for too long. He just thought about it for a day in the room, drew a few drawings and it came out.

"Butler, you arrange someone to find Yang Li, and Yang Lilai will be responsible for this matter." Who is Yang Li? The younger lady's brother Dandan, his big name is Yang Li. He is already seventeen years old this year and can also stand alone. He is more interested in mathematics, but he is aware of other knowledge. Even if he continues to study in academy, he will not have any great prospects. Therefore, Yang Heng will start to arrange their jobs for these little brothers one by one. In the officialdom, those who are interested need to enter, otherwise there will be a special profession for them.

When someone informed Yang Li, Yang Heng was not idle either. He was studying the matter of drawing wire with some jewelry copper smiths. That is, pulling out the copper wire. Moreover, it requires various types of silk. At this time, Yang Heng had to admire the masters of this era. Their skills were really amazing. They could not only pull out thick copper wire, but also pull out thin wires with thicknesses of hair. In this way, another thing of Yang Heng's problem was solved, that is, the matter of enameled wire or silk wire can be solved. Some thick copper wires can be wrapped with silk or brushed with tung oil outside. In this way, some copper wires used for experiments will be available, and then the masters will study how to form the production of industrial words. You must know that if these things are really used, they are not simply one meter or two meters, but will be used in large quantities.

"Brother, you call me. Finally, I have something to leave to me for it." Yang Li ran over excitedly. As soon as he received the butler's notification, he was excited and trotted all the way, without even a single stutter.

Yes, all along, the little girl was able to help Yang Heng, but they were always tied to the academy by Yang Heng, who would help him during the party, and the others were gone. They were also anxious to see Yang Heng being so busy with this family. If you have the deepest experience, it was these little friends. They enjoyed the days they suffered in person, and they knew how this good day came about. To be honest, they were extremely grateful to Yang Heng, so they all had to study hard and help Yang Heng.

Finally, Yang Li began to prepare for something to do.

"Well, there is something wrong, but you have to go back to the academy. Come on, listen to me first, listen, Didi, dri, dri, dri, this represents one,000, this is the representation of hexadecimal. If it becomes decimal, it represents the number eight..." Yang Li is worthy of being a child who is more interested in numbers. After Yang Heng explained it to him several times, he understood the mutual conversion between the decimal and hexadecimal. Even the six numbers ten to fifteen were replaced by abcde, and Yang Heng only stopped there, just taught five more letters.

"Your task now is to use these codes to compile the Thousand Character text into the Thousand Character text, and then slowly add some other characters, but you won't be in a hurry for the other characters. After you go back to the academy, you mainly organize a coding team. This is your temporary main task. After the Thousand Character text is completed, you will assign a deputy team leader, and you will need to assist me, and you will even be responsible for this wired telegraph project in the future."

"No, brother, Dandan will definitely complete the task." As he said that, he turned around and wanted to leave. "Don't worry, since he is back, let's play at home for a few days first, and then follow the brother to learn about the process of this work." Yang Heng naturally would not let Dandan continue running back immediately. If he didn't know anything, how would his future work be carried out.

"Brother, this is the generator. What does the generator do?" As he said that, he was about to touch the thread. "Don't touch it, it will be dead." Yang Heng nervously pulled the balls away, then wrapped two bamboo sticks around the threads and touched each other, "Look, this is the spark, it is caused by the electricity emitted. With just this touch, the copper burned."

However, there is no voltmeter or ammeter at this time. Yang Heng didn't know the voltage, so he would just not touch it. Isn't there any glue? People who come into contact with this wire and telegraph will make them a pair of gloves and a pair of boots, mainly for insulation. In addition, they are all paved with wooden boards in the workplace, so that the insulation level will be even higher.

If we talk about how this generator is made, Yang Heng naturally made a permanent magnet generator. Whether it is a self-exciting generator or a recharger, it requires a rectifier. Then we can only use a permanent magnet generator, that is, the stator is made of natural magnets. Needless to say, this effect is great. No matter how sparks are used as electric welding, there is also this power, it is naturally driven by a water truck, and there may be a wind turbine. No matter what the battery needs to be studied, suddenly, Yang Heng discovered that with this generator, it seems that there is more things to do. Should we ask Li Er to have a job in the Ministry of Industry, and we don’t need to go out again in the future. We can study some things at home. If it is not very important, we can hand it over to Li Er.

Dandan left with a cheerful mood, while Yang Heng was starting to make headphones. What does this headphone look like? It is the most primitive high-resistance headphones, and it is relatively bulky. A very large iron block is wrapped with thin enameled wire, and then a wood shell is used, and the moving piece is made of a round thin iron piece, but this needs to be tested, otherwise it will not make a sound.

"Your Majesty, today I have brought you a new thing. I wonder if you are interested in experimenting?" "Just this, what is this?" "This is a generator, but not only this, I also need to apply to build a wire in the palace." "Oh, what is a wire?" "With a wire, that, that's this thing," Yang Heng took out a piece of wire with skin, "This, it's done, just pull it."

"I said to learn literature, why are you leaving? You don't want to pull the wire?" Li Er suddenly found that the Yang family turned around and left. "Well, Your Majesty, pulling wires is quite troublesome. You have to bury electric poles and what else you need. It takes two days. You'd better send a palace guard or someone else to follow along the way." Suddenly, Yang Heng thought that although Li Er had agreed, he had no order and he left a little hastily.

…………

"What's the use of this?" Finally, Yang Heng pulled the wire from his home in the city to the palace, but the place in the palace was placed in a place with a river. Why? Water trucks and generators can be set up in this place. However, this time Yang Heng brought one more person, and this person was a telegrapher from Yang Lizhao.

"Your Majesty, you can say a word, and then someone from my family will be delivered quickly, and the reply from the family will be known quickly."

"Oh, so magical?" Li Er was a little interested. Why could he agree to Yang Heng pull the wires into the palace? He just wanted to see what Yang Heng had made again.

"What should I say? Then ask who the other party is, who are you, how old you are this year, and there is another saying, "The world is so yellow, so many." At this time, I found that the telegrapher was wearing that huge and ugly headphones, and then I started to press it on my hand. Didi, what a familiar sound.

"I am Yang Li, I'm sixteenth this year." The answer is very simple, but Li Er did not respond. Who knows who is opposite? Maybe it was made up by this Didi person.

"Your Majesty, the horse outside is coming." "Hurry, hurry up, bring the note in." Li Er was anxious. "Who are you? How old are you this year? There is another saying, "The world is so yellow, so much." The reply is that I am Yang Li, and it's sixteenth this year."

"This, this is the wind, how did you do it, how far can this thing be used?" Li Er was shocked. If this could be spread far, what would it be? (To be continued...)
