Seeing Mr. Fat returning excitedly, Yang Rui was about to get up and go home. At this time, McNeill came down from the attic. Because the factory has nothing to do recently, and the physics laboratory instrument hall has not led it. Yang Rui remembered that he knew electricity, so he asked him to help. At this time, the researchers were very broad and had some knowledge of electricity, magnetism, machinery, etc. He still did a good job after he came. Although there were many language barriers, there were still a few students in the physics and chemistry training institute that could understand some pidgin English.

It was so difficult to start, and then it was more coordinated. The battery was quickly made out. Although it was done in a simple and had no commercial value, it still needed to improve. This also made Yang Rui discover McNeill's new use, which was to work in the laboratory, and therefore added him a two-dollar salary, which made him more motivated now. He also moved some of the things he used to make light bulbs, and lived in the attic prepared by Yu Huizu for Yang Rui, and studied the topics given by Yang Rui day and night.

He said, "Boss, my research has made some progress and is very creative." He waved his hands and was very excited, "But you still have to look at some questions to see if there are any better suggestions." He said, taking Yang Rui upstairs. There was still a student in the attic figuring out something. When he saw Yang Rui coming up, he immediately put down his salute. These students lived in Shanghai and were very interested in the study of studying things. After joining the physics and chemistry training institute, he became more interested, especially now that there is a special laboratory, he is even more worried about eating and sleeping.

And they also heard a rumor: it was the chemical laboratory next door that made something that even foreigners did not have. The court had issued a document as a patent. Several gentlemen would buy foreigners' machines to build factories. At that time, those who helped in the chemical laboratory gave out ten yuan or twenty yuan bonuses. If there were bonuses, there would be no bonuses. This is not the point. The key is that they could make foreigners have nothing to do, which would be an indescribable stimulation for them.

So as soon as the physics laboratory was opened, several physics fanatics did research day and night. Of course, these studies were all small experiments that Yang Rui excerpted from the physics textbooks of middle school. Not long after, they made Vodar batteries, dry batteries, and sulfuric acid batteries. Although they were very simple things, everyone was very motivated. Although Yang Rui did not give them lectures, he was still very respected by them as an experiment designer.

Yang Rui nodded when he saw them bowing and signaled that they would continue to be busy. This was McNeil taking out a light bulb. Yang Rui didn't know what it meant. When he saw it, he found that it was not a light bulb. Then he understood it in his heart. This was an electronic tube. McNeil explained from the side: "Boss, I made this thing with the equipment used as an electric light. I found it very strange. When wiring is installed in a certain direction, it can be powered on. If the wiring is replaced, it will not be powered on, but I don't know what it is for. Is this a new type of light bulb?"

Yang Rui was overjoyed when he saw the electronic tube. This thing was amazing. He was the boss before the transistor. The electronics industry was not good. The former Soviet Union was said to have been using it until the 1970s and 1980s. He couldn't help laughing, patted his shoulder and said, "How did you complete the task D that I gave you last time? Is this thing used on that?"

McNeill saw the task D, pointed to the thing on the long table beside the window and said, "Where is it? It's just done today." Yang Rui went over and looked at the fixed electronic components, induction coils, electromagnets, handmade variable capacitors, spark gaps, dry batteries, electric rings, a wired telegraph key and powder detector, and then connected a antenna stretching on the roof with a wire. It was done in a regular manner. He was satisfied and asked, "Have you done actual experiments and how effective?"

McNeil shrugged and said, "Boss, I'm very sorry. These things have not been actually used since they were connected. I still don't understand what they can be used for." Yang Rui accepted his apology. Yang Rui could not force a light bulb to understand wireless telegraph. Moreover, according to history, wireless telegraph was invented at this time. He didn't know exactly what year it was. He only knew that Marconi and a Russian were working on this thing. Later, Marconi also opened a Marconi Telegraph company, which has always been very strong in the electronics field.

One of the two students next to him should have understood their English conversation. He blushed and hesitated for a while and said, "Sir, I tried it according to the plan." Yang Rui was interested and asked, "How did you try it? What are the results?"

The student saw Yang Rui asking questions and replied: "Connect them according to the drawings of the gentleman, and then press the key, and an arc will appear in the gap. After passing through the capacitor, the bell received here will ring, but..." Yang Rui quickly asked: "But what?"

"But that place," he said, pointing to the capacitor, "It's smoke here. I started to think it was a short circuit, but after checking, I didn't find any problem. I replaced it with a new capacitor, but the result was still like this. Later, I took out one of the batteries, and when I was doing the experiment, I didn't know what to do." After that, I took out a record sheet and handed it to Yang Rui.

Yang Rui took it and saw that the above was written clearly in the format and wrote the adjustments on it. However, he could not find the reason for the failure of the experiment. He nodded deeply and said, "You did a good job. We must record every experiment well. Just look for the reason. Now it seems that the capacitor is not good and the voltage is too high, so it is not good to reduce the battery. The reason is really because of the transformer. Adjust the coil to reduce the voltage and try to see if the capacitor will still burn it."

Yang Rui is actually a second knife, but he can still pretend to be a tutor in front of these students. According to the student's experimental records, the current or voltage is too strong, so the handmade capacitor was scrapped. As for whether it is because of the current or the voltage, he doesn't know, the second knife? Not to mention that the things in the middle school physics textbooks are very simple, but they are not simple, and he has long forgotten it for many years.

While the two students were adjusting the transformer coil, Yang Rui said to McNeil: "Wick, Experiment D is a very important task. Do you know the telegram?" Seeing him nodding, Yang Rui continued: "This is also a telegram, but it is a telegram that does not require wires."

After hearing this, McNeil looked surprised: "Oh, God, are you saying true? Boss." Suddenly he remembered something again and shouted, "Oh yes, yes, I know, I know... I heard about this thing when I was in the United States. It seemed that a European was studying this. They all said that he was crazy. How could he send a newspaper without a wire?" After he said that, he immediately thought that Yang Rui was the person who was about to do this experiment, so he immediately closed his mouth.

Yang Rui did not blame him, but he did not have much theory to tell him why wireless can also send newspapers, and could only speak from facts: "Didn't this experimental record record record this is a good thing? There is nothing impossible. As long as we spend our energy to continue experimenting, isn't the light bulb you made by Mr. Edison doing more than a thousand experiments?" Yang Rui felt that he was a relatively advanced design according to the design given in the book, especially now that electronic diodes are made, which requires more confidence than Marconi and others. They should still use the detector made of metal powder.

McNeil saw that what Yang Rui said was true. If wireless transmission is indeed feasible, then he would be happy to study this magical thing. Telegraph is an industry with very profitable profits. If there is no wire, there will be no huge investment in cables, and the profits will be even richer. Although wired and telegraphs are now operated by people and it is very likely to interfere with the establishment of the wireless telegraph network, if a wireless telegraph bureau cannot be established, selling wireless telegraph machines will be a reward and a rich business.

Yang Rui didn't know that McNeil was in YY, but he thought of the electron tube again and said, "Wick, we have to make this gadget better. According to what I said, add a gate inside and turn it into three poles. This thing is to use a radio telegraph. He can amplify the received signal instead of the powder detector, so that the transmission distance of the radio telegraph can be further. There is also that capacitor, the power that can withstand is too small. We also need to find a way to increase its bearing capacity. If the power is increased, the transmission distance of the radio waves will also increase." Yang Rui almost said all he knew about radio telegraph, and then he didn't know what to say.

McNeil recorded it carefully, saying that strengthening capacitors and adding new gates to glass management can be achieved: the capacitors can only be replaced by materials. Insulating paper was used before. It seems that the effect of these insulating papers is not very good, which is also the reason for the scrapping of capacitors. There is no problem with the metal being powered on. As long as there is a better insulating material, there will be better capacitances; and there is no problem with adding gates to vacuum glass tubes. Light bulbs are his old profession, but it takes time to do these things. And now it is Christmas in China, and the students are all back home. Now these two students cannot come the day after tomorrow. The person they will come back as soon as possible will have to be more than a week later. He has no assistant, but many things need the cooperation of two people.

While he was complaining, the two students had already made the transformer coil and signaled that they could start a new experiment. Yang Rui nodded. One of them pressed the key, and the electric bell of the machine received on the other side rang. McNeil stopped complaining and immediately rushed over and said, "Oh, God, it was successful! It's great." There was no problem with the capacitor this time and it has always been working normally, but Yang Rui knew that the current signal transmission distance must be much closer than the previous signal transmission. He was very excited and smiled when he saw them. This time it was successful, but the current wireless telegraph has basically no practical value, and it still takes time to improve. It seems that wireless telegraphs can be transmitted for thousands of kilometers, but only a dozen, and the usage distance is over a hundred kilometers, so it is worth it.

McNeill was constantly trying to make trouble with the simple telegraph machine, and used Moss password to send the newspaper, which made him very happy. Then he asked the student to bring the newspaper downstairs and then sent the newspaper again. After a while, the people below ran up to take a piece of paper to record the content of the newspaper, and then moved the newspaper to a student's house farther away. Half an hour later, he ran back angrily and said, shouting excitedly: "I received it."

After hearing this, Yang Rui just smiled and was always excited to invent something new through his own hands. He ignored this and started drawing a picture - in fact, it was just drawing an ore radio. Although he didn't know how to make headphones, the overall circuit diagram was found in physics textbooks. In the wireless industry, in addition to telegraph services, there is also a good thing that can make a lot of money. Radio radio is expensive, but you can't buy it for everyone. This ore radio can be bought by every company. The example of MSG made Yang Rui understand that the real money-making industry is actually daily necessities. Today, when technology has not yet been fully popular, high technology cannot bring high profits. Only everyone uses it, and achieving monopoly is a real big profit player.

McNeil was already addicted to playing this. He even suggested that Yang Rui invite his friend Harry from the United States. Harry was an engineer at the light bulb factory he had studied in college and was very good at electricity and magnetism. It was said that he had also studied wireless telegraphs before. If he joined, the research would progress faster. He can't wait to conduct in-depth research on this magical telegraph in anticipation of the day when it could be practical. Yang Rui agreed to give him the right to select people, but asked those who came to be professional, and if they were not professional, it would not be helpful. McNeil patted his chest and said, "Boss, I swear in the name of God that the people I found can definitely advance this research."
