"Are you?" Finally, Yang Heng discovered the work of these jewelry technicians.

"Alang, we wanted to give you a surprise, but we actually got stuck in this place, the pointer could turn, and even the scale was very accurate, but the speed was not very stable."

Yang Heng carefully observed the clock they made. He found that the components of the clock were very reasonable, and all the gears were made of brass. In this regard, they were considered qualified. They also knew that the brass was the most wear-resistant, and the gear ratio was also very reasonable, and even the number of turns of the pointer was quite reasonable.

Their idea is to turn around during the day and at night. This is two circles, the same as the clocks in the previous life. One circle is twelve hours and six hours. Although the same time day and night are as long as there are not a few days in a year, they designed this way, and the minute hand, but the rotation of the minute hand is different from the minute hand in Yang Heng's previous life. The minute hand they designed is to turn around for an hour, that is, two hours. In other words, on this day and one night, the minute hand is to turn twelve circles, and the second hand is designed with sixty circles as one third of the monument.

"Your design is basically reasonable. Have you ever thought about this big clock? By the way, I call it a clock or a clock. Do you think that this fast-paced needle will make it jump for a second? This second means, let's put it this way, in half an hour, we can design it as an hour, and one hour is divided into sixty portions, so how about one portion, and one minute is divided into sixty portions. One portion is one second. You can divide the time according to this calculation method. Would it be better? After you have made this correct, we will study other aspects."

If you want to talk about why Yang Heng divided this way, it was because he used to the distribution in his previous life. This is why he divided this way. Another thing is that these technicians have divided the time of day into two circles, so it is also necessary to divide this way. Originally, Yang Heng wanted to design the twelve hours a day into one circle.

"Come on, look at my voltmeter." After they transformed, Yang Heng brought a voltmeter, and it was a voltmeter with zero position in the middle. Yang Heng even took off all the glass on the surface.

"Look, can you tell anything?" As he said that, Yang Heng pulled the needle to the end with his hand, and then the needle swung back and forth.

"It can swing for a long time." "Well, it's not bad. This is one aspect, what about it?" "And, it seems that the swing frequency is the same, is it that meaning?" After observing for a long time, they finally made such a judgment.

"You all know the structure here?" "I know, we have all participated in the manufacturing, there are two hairsprings and dynamic coils here, you have explained them to us."

"Then, you said, if we add such a hairspring to the clock and an escapement, the working principle of this escapement is like this. It needs to be synthesized with an escapement gear hairspring, three parts, what do you think?"

After Yang Heng's prompt, these technicians finally understood that soon, an escapement, gear, and hairspring were made. Sure enough, the pointer began to move at a constant speed.

"Alang, this pointer can really turn at a constant speed, but the time cannot be adjusted. This one hour is much different from the standard one hour."

"You can study the gossip again to see what the difference is between the length and the swing speed of the gossip."

"Alang, it turns out that this is how it looks. Adjusting the length of the hairspring can adjust the speed. Haha, it's great, this clock can finally be adjusted accurately."

"You said, if this clock is added with a pendulum, will it look better?" Since the prototype of the clock has come out, it needs to be considered practically. At the moment, Yang Heng does not intend to add the clockwork to this. This is not too anxious, and it is also possible to use a heavy hammer as power. The clockwork is different and it needs to be turned on. Now it is a large clock. Naturally, this spring is still not needed.

"Your Majesty, should you build a bell tower in Chang'an City?" Since it was built, it needs to be sold, especially the first clock was actually a giant clock, so this thing can only be used to build a bell tower, and the place where the bell tower is needed is Chang'an City. So, Yang Heng asked Li Er to sell it.

"Clock Tower, what is a clock tower?" "Clock Tower is just a building that counts time. During the day, people can directly see the time, and even at hourly time, they can use the bell to report the time. At night, they can directly use the bell to report the time. However, if the light is added, they can also look at the time. However, at night, they need to be seen from close range. During the day, they can be seen by everyone in the city."

"I heard what you said, that's definitely a good thing. Is this clock accurate?" "Accurate, I have already tried it. After five days of testing, it won't be a second away."

"Where do you need to place this bell tower? How high do you need to place it?" "This, Your Majesty, look, how about it in the middle of Zhuque Street? It's okay to be five meters high, but you still need to consult Master Yuan. I wonder if there is any statement about Feng Shui?"

"No need to ask for the advice of the old Taoist. The old Taoist agreed. It should be good to set up such a bell tower in the middle of Chang'an City." Yuan Tiangang actually walked in from outside at this time. "Well, Master Yuan, how do you know about this?" "Ha, didn't your clock be put in home and set it up? I've seen it before, and I know you came to Your Majesty, so I'll hurry up and you've finished talking." If you want to say, it's Yuan Tiangang, who entered the palace during the day, basically you can come in directly without reporting.

A few days later, just before the Spring Festival in the 12th year of Zhenguan, a bell tower stood up in the middle of Zhuque Street.

"Ding Ding Ding Ding Ding..." The calm and powerful bell finally rang over the Tang Dynasty. So, a profession was officially laid off, that is, hitting the Geng people. Originally, every night, the people who hit the Geng would call the gong every other hour, but after the bell, they became unemployed. However, not all of them were unemployed. There were still several people who needed to be on duty in the bell tower. Whenever the heavy hammer fell, they would shake the heavy hammer to the top to prevent the clock from stopping. Some of them turned directly into night-time visits and patrolled with Wuhou. Yang Heng did not want some people to be unemployed because of his reasons.

When building the bell tower, Yang Heng did not let the copper smiths be idle, but asked them to reduce the components of this giant clock according to the proportion. In this way, the clocks used for households were officially developed. However, these clocks are also heavy hammer powered. In order to make money, Yang Heng used all kinds of methods. Now he used heavy hammers. After a while, he would change the heavy hammers to a spring spring. In this way, some families would buy two clocks, and then, the pocket watches that could be carried with them, and then the next one is the pocket watch that can be worn.

Watches are a process of gradual improvement and a process of continuous making money. If watches begin to become popular, then diamonds need to be placed in place. After diamonds are placed in place, some high-end, atmospheric and high-end watches, or even gold watches, Yang Heng’s purpose is to put some money from wealthy families into his own pockets. Only by putting them in his own pockets can he be used well. Otherwise, this money can only rust and mold in some families, waiting to have children, but it will not be born yet, right? It will only rust.

In other words, the Yang family has a factory that can make money and starts to be built again. Suddenly, Yang Heng found that there were too many factories in his home and too complicated. Otherwise, he could abandon some factories, or these factories could be auctioned for a good price. (To be continued...)
