As we all know, the thickness of a thin piece of paper that is folded a hundred times in half will exceed the distance between the earth and the sun! This is the effect of superposition.

If a very, very thin hammer head is used and the hardness is sufficient, then an ordinary person can easily break the anti-explosion glass. This is the principle that the ratio of pressure to the area of ​​the force is pressure. 100 Newton force and the area of ​​the force is 0.001 square meters, then a pressure of one hundred thousand Pa will be generated, which will be very terrifying.

By the same token, if a small No. 5 battery releases electricity in a very short time, it will also generate huge energy, which can easily knock an adult out.

What Liu Meng has to do is this device. The principle itself is not complicated, and it does not even require electronic control. It can be realized by analog circuits. It is just a high-voltage pulse discharge.

Simply put, it is just a high-voltage pulse power supply.

Liu Meng is fully mastered in series resonance technology. During his studies, he was responsible for the development of a number of high-voltage DC power supplies. At that time, there was a project for developing electronic computer X-ray tomography equipment in a hospital.

Since this device has great radiation, the key point is to develop a high-voltage DC power supply device that boosts from zero to 160kV within 0.5ms, and excites X-rays for tomography.

To him, making a micro high-voltage pulse discharge device is like killing a chicken. However, Huang Sheng's laboratory itself is an electronics laboratory and belongs to the weak current category. Some commonly used power conversion devices do not, which is a restrictive factor.

Especially for making high-voltage pulse discharge devices, the two step-up transformers are needed, and there are no ready-made materials in the electronics laboratory.

The No. 5 battery has a voltage of only 1.5V and a power capacity of only 1350mAh. The first step is to boost such a low voltage. The purpose of boosting is to drive the analog devices used in the next stage of voltage transformation. Many analog devices have operating voltages at 5V or 12V.

However, DC is not convenient to directly boost the voltage. Among power electronics, there is only one circuit that directly boosts the voltage of DC, called Boost. This method of increasing the voltage by changing the duty cycle has great limitations, and the boost amplitude is too small.

In the two boosting processes in the micro high-voltage pulse discharge device, neither Boost circuit can be used. The DC voltage must be converted to AC to complete the first boost. The boosted AC rectifier must be converted into DC to power the analog electronics.

The AC voltage of the first stage is boosted by the second high-transformer under the control of the analog device. The AC voltage of the first stage is boosted by the second high-transformer ratio transformer, and the two stages are boosted. The DC voltage of 1.5V will generate a high-voltage pulse of 30,000V.

It can instantly knock an adult man out of nowhere, which is the tremendous power generated by knowledge.

Liu Meng was also constantly thinking about how to use existing devices to transform. The Boost circuit was first rejected. The first step of boosting must adopt resonance technology and use a small-transformer to boost the voltage. This circuit is very simple, adding a capacitor. The transformer itself has a leakage inductance and can be recharged as an inductor to achieve resonance.

The purpose of resonance is to convert the DC voltage into an AC voltage so that the transformer can operate.

While concentrating on thinking, Huang Zong was watching the surveillance screen outside. The more he looked, the more he became unhappy. He remembered that Liu Meng almost destroyed his life last night, so he was scared and sweated. He thought that since his uncle Huang Sheng was not there anyway, he might as well take the opportunity to teach this kid a lesson.

Thinking of this, Huang Zong showed a wicked smile on his lips, and he couldn't help laughing out loud, without hesitation, and explained to Hu Zi, asking him to pay attention to the outside. He pushed open the bookshelf and entered the laboratory alone.

He punched Liu Meng in the head with a fist and cursed: "Grass, don't you get up yet, why are you thinking about the bad stuff while sitting stupidly? Are you still thinking about running away? You'd better die as soon as possible."

Liu Meng noticed the movement when Huang Zong opened the door, but he just ignored him and punched him and hurriedly dodged to the side.

The hero did not suffer any loss in front of him. Liu Meng was unwilling to pay attention to Huang Zong's provocation, and he had a cold expression and didn't even look at him.

Some people are like this. If you ignore them, they will feel that they have no sense of existence. Their existence is to disgust others to satisfy themselves. Huang Zong and Huang Sheng are indeed uncles and nephews, exactly the same.

Liu Meng is like this, and he still dares to look down on him. Huang Zong rushed up his blood and grabbed Liu Meng's neckline and shouted: "Damn, you dare to look down on me! Are you not a genius? Bah, I will teach you a lesson for this arrogant genius today."

The other hand hit Liu Meng's head. Liu Meng grabbed the arm he hit with one hand. His chest was extremely angry and said word by word: "As a waste like you, I just look down on you. No matter when, I look down on you."

Just when Huang Zong was secretly thinking about coming in, Liu Meng thought of a way, which angered Huang Zong and caused a conflict between the two.

Huang Zong was so embarrassed that his face turned red, and his other hand wanted to break free from Liu Meng's hand. He was a 1.8-meter-old man. Liu Meng was a little thinner than him. Although Liu Meng burst out with blue veins, his hand was very powerful and he held Huang Zong's arm tightly.

"You are so fucking, dare to challenge me." Huang Zong felt that his self-esteem was trampled on, and he could not subdue a thin boy. He was immediately angry and let go of Liu Meng's collar with his other hand and started fighting together.

This was the opportunity that Liu Meng was waiting for, and a full-scale conflict broke out with Huang Zong.

Liu Meng was also full of evil spirits and hated Huang Sheng and Huang Zong very much. However, his rationality made him suppress these emotions. He was originally an intentional dispute and no longer concealed it. He fought with Huang Zong.

A ruthless force filled my heart.

He flashed through Huang Zong's fist, and flexibly rang, hitting his ribs with a punch. Huang Zong felt pain and screamed.

Liu Meng would not give him a chance to breathe. He took advantage of the opportunity to hit him in the eye several times, and he was careful not to anger Huang Sheng and others, so he just swelled Huang Zong's eyes.

The situation was simply one-sided. Huang Zong was not convinced and struggled hard. As a result, Liu Meng was harder than the other, and another punch hit the nose. He suddenly had blood in his nose and his eyes were sore. He shouted: "Huzi, Huzi, where are you dying? Why don't you roll in quickly? This kid is going crazy."

Hu Zi didn't watch the surveillance screen at all. Seeing that there was a little wine left at noon, he took advantage of Huang Zong's absence and hurriedly drank it. After drinking, he saw that Huang Zongzheng was beaten up in the surveillance screen.

He came in with an iron stick, shouted and rushed over, smashing it at Liu Meng with a stick. Liu Meng could dodge, but the iron chain was locked under his feet. With a clatter, he couldn't dodge, but he was still hit in the back, causing a burst of pain.

Huang Zong was beaten up very hard. When he saw the strong aid coming, he also became angry and shouted: "Damn it, Hu Zi grabbed him for me and told him to know how powerful I am."

The big man named Hu Zi looked daisha, and he really had strength, thick skin and thick flesh, very resistant to hits, and his body was much more flexible than Huang Zong. He ignored Liu Meng's punch and rushed over and grabbed one of Liu Meng's arm.

Liu Meng was not at ease to be controlled by him. He rose up to resist and suddenly became a mess. However, the thin Liu Meng was still at a disadvantage when facing the two big men and was about to be caught by Hu Zi.

Huang Zong stared at Liu Meng fiercely, and was about to rush up to teach him a lesson. He slapped him at the head. Liu Meng was controlled by Hu Zi, but he was unwilling to surrender. He shrank down and avoided him.

Huang Zong was extremely angry. Neither of them could subdue a thin boy. He touched the iron stick under his feet, smiled sinisterly, and was about to hit Liu Meng.

"Stop!" Huang Sheng had just returned and entered the office. He saw the bookshelf being pushed aside. The sound of several people fighting came from inside. He had been standing and watching for a while, thinking that Huang Zong would teach Liu Meng a lesson. Although he was willing to cooperate, he would still slouch his spirit and come out to clean up the mess himself.

Unexpectedly, Huang Zong couldn't hit him, and he actually used an iron rod. After all, he beat Liu Meng out and developed a music player that was fart, so he had to rush in and scold him.

"What's going on? I've only been away for a few hours. It's so unreasonable." Huang Sheng said angrily.

"Uncle, this kid is not honest and refuses to work. He sits there in a daze. I come in and advises him to cooperate with us well. But the kid comes over and calls him to come over. Look, this kid is too cruel. My eyes are swollen and my nose is bleeding all over the floor."

Huang Zong was angry when he saw his uncle, and he was also a little worried. He was just unhappy when he looked at Liu Meng. First, Liu Meng almost destroyed his life last night, and second, he saw Liu Meng's strong skills. He also claimed to be a technical staff member, so he wanted to teach Liu Meng a lesson and find a sense of existence through a lesson.

Hehe, so what if you are awesome? I’m still beating you hard. With such thoughts, I naturally dare not let Huang Sheng know.

Huang Sheng stared at Liu Meng and smiled, but his eyes were a little scary, and he said, "Brother, seeing that you are so angry, I have to invite you here. Don't worry, as long as the development is completed, the price will be much more than you can. Do extraordinary measures in extraordinary times, don't resent me."

Liu Meng sneered and pretended that he had seriously injured his self-esteem by these two people. He was discouraged and said coldly: "I have said that I am not familiar with this kind of music player. I need to go back and reserve relevant technologies. I don't trust me. It's over, and I want to complete the development as soon as possible. Leaving here, my nephew is just here to disturb me. I'm sorry I really don't have the heart to develop it. I want to kill and scrape it. I'll do whatever you want."

As he said that, Liu Meng stood there with a tough attitude, looked up at the roof, and ignored Huang Sheng.

Huang Sheng still knew his nephew, and he didn't believe that Liu Meng would take the initiative to make trouble. He still had a smile on his face. He looked at Huang Zong and slapped him, then slapped him again, stunned Huang Zong.
