Otaku Engineer in Great Tang Dynasty Chapter 273: Start your old business!

"Master, Xiao Xi brought all your changes of clothes!"

Li Zexuan returned to Zuifengxuan. About a quarter of an hour later, he didn't wait for Bo Fu to deliver materials, but waited for Xiao Xi to deliver clothes.

"Well, hard work, Xiao Xi, you can go back after putting these clothes in the back room!"

Li Zexuan said on several cases while recalling the relevant knowledge of physical chemistry in the past life.

"Master, Madam is worried that you will suffer here alone, so she told Xiao Xi to stay here to take care of you these few days! Xiao Xi will go back and bring you three meals a day!"

Xiao Xi turned around and said, holding the baggage she brought over.

"Huh~? My mother really said that?"

Li Zexuan raised his head and asked.

"Of course...Yes, Xiao Xi went to clean up the room for Master!"

Xiao Xi's face blushed and responded, then hurriedly turned around, holding the package and went inside.

In fact, after Sambo sent back the news that Li Zexuan would be staying in the workshop for a few days, Mrs. Li didn’t expect to send a maid to take care of her son’s diet and daily life. After that, Mrs. Li sent her over.

When I thought about it, Mrs. Li's meaningful eyes and smile made Xiao Xi's ears red with shame.

......................

"My boss, this is the material that Fu Guan asked the little one to send over!"

Not long after Xiao Xi entered the back room, Song Xiaosi brought a package. After experiencing the lesson last time, Song Xiaosi's smile now has a trace of caution, and he no longer laughs and laughs like Meng Lang as before.

"Hmm."

Li Zexuan took the package, opened it and checked it carefully, and then nodded with satisfaction: "Very good! One is not bad, you can go back for the fourth year, it's almost time for work!"

"Master, the younger one is not in a hurry. You can also live in the workshop at night, or you can stay here if you are younger. If you have any instructions then, the younger one can run errands for you?"

Song Xiaosi smiled diligently.

"No, there is nothing wrong with me, I can do it alone, you should go back, Xiaosi!"

Li Zexuan smiled and replied.

At this moment, Xiao Xi cleaned up the room and came out and said, "Master, your room is cleaned up!"

"Well, it's hard work!"

Li Zexuan nodded.

"Ah~! Master, then, that little one quit!"

When Song Xiaosi saw Xiao Xi, he immediately reacted, and at the same time he hated himself for talking. The young master of his own family is a red-sleeved sweeter, so I don't need to come and help myself.

"Hey!"

As soon as Li Zexuan saw Song Xiaosi running away, he knew that this kid had thought a lot and planned to call him back, but after thinking about it, I thought it was fine. There is no explanation for this kind of thing.

"Xi, there is a wing room on the east side. Go and clean it up by yourself. Master, I'm going to start working!"

Li Zexuan mentioned the large bag of experimental materials, walked to the room, and smiled at Xiao Xi.

"Oh!"

Xiao Xi saw that Li Zexuan does not need her help now, so he said "Oh", and Yiyan went to another room to clean up the room. After all, she will live here at night, so she can't sleep with Li Zexuan in the same room. ? Although she has thought about it, but......

.......................

"Hey, after having traveled for so long, I finally started my career!"

Li Zexuan put the package of materials on the "experimental bench" he temporarily put together with four long tables. Looking at this simple "laboratory", he felt a little emotional for a while.

As an engineering student and an engineering student of his profession, I didn’t know how many circuit boards had been soldered in the laboratory before. I didn’t expect to travel to the Tang Dynasty and still have to do his job. The difference is that his current The experimental conditions are more shabby. Of course, the experiments done are more basic and simple, incomparable to modern integrated circuits.

"The work has started. Today, the young master let the battery come to this world more than a thousand years in advance, haha! Dear Mr. Volt, I'm sorry for stealing your Ming!"

Li Zexuan eagerly muttered to himself.

Yes, what Li Zexuan has to do is the simplest voltaic battery. what? Do you think the voltaic battery is weak, why not build a motor?

Damn, big breasted brother, you don’t have a backache when you stand and talk, and you want to run without learning how to walk. You think the motor is so easy to build! You traveled to the Tang Dynasty, come and make me a try? Can you make it in a month or two? Li Zexuan now wants to produce electricity immediately, and then realize his next plan. How can one or two months be spent on making a motor?

Li Zexuan had watched the TV series "Mythology" in his previous life. In it, the Yi Xiaochuan played by Hu Ge traveled to the Qin Dynasty. Because the mobile phone ran out of power, he made a hand-cranked motor... Of course this is the screenwriter’s nonsense. In fact, his thing cannot be powered at all.

Well, magnets existed in ancient times. The wire used was the gold thread on the clothes of the future Mrs. Liu Bang, Lv Hou, but his gold threads did not have an insulating skin, and there was no difference between a coil and a gold lump. The screenwriter doesn’t know that the real motor coil is enameled wire, let alone charging the mobile phone, but also rectifying and stabilizing... In addition to charging the mobile phone, don’t you need an interface cable...

Li Zexuan, who was born in science and engineering, has been entangled in this matter for a long time. He also thought at the time that if he really traveled to ancient times, when he needed to recharge his mobile phone, he should "adjust to the time" (the ancient materials were limited), and what kind of device would be good? Is it a simple hand-cranked motor, or some other weird stuff?

What? You said that there was no signal in ancient times, why do you charge your phone? You can use your mobile phone as a video camera. Is your mobile phone only for making calls? If there are some * expansions in the phone, and use the past to contribute to the emperor, maybe you will have all the glory and wealth of your life...

After hard thinking and putting dogs and pigeons to find needles on the Internet, he really found it...

In 18oo, the famous scientist Volta (in fact, it is Volt, and the unit of voltage is Volt. I don’t know why those idiot translators in China call him Volta for a while, Volta for a while, so that when Li Zexuan was in middle school, he was young The mind is often confused), understand that the world’s first battery is also the ancestor of modern batteries.

He found through experiments that a piece of paper soaked in salt water between two different metals will generate electricity. He soaked in salt water with blotting paper, stacked a layer of silver flakes, a layer of blotting paper, and a layer of zinc flakes, and then connected the top metal sheet with the bottom metal sheet with a wire~IndoMTL.com ~ Now you can measure voltage and current. This device is now called a "voltaic stack".

The principle of a voltaic battery is that after two different metals are in contact with an electrolyte solution, the ions in the solution form a directional movement to generate current.

Until now, the dry batteries we use are modified voltaic batteries. In dry batteries, ammonium chloride paste is used instead of salt water, graphite rods are used instead of copper plates as the positive electrode of the battery, and the outer shell still uses zinc skin as the negative electrode of the battery.

Is it easier to make a battery compared to making a motor?
