Next to Tang Jiayi sitting in the flower bed under a ginkgo tree, Atletico looked up at the red clouds in the sky, "The morning glow doesn't go out, the sunset travels thousands of miles, God really gives face these days!"

"Oh, why didn't I find out before, why did you always want to come out one at a time? Selling mobile phones and selling dozens of them was too troublesome to do, and finally threw them all at me; they went to learn to drive, and they came back after a few classes; and now you are doing this aerial photography, didn't you say that you are not going to make a 3D map outside the campus?"

Regarding the coquettish complaints of the girls around him, Atletico Madrid chuckled: "It's not that the plan can't catch up with the changes, the mobile phone didn't do a good job of market research and joined in a hurry, and as a result, it was depressed by the supply chain and logistics card." The kind of thing that the little girl likes on the big sticker, you really can only let you do it, don't you know how much your performance has dropped if you haven't been looking at the store below in the past two days? ”

"And what about this?" asked the girl, looking up at the sky, searching around, and pointing to the "Boeing 747" in the sky.

"It's not that you can't stay at home, there are a lot of messy things, and the old house at home is going to be demolished, so it's better to avoid it. Atletico put his left hand around Tang Jiayi's slender waist, "You see it's not very good now, I have not only swam in the mountains and played in the water, but also done the work." ”

"If you want to go out with me, it's fun, why do you still have this thing with you?" Tang Jiayi patted the tablet on Atletico's lap. It's boxy, with a length, width and thickness similar to the keyboard part of a laptop, but instead of a keyboard, it's a touchscreen. There is also a protective cover attached to it under the screen, and two styluses are also inserted into the protective cover behind the screen.

"This is my latest masterpiece, the core components of the six phones are combined, the weight is more than half that of the original notebook, and the performance is basically enough. ”

"No matter how many mobile phones are combined, in the end it is not a mobile phone, and it is too power-consuming for you to get so many mobile phone chips into it, and it can only be used for less than a day when fully charged. The girl pouted and looked at the computer screen, which showed a simple 3D topographic map with a striking blue plane moving, which was the position of the remote-controlled plane in the sky.

"In fact, the chip doesn't use much electricity, and the six mobile phone cPu with a main frequency of 100 trillion are not turned on at the same time, and the system will automatically turn on and off according to the load, and the real power consumption is the bulk of this screen!"

Pointing to the tablet on Tang Jiayi's lap, Atletico said helplessly: "Originally, I planned to use the more power-efficient black and white electrophoresis screen, which does not need a backlight, and relies on reflecting external light to display graphics, which is very power-saving and can not be charged for a week, but finally gave up." ”

"So what screen sounds so powerful, why don't you use it, can't you buy it?

"No, this electrophoretic display technology has been invented and mass-produced a long time ago. However, the advantages and disadvantages of this technology are very obvious, its advantage is that it saves power, and it is more eye-friendly when displaying content without refreshing flashing, and the disadvantage is that there are only two colors, but the display response time is super long, and it is only suitable for static display of text or pictures. In the past, the mobile phone screen was only used to display text messages and make a living, but it was not suitable for a computer screen at all. Even if you can barely use it, when the screen is constantly refreshed due to the constant change of software data, the power consumption of the electrophoresis screen will surge, and the standby advantage will not be so great. The shallow Jupiter communication who was in contact with me on the buckle recently promised to bring me a few ink screens to try the effect when the time came. ”

"The main thing is that the current battery capacity is too small, in the past, when the mobile phone was a black and white screen, it was a lithium battery, and now it has become a color screen or a lithium battery. As a result, the power consumption of the mobile phone has increased several times, and the battery capacity has not changed at all. ”

"It is a polymer lithium-ion battery, the real lithium battery anode is a metal lithium element, lithium is a spontaneous combustion in the active metal air, if it leaks a little air into it because of thermal expansion and contraction, it becomes a large torch, and it is too dangerous for civil use. Now these rechargeable lithium batteries use metal lithium compounds as electrolytes, which will not produce lithium elements when charging, although there is a small chance of bursting if used improperly, but it is much safer than lithium batteries. Ordinary lithium-ion batteries are mostly cylindrical, like ordinary batteries, and the thin plate batteries on mobile phones are polymer batteries, and their electrolytes are gelatinous solids, which can be made into various shapes. ”

"For example, if you think that the battery of a laptop is six or eight cores, it means that the battery is six or eight cylindrical lithium-ion batteries connected together. Lithium-ion batteries have a nominal voltage of 3.7 volts and a full charge of 4.2 volts, while laptop batteries generally have four lithium-ion batteries connected in series to 14 volts and then connected in parallel with each other. I use a whole polymer battery on this tablet, the capacity remains the same, but the volume is reduced a lot because of the lack of a shell. ”

"Okay, okay, I know you're the top student in science this year, a strongman with a score of 298 in science, so you don't need to give me science battery knowledge. ”

"Oh, I'm just a little emotional, don't be so sarcastic, right?" Atletico hurriedly begged for mercy, "Okay, the plane has finished sweeping this piece, I'll go recover it." ”

Atletico put the tablet aside, stood up and walked forward a dozen steps, only to see the "Boeing 747" four-engine wide-body airliner in the sky slowly flying towards him, slower and slower. Atletico jumped slightly, grabbed the fuselage of the plane with both hands, and landed on the ground.

Because of the use of hydrogen balloons to fill the interior space, the remote-controlled aircraft was quite lightweight, and Atletico easily grabbed the wing with one hand and the tail with the other and placed it on top of the flower bed where he was just sitting. Tang Jiayi handed over a usB data cable, and Atletico connected it to the interface at the back of the plane that was blocked by the movable soft cover, and the tablet computer quickly recognized it successfully, and then Tang Jiayi began to operate the copy file.

"Actually, you don't have to be so troublesome at all, you should be able to use Bluetooth or wIFI for video transmission, right?"

Atletico sat on the side after connecting the line, and nodded when he heard the words, "Yes, and it will feel like you are in the sky with eyes, it will be cool." But for the time being, in order to enhance the endurance, I didn't get that function, and this plane scans the map according to the preset program most of the time in the sky. ”

Patting the plastic fuselage, Atletico said with a wry smile: "Don't look at it, it is copied in strict accordance with the shape of the Boeing 747, and the aerodynamic shape of the Boeing aircraft has also been inherited, in fact, its shape and structure are not suitable for the low-speed flight of model aircraft." Not to mention this engine hanger, the size is too small to fit in, and the larger fan blades seriously affect the thrust. At the beginning, there was no way, and it was the most suitable to choose and choose, so I had to make do with it first. If I hadn't had the idea to stuff a lot of hydrogen balloons into it to increase buoyancy, this thing might not have been able to fly at all. ”

"Then why don't you make a hydrogen airship, isn't it better, more buoyancy can bring more batteries and equipment, and wireless video transmission is not a problem. ”

According to Archimedes' principle, the buoyancy of an object in a liquid is equal to the weight of the liquid it expells, and the buoyancy gained by a hydrogen balloon in air is equal to the weight of air. Physics rolls on all day long, usually the density of air is 1.29 kilograms per cubic meter. In other words, a hydrogen balloon with a diameter of more than one meter is needed to provide one kilogram of buoyancy, which is not easy to carry, and landing is also a problem. ”

After Tang Jiayi signaled that the data transmission was completed, Atletico opened the backpack, took out a new battery from it and replaced it with the model airplane, and then reinstalled it. Then it was released again, this thing is not big, the length and width are only about 70 centimeters, and the weight is not much, but it is quite troublesome to hold it with bare hands, so Atletico usually prefer to carry a few spare batteries in a backpack than to "carry a plane".

"I'd be planning to get a more formal, slightly larger remote-controlled airship, but it looks like it's going to have to be approved. Atletico said: "So in the end I got back on the plane." ”

"I think you're actually just like Wei Wei and the others, you take advantage of the summer vacation to make up for your childhood. Tang Jiayi folded the sun umbrella in her hand into the side pocket of her backpack and stood up, "Okay, it's time to shift positions again, but you don't have to be in a daze at the Taoist temple." ”

The place where the two of them are located is a parking lot in a scenic area, and they have been here several times.

In the words of Atletico Madrid, "This Taoist temple has a long history, and has been built and expanded many times in its history for hundreds of years, so although its buildings are all traditional Taoist architectural styles, they are all incompatible in details, including the characteristics and styles of ancient buildings in many historical periods, which is of great reference value." ”

After the results of the college entrance examination came out, after participating in several thank-you banquets and dinners, Atletico Madrid pulled Tang Jiayi away.

The two of them began to take a short trip within a one-day drive around Pingxian County, and the reason for telling Tang's parents was to take advantage of the holiday to take a good look at the scenery of their hometown, and by the way, collect some real souvenirs, which they could take to the school to give away.

The reason why he only wanders around the neighborhood is due to a variety of reasons: on the one hand, there are still many scenic spots to see around Pingxian County, which is not considered a poor mountain and bad water, on the other hand, it is also because Atletico Madrid's plane is not easy to transport, and another reason is that Atletico Madrid has used the second "goddess mask", and he needs to stay at home at any time to prevent accidents.

Walking on the way to the bus station, Tang Jiayi asked about the goddess mask.

The first user of the "Goddess Mask" was Tang Jiayi, and after insisting on wearing the mask to sleep for a month, Atletico finally collected enough data to officially open up the "Goddess Mask" to her other functions besides promoting sleep and weight loss, and she immediately felt the difference.

The most powerful thing about the "goddess mask" is that it can "copy" the user's own brainwave signals, "cut and combine" them as needed, and then "feed" back to the user themselves. From stimulating facial muscles, creating dimples, smoothing wrinkles, to growing eyelashes and eyebrows, reducing pores and hair, and even regulating body rhythms and prolonging the menstrual cycle, it is possible for the eldest aunt to come only once a year.

Of course, because it is the first experimental product, Atletico Madrid did not directly unlock all its functions after it was officially launched, and now it only unlocks skin beauty-related functions, regulating endocrine or something, but vaguely mentioned it to Tang Jiayi. The girl naturally didn't believe it at the time, which was too sci-fi. But facts speak louder than words, and seeing that her skin has really been improving in the past few days, she became curious again. For mobile phone users, please visit http://m.piaotian.net
