Tang Jiayi glanced at Atletico Madrid's electronic watch, and said suspiciously: "You have changed to a new electronic watch, which looks at least half thinner than the original." ”

"I changed the design and reduced the weight by half, but it was still the same shell, but I removed the bottom half of the shell, so it became thinner. ”

If you take off the electronic watch in Atletico Madrid's hand, you will find that the back is a piece of soft rubber, if you tear off the soft glue and find that it is a circuit board, all the components on the pin solder joints have been carefully polished and trimmed, some of the solder joints are ground very low will be completely covered by the soft rubber, some are relatively high, and these spherical solder joints through the soft rubber can be in good contact with the skin when wearing the watch.

Originally, Atletico planned to redo the circuit, so that the components are directly connected to their skin through the pins, so that some peripheral circuits can be omitted, and the maximum size of the device can be reduced, but in this way, the electronic watch cannot be taken off, and as soon as it leaves Atletico's wrist, it will be "broken" without any display. So after all the considerations, it was changed to a patchwork version like this.

"Isn't this waterproof, and won't it be broken if it gets sweaty or something?"

"I plugged all the gaps with waterproof glue, and this performance didn't even have a button, it was completely seamless. ”

"So how do you change the battery and adjust the time? By the way, you can't get a touch screen interface for it, right?"

patted his trouser pocket, Atletico said: "Use your mobile phone Bluetooth, you now use your mobile phone to search for Bluetooth devices, the one named 'SS-01' is it, of course you don't have a password that can't be connected." As for charging, I experimented with wireless charging on it. Electromagnetic induction, electricity generates magnetism, magnetism generates electricity, as long as it is placed near the wireless charger, it can be charged. ”

In fact, this guy is talking nonsense when he opens his eyes, Atletico Madrid removed the original rechargeable lithium battery at the bottom of the electronic watch, and installed a small button dry battery on the circuit board, which will only be used for power supply when the electronic watch leaves the skin, and it can even be completely turned off when sleeping at night, so you don't need to change the battery for a long time, and naturally you don't need to charge it.

However, Atletico naturally couldn't tell Tang Jiayi that his skin can generate electricity and drive electronic devices, so he had to use a "white lie" to fool the past.

"I know that although I don't learn physics as well as you, I'm still not confused about electromagnetism. Tang Jiayi shook her fat hand and said, "Oh yes, can you also transform the mobile phone into wireless charging?"

Nodding and shaking his head, Atletico said, "Theoretically, it's possible. However, wireless charging now has a distance limit, and the increased convenience is not so obvious, so it is better to change to a spare battery that has been prepared a long time ago. ”

"And there will be energy loss in the conversion process, it doesn't matter if you watch or mobile phones, and it is estimated that someone cares about the extra wasted power in the notebook or something. Tang Jiayi added.

"In fact, if the wireless charging distance can be farther away and the energy loss is lower, it should be promising. Since the invention of lithium batteries, the battery capacity has basically never increased, but the cPu frequency of mobile phones is getting faster and faster, the screen is getting bigger and bigger, and the demand for battery capacity is still increasing. Other components use better, thinner and lighter materials, and the weight savings are all taken up by larger and larger batteries. When the battery is changed every two or three hours, people will remember the benefits of wireless charging. There should be a lot of scientists studying this now, but I don't know if we can use such a battery-free mobile phone when we graduate from college. ”

"By the way, Atletico Madrid," Tang Jiayi pointed to herself and asked, "Just now the old class asked you to introduce your experience, why didn't you mention your missing software?"

Atletico bumped the girl next to her on the arm with his elbow and said, "If I had just said it, it would have been an advertisement." I'll wait for someone to come to the door by myself, and someone should come looking for you soon. ”

"What are you looking for me, what are you looking for me?" Tang Jiayi wondered.

"I'm looking for you to inquire about the truth or falsehood!" Ma Jing pointed to the stack of practice papers stacked on Tang Jiayi's table, and said: "They haven't seen how I practiced in retreat, but how you have been reviewing recently, they can all see it! ”

"What are you talking about?" Tang Jiayi pushed Atletico with a smile and said: "But seriously, I didn't expect that I didn't find new questions to do by myself during this time, so I used your software to learn solutions at home, and then turned back in the classroom to redo the previous mistakes, I didn't expect that the improvement in grades would be so great!"

"It's not all!" Atletico patted the book in front of him and said: "Say a thousand things and ten thousand, the high school knowledge examined by the college entrance examination, these people in our class are all people with a solid foundation, and they can all get high scores." But why do you lose more than 100 total points, it is because the teacher who wrote the question deformed and deformed the question, and then dug a pit and buried a trap. Maybe you were cheated by this question, and she was cheated by that question, so there are always people who get hit, and there are always very few people who can get a full score. And the software I gave you can analyze your problem-solving ideas and thinking blind spots by analyzing all the problems you did in your three years of high school. Wait until you make up for your thinking blind spots through intensive training, do what you do wrong, don't do, those types of questions that can make you lose points will be fewer and fewer, and your grades will be higher and higher. ”

Tang Jiayi is not surprised by Atletico Madrid's bold statement of getting a full score, after all, Atletico Madrid's three subjects of mathematics, English and science are already very high this time, if you strengthen it again, you don't need to answer the questions beyond the outline content, maybe you can really get a full score.

"And if someone asks me about this, what should I say?"

"Let them prepare the papers they have done, and then give them to me, and I will help them mail them to the research institute over there, and then upload them to me from the Internet when the special training question bank is compiled there. As you can see, my special training question bank is different from yours, and everyone's special training question bank needs to be based on data analysis to get it. Therefore, I must be given the papers they have done, and they must have done it myself, and the questions that I have copied the answers must be treated according to the questions that I will not do, and the answers must be left blank. ”

"Jiajia, how much do you think I should charge for the appropriate handling fee? This is not cheap to mail a thick stack of rolls. ”

Looking at Atletico Madrid's expression of a wealth fan who fell into the eyes of money, Tang Jiayi threw him two rolls of the eyes, turned her head away from him, and suddenly turned her head again and looked at Atletico with a smile: "Then, horse profiteer, how much do you think I should pay you for the fee?"

"You don't need it, who are we with, haha!" Atletico snorted, "It's a big deal that you will cook me for the rest of my life to pay it back." ”

"No! I remember you didn't bring a thick stack of rolls with you when you went to the provincial capital. And my rolls are either here or at home, not yours. Tang Jiayi blinked her bright eyes and looked at Atletico Madrid curiously.

"Shhhhhhhh I can't forget it now!"
