Zhao Xilin saw Lin Chen throw a round blue ball packed in a transparent plastic bag on the table, the thing looked very light, it fell on the table and bounced up gently, fell and rebounded again, and it didn't calm down several times.

"Is this today's first prize? the mutation bubble?" he asked.

"Hmm. Lin Chen said noncommittally, sat down in his seat after speaking, reached out and grabbed the blue ball that was still bouncing slightly on the table, and said: "I'll just say, in the past, the mutant summoning beasts were only at the second prize level, but today there is a mutation bubble in the first prize, it turns out to be the physical version." ”

Bubble is a famous summoning beast in Netpig's "Journey to the West Q", which was originally the logo and mascot of Netpig's instant chat software Bubble, but because the instant chat software field buckles the penguins dominate the rivers and lakes, the presence of bubble software that is too close to it has declined, and few people know about it.

At least for millions of fantasy players, Bubbles is a collection of rare and adorable summons, not chatbots.

In fantasy games, there is a certain chance of encountering ordinary yellow bubbles or even mutated blue bubbles when encountering monsters. And the pink Super Bubble, which has a more cute pink bow and small fist, is a mythical beast that many people in the game dream of. However, because of the relationships that can only be obtained by completing complex regular activities, these cute beasts are not common in the game, but are the most common, and the spherical yellow bubbles with a pair of eyebrows and large eyes are more common. Even the relatively rare mutant blue bubbles are quite numerous.

And the space station Internet café has hoarded a lot of blue bubble summoning beasts as the second prize of the daily hourly lottery. Anyway, for Atletico Madrid, it is very easy to open more clients to brush these special summoned beasts, and the green hang-free claim of the fantasy official cannot affect him at all.

With the number of Mi Chat users reaching one million, the space station Internet café no longer provides the Honey Chat number as a second-prize reward, but instead provides the Honey Chat Pretty Number with a shorter digit. The unique software architecture of Honeytalk allows users to bind and replace it with their own Bee Pass at any time after obtaining a new Honeytalk account. The reason why there is no custom modification of the setting of the honey chat number is completely for the potential of the deduction, just like the Yaya number of Yaya's voice is also used to use a digital ID that cannot be easily replaced.

This is the huge influence of industry leaders, and latecomers will have to follow in the footsteps of others, intentionally or unintentionally.

Lin Chen's left hand gently kneaded the blue bubble in the palm of his hand, it was a blue rubber ball about a dozen centimeters in diameter, two fairly delicate erect oval eyes, and curved eyebrows, which looked like he was laughing.

Zhao Xilin reached out and took the bubble from his hand, pinched it, and felt very soft and elastic, "No wonder I jumped on the table for so long just now, it turned out to be a big pinball!"

Pinball is usually a colored rubber ball with a diameter of a few centimeters, which will bounce up quickly when it falls to the ground, or after falling to the ground hard, it can bounce continuously and land for a long time on hard and smooth ground.

"It's not a pinball," Lin Chen gently placed the bubble on top of the newly added wireless charging pad on the table.

"It has batteries, chips, motors, and sensors in it, which can be started remotely and then it will jump up and down. But now we have to recharge his batteries first. ”

After he pressed the switch on the charging pad, it didn't take a few seconds for Kung Fu's left eye to light up with a faint green light.

"One eye is bright, the other eye is blind, look for them to change!" Zhao Xilin said.

"I'm going to go to you!" Lin Chen shook his head and said, "Its eyes can change into several colors, and the green light in its left eye means that it is charging." When it is fully charged, both eyes will light up together. Oh the instructions are here, you don't say I forgot them. ”

As he spoke, he pulled out a folded piece of coated paper from his pocket, on which a large number of pictures and words were printed.

As a result, the manual was unfolded and looked at it, and Zhao Xilin raised his head: "I didn't expect this little thing to have a high technical content!"

"That's, otherwise how can it be worth hundreds to be put into the first prize?" Lin Chen said: "But it's not complicated, after all, the weight is there, the heavier the exercise, the greater the energy required, and the corresponding battery capacity will be larger, and finally it will become a big lump of batteries with a few circuits." In fact, a lot of its cost is because of the helium filled inside. ”

There is a brief schematic diagram of the principle on the manual, and this little thing is roughly a double-layer structure, with a rubber balloon filled with helium on the outside and a plastic ball in the middle. Inside, the plastic ball contains chips and polymer lithium-ion batteries, as well as a counterweight rod that can be turned horizontally and is attached to a small motor.

The plastic ball stretches out a spring telescopic rod in six directions, and the other end is fixed on the inner wall of the rubber balloon outside. The structure of the spring telescopic rod located below is different from the other five, and it seems that it can be elongated by electricity, resulting in a jumping action.

Helium is the second lightest gas on Earth, second only to hydrogen, a rare gas less than one-seventh as dense as air, but it is non-toxic, harmless, non-flammable and much safer than the cheaper hydrogen.

"Cut, it's another profiteer's gimmick!" Zhao Xilin pursed his lips disdainfully, "The weight of a liter of air is only a little more than one gram, according to Archimedes' principle, the buoyancy generated by a balloon of the same size is equivalent to the weight of the air it distributes, so a balloon with a volume of one liter only has a buoyancy of more than one gram." The ball is up to 16 centimeters in diameter, and with a radius of eight centimeters, the volume is just over two liters. In other words, even if you ignore the volume of the plastic ball inside, it only has a little more than two grams of buoyancy at most, and the effect is basically equal to nothing. ”

"Maybe they're just filling it with nitrogen, or it's just air, and the average person can't get it out at all. ”

"You're good at physics, you're not an ordinary person, you're a second-class person, it's all right!" Lin Chen joked with a smile.

"Actually, I'm more interested in the motor in it, but ......" Zhao Xilin looked at the blue rubber balloon on the table not far away with some regret.

Lin Chen understood what he meant, there was no structure such as an open-hole screw on the outer surface of this bubble toy, it was fully enclosed. If you want to disassemble and check the structure inside, you must cut the rubber balloon on the outside and let go of the "helium" inside.

Thinking of this, he said: "Maybe they specifically emphasize that it is filled with helium, not nitrogen or even air, in order to increase the cost, right? ”

"Maybe. Unable to dismantle and see the real thing, Zhao Xilin had no choice but to bow his head and continue to look at the manual.

The principle of this thing is very simple, the inflatable rubber ball itself has a good elasticity, and they used six spring telescopic rods to fix a plastic ball inside, and the movable spring at the bottom should be a linear motor, which can compress the bottom spring after being energized, and the spring rebounds to squeeze the ground after the power is off, and the entire rubber balloon is bounced into the air by the ground reaction force. The movable counterweight bar on the equatorial surface can rotate horizontally 360 degrees, and slightly change the center of gravity of the ball, so that the direction of the spring rebound is not perpendicular to the ground, and the direction of the ground reaction force will naturally not be perpendicular to the ground, which makes the ball can be bounced in any direction horizontally.

The external performance is that this small ball can jump freely at will, jump as high as you want, jump as far as you want, jump as far as you want, and jump directly in any direction of 360 degrees horizontally. Of course, because of the power limitation of the linear motor, it cannot jump too high or too far.

But this alone is already very powerful, after all, it only uses two structural motors to achieve free movement in the horizontal direction. Moreover, if there is a more accurate sensor, it can realize free movement in the three-dimensional hemisphere space, although the jumping movement efficiency is not high.

"This thing should be the work of that genius Ma Disheng again," Zhao Xilin muttered, "It's really hurtful to be a classmate with a genius!"

"The husband is the only one who can't fight, so the world can't fight with him. He is strong, he is strong, the breeze caresses the hills, he is horizontal by him, and the bright moon shines on the river. Lin Chen heard the low sigh of his old friend and memorized two famous sentences to comfort him.

"He is cruel to himself, he is evil, and I am full of anger. If only there really been "Jiuyang Divine Skill". Zhao Xilin was very clear about the origin of the two sentences that Lin Chen recited, and he also memorized the following sentence.

But there is no more, after all, there is no mention in the novel.

Although there is a lot of indirect contact with this genius Atletico classmates, Zhao Xilin and Lin Chen have not really seen Atletico Madrid, after all, although they are in the same school, they are not in the same college, but the most important thing is that the grade difference is two levels, and when Atletico moves to the seaside campus where they are now next year, the two of them have also graduated.

"There is only more than one semester left, and the forbearance is over. Lin Chen said with a smile: "On the contrary, the younger students of the following grades will be pressed below by him for several years." ”

"That's right, those sports students should probably cry. That guy is a monster, not only has a well-developed brain, is good at making money, can give himself scholarships, but also has a well-developed cerebellum. In addition to the women's events, which were really unable to participate in this school sports meeting, people didn't just pick a few to participate in other events, and they easily won the championship. With his physique, strength, speed, and reflexes, he was completely unwilling to sign up for too many events without blowing up the medal list. ”

"I wonder if the Biological Science Institute brought him to the laboratory bench to analyze the slices?"

"It's definitely not sliced, the school still expects him to go to the Universiade alive, how can he be scrapped?" Zhao Xilin's voice changed, "But it is estimated that pulling out his hair, drawing blood, urine CT, electroencephalogram or something should be indispensable." ”

As he spoke, Zhao Xilin glanced up and found that he didn't know when the two eyes of the bubble had lit up, and the two eyes were green.

So he raised his finger and said, "The electricity is full." ”

"Hmm. Lin Chen reached out and grabbed the blue bubble, pressed it down with his palm, and pressed it on the table, until the two eyes that had been extinguished just now because of leaving the charging disk lit up again.

As soon as he let go, the blue bubble bounced and jumped, bouncing slowly on the table, up and down.

Lin Chen found a blue bubble icon in the Internet café version of the Bee Wisdom Center on the computer, double-clicked it to open it, and clicked a few buttons on the software called "Bubble Controller" to complete the pairing verification. Then as he pressed the left arrow key of the keyboard continuously, he saw that the bubbles that were slowly jumping on the table were no longer jumping straight up and down, but jumping along the table and jumping in front of Zhao Xilin next to him.

"It's fun to play with a Bluetooth phone, and it feels weird to control it remotely on a computer," Lin Chen said.

The control of the bubble is very simple, press the up, down, left, and right arrow keys in the keyboard arrow key area to make it jump forward, backward, left, and right, and press the space bar to jump on the spot. When you hold down the spacebar, it will actively shrink the lower spring, and when you release the spacebar, the spring will be released synchronously.

"If you can make it bigger, make it as big as the one in the game, walk on the road, follow such a real bubble behind you, you should have a 100% return rate, right?

"Is it okay to be a little promising?" Lin Chen scolded with a hateful smile, and then said: "I also specifically asked the store manager who gave me the award, and he said that it was the bee who was talking to the net pig about the image authorization of bubbles. If the price is not high, the net pig will buy the license, and then make a larger model, or even a plush version. If the net pig and lion opened their mouths, they would give up and cut out their eyes and turn them into vibratory eggs. ”

"Jumping eggs?" Although he is a single person, Zhao Xilin, who has a lot of experience in watching action romance movies in island countries, still knows what the jumping egg is when it falls to the ground, so he can't help but ask rhetorically.

"Shhhhh ”

Zhao Xilin's face was also slightly red, sitting upright and staring at the screen without squinting, and he was also injustice to his old friend, "Your sister! ”

After finding that there were few people around looking at him through the monitoring system, Lin Chen turned his head to Zhao Xilin and said in a low voice: "You shouted wool?"

"It's not all your fault, don't tell me you don't know what a vibrator is?"

Lin Chen smiled obscenely: "I don't know what it is, except for massage sticks, Japanese women's favorite things." ”

"But literally, if you don't have the two eyes outside, this thing will indeed become a jumping egg, and it seems to be a legitimate thing to call it a jumping egg. Zhao Xilin said in a low voice.

Lin Chen held down the spacebar with his right hand to stop the bubble, and grabbed it with his left hand. After releasing the space bar in his right hand, the bubble jumped up and down a few times but did not come out of his hand, and then the green light of its two eyes flashed three times and then did not move.

"In fact, if this thing is made small, it should be much better than the current vibrator that uses an ordinary DC brush motor. The bubbles bounce at a lower frequency, closer to the finger slashing frequency, and are truly 360 free-beating. Now that kind of vibrator is actually a vibrating egg, inside is a DC motor connected to an eccentric wheel, as if the mobile phone vibrator is also about the same principle. ”

"Well, first of all, you have to have a girlfriend. Otherwise, where do you use the vibrator? Stuff the chrysanthemum? Be careful that the chrysanthemum is full of wounds. ”

"Dong Chou was really unlucky, and let the national teacher go to the chrysanthemum stage to play and sing, but you have been talking about it for a whole year, why haven't you talked enough?"

"Okay, okay, stop, stop talking, let's not talk about this, we don't need these things now. Unless Lin Chen, you really intend to develop in this direction......"

"Don't tell me, I really have that in mind. Lin Chen said with a smile.

Zhao Xilin reached out and touched his forehead, "I don't have a fever!"

Lin Chen's head was full of black lines, "I'm serious!"

Zhao Xilin was also a little caught off guard by this turning point, and he couldn't say anything, and finally just spit out: "What are you going to do?

Lin Chen shook his head, "This thing looks simple in structure, but the technical difficulty is actually very high, I don't plan to do this for the time being." My original plan was to make smart airplane barrels. ”

"Understood," Zhao Xilin nodded clearly, "It is a correct choice to solve the man's problem first, and then solve the woman's problem." ”

"It's not as complicated as you think!" Lin Chen was already helpless, grabbed the mouse on the table and shook it, and said: "When I used to play games, I thought about making an airplane barrel with a game controller function in the future, so that I don't have to click the mouse with my right hand and grab the joystick with my left hand. ”

"Khan!" Zhao Xilin wiped his sweat on his forehead, "Classmate, your thinking is really broad!"

"Go! You're a mentally ill person with a wide range of ideas, and mentally handicapped children have a lot of fun! You dare to say that you haven't played the hgame of the I club, and you haven't been excited when you played these games and then stroked off easily?"

Because the relationship between solo music is not as good as public music, it is not clear to the girls, but these games and videos have always had a high sharing rate among boys. Some dormitories have even organized group observation and learning, although Zhao Xilin did not participate in the group observation and tasting activities because of embarrassment, but he did play a lot of hgame when he was alone in the dormitory. Especially the 3D game character modeling created by the island country I Club next door to the east is childlike **** and easy to push down, which is very in line with his aesthetic taste. He has collected and played all the 3DHgames of the I Society, and I believe that the situation should be similar to that of Lin Chen.

In fact, if you think about it carefully, it seems that you have indeed had the kind of situation that Lin Chen said, if there is really such a smart aircraft barrel that can replace the keyboard and mouse, it should be a good thing for the benefit of the masses.

"Okay!" Zhao Xilin nodded slightly, "Do you plan to start your own business and do this project after graduation?"

Lin Chen shook his head, "I don't plan to start my own business to do this." College students start a business or something, it looks very good, in fact, hehe. Bill Gates dropped out of school to start a business because he was covered by a mother who was an executive at IBM. I'm still going to be in an advanced company to gain some experience. ”

Another turn almost flashed Zhao Xilin's waist, although he knew that the lumbar intervertebral disc was normal, he couldn't help but hold his waist with his left hand and asked, "Then what are you going to do?"

"Make a smart aircraft tube, but not by yourself, but by this. Lin Chen said and opened the browser, found a link called "Bee Flower Hunting Plan" on the home page of the bee navigation and clicked on it.

"I'm going to invest this project in Bees and earn back the money I spent here for the internet. ”
