Metropolis: a big treasure chest every week

Chapter 2 Don’t worry, the college entrance examination champion must be mine!

After brushing up on the topics for two hours, An Jing ended Sunday’s study boringly.

There is no need to brush up on the questions.

Such a brain, brushing the questions also does not have any experience, there is no challenge.

Leave the study.

An Jing returned to his room, looked at a model aircraft placed in the room, opened a delicate small box, and began to tinker with the model aircraft.

Only about 20 cm of “J-20” model aircraft, using batteries, is indeed a model aircraft, not a drone.

The key is that all the parts of this model aircraft were made by Anjing himself, and it took half a year to do it.

Mainly because of the college entrance examination, and the later it goes, the pressure is also great, and I can only take very little time to go to my father’s processing factory to make parts.

Now the college entrance examination is stress-free.

Brushing the question was also boring, and An Jing tinkered with his flight film.

Boys don’t like Barbie.

It’s guns, planes, robots, supercars, beautiful women.

An Jing also likes guns, but that thing is either controlled or prohibited from manufacturing and processing, and can only be used as a model aircraft.

It is more troublesome for the robot to move;

Supercars can’t be done unless they are also models;

Forget about the beauty… I don’t have that thought, I’m only eighteen years old, and the college entrance examination is more important.

The model aircraft was taken out, disassembled, and debugged.

After all, if left there for a long time, it is inevitable that it may bump, and the parts inside may loosen or even fall off.

This is just Anjing’s game, and it may not even be comparable to those toy model aircraft on the road stall.

The remote-controlled toys on the stalls are also down the assembly line.

An Jing assembled the model aircraft, and then took the chip decoder to the study and wrote the code to control the chip.

Model aircraft manufacturing is not very difficult, design and calculate the appearance, weight, power, make the parts, assemble them, install the battery.

It is more difficult or how to control.

This is also the reason why the model aircraft was lost there for half a year.

Previously, An Jing also turned over a lot of programming knowledge, thinking of becoming a hacker and crisscrossing the network, so he taught himself programming.

However, programming this thing is indeed a little difficult, even if An Jing is a top student, he is also good at mathematics and science.

But facing the college entrance examination, the second half of the third year of high school will be abandoned.

Getting him to write a program for a remote-controlled aircraft is still a bit difficult.

Now well!

The brain mobilizes the programming knowledge previously learned, and even the programs that have been designed and thought about before, and the powerful brain calculates, organizes, and optimizes.

Tapping rhythmically on the keyboard with both hands, different codes are written and entered into the chip.

After more than ten minutes, An Jing got the code.

Then install the chip inside the remote control.

At this time, the button to operate the remote control will be translated into a set code and transmitted to the radio receiving module of the J-20 model aircraft through the radio transmission module on the remote control.

“Uh-huh? How not to work?! ”

An Jing wrote the program, installed the chip, took the remote control and the model aircraft downstairs, and found a place outside the community where no one could try to see if he could fly.

As a result, the buttons for takeoff, forward and backward were pressed, all useless?

“Is there a problem with the programming, or the chip, or is the power unit sitting for too long?”

“Oh~ The model aircraft does not have a battery!”

I was stupid enough to cry by myself.

An Jing hurriedly went to buy a row of Nanfu batteries and installed them on the model aircraft.

Turn on the switch.

Control the remote control!!

Buzzing!!

After the motor is energized, the motor drives the gear, generates power, and makes the model aircraft fly… Then, after flying two or three meters, he fell to the ground again.

There was a “bang”.

The model aircraft was directly torn apart, and parts were scattered on the ground.

“It’s not interesting, it’s still heavy, the battery can’t be brought up at all, and the motor can’t be carried out, unless you make an engine, and then use fuel and batteries, and then adjust the fuselage… But this is done, maybe more than half a meter, right? ”

An Jing doesn’t need to look at it, he knows what went wrong, and how to modify it can solve this problem.

This was still made half a year ago, and I still remember it well.

Now go back and look at it, a bunch of faults can be easily found.

Time also does not allow Anjing to create another big fellow.

More than half a meter, seventy or eighty centimeters of model aircraft, plus an engine, with batteries and fuel, then it must be a big guy, can fly very far, as a drone can be.

However, if you really abandon the shell of the J-20 and make that mode of multiple robotic arms, it will not be too difficult to fly.

The appearance of the J-20, it is still difficult to fly.

Pick up the parts on the ground, and when you get home, you throw them aside to eat ashes.

I took out my phone and read the message.

An Jing has good academic performance, self-discipline is naturally high, and he has little dependence on mobile phones.

The communication between the senior students is directly asked, and no one brings mobile phones.

Now I don’t go to class, I am preparing for exams at home, and students have mobile phones to communicate.

In fact, there is not much communication.

Occasionally send a message on WeChat.

An Jing took a look.

The head teacher sends some news every day to prepare for the exam, reminding everyone of some precautions, don’t be stressed and so on.

Everything else is asking questions.

An Jing generously explained the solution ideas and answers to these questions.

Moreover, there is more than one problem-solving idea!

It has led to a lot of discussion.

There are more people, leading to other students.

The WeChat group soon became active, and the news was instantly 99+!

After all, they are all in the first class, and their grades are not too bad, and they are all students who have steadily passed the key line.

“Can this problem still be solved like this?”

“An Jing, have you ever done this question?”

“You may have encountered a problem, but you can’t have done more than a dozen, right?”

“An Jing’s problem-solving idea is very good, and this kind of solution can also be thought of, although it is a little troublesome, it is also a problem-solving idea. You can understand that in a specific question type, this kind of thinking has advantages, and it is easier to remember and master. ”

“Anjing or go play quietly, come out and hit people… Crying in the toilet. ”

“Can’t catch up, can’t catch up… It seems that during the usual test, An Jing still hides his strength, this time he will take the college entrance examination, come out and pretend to be forced, very sullen! ”

“An Jing has been in the throes for thousands of years, dominating the rivers and lakes, and we in Shuwai will definitely win the science college entrance examination this time!”

An Jing’s strong competitor was in the group, and began to ridicule him, very bad.

An Jing suddenly became so powerful, there are many solutions to a problem, many people did not expect this kind of thinking.

Even the teacher felt that An Jing’s thinking was very peculiar.

Although some solutions are more troublesome, they are also a solution.

An Jing: “…”

These students talk so well that they want to continue the water.

However, time does not allow, help solve the problem, discuss collective thinking with teachers and classmates, time flies quickly, it’s time for lunch!

In the end, An Jing still dropped a cruel sentence: “Don’t worry, the science champion must be from outside our Shu!” ”

Although An Jing did not directly say, the champion of the science college entrance examination must be his.

But everyone knows that these two sentences mean the same thing!!
