Humans yearn for flying, and so does Lan Zeguang, although she will use the air to lift her body and fly, but what about others?

At present, the quadcopter aerial photography drone is very popular, because it is not only a flexible shooting platform in the air, but also can become a variety of unexpected equipment after a little modification, equipped with other equipment. Let's take the simplest example: hang an explosives bag, that is, it is a cruise bomb controlled by a person.

Lan Zeguang can't make bombs, but he thinks that after the quadcopter is promoted, it can be of some help in the collection of souls.

To this end, Lan Zeguang made a quadcopter, and the aircraft was intermittently made for more than a week, and it was ready to be able to carry out a test flight. But tonight, Lan Zeguang sent out: his own aircraft had been moved. Lan Zeguang picked it up and shook it in front of his eyes, and found that the gyroscope and electronic compass on the aircraft had been removed by others.

In the real room, there are some more valuable parts that are the property of the real room, such as gyroscope modules, GPS modules, electronic governors, brushless motors, etc., which are all things that the real room bought back from the school for funds to be shared by the real room.

These things are not precious to Lan Zeguang, but fortunately, if you want to use them, you can apply to the teacher in the real yàn room, and you don't need to go online to buy and wait for the arrival of things.

But it is precisely because of this that it has become the fuse of another conflict.

"Oh my God, I'm a pretty girl now, and that senior is always against me, he's a, right?" Lan Zeguang was not too angry about this, and she put the flying machine down. Said with his eyes covered.

"Huh? Lan Zeguangsang, what's wrong with you, don't you do this thing called a quadcopter? As an outsider, Lucifer didn't know what was going on. Lucifer came to see philosophy. If Lan Zeguang needs to do something seriously and doesn't want to be disturbed, Lucifer will quietly read next to him.

"It's not that I don't do it, something has been torn down." Lan Zeguang sighed.

"It can't be another senior, right?" Lan Zeguang was not angry, but Lucifer was not happy when he knew that someone had broken something Lan Zeguang had made.

"I probably know, Lucifer, you read your book, I'll look for it." Take Lucifer's urine. Lan Zeguang knew that he would definitely take people out and teach them a lesson. Lan Zeguang felt that these seniors who consciously competed for learning resources were the future pillars of the motherland, and they should not give Lucifer a scourge, so he wanted to say it calmly.

She first found the resident teacher in the real yàn room. This is an old professor who spends his days tinkering with wireless communications, and for this purpose he also led the creation of a project for the new school. At the same time, this teacher is also responsible for managing the resources of the real yàn room. Modules like gyroscopes, which cost nearly a hundred dollars, belong to the "more expensive" line. I have to ask him for it.

"Professor Peng, what about the piece of MPU9150 I took yesterday?" Lan Zeguang is not shy about reporting professional terms. The so-called MPU9150 is the name of a nine-axis gyroscope. It is able to provide acceleration, angular velocity, horizontal attitude and other numbers, through guòSPI bus transmission, the refresh rate can reach 500HZ, which can fully meet the control of a quadcopter.

All right. Much gossip, anyway. That's a big deal.

"Oh, Lan Zeguang." Professor Peng has some appreciation for Lan Zeguang, a freshman. Last time, she got a simple railgun that instantly released energy and fired a copper bullet that could break through a wooden plank. At this stage, the energy release and storage of electromagnetic guns are research topics today, and it is not easy for a freshman to do this.

In fact, regarding the energy storage of the electromagnetic gun, Lan Zeguang chose several large capacitors to store it, and made several levels of acceleration coils to ensure that the input current and voltage in an instant meet the initial velocity of the electromagnetic gun. Of course, this is only when discharged with ordinary capacitors, which can crack a few millimeters of wood, but in fact, if Lan Zeguang wants to cheat......

At that time, it was necessary to consider whether the temperature generated by the friction between the bullet and the air would dissolve the bullet. Because using the power of the soul and cooperating with perception to directly drive the flow of electric current, a huge electric current can be created in an instant.

Therefore, Lan Zeguang's coil cannon is a weapon, and he is exactly as long as a submachine gun. No, in this era of gun control, being able to make a powerful weapon by yourself is a capital for self-defense.

In case a demon comes from the Otherworld, Lan Zeguang is sure to defeat it with a coil cannon he made.

Now, though, is not the time to care about coil guns.

"Your MPU9150 I asked Senior Dong Chen to take it, and so did the electronic compass. I don't think it's a good idea to get these things before you have access to C yet, so let's learn C first. Although you are very good at hardware, you still have to start all over again in software programming......" The old professor grunted as he fumbled with his things.

Then he made the old mistake, pulled Lan Zeguang and said: "Look, this FDOM antenna has no program to cooperate......"

"Wait, wait, wait!" Although a little disrespectful, Lan Zeguang interrupted him. Some things must be explained: "Professor Peng, who said that I don't know C anymore, do you want me to draw the transmission sequence diagram of the SPI bus used in MPU9150 to show you......"

“…… Alas? Being asked by Lan Zeguang like this, Professor Peng immediately became too strong.

"You know, when did you learn it?"

"You don't have to worry about that, do you...... Can I go and get the 9150 back? Lan Zeguang knew the hieroglyphs that were noisy with the old man, so he said straight to the point.

"Yes, yes. But be careful, if your plane gets out of control, the propeller will hit your cute face in trouble! ”

"Yes, yes, I'll be careful!" Lan Zeguang smiled dryly. Speaking of which, the quadcopter is in this real room, and because there has been an accident, few people play it. And that accident was precisely because when a senior was debugging the aircraft, the attitude number of the gyroscope changed for no reason, and the aircraft that was supposed to be in the critical state of starting suddenly started, and then a bloody case occurred.

Of course, the legend of this room is that Lan Zeguang has not seen it, so in the spirit of "he is powerful", Lan Zeguang is determined to try the legendary quadcopter as well.

Gossiping, Lan Zeguang quickly found the senior named Dong Chen. Like the impression of many program apes, this senior is a sloppy guy, with an unshaven beard, unshaven hair, and often comes here in tasteless Taobao 50 free shipping clothes. When Lan Zeguang walked behind him, he saw that he was compiling the program, and while the program was compiling, he was browsing a website.

The name of that website is ......

Acfun。

So this senior is an acer, in other words, he doesn't have a girlfriend!

In this era, it is really commendable to be able to focus on learning and complaining, and not close to beauty. In this regard, Lan Zeguang admired him very much in his heart, because he was the only one who dared to contradict himself. Thinking about this real room, most seniors will let themselves do this, only this senior named Dong Chen is hot-blooded, and it is unpleasant to see Lan Zeguang seize the resources of the real room.

- Of course, he must have faced Lan Zeguang with a contemptive mentality.

If the design ability of hardware circuits is strong, it can prove that high school physics is good. After all, Lan Zeguang's first work: the schematic diagram of the electromagnetic gun is so much on the Internet, Lan Zeguang found a model modification of the 95 rifle, which is not big news.

Come to think of it, this thing doesn't even have to draw a PCB or circuit diagram. The only thing to admire is about the processing of abrasives.

However, this is still not difficult for Lan Zeguang.

After all, there is mental power, and any corner that is difficult to process can be solved.

Well, it seems that strange things are said again. Lan Zeguang sympathized with this senior who deserved to have no girlfriend, so he was not angry at all at him for taking what he borrowed, and stood behind him. And another senior next to him found Lan Zeguang and hurriedly smiled at her and made a good impression. Then he pulled Dong Chen:

"Hey, Dong Chen, the senior sister is here!"

"Yo!" When the senior named Dong Chen heard Lan Zeguang's arrival, he immediately turned his head in a weird way and said, "Senior sister, what do you have to do with me?" ”

"Professor Peng said that you took my MPU9150, have you done your research now?" Lan Zeguang asked calmly.

"I can't read this thing yet, can you?!" As soon as it came up, it was ridicule, Lan Zeguang covered his mouth and smiled, and said, "Where can't I read it?" ”

To talk to this kind of scheming dead otaku is to cut the topic to the point. Although Lan Zeguang has not used MPU9150 this chip, he understands the communication method called SPI protocol required for the processor to communicate with him.

"I don't know, there's no problem with SPI." Sure enough, as soon as Lan Zeguang asked, the senior's attitude was good.

"Can I take a look?" Lan Zeguang continued to ask.

"Do you understand?" Dong Chen seemed to be very disdainful.

"I don't understand what I'm doing senior?" Lan Zeguang looked like he took it for granted, and then simply squeezed him aside with manly force and held the mouse. Then, I immediately found the problem: "Hey, senior, your mailing address is wrong!" ”

"Can I take a look?" Lan Zeguang continued to ask.

"Do you understand?" Dong Chen seemed to be very disdainful.

"I don't understand what I'm doing senior?" Lan Zeguang looked like he took it for granted, and then simply squeezed him aside with manly force and held the mouse. Then, I immediately found the problem: "Hey, senior, your mailing address is wrong!" (To be continued......)
