The talented people in Jiangshan have put together a variety show

Teacher Fu Tao had a good impression of Vacation.

He came to the show, mainly for fun.He usually likes to make handmade things, and he happens to know some related knowledge.I have already retired, so many programs can be shown if I want to, or if I don’t want to.It's okay, just come and come.

Before coming to variety shows, he actually knew a lot about variety shows.There is still a gap between the real picture and the understanding.But he also knows that the dialogue between the two people in the room now has a variety show effect that is far greater than reality.

Even if some of them really don't understand it at all, it won't hold back too much when shooting it.

Teacher Fu Tao cooperated with the camera and made a rather shocking expression.

He Jun and Ye Hao really didn't know that Fu Tao had arrived outside, and they were still listening to the two of them talking.

He Jun showed Ye Hao the drone he designed: "Look, I made a Vacation logo sticker on the casing. I just put it on after I finished it. There is a spare one here, and you will put it on later."

Ye Hao accepted the logo, but he said honestly: "I don't think my machine can be put together. I guess it will really be a model by then, and it is not useful. The last day will blow up the machine."

He Jun smiled indifferently: "Use my experience in programming class. You just have to face it calmly that you don't know how to do it. The teacher really doesn't catch your eye, and will help you finish your work." And there is a certain probability to tell you, in fact, you have some content What you are doing is useless work. It is just a bit more ritualistic to do it yourself from beginning to end. In essence, you only need to copy and paste.

This is completely different from the way they usually sing and dance by themselves. After all, they are the ones on stage.

Ye Hao lowered his voice, full of expectation: "Really?"

Fu Tao snorted, opened the door and walked in: "Fake. I remember. If you don't know how, I will give language guidance next to you, and I will never help you."

He Jun and Ye Hao didn't expect to be caught on the spot, so they stood together and shouted guiltyly, "Hello, teacher!"

Fu Tao snorted a second time: "It's not good at all. It's okay, let's start working directly from the panel today. Let's classify the drone's propellers."

Ye Hao secretly glanced at the captain, and asked sincerely with his eyes: Captain, which panel is it?What is a panel?Is it the biggest one?

He Jun slowly took out a board with four corners and put it forward, for fear that Ye Hao next to him would not be able to see it.He easily separated the propeller and put it in a more conspicuous position.

The barrage laughed wildly: "Hahahahaha, this is the point of being a good student at the same table."

"I'm dying of laughter, Ye Hao copied the answer like crazy."

"Ye Hao: No one told me that I'm going to fight this thing today!"

Fu Tao saw that Ye Hao was really not good at it, so he stood beside He Jun, and simply told He Jun first, so that Ye Hao could learn how to put it together: "First install the electronic components. Then install the motor. "

He Jun studied and installed the parts on the chassis one by one.

To be honest, most accessories are very light, and the battery really accounts for a large proportion of the weight.During the installation process, it is necessary to control the subsequent weight balance.Otherwise, the plane will crash in the sky.

During the process of pretending, it was impossible for the three of them to stand all the time, so naturally they sat down and got busy.Fu Tao didn't know where to find a very thin stick, and used this stick to guide He Jun: "It's stuck here, yes."

Ye Hao was frantically stealing from the side.See what the captain does, and then come back and study how you spell.

Fu Tao didn't let Ye Hao go, and found something wrong with him, so he directly poked Ye Hao's hand with a stick: "Stop, stop. Do you want to twist the twist in the drone with this circuit? Straighten it out."

Ye Hao was innocent, weak and pitiful, so he straightened out the wires and reinstalled them.After assembling, he tried to quickly follow the captain's operation to continue assembling, but because he was a little too slow, he could only shout over there: "Wait, wait, captain. How did you take that step just now?"

He Jun watched Ye Hao's progress and guided the assembly.

Then install the flight control board, add the programming card and display, calibrate the sensors, configure the motors, install the propellers...

The fascination of science and engineering is quite different.Serious people, regardless of gender, will have a charm bonus.

After the camera speeds up, the rough drone with no casing is barely installed with most of the accessories, and finally figured out the most basic form.Fu Tao took the two for the first test flight.

The altitude of the test flight was very low, and Fu Tao reminded first: "You two, don't fly too high, or you will suffer heavy losses if you fall. If you break, you have to start all over again."

He Jun and Ye Hao responded immediately.

The camera shifted to the drone, and I saw two drones with different shapes and attributes taking off tremblingly, and flew to a height of about 20 cm from the table.

Fu Tao's eyes were sharp, and he directly gestured with a rope with a heavy object hanging on it.Being able to form a right angle means that the drone is quite stable.Failure to form a right angle means that the drone is completely unstable, and the installation weight is unreasonable, causing the drone to tilt.

He Jun and Ye Hao then fine-tuned the drone they assembled.

By the time they flew again, the two rough drones, with their lines still exposed, finally reached the point where they met Fu Tao's standards.Fortunately, the two were careful during the operation and luckily, there was no crash at all.

At this time, the two installed the casing on the drone.Only the internal drone can be used, but the aesthetics is not enough.The shell has been treated long ago and is in a state of exterior paint.After the shell was set, the two debugged for a while, and finally added stickers.

After the Vacation stickers were pasted on, the two drones immediately looked like they were flying freely in the classroom.

He Jun recalled the internal structure and couldn't help but be sure: "It is necessary for the product to have a good-looking skin. Even if it is just an ordinary drone."

Ye Hao followed with affirmation: "A pen refill costs 16 cents, plus a regular casing for [-] yuan, and a dream-colored transparent casing can be sold for [-] yuan. If you add a dreamy name, you can sell it for [-] yuan."

He Jun looked at Ye Hao in surprise: "You are very proficient."

Of course, Ye Hao said humbly: "Teacher Tong Wenle taught well. People who do business are different after all."

The bullet screen was full of question marks, and after careful thought, I found: "??? It seems to be true!"

"Don't ask, the question is how to sell a glass from 5 yuan to 180. It all depends on some gimmicks."

"The center of the world is Yiwu Small Commodity Market!"

"Hahahahaha, the front is going to kill me laughing."

Seeing that both of them had succeeded, Teacher Fu Tao left the stage happily. Before leaving, he invited them to play with wood at his place.He also makes wooden drones.Of course, this kind of drone is mainly for self-play, and there is not much marketability.

Of course He Jun and Ye Hao agreed.

Ye Hao passively learned the assembly of drones, and continued to happily learn about paragliding, while He Jun rethought the drones for plant protection.If you don't do it, you don't know. Only after doing it, you will find out the problem of the drone.

He also said directly to the camera: "I have been learning to make electric drones during this time. The batteries are very big when they are assembled. It feels like the whole piece in the middle is a battery. If the drone wants to fly While spraying pesticides, the power consumption will be staggering. Because the use of plant protection drones in agriculture is for fertilization, and the load-bearing requirements are high.”

"It's like an airplane takes people to the sky, and the energy consumption is very high." He Jun dug out the information he checked, "Actually, most passenger planes on the plane do not have skydiving equipment. Because once every passenger has a skydiving equipment, the weight of the entire airplane will be reduced." will increase, and the demand for dye will increase.” Not everyone can skydive.And if only a few umbrellas are left, no one dares to bet on humanity.

"The same is true for drones. The higher the load, the faster the power consumption. Generally speaking, it takes about ten to twenty minutes for the plant protection drone to fly. Then it has to be charged. In the early years, it was charged for one hour and lasted two 10 minutes. Now there are extremely fast charging, about 10 minutes of charging, lasting for 10 minutes."

Not to mention He Jun, the audience felt that the energy consumption was fast after hearing it.

Such a high-energy-consuming drone is still used at such a high rate today. He Jun also explained to everyone: "Because a skilled pilot can handle an acre of land in one minute, drones are used in agriculture to solve many problems. The problem must be a general direction of development. The researchers must also be developing in this direction."

He Jun looked up various materials on his desk: "The problem of electricity is actually a big problem with many devices. For example, new energy vehicles. This also uses electricity. New energy batteries are actually a hardware breakthrough direction. Alternatives such as solar energy and hydrogen energy are less popular.”

The weak popularity is naturally due to reasons such as high costs.

The audience couldn't help but nod.

Like mobile phones and portable tablets and laptops, everyone hopes that the battery will last longer.Anyway, don't go out and charge the battery three times a day.Especially for those who are keen on playing games, the battery of the mobile phone really cannot afford to spend a few times.

He Jun thought for a while: "Now there is wireless charging technology. Some people also proposed a way. If it is said that solar energy can be absorbed and then converted into electrical energy, then wireless charging technology can be used again to allow new energy vehicles to charge while driving. Of course We have repaired roads before. The road surface has load-bearing requirements. It will also wear out, so how to reduce the cost and eventually popularize requires research and development and time.”

He sorted out the content and brought the topic back to drones: "Now drones, like sweeping robots, can automatically return to the voyage to charge. If we talk about future agricultural development, there can be fast wireless charging equipment at fixed points on farmland. It It will be able to fly in the air all the time. When refilling the medicine, there is also a period of time for fast charging.”

Barrage: "!! I suddenly recalled when Vacation was working on patented inventions in Happy Farm."

"Goose bumps came up, I actually think this method is very reasonable."

"I just want to ask Captain He, why didn't he engage in research and development back then. This brain is really..."

"Don't ask, he just likes the stage. To be honest, he is the one in the team who is most dedicated to the stage."

Under He Jun's description, almost everyone can imagine the agricultural world in the era of complete mechanization.That is really almost out of manpower, relying entirely on mechanical automation for one-stop operation.

After talking for a long time, He Jun put his eyes on the drone he made, and smiled gently: "Let us try to modify this drone."

Audience: "Huh? Wait, has this become a technical variety show?"
