Overturned? Or the romance of the polytechnic man?

He classmate, isn't it "hot search physique"?
This is not just yesterday after the update of the video work, the entry #He Classmate # appeared on the Weibo hot search list, and finally stopped at the 4th place, and even with a small tail "boiling" behind.
Incomplete statistics, this is already the 7th time that He classmates have been hot searched for because of their works, the last time was because of "homemade AirDesk", this time he used 108 days, and what new things did he do?
In order to turn on and off the lights, He made a "sense of ceremony"
At the beginning of the video, He first expressed his liking for the studio environment, because there are 5 3D printers, an organic soda cabinet next to the table, a lifting table for all employees, and a smart coaster he made for everyone.
According to the introduction of He, from the moment the water cup is put on, the coaster with the appearance of "straight male powder" will begin to count down, and 2 hours will begin to call "drink water ~ drink water ~ go to give me water ~" until the cup is picked up. Of course, if you don't want to drink water, and don't want to continue to wear the magic sound through the ear, He also gave a shortcut button, and you can turn off the water prompt sound by smashing it.
Seeing this, I think there must have been a lot of people planting grass this smart coaster. Perhaps soon after, a certain treasure will have the same classmates.
Continuing to return to the main topic, it can be said that He is satisfied with where and where his working environment is, and the only point of dissatisfaction is that the workstation is far away from the switch panel of the lamp, so that every time the light is turned on and off, you need to walk over and walk over.
In the words of He, this way of turning on and off the lights is really "too stupid".
So, with the thought of "how to turn on the light when sitting in a seat", he moved.
First of all, using half a day of modeling, printing, assembly and other operations, He students installed a large switch on the original switch, and by the way, installed a basket, so that He students can shoot the switch light.
But unfortunately, He's motor nerves do not seem to be very developed, thrown several times tennis ball can not accurately hit the big switch, and finally he found a pet ball throwing machine, but unfortunately, the pet serve machine whether it is placed on the ground, or on the workstation table, its launch force can not project the ball into the frame, even the edge of the frame can not be touched.
No way, He spent half a week modeling, printing, assembling, and finally got a "He Classmate desktop light throwing machine".
Experiments have proved that this ball throwing machine is still very useful. He only needs to put a tennis ball in, and the machine can accurately project it out, and accurately hit the big switch, and can turn off the lights without leaving the seat.
At this point, this video ends (and is not).
The next second, He issued a "too stupid" exclamation for the second time, the reason is that the ball was thrown, but if you want to throw the ball again, you have to pick up the ball that was thrown first, compared with directly walking over to turn on the light, everything is back to the original point.
How can we form a closed loop? He thought of the machine trolley, which can use the mechanical arm to clip the tennis ball after recognition, transport and put it on the lifting table next to the workbench, and then the lifting platform automatically rises and sends the ball through the track into the ball throwing machine.
However, the ideal is full, but the reality is bone-
It took another two weeks for He to repeat the third modeling, printing, and assembly, and got a small car. At this time, new problems have also emerged, the car identification, picking up / putting down the ball is very simple, but in order to accurately put the ball on the lifting platform in a complex office environment, it is also necessary to model the positioning system, patrol obstacle avoidance system, and more importantly, to be able to charge independently, after all, "the kung fu of changing a battery is enough (He Classmate) to turn on two hundred times the lights."
"It's clearly beyond my level." He students were helpless to sigh.
But giving up at this time is not the consistent style of He Students. Since starting from 0 is beyond the scope of ability, it is better to change now, so he found a sweeping robot, which can not only model and locate indoors, but also has the function of patrolling obstacle avoidance, but also can charge itself, sweep the ground by the way, and get more in one fell swoop. (There are "hidden Easter eggs" here)
At this time, from pitching switch lights to tennis ball recycling, the closed loop of the system of "sitting on and off lights" is realized.
Seeing this, He's problem seems to have been solved, but the progress bar that has not yet passed the half tells us that things are not so simple.
Sure enough, in the next second, he issued a "too stupid" exclamation for the third time - the lifting table destroyed everything, and once the table was raised, not only was the ball thrown inaccurately, but the lifting table could not pour the tennis ball into the throwing machine.
In fact, it is very simple to solve, let the throwing angle of the ball throwing machine change with the height of the table, and then redesign the tennis lift table. But He was biased, because he realized that "you can use all the things you learned in this project to make an ultimate version of the light polisher." ”
Simple understanding, and then "tossing" is finished.
So after the desktop version of the ball throwing machine, He launched all 5 3D printers in the office, spent 6 weeks modeling, printing, assembling, and programming, and finally got an "ultimate handheld automatic alignment light throwing machine".
Halfway through, in order to make this handheld ball thrower able to project at the basket in a lighted/unlit environment, He first placed an infrared light above the switch, and then replaced the original ordinary camera of the ball thrower with an infrared camera, so that the handheld ball thrower can lock the basket position at any angle. He also solved the fourth new problem that made him sigh "too stupid".
At the same time, He also installed a distance sensor under the infrared camera to measure the distance between the handheld ball thrower and the wall where the switch is located (the distance between the ball thrower and the ground is relatively fixed), which is convenient for the ball thrower to adjust the throwing angle.
As for the problem of picking up the ball, He first placed 4 positioning base stations in the studio, and installed a positioning sensor on the handheld ball throwing machine.
During the specific operation, the sweeping robot still picks up the ball and puts it on the table tennis lifting platform, which is then responsible for transmitting the tennis ball through the track to the desktop auxiliary thrower. At that time, the 4 base stations will send the position of the handheld ball throwing machine to the desktop auxiliary ball throwing machine in real time, if He students need to switch the light, just need to press the button on the handheld ball throwing machine, and the desktop auxiliary ball throwing machine will accurately project the tennis ball to He students at a safe speed.
After such a set of processes, who can not sigh: this damn sense of ceremony!

Overturned? The romance of a polytechnic man? Netizen comments are polarized
In fact, watching the entire video, presumably there are also netizens who have sent out a soul question: Why not install a smart socket directly? Or do you want to make a simple steering gear device? Instead, it took a lot of trouble to do so much in 108 days?
It can be seen on the Internet that there are many people who hold this view, believing that this video is only for the sake of eating, and he students have lost their original intentions:
In fact, in the video and introduction, He also guessed that it would cause doubts, and responded in the video:
For such a long time, I have not turned on the lights for a long time, it is my dream of becoming an excellent DIY district up master.
In this regard, many netizens also expressed their support:
In this regard, the author feels that these two comments are still quite pertinent:
What do you think?
One More Thing！
Remember the effect of the last "Homemade AirDesk" video after it aired? The market capitalization of customer companies increased by 600 million yuan.
This time we see that the protagonist of this promotion can finally be found to be Coworth. It's just a pity that it is the Spring Festival, A shares are in a state of suspension, if not, we may be able to witness the "power" of He's video again.
