MTL - The Black Tech Life of Scum-Chapter 2 : Zhang Yifan's troubles

The night in the village is as quiet as it always is, except for the vocal shop in the village entrance.

It's eight or nine o'clock already. At this time, almost every household is closed.

In addition to the store, there are also people playing with small cards.

In small villages, there are only dozens of households. This business still needs to be developed in the neighborhood,

Say no to anyone who has no smoke at home and is addicted again, come out and buy a pack;

Who is not who, say that the guest is here, the drink is not enough, come and carry a few bottles;

Put a TV inside the shop, and then set up a table, attracting people to play cards and bragging;

I ca n’t say that I can sell some drinks and food, and I wo n’t lose anything if I do n’t buy it. Just adding popularity is a marketing strategy;

So the whole village is quiet ...

Zhang Yifan stretched his arms. This kind of tranquility was his favorite time. He lit a cigarette and then turned off the power of chrome.

然后 Then, put two drops of water on the board that was just assembled ...

Looking at the two mechanical arms that have been stretched forward, they slowly retracted, Zhang Yifan smiled:

"Success!"

In fact, what Zhang Yifan did was just a simple rainwater detection drying rack.

In addition to the transmission mechanism that makes the action, the main components are the induction device and the CPU;

配件 These accessories were all dismantled by Zhang Yifan in the waste recycling bin of his classmate Wang Beibei's home. No money.

Induction wipers for cars are actually three ways;

The first is a resistive sensor, which is an inductive method that uses rain drops on a positive and negative copper-clad copper plate and then detects the leakage current to make an action.

The second type is a capacitive sensor, which is designed by using the huge difference between the dielectric constants of water and glass. This technology is also used in automobiles, but it also has disadvantages.

The third type, which is the most mainstream sensor, optical sensor;

Optical sensors are actually similar to radar in principle, but one belongs to radio and the other belongs to light;

It is nothing more than using a light emitting diode to emit a beam of light, and then calculating whether it is raining and how much rain is based on the light received by the receiver.

This optical sensor is very accurate, and it is even possible to accurately determine the number of raindrops falling on the area being sensed.

Zhang Yifan has debugged many times and found that the resistance sensor and capacitor or sensor play a more significant role in the drying rack he designed.

The reason is very simple, because it does n’t matter how heavy the rain is when you dry your clothes.

The rain is not clean. The washed clothes get wet during the drying process. The possible result is to wash again ...

As soon as the sun is finished, it doesn't seem important at this time.

This thing is to solve the problem of collecting clothes in the rain, but not anything else.

How about drying it again?

擦 Wipe the sensor clean, then activate the clothes button, the whole shelf is pushed out again, it is simple and convenient.

Zhang Yifan came up with this thing for a simple reason:

I was Zhang Ma once, everyone was working in the farm, and then the weather was not good, and the mother brought him back .... It rained home to collect clothes ...

I walked several miles to the road, and before it got home in ten minutes, the rain came down. I did n’t go to the village before, and I did n’t go to the store afterwards.

When I got home, all my clothes were soaked. Of course, the clothes on my body were not much better ...

So Zhang Yifan didn't go out for several days just to make this thing.

"Yifan, I'm going to bed, you remember to feed the dog before going to bed ..."

Suddenly there was the voice of his mother Huang Xiujuan outside the door.

Zhang Yifan could not help but responded loudly.

Later, he felt that his life was so meaningless .... It was either collecting clothes or feeding dogs.

Zhang Yifan's spirit is: do n’t sit when you can lie down, do n’t stand when you can sit, and do n’t move when you are standing. In fact, these trivial tasks are repelled in my heart.

Feeding the dog is not too much trouble, mix leftovers and leftovers, and pour in the dog bowl;

Alas, it's always a troublesome thing, the feeder, he has not done it,

水 The water feeder made from the drink bottle and siphon principle, and the dog food feeder made from the Sprite bottle, did not last long;

The dog that the family raises is a Chinese pastoral dog, which has a strong bite force. The important thing is to be smart. The newly added device will be removed in two or three times ...

The situation at home, Zhang Yifan is not unaware, but there is really no way ...

I know why, what kind of language and things are big when I look at it;

And, I do n’t know when it started, and my mind started to mess ...

比如. For example, in mathematics, there is always a consciousness to tell yourself that this is the right way to do it, and then naturally, or that the teacher had to be put aside as a last resort ... and then miserable

It is not that He has not rejected those ‘answers’ that God knows where to come from, but it ’s completely ineffective, it is still so deeply ingrained that he accidentally affects himself ...

Especially when doing some repetitive work, I will feel a headache, obviously, it is something that does not require much brain at all ...

This problem has troubled Zhang Yifan for a long time ....

For this reason, while studying in the Vocational and Technical College, Zhang Yifan even secretly went to the hospital to take a brain CT, and wanted to see what went wrong in his mind. However, he found nothing, but only spent a few hundred dollars. Take a few breaks and drink more water ...

Later, I just stopped there. If I wanted to go to the psychiatric department, Zhang Yifan was a little bit cold ....

Anyway, there is no pressure to study in the vocational college. Many students' minds are not on study, and they are more time-mixed.

In Zhang Yifan's view, there may be two villains in everyone's mind;

In Xue Ba's mind, one of them should say to study hard, and the other said, ‘Oh! Brother, I listen to you! ’

In the minds of ordinary people, one said to study hard, and the other said that they wanted to play ~ www.novelbuddy.com ~ Then, there are usually winners and losers;

And his own is completely different:

One said: Do n’t learn, you are born to do big things;

Another said: Yes, we are more committed to solving problems, and we have a better way to solve these small problems .....

So, after three years of college, Zhang Yifan did not accomplish the important thing, but he also made a few things:

For example, teachers use voice recognition technology to report by name-for skipping classes;

的 Wind-powered and human-powered generating units hanging on the balcony of the dormitory-backup power supply for power failure after 11 o'clock;

Modified drones—used to prohibit fast food delivery outside the campus to take food to improve food;

Uh ...

These things seem to belong to repeated design, and have the same effect as the peasant-built helicopter, and who knows the effect;

For example, a certain member of the ranks bravely reported the bad behavior of someone who was still sleeping in the dormitory, and then used electronic devices to cheat the roll call mechanism;

For another example, roommates forgot to play LOL and forgot their time. When the dormitory was powered off, they never forget to let Zhang Yifan run to the balcony to give them hand-cranked power to ensure that they do not pit teammates ...

However, even with such defects, Zhang Yifan is very fulfilling ...

Of course, these things are not useful to a vocational school student who majors in auto repair ....

After receiving the instructions from my mother to feed the dog, Zhang Yifan's mind calmed down and began to regain his vitality ....

Yes, I should get an automatic dog feeding device .... how much annoying to feed dogs every day ...

Zhang Yifan took his habit of thinking and started his work ...
