We Live In Nanjing

  Chapter 77 Binary Strike the Mandible

In the afternoon of the day, the girl was still pouring the motherboard. The motherboard, which has been placed in a humid climate for 20 years, is simply a mold petri dish, with brightly colored hairs. At first glance, she thought it was a paint palette. Clean them up and put them outside in the sun. Wang Ning said that it is best to find motherboards that have not been opened and unused. Industrial control or military motherboards are best because they use tantalum capacitors, which are not easy to break.

   "For the 3150 industrial control motherboard, I think it should be possible to find a Celeron 3150 fanless industrial control motherboard." Wang Ning said, "This thing is very easy to find on Zhujiang Road."

  "Have you used that thing?" Bai Zhen asked, "What system?"

   "XP, or Win7." Wang Ning replied.

   "Very good." Bai Zhen nodded, "That can be a red alert."

Pinellia turned the square motherboard in her hand and blew it. This is probably the most sophisticated man-made thing the girl has ever seen. The green substrate, the silver circuit, the densely packed resistors and capacitors, the large and small interfaces, and the dazzlingly complex structure. , Banxia is very careful to dust off, this motherboard has no fan, and a large black heat sink stands in the center of the board.

  It will be the core of the image transmission link.

  It is responsible for converting the image data collected by the camera into an audio signal that can be transmitted by an amateur radio station——

  "Wait, wait, what did you say?" Bai Yang asked, "audio signal? Sound?"

   "Yes, is there anything wrong with Xiao Yang?" Wang Ning put the motherboard on the coffee table and looked up.

   "Convert... into sound?" Bai Yang couldn't believe it.

   "Yes, you heard that right. It just converts the image data into audio signals, and transcodes the photos that your eyes can see into the ‘zizizi’ sound that your ears can hear." Bai Zhen nodded.

"Any data can be converted into sound signals." Wang Ning said, "This is the simplest transmission method. Like electromagnetic waves, sound waves are waves. As long as they are waves, they can be modulated. You usually use voice communication instead of the radio microphone. And an amplifier? If you modulate your voice, it can also carry image information."

   "This... oral transmission picture?" Bai Yang was stunned.

"It can be said that if your tongue and vocal cords are strong enough, you can use your mouth to send out accurate and modulated sound waves to the radio-it sounds a bit like the snake-like voice in "Harry Potter", and the radio side People who have a recorder can record the sound, input it into the computer and transcode it, and then it can be restored to a picture." Wang Ning nodded, "This is why we need a motherboard, because the motherboard usually comes with a sound card."

  "What is information? Information is essentially order and law. Anything as long as you can change its law, it can carry information." Wang Ning continued, "For example, I beat your dad."

   "Go away." Old Bai said.

   "I regularly hit your dad's jaw with my fist, using binary." Wang Ning said, "I can even play an XP system."

   "Then my dad's mandible needs to be replaced with a titanium alloy." Bai Yang said.

  "Sound is the same. Sound waves can be modulated, and it can carry any information." Wang Ning said, "This is currently the simplest and most suitable transmission method for turning two to five."

  "This is the so-called AFSK." Bai Zhen said.

  The two old men brought in a large number of motherboards and cameras, and piled them in the living room. The number was so irritating that Mom said that opening the door was like entering some second-hand electronics market.

  Under the guidance of Wang Ning and Bai Zhen, Pinellia can save anything from the e-waste on the Pearl River Road.

  She sat cross-legged on the floor of the living room, with her back leaning on the sofa, and she said, "Mom and Dad, you said this thing... how did it make it? It’s incredible."

  In Banxia’s imagination, this thing was welded one by one by hand holding tweezers and holding small parts one by one. However, some components on the motherboard are so small that she can’t see them clearly. How to solder them?

  She suddenly picked up her slippers.

  Hold your breath, stay silent for a moment, and then shoot like wind and lightning fast!

The slippers flew out and slammed on the cabinet. For many years, Pinellia had already practiced the ability to distinguish positions by listening to sounds. She saw six directions, listened to all directions, and was more sensitive to the sounds of mice than cats. There was rat movement in the room, and she slammed a slipper over it in a thunderous manner.

   But this time there was no “squeaking” of mice running away. Instead, the debris piled up on the cabinet fell over.

   Banxia had to get up to clean up.

  This is the debris she brought out when she was looking for an English-Chinese dictionary some time ago. At that time, she had not had time to clean it, and it was piled up on the TV cabinet. It was just hit by slippers and it all collapsed.

There are pens and papers, coins, empty boxes, pills for which I don’t know what to do, and the big book "Journey to the West". Banxia puts them all back in the drawer. She is actually a messy person. When people live, they can take things and put them anywhere.

  The girl picked up "Journey to the West" from the ground. It was a huge book. She hardly read it because she couldn't understand it.

  I heard the teacher tell the story of a bald man who took three monsters to Xitian to learn the scriptures.

  Banxia flipped it casually, glanced at the page number, and glanced at the header.

   "San Zang does not forget the original...Four Saints try Zen Mind..."

   Banxia read it.

"The three women turned into the screen and left a pair of silk lanterns. The woman said: Four elders, are you willing to pay attention to that girl who is worthy of me? Wu Jingdao: We have discussed it, and we are under the surname Zhu Zhaozhui. ."

  Turned two more pages and read it casually.

"The woman uncovered her hijab with him and said: Son-in-law, it's not that my daughter is sluggish. They are all modest and refuse to recruit you. Bajie said: Mother, if they refuse to recruit me, you recruit me! That woman Humanity: Good son-in-law! This is not big or small, even mother-in-law!"

can not read.

  I can’t understand at all.

  Can pigs have mother-in-laws?

In this era, books have lost the meaning of existence. The teacher once had many books in his collection, but in the end they were all burned, along with her materials and notes. Banxia still remembers the teacher stupidly throwing them into the brazier and burning them. , Sitting without moving for an afternoon, there may not be many books left in Nanjing. A library as big as Nantu has been evacuated. Of course, people emptied the library not for reading, but for reading. In order to keep warm, there was a year of cold winter in Banxia's memory. The teacher chopped all the wooden furniture into firewood for heating.

  It was the last time it snowed in Nanjing.

"That night the officials dispersed and the demon entered the Yin'an Temple. Eighteen Gong'e Cai girls were selected, playing, singing and dancing, and persuading the demon to drink and have fun. The monster sat on the table alone, and all those who were lined up on the left and right were beautiful and charming. . You see that he is useful, drinking until the second shift, the drunk will come up, can’t help but Hu Wei.” Banxia chanted aloud while pacing in the living room, “jumped up, laughed, and revealed the truth. With a fierce heart, stretched out the dustpan and big hands, grabbed a woman playing the pipa, and took a bite of her head. The seventeen Gong'e was scared to fuck..."

  She was taken aback.

  She suddenly realized that she had read it wrong.

  Fucking is not the original text of "Journey to the West", but the characters written on paper, the characters written in black gel pen, messy and scribbled, and inserted diagonally between the lines of the neatly printed Song Chinese original text.

"my God."

   Banxia said softly.

  This is the teacher's word.

  She stayed for a while, then reacted, and quickly turned the page back frantically. With a short glance, she saw a mess of graffiti, formulas, numbers, English and Chinese characters.

  1200 kilometers.

big eyes.

  25473000.

   Observation.

  Entropy.

  Galaxy.

"Oh my God."

   Pinellia murmured.

  This is not "Journey to the West", but a draft of the teacher.
