    ,

    This afternoon, the girl was still tossing the main board. The main board that had been placed in the humid climate for twenty years was like a petri dish of mold, with brightly colored hairs. At first glance, I thought it was a palette of paints.  Clean them up and put them outside in the sun. Wang Ning said that it is best to find an unopened and unused motherboard. Industrial control or military motherboards are the best, because they use tantalum capacitors, which are not easy to break.

    "For the 3150 industrial control motherboard, find a Celeron 3150 fanless industrial control motherboard. I think it should work." Wang Ning said, "It's easy to find this thing on Zhujiang Road."

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

    "Xp, or win7." Wang Ning replied.

    "Very good." Bai Zhen nodded, "That can call the red police."

    Ban Xia turned the square main board in her hand and blew it. This is probably the most precise man-made object the girl has ever seen. It has a green substrate, silver circuits, dense resistors and capacitors, large and small interfaces, and the structure is so complex that it is dazzling.  , Pinellia brushed off the dust very carefully. This motherboard has no fan, and a large black cooling plate 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 audio signals that can be transmitted by amateur radio stations¡ª¡ª

    "Wait, wait, what are you talking about?" Bai Yang asked, "Audio signal? Sound?"

    "That's right, what's wrong with Xiao Yang?" Wang Ning put the motherboard on the coffee table and looked up.

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

    "Yes, you heard that right, it is to convert the image data into audio signals, and transcode the photos that your eyes can see into the 'Zi Zi Zi Zi' sound that your ears can hear." Bai Zhen nodded.

    "Any data can be converted into a sound signal." Wang Ning said, "This is the simplest transmission method. Like electromagnetic waves, sound waves are also waves. As long as they are waves, they can be modulated. You usually use voice communication to rely on radio microphones.  And amplifiers? If you modulate your voice, it can also carry image information.¡±

    "This the word-of-mouth map?" Bai Yang was stunned.

    "Suffice it to say, if your tongue and vocal chords are strong enough, you can put your mouth into the radio and emit a modulated, accurate sound wave - it will sound a bit like Parseltongue in Harry Potter, and the radio over there  Most people have a tape recorder, record the sound, input it into the computer to transcode, and then it can be restored into a picture." Wang Ning nodded, "This is why we need to use a motherboard, because the motherboard usually comes with a sound card."

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

    "Get out," Lao Bai said.

    "I regularly hit your dad's jaw with my fist quickly, using binary." Wang Ning said, "I can even create a Windows system."

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

    "The sound is the same. Sound waves can be modulated, and it can carry any information." Wang Ning said, "This is also the simplest and most suitable transmission method at present."

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

    The two old men brought a large number of motherboards and cameras and piled them in the living room. The number was so large that my mother was annoyed. My mother said that opening the door seemed to be in some second-hand electronics market.

    Under the guidance of Wang Ning and Bai Zhen, Banxia can collect anything from the electronic waste on Zhujiang Road.

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

    In Ban Xia's imagination, this thing is soldered one by one by hand with tweezers holding small parts, but some components on the main board are so small that she can't see them clearly, how should they be soldered?

    She suddenly picked up the slippers.

    Hold your breath and concentrate, be silent for a moment, and then move like the wind, as fast as lightning!

    The slipper spun and flew out, and slammed on the cabinet with a "slap". Over the years, Banxia has already developed the ability to listen to sounds and distinguish positions. She can see all directions and listen to all directions.  When there was a mouse movement in the room, she smashed it with a slipper with lightning speed.

    However, this time there was no "squeak" sound of mice escaping, but the sundries piled on the cabinet fell down with a "crash".

    Ban Xia had no choice but to get up and clean up.

    ?This is the sundries she brought out when she was looking for an English-Chinese dictionary some time ago. She didn't have time to clean it up, so she piled it up on the phoneOn the video cabinet, just after being hit by a slipper, it all collapsed.

    There are pens and paper, coins, empty boxes, pills that I don¡¯t know what to do with, and the tome "Journey to the West". Ban Xia stuffs them all back into the drawer.  When people live, things can be taken anywhere.

    The girl picked up "Journey to the West" from the ground. It was a big thick volume. She almost didn't turn it over because she couldn't read it.

    I heard from the teacher that it was a story about a bald man who took three apprentices to the West to learn scriptures.

    Ban Xia casually flipped through the page, glanced at the page number, and glanced at the header.

    "Tripitaka never forgets the origin The Four Sages test their Zen mind"

    Pinellia read it.

    "The three women turned into the screen and left a pair of gauze lamps behind. The woman said: Four elders, are you willing to pay attention to who is suitable for my little girl? Wujing said: We have already discussed, and I will recruit that pig surnamed  .¡±

    I turned two more pages and read it casually.

    "The woman uncovered her head with him and said: Son-in-law, it's not that my daughter is obedient, they are all humble and refuse to recruit you. Bajie said: Mother, since they refuse to recruit me, you recruit me! That woman  Humanity: What a good son-in-law! This is no big or small, even the mother-in-law wants it!"

    can't read.

    I can't understand it at all.

    Why do pigs have mothers-in-law?

    In this era, books have lost the meaning of existence. The teacher used to have a lot of books, but they were all burned in the end, together with her materials and notes. Ban Xia still remembers the teacher's expression on throwing them into the brazier and burning them.  Sitting there all afternoon without moving, there may not be many books left in Nanjing City. A library as big as Nantu has been emptied. Of course, people evacuate the library not for reading, but for reading.  In order to keep warm, Ban Xia remembered that there was a year when the winter was so cold that the teacher chopped all the wooden furniture into firewood to keep warm.

    That was the last time it snowed in Nanjing.

    "That night when all the courtiers dispersed, the monster entered the Yin'an Hall. Eighteen court ladies were selected to play and sing and dance, and persuade the monster to drink and have fun. The monster sat alone on the table, and the people lined up on the left and right were all beautiful and charming.  You can see that he is very useful. After drinking until the second watch, the drunk will come up and can't help doing anything." Ban Xia recited aloud, while pacing in the living room, "jumped up, laughed, and found the truth  Sudden murderousness, he stretched out his big dustpan hand, grabbed a woman playing the pipa, and bit her head abruptly. Scared those seventeen maids to go to hell"

    She was taken aback.

    She suddenly realized that she had read it wrong.

    Fuck it, it's not the original text of "Journey to the West", but someone wrote it on the paper, with a black gel pen, messy and scribbled, inserted obliquely between the lines of the neatly printed original Song typeface.

    "my God."

    Ban Xia said softly.

    This is the teacher's word.

    She was stunned for a while, and then she realized that she frantically turned the pages back. In a short glimpse, she saw a mess of graffiti, formulas, numbers, English and Chinese characters.

    1200 kilometers.

    big eyes.

    25473000.

    Observation.

    Entropy.

    Galaxy.

    "Oh My God."

    Ban Xia murmured.

    This is not "Journey to the West", but the teacher's draft.
