Chapter 575: Finding backup is perfectly normal!
There is a significant difference between a microcontroller and a single-board computer.
In simple terms, a microcontroller is a type of miniature computer system. Strictly speaking, a microcontroller is one that assembles the entire functional system of a computer onto a single printed circuit board. Most commonly, well, the control core of your home printer is a type of microcontroller.
Single-board computers are much more powerful than microcontrollers and have a certain degree of expandability. For example, the central control unit of your car is a single-board computer.
As you can see, single-board computers are, to some extent, more advanced than microcontrollers.
Therefore, with current integrated circuit technology, Jiang Xia's idea of building a single-board computer is pure wishful thinking. Fortunately, he has the option to experiment. If it were those female experts from the Academy of Sciences, they'd probably be crying their eyes out...
Sure enough, the effect was immediate once the requirements were lowered.
Although the displayed data is still barely acceptable, the resistance of the 10mm wide metal wire is as high as 500w/mm, and the signal delay is >10ns/mm, which limits the clock frequency to below 100kHz.
并且，扫描仪罕见的贴心提示：10mW/门的功耗下，2000门芯片功耗20W → 热流密度 100W/cm2（远超硅片散热极限5W/cm2），必然烧毁。
Tsk, bro, 2000 doors?
Maybe in two more years we can reach the limit you mentioned. Right now, I can only say that you gave us the hint too early!
Let's get started, let's get started! Don't overthink it, let's focus on practical matters first.
If this microcontroller is good and can facilitate convenient information transmission, I imagine the big shots in the team would sell everything they own to get a whole bunch of them.
In this way, the "Five-Year Plan for Computer Development" spearheaded by Jiangxia has made a good start. It allows people to make a living while advancing their research, which is a healthy and sustainable development!
Look, our little guy is already showing some of the qualities of a chief designer. Being strong on his own doesn't count; being able to drive the healthy development of an industrial cluster is what makes him worthy of taking photos with the big shots.
Jiang Xia was already imagining what his little courtyard would look like, filled with these photos.
……
Upon exiting the constructed virtual space, Little Hair was somewhat surprised to find that none of his symptoms of dizziness or weakness had appeared. Wow, this is truly rare. Could it be that the author had a change of heart and decided not to torment him anymore?
It doesn't exist, but we still have to make trouble. However, that Tai Sui seems to be quite useful!
"Hey, Lao Wang, this thing seems like it can be kept as a pet, right?"
"(⊙o⊙)...I've never heard of anything so incredible! I've only ever heard of Tai Sui, no one has ever actually seen one!"
As they were discussing, they heard a commotion outside, and then Teacher Si Chen's loud voice came through:
"A mass of flesh with eyes but no stomach, quite similar to Bimbisara, strange in that it is inexhaustible, yet it feeds on people with a bland taste!"
"Hey~~ Grandpa Liang, can you speak properly?"
Hey! You guys ate this?
"I was just about to eat! I gave some to the eldest first!"
"Hey! The Classic of Mountains and Seas mentions that ancient emperors like Yao, Shun, and Yu all lived to be over a hundred years old because they consumed 'Shi Rou' and 'Ju Rou'."
"Nonsense!" came another slightly older voice. "You're spouting things like the Classic of Mountains and Seas that haven't been verified? Aren't you just misleading our young people?"
Jiang Xia pushed aside Old Wang, who was blocking the doorway, and peeked inside.
Well, while the two explosion maniacs were still busy on the side, two more archaeology maniacs came over to Grandma's side.
However, one of these two people likes to record things, while the other likes to "dismantle" them.
The leader, Wu, raised his hand like a sword, gesturing directly at Teacher Sichen's face: "Structural analysis determines chronology, typology arranges sequence, multidisciplinary research explores human history, and protection takes precedence over ethics! You're supposed to be a teacher at Wudaokou Vocational College, so don't spout those legendary things and mislead students!"
"Xiao Dong, be good! And Xiao Qiu, put down what you're holding. Oh, big sister, don't put it in your mouth either! If anything happens to you, I'll be in deep trouble!"
As he spoke, Leader Wu tried to pull Jiang Dong and the others away.
Unexpectedly, Teacher Sichen straightened up, her thin body blocking Jiang Dong completely.
"Hmph! You dogmatic bunch!"
"According to the Compendium of Materia Medica, 'The fleshy plant resembles meat, attaches itself to a large rock, and has both a head and a tail; it is a living thing.' Others even say that this is a superior-grade herb in this classic text!"
As Teacher Sichen spoke, she took a book out of her bag and patted it on Leader Wu's chest.
"Eat! We'll all eat! We'll make that old man drool. When our eldest sister turns 100, we'll have that old rascal come and pay his respects as a junior!"
Hehe, Teacher Si Chen really knows how to talk. Jiang Xia secretly gave him a thumbs up, while also urging Lao Wang to go over to that pile of white stuff in front of Jiang Dong and cut off a little more.
After all, he had personally verified this thing.
Easy to use!
With the tent flap lowered, slightly isolating the two archaeology fanatics from their argument, Jiang Xia prepared to unleash his flying line technique!
This is a delicate job. Although the pins of modern chips are much larger than those of mature products in later generations, you all know Xiao Dai Mao's craftsmanship.
Jiang Xia closed his eyes, then suddenly twisted several copper wires together, tied one end to his hand and the other end to the handle of the cauldron.
He patted the bronze cauldron beside his feet again: "Hey, ancestor, I'll borrow your body one more time!"
The bronze cauldron rang softly.
"Hey, that meatball, was it also delivered by you guys? I guess I'm benefiting from your generosity!"
The large cauldron is as stable as Mount Tai, just as it was thousands of years ago.
To be so extravagant as to use such a heavy-duty device as a grounding point for an anti-static bracelet, our little rascal has unlocked another achievement that you can never reach!
The scent of pine resin rose, and a faint burnt smell began to permeate the small tent.
Looking at the pins that were once again covered by large clumps of solder, Xiao Dai Mao was finally about to break down.
"Damn it, those disassembly bloggers make solder joints look like child's play, the solder just clumps together on its own! Why is it so hard when I try it myself!"
Yes, it is indeed difficult. Who can blame him when this kid only has rosin as a flux option, not to mention the many different kinds of solder paste available in later generations?
The family's resources are still too meager.
However, with the electronics industry still in its early stages of development, who would bother with those kinds of things? Forget about the most commonly used water-based solder paste or lead-free solder paste; even ordinary rosin-based solder paste hadn't appeared yet!
Hehe, don't underestimate this little thing. A soldering powder made of Sn-Ag-Cu alloys is enough to keep Jiangxia on a tech tree for a while.
Pitiful!
The depressed little guy plugged the soldering iron into the base on the table. Oh well, might as well call for help. Admitting his imperfections is what it means to be honest and open!
Looking behind him, he saw Old Wang and "Big Guy" diligently studying the Tai Sui, trying to prove that it was indeed non-toxic.
"Uncle, aren't you quite skilled with your hands? Can you help me..."
Before they could finish speaking, both Old Wang and Big Guy stretched out their fingers and slowly shook them at Jiang Xia.
"Your pointed soldering iron isn't even as thick as our fingers..."
Looking at the "carrots" the two of them were holding up, Jiang Xia then looked at the instructor beside him who was trying hard to memorize the circuit diagram.
"Instructor, didn't you say you repaired large tractors at the grassland tractor factory? You must be quite skilled, right?"
The instructor looked up and silently made a gesture as if he were swinging a sledgehammer.
Well, the current version of the 59 doesn't really have anything sophisticated; using a sledgehammer to repair it is perfectly reasonable...
Or, how about letting the two little girls give it a try?
Jiang Xia suddenly had a thought and remembered his family.
wrong!
Looking for Grandma!
When I was little, I watched my grandma embroider a fan. The front had a white cat, and when you flipped it over, it became a yellow cat. The outlines of the patterns on both sides were exactly the same.
With that kind of sharp eye, dealing with these stitches is a piece of cake!
This is what they call "brothers fighting tigers together, and grandsons nursing their grandchildren on the battlefield!"
"Grandma! Come help me..."
