Start sweeping the universe by rubbing the CPU with your hands

Universal boards, connecting wires, welding guns, diodes, transistors, resistors...

A lot of tools, a lot of ingredients. After adding everything to the shopping cart and paying, more than 7,000 yuan disappeared in an instant, and Han Yang's savings instantly dropped to less than 6,000 yuan.

After another three or four days of self-study, the express package was almost ready. This morning, Han Yang simply washed up, then rode a battery car, put on a dagger, and left the house.

In today's world, even in broad daylight, Han Yang would not dare to go out without a dagger.

A few hundred meters away is a small food stall with a shed and several dining tables and chairs set out in the open air. Many people are already sitting on it.

Han Yang sat down and shouted skillfully: Aunt Wang, big bowl of noodles, with... no eggs!

After thinking about it, Han Yang chose not to add eggs. An egg costs two yuan. I spent so much money on materials, and I didn’t know when I would be able to make it, so I had to save money.

Xiaoyang is here, sit down first, you'll be ready soon!

The big bowl of noodles was brought up, and Han Yang unexpectedly found that there was more noodles in his bowl than before, and there was a layer of oil floating on it.

Xiaoyang, eat more. If you don't have enough, add more.

Han Yang felt a warmth surge in his heart: Thank you, Aunt Wang.

After eating, Han Yang took out his mobile phone and scanned six yuan - the price of a large bowl of noodles was five yuan.

You kid, why are you giving me an extra dollar? Take it back and take it back. If you do this, I won't let you come to my aunt's place to eat noodles.

When Han Yang was about to leave, Aunt Wang took out a piece of cash worth one yuan, chased after him and stuffed it into Han Yang's pocket. Han Yang couldn't refuse and had no choice but to accept.

Thank you Aunt Wang.

Kid, go ahead, be careful on the road.

Han Yang got on the bike and continued walking forward. When passing by Butcher Shen's meat stall, I felt like Butcher Shen glanced at me, and the sound of chopping meat seemed to be louder.

After arriving at the express delivery station and confirming his identity, Han Yang finally got the big boxes.

In today's era, although it is chaotic, the logistics system is still quite reliable. Perhaps the big guys in the logistics business also know that only when they are reliable enough can the logistics business make more money.

After transporting several boxes home, he unpacked them, and piled up the plastic bags, paper boxes and other small items next to them for sale. Looking at the piles of circuit board capacitors and resistors in front of him, Han Yang took a deep breath. Take a breath.

It's time to actually start making it.

Pick up a multi-purpose board, pick up a diode, align the pins, operate the welding gun with the other hand, and weld the diode with a single click.

After more than three months of busy work, this handmade chip was finally completed.

What appeared in front of Han Yang at this moment was a thing divided into four parts. Each part was stacked five or six stories high. Different levels were connected with flying wires. There were also many flying wires on each board. It is full of densely packed capacitors and resistors, as well as some indicator lights, which looks very messy.

Han Yang took a deep breath and pressed the power switch.

He has entered some code into this CPU in pure binary form. The function of these codes is to make the computing chip control the row of indicator lights to gradually light up and then turn off.

The next moment, the code is executed, but the row of indicators does not turn on and off gradually, but all light up at the same time.

What went wrong?

Han Yang was puzzled and spent five days checking before he discovered that a diode had been soldered backwards.

After fixing it, I tried it again, but it still didn't work. Han Yang had no choice but to continue looking for problems. After repeated trials and investigations, more than two months have passed. This time, after pressing the switch, the next moment, the row of indicator lights finally flashed regularly as Han Yang expected.

The code execution was successful. This also means that I have finally successfully made this computer chip by hand.

The next moment, this large pile of circuit boards disappeared in an instant. It replaced the abacus that had always appeared in my mind before and merged into my brain.

The next moment, Han Yang felt the huge computing power. Some problems that were more complicated in the past and would take a certain amount of time to calculate even if integrated with an abacus can now be solved by me in an instant.

At the same time, he felt that his brain was getting clearer. Some almost forgotten memories from the past also emerged instantly and were clearly visible.

Memory is also better.

According to Han Yang's estimation, the frequency of this chip can reach approximately 20KHZ. It can even be overclocked, up to about 35KHZ.

Han Yang looked at the ordinary home computer in use in front of him.

Its CPU frequency can reach up to 5GHZ. In comparison, the frequency of the chip that I made myself and integrated into my head was only about 150,000 times lower.

The CPU process of this ordinary home computer is 3 nanometers. And Han Yang heard that some large supercomputers have already used 2nm process chips. In addition, the Eta people have more advanced computer technology that breaks through the limits of electronics, which is suspected to be a quantum computer.

Han Yang's self-made chip can barely be considered a 5mm chip if we count the manufacturing process.

As we all know, the smaller the computer chip manufacturing process, the higher the technical level and the stronger the performance.

However, 5mm is 2.5 million times larger than 2nm.

Although the difference between the two is as big as the stones and spaceships in the hands of primitive people, Han Yang is still full of joy for the results at this moment.

So what if the performance is poor? The capabilities brought about by the combination of the human brain and computers are far more than just one plus one.

Han Yang even felt that it would only take him a month at most to digest and absorb all the knowledge he had learned in the previous two years.

This matter must be kept strictly confidential. No one can tell it. If the Eta people find out, I will die without a burial place.

After the joy, Han Yang also realized the seriousness of this matter.

After silently making up his mind, Han Yang began to think about the future path. After a while, he came to a conclusion: We still need to find a way to make some money as soon as possible.

Resisting Eta civilization and liberating all mankind is a huge matter and must be done step by step. In the early stage, you must at least have certain abilities and power.

This is obviously inseparable from money.

And, now that I have determined that I have this ability, of course I have to find ways to continue to enhance this ability in the future. I have to think about developing chips with more powerful performance and more advanced technology. One day in the future, I will even go to scale and use factory assembly lines to develop and produce chips.

This is even more inseparable from money. Not to mention the chip factory, at this stage, the more than 10,000 yuan he won from gambling has been almost spent. At this moment, Han Yang is almost out of money to continue buying diodes, resistors, and multi-purpose boards.

Not to mention continuing to buy ingredients, Han Yang could hardly afford to eat the clear soup noodles at Aunt Wang's rice stall.

It’s a full six months, rent, water and electricity, food, Internet fees, everything is free. In other words, Han Yang was used to saving, so he could only survive until now with that little money.

Han Yang was afraid to go to the gambling stall now even to death. He had to find new ways to make money.
