Chapter 3 Chip

Multi-purpose board, connecting wire, welding gun, diode, triode, resistor...

A lot of tools, a lot of raw materials. After adding all of them to the shopping cart, as soon as the payment was made, more than 7,000 yuan disappeared in an instant, and Han Yang's savings instantly fell to less than 6,000 yuan.

After another three or four days of self-study, the express packages were almost all here. This morning, Han Yang simply washed up, then rode his electric bike, took a dagger, and left the house.

In this world today, even in broad daylight, Han Yang dared not go out without a dagger.

A few hundred meters away was a small food stall with a shed and several tables and chairs in the open air, on which many people were already sitting.

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

After thinking about it, Han Yang chose not to add eggs. An egg costs two yuan. He spent so much money on buying materials, and he didn't know when he could make it, so he had to use it sparingly.

"Xiaoyang is here, sit down first, it will be ready soon!"

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

"Xiaoyang, eat more, add more if it's not enough."

Han Yang felt warm in his heart: "Thank you, Aunt Wang."

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

"You kid, why did you give me an extra dollar, take it back, take it back, I won't let you come to eat noodles at my aunt's place in the future."

When Han Yang was about to leave, Aunt Wang took out a one-dollar cash note, chased after him and stuffed it into Han Yang's pocket. Han Yang couldn't refuse, so he had to accept it.

"Thank you, Aunt Wang."

"Go ahead, kid, be careful on the road."

Han Yang rode on his bike and continued to move forward. When passing by Shen the Butcher's meat stall, he felt that Shen the Butcher seemed to look at him, and the sound of chopping meat seemed to be a little louder.

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

In this era, although the logistics system is chaotic, it is still quite reliable. Perhaps the big guys in the logistics business also know that only by being reliable enough can the logistics business make more money.

After transporting a few boxes home, unpacking them, carefully piling up the plastic bags, paper shells and the like next to them to sell for money, looking at the pile of circuit boards, capacitors, resistors and other things in front of him, Han Yang took a deep breath.

It's time to really start making.

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

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 chip divided into four parts, each of which was stacked five or six layers high, and the different levels were connected by flying wires. There were also many flying wires on each board, which were full of densely packed capacitors and resistors, as well as some indicator lights, which looked very messy.

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

He had already input some codes into the CPU in a pure binary way. The function of these codes was to make the computing chip manipulate the row of indicator lights to light up and then go out gradually.

The next moment, the code was executed, but the row of indicator lights did not light up and go out gradually, but all lit up at the same time.

"What went wrong?"

Han Yang was puzzled and checked for five days before he found that a diode was soldered upside down.

After repairing it, he tried again, but it still didn't work. Han Yang had to continue looking for the problem. After repeated experiments and repeated inspections, more than two months passed. This time, after pressing the switch, the next moment, the row of indicator lights finally flashed regularly as Han Yang expected.

The code was executed successfully. This also means that this computer chip was finally made by hand.

The next moment, this pile of circuit boards disappeared instantly. It replaced the abacus that always appeared in his mind and merged into his brain.

The next moment, Han Yang felt the huge computing power. Some of the problems that were more complicated in the past, even if they were integrated with an abacus, could be calculated in an instant.

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

His memory was also better.

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

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

Its CPU frequency can reach up to 5GHZ. In comparison, the chip that he made by himself and was integrated into his head has a frequency of only about 150,000th of it.

The CPU process of this ordinary home computer is 3 nanometers. And Han Yang heard that some large supercomputers have already used 2-nanometer process chips. And the Itar people have more advanced computer technology that has broken through the electronic limit, which is suspected to be a quantum computer.

If we have to count the manufacturing process, this chip made by Han Yang can barely be considered 5 mm.

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

And 5 mm is 2.5 million times larger than 2 nanometers.

Although the difference between the two is as big as the stone and spaceship 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 ability brought by the combination of human brain and computer is far more than just one plus one.

Han Yang even feels that all the knowledge he learned in the past two years can be digested and absorbed in one month at most now.

"This matter must be kept strictly confidential. No one can tell. If the Itar people know about it, I will die without a burial place."

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

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

Resisting the Itar civilization and liberating all mankind is too big a matter, and it has to be done step by step. In the early stage, I must at least have a certain ability and power.

This obviously cannot be separated from money.

And, since I have confirmed that I have this ability, I must of course find a way to continue to enhance this ability in the future. I want to think about developing chips with more powerful performance and more advanced technology. One day in the future, I will even scale up and develop and produce chips in the way of factory assembly lines.

This is even more inseparable from money. Not to mention the chip factory, at this stage, the more than 10,000 yuan won from the gambling den 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 materials, Han Yang can't even afford the clear soup noodles at Aunt Wang's food stall.

It took a full six months, rent, water, electricity, food, Internet fees, everything is free. It's because Han Yang is used to saving money that he can last until now.

At the gambling den, Han Yang dare not go there anymore, and he must find a new way to make money.
