Chip

Universal board, connecting wires, soldering gun, diodes, transistors, resistors...

A large pile of tools, a large pile of raw materials. After adding everything to the shopping cart and paying, over seven thousand yuan instantly vanished, and Han Yang's savings plummeted to less than six thousand.

After another three or four days of self-study, the express packages had mostly arrived. This morning, Han Yang simply washed up, then rode his electric bike, taking his dagger with him, and left the house.

In this day and age, even in broad daylight, Han Yang wouldn't dare go out without a dagger.

A few hundred meters away was a small food stall, with a shed covering it and several dining tables and chairs set up outdoors. Quite a few people were already seated there.

Han Yang sat down and skillfully called out, "Aunt Wang, a large bowl of noodles, add... no egg!"

After thinking for a moment, Han Yang decided not to add an egg. An egg cost two yuan. He had spent so much money buying materials, and he didn't know when he would be able to make it, so he had to be frugal.

"Xiao Yang is here, sit down first, it'll be ready soon!"

The large bowl of noodles was brought over, and Han Yang was surprised to find that the noodles in his bowl were more than usual, and there was a layer of oil floating on top.

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

A warmth surged in Han Yang's heart: "Thank you, Aunt Wang."

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

"You child, why give an extra yuan, take it back, take it back, if you do this again I won't let you eat noodles at Auntie's place anymore."

As Han Yang was about to leave, Aunt Wang pulled out a one-yuan bill, chased after him, and stuffed it into Han Yang's pocket. Han Yang couldn't refuse and could only accept it.

"Thank you, Aunt Wang."

"This child, go, go, be careful on the road."

Han Yang got back on his bike and continued forward. When he passed Shen the Butcher's meat stall, he felt as if Shen the Butcher looked at him, and the sound of chopping meat seemed to get louder.

At the express delivery point, after confirming his identity, Han Yang finally got the large boxes.

In this era, although chaotic, the logistics system was still quite reliable. Perhaps the big players in the logistics business also understood that only by being reliable enough could the logistics business make more money.

He transported the boxes home, unpacked them, carefully piled up the plastic bags, cardboard boxes, and other things on the side to sell for money, and looked at the large pile of circuit boards, capacitors, resistors, and other things in front of him. Han Yang took a deep breath.

It was time to truly start making it.

He picked up a universal board, picked up a diode, aligned the pins, and operated the soldering gun with his other hand, gently touching it to solder the diode on.

After being busy for a full three months, this handmade chip was finally completed.

What was presented before Han Yang at this moment was something divided into four parts, each part stacked five or six layers high, with different layers connected by flying wires, and each board also had many flying wires. It was full of densely packed capacitors and resistors, as well as some indicator lights, looking very messy.

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

He had already input some code into this CPU using pure binary. The function of this code was to make this computing chip control that row of indicator lights to gradually light up and then go out.

The next moment, the code executed, but that row of indicator lights did not gradually light up and go out, but all lit up simultaneously.

"Where did something go wrong?"

Han Yang was completely puzzled. He checked for a full five days before realizing that he had soldered one diode backward.

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

The code executed successfully. This also meant that he had finally successfully handmade this computer chip.

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

The next moment, Han Yang felt a massive computing power. Some problems that were previously quite complex, even requiring some time to calculate even with the abacus integrated, he could now calculate in an instant.

At the same time, he felt his brain becoming clearer. Some memories that had almost been forgotten in the past instantly surfaced, clearly visible.

His memory was also better.

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

Han Yang looked at the ordinary home computer he was currently using in front of him.

Its CPU frequency could reach a maximum of 5GHZ. In comparison, the frequency of the chip he had personally made and integrated into his head was only about 1/150,000 of that.

The CPU process of this ordinary home computer was 3 nanometers. And Han Yang had heard that some large supercomputers had already applied 2-nanometer process chips. Also, the Ita had more advanced computer technology that had broken through the electronic limit, suspected to be quantum computers.

If Han Yang's self-made chip had to be calculated in terms of process, it could barely be considered 5 millimeters.

As is well known, the smaller the computer chip process, the higher the technical level and the stronger the performance.

And, 5 millimeters is 2.5 million times 2 nanometers.

Although the difference between the two was as great as the difference between a stone in the hands of a primitive man and a spaceship, Han Yang was still filled with joy at the current result.

So what if the performance was poor? The ability brought about by the combination of the human brain and the computer was far more than just one plus one.

Han Yang even felt that all the knowledge he had learned in the past two years could now be fully digested and absorbed in at most a month.

"This matter must be kept strictly confidential. I can't tell anyone. If the Ita 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 moment, he came to a conclusion: "I still have to find a way to make some money as soon as possible."

Resisting the Ita civilization and liberating all of humanity was too big a task; it had to be done step by step. In the early stages, he had to at least possess a certain level of ability and influence.

This was obviously inseparable from money.

Also, since he had confirmed this ability he possessed, he naturally had to find a way to continue strengthening it in the future. He needed to figure out how to research and develop chips with more powerful performance and more advanced technology. One day in the future, he even wanted to scale up and research and produce chips using a factory assembly line method.

This would require even more money. Not to mention a chip factory, at this stage, the more than ten thousand yuan he won from the gambling den was almost spent. At this moment, Han Yang was almost out of money to even continue buying diodes, resistors, and universal boards.

He was even close to not being able to afford the plain noodles from Aunt Wang's food stall, let alone continue buying materials.

Six full months! Rent, utilities, food, internet fees, what didn't cost money? It was only because Han Yang was used to being frugal that he could make that little bit of money last until now.

He absolutely dared not go back to the gambling den now. He had to find a new way to make money.
