returned to the club room.
Hyejeong was studying hard for her major, and Changsu and Minseok were nowhere to be seen.
“Well, I did say it out loud. Now how do I remodel this?”
“Yes? What is it?”
As I muttered to myself, Hyejeong reacted.
“Oh, I went to Hyeonseong yesterday and they said they would participate in hybrid engine technology development.”
“Eh? Really? So? How did it go?”
Hyejeong asked if she was interested.
“However, Hyeonseong is still cautious.”
“So? Is that the end?”
“No, that’s why I said I’m modifying the free vector gear. So that it can handle high power and high rotation.”
“Yeah, I don’t know about that.”
“Yeah, anyway, so I said that if the conversion is successful, I’ll let them participate.”
“Oh? Seriously? So if you just modify that, you can participate and make that good engine? Then you can destroy a toyo car?”
Am I mistaken for something that feels like an excited tone of voice?
“…… I don’t know yet, I need to do a little research. I can’t guarantee what to do with the modified Freevector Gear right now.”
I made a loud noise, but um… … . Is it possible?
The geometrical pre-vector gears would have misaligned saw blades even at slightly higher RPMs. I had to find a way to improve it.
“Brother! Is there anything I can do to help you? Just ask me to do anything!”
This time he said it in an excited voice.
“Why is Hyejeong’s tension so good?”
“It’s about destroying Japan.”
“……That’s right, did I mention that there is such a thing as bad feelings the other day? Is that because of what I generally think of as national sentiment?”
“Uh, um… not common.”
“then?”
“I want to know how to bring this story out.”
“Why? If you don’t want to do it, you don’t have to.”
“No. I think you can do it. It’s about my grandmother.”
“Grandma? Come to think of it, did you say that the camera was a keepsake of your grandmother?”
“yes…….”
Granny, what was the story?
“My grandmother… was a comfort woman victim during the Japanese occupation.”
Hyejeong had difficulty speaking out.
“……. Comfort Women.”
During World War II, to satisfy the Japanese military’s s*xual desire… … . A term used to describe women who have been subjected to coercive and gang rape.
I just heard that, and my heart was full.
“When my grandmother was young, she was a journalist. She wanted to report Japan’s viciousness and ignorance to foreign countries.”
“huh.”
“Grandma approached cautiously, but how did the Japanese military know about it… and kidnapped her?”
Clearly, Japan filled comfort women in various ways.
Kidnapping is probably one of them.
“If you don’t tell me after that, you’ll know, right?”
“huh…….”
“That’s how Japan was defeated, and Grandma became free. However, she never forgot the wounds she received then until she died.”
“……Sorry, I asked something stupid.”
“No. Anyway, even after she became free, she continued to dig up information about Japan. You have this camera, right?”
Hyejeong showed the digital camera she was holding and said.
“huh.”
“It contains all the pictures my grandmother took while she was alive.”
“Can I take a look?”
“Yes. I don’t know if I’m shocked instead.”
I looked at the pictures on that digital camera.
It contained all the atrocities of Japan.
Maruta, forced labor, forced conscription, comfort women, etc.
“…… Ha, bastards.”
These were pictures that I couldn’t bear to look at with my eyes open.
“I can’t help but hate Japan.”
“Hyejeong, let’s do this.”
“Which one?”
“I’m going to make an engine that’s better than a road car no matter what. And at the expo next year, we’ll show that our technology is even greater.”
“Yes! I like it! I really like it!”
Hyejeong said with a genuinely happy expression.
“And… when all the attention of the crowd is on.”
“When you’re focused?”
“Let’s make these pictures public.”
“……? Yes? What?”
Tokyo Automobile Expo to be held next year. It is not a simple official stone statue.
It is attended by many world-renowned engineers, businessmen and politicians. If, in such a situation, the atrocities of the Japanese army were reported.
I know the impact will be huge.
“It’s about making it public while everyone pays attention.”
“No, do you know what that means?”
“Yeah. Everyone who participated there will curse at me. It’s because I don’t fit in.”
“You know?”
“Even if they curse, they will know for sure. What kind of atrocities did Japan commit in the past?”
“……That’s right. But, don’t you think about it?”
“No, I’m doing it.”
“Do you know how big the wavelength will be? First of all, everyone there will look down on Cheol-woo oppa. And Japan will completely turn against them. Hyeon-seong, who worked there, will be in an awkward position.”
“I know. People outside Korea and Japan will look at you badly for making a presentation that does not fit the nature of the presentation. Japan will of course become an enemy. Hyeonseong’s position will also be embarrassing.”
I know very well how big a ripple can be if you throw it away without thinking.
before… … . I learned enough from the Ditisa hacking incident.
“But why? Why?”
“Why, if you did something wrong, you should be punished appropriately, and you should give us enough compensation, but there isn’t? You don’t even admit it.”
“That’s it, but…”
“Then what do we do? Keep telling them that we suffered this kind of damage and they don’t do anything or even apologize.”
“Even if that’s the case, what benefit does Cheol-woo oppa have?”
“doesn’t exist.”
“… Then why? Why???”
“It’s just that it’s cool.”
Hyejeong was silent for a while, but only opened her mouth a few minutes later.
“Hogu.”
“Well, think what you like.”

A few days later, I started researching Free Vector Gear in earnest.
‘Oh, really, how do you make this? Should I use something other than steel?”
The free vector gear was made with a lot of short geometric saw blades.
Since the saw blade was short, of course it was inevitable to wear out quickly, and it could not withstand high power and high rotation.
Generally, there were two methods.
One is to make it from a material that is less prone to wear. In other words, making free vector gears with high-strength materials.
If you make a free vector gear with diamonds used in the industry, you will be able to handle high power and high rotation.
However, if there were a few minor problems, it was that although it was for industrial use, it was extremely expensive compared to steel, and it was difficult to process due to its high strength.
In particular, if you want to make industrial diamonds the raw material of free vector gears, which must be made geometrically and elaborately, the processing technology will not be able to go now.
Even if you do, the unit price will be exorbitantly high.
‘Well, that doesn’t mean I can’t make the saw blade longer.’
If the wear is good, you can set the saw blade higher so that it continues to work through the wear.
However, this method also has a minor problem.
A free vector gear is a gear that can move freely in up and down, left and right, forward and backward directions. If you set the blade higher, you will have to give up at least one of the 3 axes.
Then it will no longer be a free vector gear.
“Ha, that’s difficult…”
“what?”
The window sill next to him asked.
“Free vector gear. I need to modify it, but I can’t think of a way.”
“Eh? Is there anything you can’t do?”
“No! I’m a human too, just because I thought I wasn’t made right away.”
“Really? It’s kind of human.”
“…… No, how the hell were you looking at me?”
“monster.”
“…”
“What, so it’s not going well?”
“huh.”
“Hmm, can I give you any advice? Well, when ideas don’t come to mind, you need to change your thinking.”
“A change of mind?”
“Uh, inspiration doesn’t come to mind just by thinking about it. Sometimes, even if you go for a walk or play, something comes to mind.”
“It should be.”
“Yes, and if you keep holding on to something you can’t see the answer to, mental illness will come. Be careful.”
“okay.”
“Well, that’s all the advice I can give. What do I know about that field. Anyway, now that I think about it, it’s really great, because I’m making mechanical devices even though I’m a computer science major.”
“ha ha ha…….”
“It’s really done. It’s done. Anyway, I’m going because I have classes. You also go to classes sometimes.”
Ah, class.
I’ve been busy lately, so I’ve been absent too often.
Some liberal arts courses were already short of attendance, and there were many courses that were in between.
“Okay, then let’s go to class to freshen up.”
“Crazy man, of course you have to go to class.”
“……Then let’s go together, aren’t we in the same class?”
“okay.”
Changsu and I went to the lecture room where the class was held.
This class was an embedded system, an advanced course on digital logic circuits taught by Professor Mansoo Choi.
When I entered the class, there were many students who hadn’t seen me, and there were many who looked at me with curious eyes.
Ignoring their gaze and continuing to think about remodeling the Free Vector Gear, the professor came in before I knew it.
“Oh, who is this? Isn’t it Lee Cheol-woo, a very, wonderful student?”
As soon as the professor saw me, he pretended to know me.
“hahahaha, hello. Professor. I didn’t attend often, did I?”
“hahahahaha, he’s one of the people who shines in our school. How big is his attendance? Don’t worry about grades, do what you want to do!”
The professor said he was proud of me and gave me an A+ for the previous semester’s digital logic circuit course.
“Ha ha ha, thank you.”
When I said that, all the students around me looked at me.
“Okay then, let’s proceed with the embedded system class. What is an embedded system…”
The professor started the class right away.
Embedded systems, I’ve been doing every time. The act of putting a program into an Atmega 128 and running electronic devices.
It was the first thing I learned when I was making House Alerts, and now I am making it easily.

“Professor! I have a question!”
In the midst of class, someone raised their hand and asked a question.
“Oh, isn’t that a good student. So don’t you know what?”
“If it’s an embedded system, is Arduino an embedded system too?”
Arduino was a system that has become a hot issue these days.
It is a product that is packaged so that anyone can easily make hardware if they learn a little. Of course, I don’t like it very much.
It has unnecessary features, so it takes up space unnecessarily, and the price is quite expensive.
just make it
“Arduino, you can definitely call it an embedded system. By the way!”
The professor had a very bad expression.
“This, there is no innovation in Arduino, so I just brought the old one and made it convenient? You can only use it for testing or learning. You can’t design a circuit there, so what kind of trick is this?”
Um, doesn’t it matter?
Even so, it is enough to approach users in a friendly way and sell a lot.
‘No, wait… … . Bring old things as they are and make them convenient?’
There was something that caught my eye among the professor’s words.
‘Didn’t I think so too?’
I was just thinking about remodeling and revising the free vector gear. how to make it convenient
But if you think about it, you don’t have to.
‘Leave the existing free vector gear for low power and low rotation… … . It’s about redesigning the free vector gear for high power and high rotation.’
I had a sudden thought.
Why did you think that the existing one should be improved?
The free vector gear that I am trying to make now has low power and low rotation. It just needs to endure high power and high rotation.
Even if you give up a bit on low power, low revs. It is definitely making a new one that can handle high power and high rotation.
‘Selection and concentration.’
We need to leave the existing free vector gear as it is, and design a new gear that can handle high power and high rotation.
Let’s change that mindset.
‘If I made two T-shapes overlapping, would I be able to handle high power and high rotation while also being able to freely adjust the direction?’
Ideas spring up.
“Professor, I’m sorry. I’ll have to go first.”
I packed my things in the middle of class.
“He’s gone crazy again. He’s a very good student.”
