Chapter 2038: 2038 - - 55-13 Meaning of Study Group

The members of the Jin family decided to hold a meeting to discuss the practical application of the flashing light transmitter without Jin.

The meeting was to begin in earnest after breakfast on the following day, the 19th.

"First, how about we list the points that are difficult to use and think about how we can improve them?

Everyone nodded in agreement with Hannah's suggestion.

"That's a good idea."

"Okay, let's start with the shortcomings. First of all, the communication range is short. If we can't see it, it's useless. The amount of information that can be sent is not enough."

At this point, Licia raised her hand and asked a question.

"Wait a minute, Hannah. What do you mean by the amount of information that can be sent?

"Well, I don't know how to say it...... you see, the way we're doing it now is by changing the number of flashes and the intervals between them, giving meaning to the patterns, and comparing them to the corresponding list, and then sending the information."

A primitive form of Morse code, if you will. Or an extension of hand signals.

"Oh, so that's what it is, okay. Go to ...... and keep going."

"Yeah. ...... Any other shortcomings?"

"Well, ......."

"Oh, let's leave aside the cost and the fact that it's hard to make."

Everyone tilted their heads, but so far no one could think of any drawbacks other than those mentioned by Hannah.

"Well, let's think of a way to eliminate the drawbacks!"

"...... I think the communication distance and visibility will be a set, don't you?"

Bina said.

"Increasing the light intensity is a simple idea, isn't it?"

"Yes, I think your sister is right. But if we do that, the light will be too bright, like a searchlight. ...... Oh, yes. How about using infrared light?"

"Hannah, infrared light is invisible to the human eye.

Saki pointed out, but Hanna looked cool.

"Yes. So, how about we use a magi device like a golem's eye for the light receiving part, and use the information from it to make a visible light lamp flash?

"That could be interesting. That's Hannah-chan."

Reinhard is impressed.

"Oh, if we're going to use the magi device, how about decoding the signal instead of just making the lamps flash?

Milowina, who had been silent until now, spoke up.

"...... that's a good idea!"

"Yes, that's it, that's it!"

Hannah and Bina were the first to agree.

"Oh, this is a very interesting discussion!"

"Onii-chan!

Brother Jin!

Then Jin came back.

"Zion and the others are busy entertaining guests, so I just stayed the night and went home.

Jin said that he had left early because he was busy with guests from abroad.

"So, you're looking into a communications device?"

"Yes, I am. Can you give me your opinion?"

Hannah explained to Jin what had happened so far.

"...... I see, so the flashing communication device has been discontinued."

Jin was a little disappointed.

If they had continued to develop it, they might have developed a communication device like the one Hannah and the others were discussing now.

"I like the idea of using infrared for sure."

Jin agrees with the idea.

"Even if it's a little foggy, infrared is a good idea.

He would have preferred to use radio waves, but he does not know how to send them.

But he does know the principle.

When sparks fly, radio waves are emitted.

In reality, this is disliked as .

When you turn on/off a power switch with mechanical contacts near a computer or audio equipment (especially when it is turned off), you may hear noise, but radio waves are also emitted at that time.

"...... but Onii-chan,<> and <> are communicating with each other by magic wave, right?"

Hannah asked a simple question.

"You can use magic waves, but not radio waves?"

"Well, to be precise, it's not that we can't use them, it's more like we don't use them."

"What do you mean?

"Magic waves are better than radio waves because they are easier to use and there is less risk of interference, but radio waves are ......"

Jin said he wanted to take a more magical approach as much as possible because of the problems he sees in modern Japan, such as competition for frequency bands, malfunctioning of electronic devices with radio waves, and the health ...... hazards.

"If you apply high voltage at high frequency to the transmitter antenna, you can probably get a signal to fly."

With that approach, perhaps AM (Amplitude Amplitude　Modulation But I don't think I can make an electronic circuit for it.

"Yes, that's true. I can't make an electronic circuit either.

Hanna admitted that she could not make an electronic circuit.

Without any reference materials, it seems impossible for even Hanna to make it out of the blue.

Then, Erza came up with an idea.

"Brother Jin, but isn't light a kind of electromagnetic wave?

"...... Ah!"

Jin had an epiphany at those words.

"That's right. If that's the case, we can modify the magic of <> to ......."

The difference between radio waves and light is the wavelength.

The wavelengths longer than far infrared rays are submillimeter waves, millimeter waves, and microwaves.......

These wavelengths are used for radar because they have high linearity and are reflected when they hit an object.

Jin thought that if it could emit far-infrared rays, it could also emit microwaves and ultrashort waves with a little more ingenuity, and began to consider the possibility.

"Hmmm...I think I can ...... rewrite the magic formula (Magi Formula) here and change the parameters of this one."

Jin thought about it, and then he recognized the formula.

"Ah, ......<>."

<

"That one was a magnetic field, this one is an electric field. No wonder they are so similar."

It was too late to notice, Jin reflected.

"I think I can transmit."

Jin thinks that he will leave the modulation to the magic brain. The magic brain will be like a CPU.

The problem is reception.

"It sure sounds difficult. ......"

At this point, Meane, who usually keeps quiet and takes care of everyone's tea and refreshments, speaks up unusually.

"Um, there's one thing I don't understand, may I ask you?"

"Of course. May I ask you something, mother-in-law?

Thank you very much. ......Well, there is already a means of communication called <>, so I was wondering why you don't use it.

It was a very legitimate question as to why they don't use or apply the means of communication called <> for those related to Horai Island, and <> for the general public.

"Ah, so that's what you mean. Well, <> is a magical device that communicates with magic waves. And what I'm thinking of now is a magical tool that communicates by radio waves.

"So you are trying to use different things, ...... magic waves and radio waves.

He seemed to have gotten the point somewhat.

"In addition, what we are discussing now is that it is fun to think about."

"Yes, Mother. We all like to think about these things, discuss them, and give them shape.

Elsa added, and finally Meane seemed to be convinced.
