Magicraft Meister Part 4

Since there was still some time before the mission was to be launched, everyone was to make their own preparations.

Jin D. decides to build a brainwave scanner as he had declared.

<, but in his own ship .

He said that he can make a small one, since he has a lot of materials and equipment here.

In reality, Jin in Horai Island makes them and sends them to through the warp gate.

"Hmmm... ...... brain scanning and brain wave measurement... ......"

"Brother Jin, can you help me?"

Oh, Elsa. Good place.

Hmm, the old man told me.

I see. Thank you, my old man.

<

Elsa is the world's greatest healer.

If you want to make a magical tool to measure brain response, you can't find a better assistant than her.

"Well, one measures the activity of the . The other measures the spectrum of brain waves."

"N...... got it. <

"I guess so. ...... I could imagine that part of it."

"How accurate can you get with a non-contact device?"

"Yes. That's going to be difficult.

As he discussed the idea with Elsa, Jin's ideas were being developed one after another.

"Chel told me the basic structure. I'd like to use that as a basis.

"I see. ......"

Erza tilted her head and thought for a moment. Jin also thinks about it in his own way.

After a minute or so, Elsa opened her mouth.

"Non-contact is technically possible. But it is difficult to miniaturize it.

"...... seems to be the case."

The technology to construct a magic circle at an arbitrary location and manifest magic has been completed to a certain extent.

However, it is difficult to miniaturize it because of the complex scanning and coordinate fixation required.

"It would be much better if we could limit the effective distance to 10 meters."

"Oh, sure."

Jin estimated that if the effective distance was 100 meters, a desk-sized device would not be sufficient, but a 10-meter device would be about the size of a briefcase.

"Or even smaller at 5 meters."

It was thought that it could probably be made smaller inversely proportional to the square or cube of the distance.

"In terms of practical distance, ......5 meters might be enough."

The advantages of miniaturization are rather large, Elsa said.

"Good. Let's make one with an effective range of 10 meters first, and then one with an effective range of 5 meters.

"That might be a good idea.

This method, however, can only be used with Jin's production speed.

I've got it.

"Okay, it's done.

In about 30 minutes, Jin has built an object with an effective distance of 10 meters.

It was still large, about the size of a from the old days.

The monitor displays the subject's brain waves.

"That's my brother Jin!

I tried to make it as small as possible.

It's portable, so it's practical.

"Even if we improve on this and make it smaller, it may not be half the size for ......10 meters."

A laptop computer would be like a notebook, Jin said.

"Still, it's amazing."

"Well, I'll try to make one with an effective range of five meters first."

So, the next thing Jin made was a rather large magic tool about the size of a tablet.

"This is the five-meter class.

"Hmm, it's practical enough."

At this point, the old man expressed his opinion.

"I see.

It is great to be able to measure even those who are outside the effective range of 5 meters.

"Okay, let's make one with an effective distance of 5 meters, plus extra for the number of people."

Once made, the procedure is manual, so the time required to build the machine is much shorter.

With the help of the <>, 12 <> with an effective range of 5 meters each were completed.

One was sent to Horai Island, one to as a spare, and 10 were sent to . And we will deliver 10 units to .

* * * *

Jin D came out of the , and with a look that said, "I have made it inside", he took 10 units of 5 meter class and 1 unit of 10 meter class. He delivered 10 units of 5-meter class and 1 unit of 10-meter class.

"Oh, wow!　That's just like Jin-dono."

Tomax Bartmann was again astonished at the ability to create such a machine after only about an hour and a half of work.

"Where is Chel?"

"She is touring the inside of <> with Mister Hearn.

Jin was relieved to hear that Makina III and Rey were also accompanying them.

"So, how are we going to use it? ......"

At first, he explained to Tomax Bartmann how to use the device.

It is easy to use.

After the device is activated and the OK message appears on the screen, point the sensor part toward the subject and press the <> switch.

Then the subject's head appears on the screen and the measurement begins.

The test is completed in about five seconds. The short time required to complete the test is another of Jin's innovations.

You are sure there is no harm to the human body?

Of course.

Then, I would like to try it. I'd like to try it out. ...... Fierce, are you ready?"

Tomax Bartmann called Fiona Fias, secretary to the chief administrator.

"Yes, sir."

"You've heard about me, haven't you?　Can I take your brain waves?"

"There is no danger at all. It's just a measuring machine.

Jin D. added, "It is a non-contact brain wave measurement, we are not working on anything.

"Yes, if that's what you mean.

With her permission, Tomax Baartman turned on the Brain Detector for Fiona Fierce.

"How do you feel?

"I don't feel anything."

Five seconds later, an EEG image appeared on the monitor screen.

"This is a little different from the EEG images used in medicine.

Jin explained how to see the image.

The horizontal axis is not time but frequency.

"Oh, I see."

"Think of the vertical axis as level ...... strength."

"Mm-hmm."

It updates every five seconds.

I see.

So, Mr. Fifi's brainwaves are average.

"Um, Mr. Fifi, please don't do that. ......"

After such an exchange, Jin D. instructed the office staff how to use the Brain Detector with the help of the other staff members.
