The Great War of Rhodesia

27. Ribbon Microphone & Audion Tube

Ten days later, the construction of the bathroom was completed. Made quite widely dredging cliff walls, complete with enough bathtub for one person soaking and a water heating furnace.

They took clean water from the Central city by installing pipes extending towards the ravine. And do dirty water treatment using plants that are deliberately planted around the tent, before then proceed to the disposal of water in the Southern city.

Not to forget Aksa also makes a sitting closet, sink, and shower for bathing.

It seems that the existence of such bathrooms makes a new standard for the Rhodesodia region. Be the basic benchmark of how the bathroom should be made. And the first to make changes following those standards was the bathroom in Lucia's residence.

Two weeks later Val successfully completed a sample item from Aksa's request called the Audion Tube and Ribbon Microphone.

And to conduct trials while giving a picture to others, then besides the craftsmen, the, Lucia and the military elite were also invited to come to one of Atelir which was functioned as a place to test all the equipment that was first made. Even some of the leaders of the region attended.

It was not far from Aksa and Nata's tent. It is only a 15 minute walk away. But this time Rafa, Luque, and Lily couldn't keep up. Because they were also having a meeting with Ellian, Selene, the people from the Eastern village, and the Yllgarians. Concerning the medicines to be made.

"So you mean this device can capture sound that then sends it back through the air?" couran asked after hearing Aksa's brief explanation of the thing that was now within his grasp.

It looked like a box made of metal, rectangular with small cavities on one side. It has a metal support similar to the handle of a sword at the bottom.

"Don't we need to do enough by shouting for our voices to be sent through the air? Why wear all the tools?" chirps Jean responded.

"Hahaha..cute Jean, funny." Aksa replied with a cynical tone and a contrived laugh.

They stood around a wooden table in the middle of the room that almost looked like a warehouse. Too many people for the seats available.

"Isn't sound something shapeless? How did that device catch him? What's using some kind of vibration?" Couran was trying to guess how the thing worked.

"Dingdong! You gnash. The device, called the Ribbon Microphone, does capture sound using the help of vibration" Aksa replied later. "Yes, more or less," he added, with a hand that looked like it was weighing something.

"Indeed how do I capture vibrations?" knock someone after hearing Aksa's explanation.

"Not just catch. Even with the addition of other tools, sound can be stored like writing and pictures as on paper scrolls and books," aksa said with another explanation instead of answering the question from the person.

"really? Is that some kind of magic instrument made by Marga Briefier?" knock the other one.

"This tool does not use magic at all. So there's no need for soul flow to run it." This time Nata answered.

"really? How does this tool work?" Couran seemed to be impatient to find out.

Immediately Aksa cleared his throat before then starting to speak. "So basically the sound or sounds are vibrations in a medium. Or rather, pressure on the air. Sometimes when strong enough, we can feel physically."

"Oh right, I've seen sounds that can cause ripples on calm water surfaces."

"Yes, I know about it too. But how about capturing something we can't touch and even storing it?"

"Also send it somewhere else like a message. Without shouting," Aksa added before then returning to a short thud to prepare for an explanation.

"The concept is like when the sound vibrates the water surface earlier. All we need to do is copy the shape of the ripples on the surface of the water into another form.

"After that we just rewrite the pattern on the media we want. It can be on vinyl or aluminum plate if we want to record it, or modulate it if we want to emit again the sound to other places," explained Aksa who looks cheerful with a fluffy smile.

"I still don't understand, Aks," Couran said.

"The concept is the same as a telegram. But we just skip the telegram stage because it is not cool," said Aksa trying to explain.

"So this hollow part is made for where we talk. Where the sound waves will vibrate the band, I mean sheets of metal made very thin inside.

"Oh, and also the sheet metal must be bent zig-zag like a mosquito-burning base to be easy to move when exposed to sound waves.

"And because the sheet of metal tape was mounted between magnets that would generate a magnetic field and generate electricity when the metal tape was moving, the electricity generated would follow the pattern of the tape movement, which is the pattern of the sound waves.

"And, wala! Sound waves have been converted into electricity. Yes, although it still has to be added to the voltage amplifier because without the coil, the electricity generated is relatively small." Aksa closed the explanation of both.

Everyone still remained silent looking at Aksa who looked very excited to explain the concept of the tool work.

"We better show it," Nata said, breaking the silence, which was immediately approved by everyone.

"Yes, I think it'll be a lot easier to understand."

"Eyang Bell used to make the concept of this tool also use water in a copper cup. But it's too complicated and lacking precision." Aksa lifted a wooden box with a large funnel attached to the top. It looks like an incandescent light bulb that is ten times larger is attached to the side of the wooden box. There are also some copper wires that connect the wooden box with a small electric generator at the end of the room.

"For the experiment we will use this wired Telephone," said Aksa then like a teacher who is teaching his students.

Then Aksa assisted Nata, stalling the copper cable that connected the wooden box with a tool called the Ribbon Microphone in his grip. And then Aksa walked out of the room.

Everyone followed Aksa with a view. Until then the young man disappeared behind the door.

Then Nata who still lives in the room seemed to press a switch on the side of the box. And a short, disturbing ringing sound was heard coming out of the funnel at the top.

Everyone immediately transferred their attention from Aksa to the metal funnel.

And shortly thereafter a faint sound was heard from the direction of the funnel.

"Mr Watson, come here. I need you." The sound surprised almost the entire room. Unlike Val, although he managed to immediately disguise it.

It was because although it sounded soft, raspy, and barely recognizable, but everyone knew for sure that it was the voice of Aksa speaking from outside.

"For Lurac!" Go spoke involuntarily after hearing it.

"Why can this be done?" Matyas looked out his eyes staring at the metal funnel on top of the wooden box, as if in disbelief.

"It turns out I still have enough age to witness this crazy thing again" said Haldin who then began to laugh with satisfaction.

Being seen Lucia who had tried to put on the face 'not too interested', immediately changed the look of her face to be very curious after hearing the voice.

"Hows it? You heard?" Suddenly Aksa appeared from behind the door.

"Yes, we heard it." Couran replied still with a surprised face. "And who is Mr Watson?" then he asked unconsciously.
