Returning to the Xuanyi, Lin Xi asked, "Who is in charge of the ship now?" ”

The helmsman Fei Zhushan walked over and said, "Back to the Venerable Master, Fei Tingshan, the helmsman of the department, is now in charge of the whole ship. ”

Lin Xi said: "Now Tu Xicai and they are going to go to the Eagle's Beak Cliff first, and after the materials are excavated, they will form a manpower transportation team to send tens of thousands of catties of materials to the Xuanyi." ”

The helmsman Fei stopped the mountain and said: "Returning to the Venerable Master, I have only now known about these situations, and the hot air balloon needs to move with the Xuanyi Army, so now I have basically given the hot air balloon all the fierce fire oil." ”

Lin Xi said: "Very good, now collect all the boats, we have to clear the nearby waters now, and ensure that we are safe when the supplies are delivered." ”

Fei Zhishan said: "Yes, the Ministry will arrange it." ”

"Wait a minute, we still need to do something, you gather all the left-behind personnel of the Engineering Academy, who will be used as prisoners." Lin Xi instructed, and Mi Sanmei said, "I'll do this." ”

......

After a while, in Lin Xi's cabin, Mi Sanmei came over with a group of masters.

Before he could sit down, the Xuanyi trembled slightly and began to paddle in the direction of the deep sea.

A group of masters looked at each other, and Mi Sanmei said quickly: "Don't think about it, the Xuanyi is now moving towards the deep sea, and we will not return until the eagle's beak rock can start to deliver supplies and supplies." Now I took out my sketchpad and listened to the Master's orders. ”

Lin Xi said: "Masters, I have always respected the people who can create, and the masters have suffered a lot in the past, which is due to the system, not the fault of your skills. ”

Smith Liu Cancan's tears flowed: "Master, with your sentence, you are blind to old decay and death. ”

Lin Xi said: "The good days have just begun, so there is no need to die." ”

Liu Cancan wiped away his tears with his sleeve and said happily: "What I said is, what I said is that the old decay must live well." ”

Lin Xi looked at the master craftsmen around him: "Are you a master jade craftsman in the car?" ”

The master jade craftsman stood up in the car and saluted: "Thank you to the Venerable Master." ”

Lin Xi saw another person: "You are Diao Rumu, a master of lacquerware, who made tung oil wrapping." No need to be polite. ”

Diao Rumu, a master lacquerware, also stood up and saluted: "Exactly." ”

"Qi Liu, the master craftsman who made the voltaic battery stack.

You are a kid of Liu Bajia, and you also make bronze, what is your name? ”

A young man with hair on his mouth that had not yet grown stood up: "Back to the words of the Venerable Master, the boy Liu Ci is good at using engraving, and the old men have bad eyes, so they often teach the boy to do delicate work." ”

Lin Xi asked: "Are there any works?" ”

The young man named Liu Ci hesitated for a moment, and Qi Liu said, "Xiao Ci, the Venerable Master asked, it is the time for you to become famous, what are you waiting for?" ”

Liu Ci hesitated and said, "My father's temperament." ”

Qi Liu kicked Liu Ci: "You fool, your father still can't listen to Song Aoxing, Song Aoxing still can't listen to the master?!" ”

Liu Ci then took out a golden cicada and sat in the three-layer cage, what was even more rare was the golden light, Lin Xi was so strange, but Liu Ci was very good: "The golden light is made of mercury to melt the gold into it, and then gilt." ”

[Note: Gilding is the synthesis of gold and mercury into gold mercury, coated on the surface of copper, and then heated to evaporate the mercury, and the gold is attached to the surface of the vessel. The record of gold mercury was first found in the Eastern Han Dynasty alchemist Wei Boyang's "Zhou Yi Shen Tong Deed". The earliest record of gilding technology was seen in the Liang Dynasty. "Compendium of Materia Medica: Mercury Bars" quoted Tao Hongjing of the Liang Dynasty as saying: Mercury "can digest gold and silver to make mud, and people use plating." This account is about eight centuries later than the appearance of gilded objects. 】

[From the cultural relics such as bell and ding vessels, weapons, cars, coins and seals excavated in the past dynasties, the gilding process began in the Spring and Autumn Period and the Warring States Period, and was skillfully applied in the Han Dynasty. In the Sui and Tang dynasties, the gilding technique was refined, and it was widely used in the decoration of palaces, temples, towers and Buddha statues. The Song Dynasty was even more attained and spread it to Japan. 】

Lin Xi was surprised: "You use mercury directly?" That's very toxic. ”

Liu Ci said: "The artisan family has a cheap life, and when you marry a daughter-in-law and have a baby, it will be complete." ”

Lin Xi said: "No wonder you are skillful, no matter what, in the future, the process of mercury must be less, pay attention to ventilation." ”

Then Lin Xiyou saw a person: "You are a coppersmith's head, called Bian Yichang, right?" ”

Bian Yichang saluted and said: "The saint of labor is concerned, and the old decay is exactly." ”

Lin Xi said: "No need to be polite, you coppersmiths have done a lot of things, and we will have many electrical appliances in the future, all of which need coppersmiths to play to their strengths." ”

The coppersmith made the head Bian Yichang and said: "The sage commanded, and we will do everything." ”

[Note: Song Huizong likes others to call himself a saint, so there is a Song Dynasty, and there are many emperors who call him saints, Lin Xi forbids everyone to call him the emperor, and all people use other words. 】

Lin Xi looked at Mi Sanmei again: "That's all?" ”

Mi Sanmei said: "Not really, there are still pyrotechnics and carpenters, but the carpentry master Duan Yongchun and the pyrotechnic master Yuan Tingfang all followed the advance team, led by Song Yuanzheng, if you need to use it, I can call them." ”

Lin Xi said:

"I think now we first make a charcoal microphone, and a dynamic microphone, which is to speak into the microphone, and then at the other end of the copper wire, we can hear the amplified sound.

So, we need charcoal, and I think maybe we can try to pick out some of the sintered bodies left over from the fire.

But before that, we first need to make a galvanometer, a voltmeter.

We need a new kind of eye to see what we couldn't see before. ”

Mi Sanmei said, "Okay, Venerable Master, I'll go find someone." ”

......

Lin Xi asked, "Do we have a magnet?" ”

Song Qingdao: "There are magnets, but the blocks are not big, only half an inch wide and an inch long, some of the boats are simple Sinan, and we now use a small piece of magnet to float in the water on the grass path." ”

Lin Xi took out another drawing board, first drew a magnet, and then at both ends of the magnet, it extended an inch downward, marked as iron.

Then a small copper frame was drawn, the frame is about half an inch high, about nine minutes wide, the frame is made of cork, and the outside is wrapped with thirty circles of tung oil wrapped in fine copper wire, and then the thin copper wire is at the end of the lead, coiled into an involute spiral, and then the two involute spiral ends are fixed on the wooden base, thinking about it and thinking, Lin Xi is on the fixed base, and uses two pieces of wood, and the middle is glued with tung oil, so that the connection between the wooden blocks is completed by the insulation of tung oil - okay, Lin Xi just wanted the tiny current to be shunted by the moisture or conductivity of the wood, thus destroying its accuracy.

The whole designed current pointer deflector, the pointer is a four-inch long thorn made of hardwood, no more than one-third thick, and it is also bonded to the top of the deflection coil bracket with tung oil, and then Lin Xi draws a counterweight on the other side of the deflection axis of the pointer.

The current deflector is designed to be about five inches high, five inches wide, and four inches thick.

Lin Xi wrote on the drawing paper - magnetic deflection galvanometer.

Lin Xi said: "This place is the coil here, you do three kinds of circles at the same time: 100 circles, 50 circles and 30 circles. Is there a problem, if there is a problem, now say, if there is no problem, just do it. ”

Everyone looked at each other, and Song Qing said, "Who does the Venerable Master want to do?" ”

Lin Xi was keenly aware of the situation, so he asked, "Shouldn't we let the best and fastest do it?" ”

Song Qing said: "Returning to the Venerable Master, your thing is not very difficult, and we here including Bian Yichang, Qi Liu, and Liu Ci can do it. Moreover, if it is done, they will have to take credit, which is also rare in the future. ”

Lin Xi thought about it, and it was inevitable that these generals would compete for merit in the future.

So Lin Xi waved his hand: "Bian Yichang, you can arrange it yourself, but I want to make a very delicate thing next, and I still need people." ”

Bian Yichang then said: "Qi Liujun, then, please bother you to make this magnetic deflection galvanometer." ”

[Note: The title of so-and-so Jun is not an invention of the Japanese, but was passed from the Tang Dynasty envoys.] 】

Qi Liu stood up and saluted: "Thank you, Bian Gong." ”

Then Lin Xi took another drawing board, this time he wanted to design a charcoal microphone.

Lin Xi explained while drawing:

"Charcoal microphone, charcoal is the best, purest, blackest charcoal you choose, or the most brittle and hard charcoal that has the sound of gold and stone, and then crush until it is the average size of half a grain of corn, and sift out the fine powder.

Then use a paper tube four minutes deep and one inch in diameter, and fill it with charcoal powder grains;

The bottom of the paper tube is glued and sealed with a round copper sheet;

On the other side, make a copper circle, one point wide, fill in the inner side wall of the paper tube, and then lead out the copper wire;

Then add a little bit of charcoal powder to the paper tube, and slightly bulge out a little bit;

Then soak the thin bamboo paper with tung oil and glue it to the edge of the microphone.

Then make a copper cage that can hold the charcoal microphone on the cage holder. ”

When Lin Xi said this, his mind simulated the charcoal essence microphone, and he felt that he had neglected something.

What should there be?

By the way, there should be a tension mediation structure, Lin Xi remembered that later generations used screws and screws to mediate tension, but now even if the screws can be made by dogs, it is a challenge to match them with threads.

At this time, Mi Sanmei called Lin Xi softly: "Master? ”

Lin Xi came back to his senses and asked, "If I want to have something at the bottom of this paper tube that can be pushed to finely adjust the pressure of the carbon powder particles inside, what is the strategy?" ”

Bian Yichang said: "You can use a wedge. ”

Lin Xi said: "If you don't have to move after you adjust it, it won't change easily?" ”

Qi Liu said: "The wedge is not appropriate, I think the charcoal essence microphone of the master must be often held and moved." ”

Bian Yichang said: "This is really inappropriate, you can add beans." ”

Lin Xi said: "Fine adjustment, fine adjustment. ”

Bian Yichang said: "In that case, there is also something wrong. You can use plug blocks or plug plates"

Lin Xi asked, "What plug block?" ”

Bian Yichang said: "If you choose refined copper or steel, make long strips, grind them with oil stones, and finally polish them with fur, and the two plugs can be fitted together by themselves." It's just that it's easy to stuff it in, but it's not easy to take it out. ”

[Note: Modern feeler gauge, also known as measuring microsheet or thickness gauge, is one of the measuring instruments used to test the gap, the cross-section is a right-angled triangle, and there is a scale on the hypotenuse, and the use of acute angle is directly the short side of the feeler gauge, also known as the measuring micropiece or thickness gauge, is one of the measuring instruments used to test the gap, the cross-section is a right-angled triangle, and there is a scale on the hypotenuse, and the length of the short side is directly expressed on the hypotenuse by using the acute angle of the positive edge, so that the size of the seam can be directly read.

Bian Yichang's plug piece actually contains another meaning, because the plug piece is very thin and flat, so the two plug pieces are superimposed, and they will stick together, because in the case of a very flat situation, van der Waals force and atmospheric pressure will be easy for them to fit together.

Bian Yichang is actually showing their processing skills here in a subtle way.

But unfortunately, such a thing needs a long handle, so it is still not suitable for charcoal transmitters. 】

At this time, Liu Ci said, "Venerable Master, I don't know if my understanding is correct, but if you need to maintain tension, we can make a leaf spring here."

Lin Xi's eyes lit up, and he felt that this was not unacceptable.

But then Liu Ci saw Lin Xi's intention and dissatisfaction, and then said: "If it must be able to be adjusted again, we can also make a runner at the wire plate spring, and the runner can be divided into three to six steps thickness." ”

Lin Xi probably understood Liu Ci's train of thought, but he couldn't be sure that Liu Ci really knew this.

So Lin Xi handed a drawing board to Liu Ci.

Liu Ci used scattered perspective painting to draw the structure.

[Note: Scattered perspective, when the painter paints, the objective objects are correctly represented on the plane, so that they have a sense of three-dimensional and a sense of space near and far, this method is called perspective. Because the perspective phenomenon is near and far small, it is also called the "far and near method". Western paintings generally use "focal perspective", which is like a photograph, the observer is fixed on a foothold, and the objects that can be taken into the lens are taken down faithfully, because of the limitation of space, things outside the field of vision cannot be ingested.

The perspective method of Chinese painting is different, the painter's observation point is not fixed in one place, nor is it limited by the fixed field of view, but according to the need, he moves the foothold to observe, everything seen on different footholds. can be organized into your own picture. This perspective method is called "scattered perspective", also known as "moving viewpoint".

The ability of Chinese landscape painting to express the vast realm of "thousands of miles away" is the result of the use of this unique perspective method. Therefore, only by adopting the principle of "scattered perspective" in Chinese painting can artists create long scrolls of tens or more than 100 meters (such as the picture of the river during the Qingming Dynasty), which cannot be achieved by using the "focal perspective method" in Western painting. 】

Lin Xi nodded and said to Song Qing, "Give him a credit"

Then Lin Xi continued to paint: "Make another base, so that you can put it on the table, and make two copper pillars, so that the tung oil winding copper wire can be connected."

In addition, make a button below, press the button while talking, the power will be turned on, release the hand, and the power will stop!

Let's start with ten. ”

Lin Xi wrote on this kind of drawing - charcoal essence microphone.

Lin Xi explained the second picture clearly, and suddenly felt very tired and tired, but with a sense of accomplishment.

Lin Xi walked out of the cabin, moved his body, and then climbed the watchtower, and Fei Zhishan also followed Lin Xi to the watchtower.

Lin Xi took the binoculars and looked around, and asked Fei Zhushan: "Why do I think there are more fireworks than in the morning?" ”

Fei Zhishan smiled: "I guess it is true that the generals of the Song and Yuan armies have problems, and now if they want to attack us, they must first kill the surrounding soldiers." Otherwise, it is not clear how they themselves died. ”

Lin Xi asked, "How much free time do we have left?" ”

Fei Zhishan said: "It's hard to say, the plan just now, isn't it to wait until the night for us to deliver supplies?" ”

Lin Xi felt that he couldn't ask any results, so he returned to the front cabin again.

Back in the cabin, the chef had already served lunch.

Lin Xi was eating lunch and drawing things, and after a while, he put down his rice bowl and drew a picture.

After another quarter of an hour of painting, Lin Xi finished painting, and everyone looked at what Lin Xi had painted, completely unaware of what it was.

It turned out that Lin Xi changed the round edge of the horn horn into a square cone, which was easier to do, and there was also a smaller horn.

Lin Xi took the small speaker and said first:

"This is a small dynamic microphone, because we only have straight square magnets at the moment, so the coil used for vibrating here is also square.

The coil of the square is eight minutes long. There are three kinds of coils, one thousand turns, one two thousand turns, and one three thousand turns.

The coil lead wire is fixed on the bracket after the horn is cut and bonded with round bamboo, and the other end of the coil is glued in the middle of the vibrating paper cone, and the round edge of the paper cone is glued to the edge of the round bamboo tube.

After you finish it, you use a copper wire mesh to seal the surface of the cylindrical paper basin, and the bamboo tube is three to four inches in diameter.

This kind of first make six of them, and make two of each. ”

Lin Xi marked the drawings with a small moving coil horn.

Then, Lin Xi took out another picture, this picture is very strange, it is an obelisk cone more than three feet long, and a bracket, with a diameter of two feet, and inside is a cylinder made of two heavy copper, both two feet long.

Lin Xi said:

"This is a trombone horn for speaking loudly from a distance.

We don't have testing equipment now, we lack experiments, so we can only quickly realize it first.

The base of this horn horn is similar to the base of the small moving coil horn just now, but it has to output dozens of times the energy, so we need to fill the outer ring of the magnet at the base.

Then a copper through hole is used to gather and emit the sound, and then in another cylinder, it is reflected and transmitted to the large cylinder.

If you lack threads, use rivets, and you must make threads in the future.

By the way, experiment before riveting, connect the speaker and battery with a charcoal microphone, use it, and then rivet it. ”

Song Qing, Liu Ci and Bian Yichang all said: "Oh"

Then he was about to retreat out of the cabin, when the master jade master and the lacquer master Diao Rumu in the car asked, "Venerable Master, don't you have any work for us?" ”

Lin Xi was suddenly prompted and said, "Yes, you stay first." ”

So Song Qing, Bian Yichang and Liu Ci hurriedly got out of the cabin and prepared to go to the workshop.

Lin Xi drew three layers of things, the middle was a piece of paper soaked in oil, the front was a copper foil, and the back was also a copper foil, the copper foil was also welded with a lead, the whole thing was a foot high, three inches in diameter, tightly rolled into a large roll, and the outside was sealed with a bamboo cover.

The master jade craftsman asked in the car, "Venerable Master, this thing seems to be made by Master Diao, what is it?" ”

Lin Xi said: "Capacitors, things that can be used to store thunder and lightning, make ten first." ”
