"Liugong, what did you ask me to see?"

This came to the workshop, Yang Qiao was very curious, here, there is nothing more, but a grinder, however, this grinder has been transformed, it was originally a grinder with manpower, and now it uses an electric motor, but the shotgun has been replaced.

If there was another traverser directly in this workshop at this time, he would definitely not think that this was the Tang Dynasty, but would think that this was the seventy or eighty years of Yang Qiao's previous life!

However, take a closer look, what are those sand shales for, they are naturally used to make grinding wheels, at this time, there are no glued grinding wheels, and naturally there will be no such materials and that kind of materials, however, this sand shale is also different, Yang Qiao arranged for people to find many kinds of sand shale.

This side is a grinder, there is a drilling rig, naturally, this drilling rig also uses electricity, but, look carefully, this appearance is the same as the previous life, but this drill bit is different, it is not a twist drill, but an ordinary steel straight drill.

And over there, a small air hammer was even made, which was also made by Yang Qiao, which was used to quickly make some less important parts, if it was a fine part, it still required craftsmen to hammer it out with a pliers hammer head.

"Lang Jun, look at this."

As he spoke, the Liugong picked up a piece of iron from a pile of iron pieces on the side.

"What's this, you can't make a new grinding wheel?"

"Well, Lang Jun, originally, I wanted to use this iron piece, punch holes on it, and then dip this iron piece in fire, isn't this just rigid, I want to use it as a file, but, Lang Jun, you know what's going on."

This kid is getting more and more mysterious.

I saw that he quickly replaced a grinding wheel and replaced it with this iron plate, and this iron plate was a circle of small holes.

Obviously, the readers who see this are all smart people, and this is obviously the discovery of the principle of the phonograph, which is the thing invented by that little love.

With the replacement of the iron sheet, Liugong closed the gate knife, and the grinder flew up.

Then, he took a piece of iron and rubbed it against the grinding wheel file.

"Dingdingding......"

"Lang Jun, this voice is beautiful, beautiful, you see, can this make something?"

"Something to make, you say, if, store sound!"

"Store the sound, store the sound, this sound, can it be stored?"

"Can't store it, you think, how did this sound come from, you play the piano, and you have to have various styles of strings, and this, don't you just take an iron piece, this has a different sound, okay, you think about it yourself!"

These people are used to relying on Yang Qiao, what is the matter, they all came to Yang Qiao, no, they just found a little color, and they came.

"Also, to give you a reminder, over there, the newly developed hard film, if you use a needle, will it, and this iron sheet, if you put it sideways!"

In order to give him a goal for his research, Yang Qiao had to remind him a little more.

And the so-called hard film is a new product of the old way, a chemical product, this old way, Yang Qiao really didn't expect it, it was really good, so talented, he actually wrapped up the door of chemistry, and even, it attracted a few liars, ah no, it's the same party, ah, no, it's the same kind, always, it's all cheating, eating and drinking, and they all have research on this chemical industry, although it's a primary primary, but, it's always a prototype, no, the first thing to appear, it turned out to be this film, what is it for? Naturally, it is for use as a container, and it is brisk.

However, are they really for the purpose of making containers, in fact, actually, "That, Brother Dao, this is just an accidental discovery, it is this kind of water, this glue, and this kind of thing together, and we inadvertently made a wrong move, this kind of thing appeared, and then, we found that this, to make a container, maybe it will be more cost-effective, cheaper than a glass container, cheaper than a copper container, cheaper than a wood, light and brisk of iron, that's it, hehe, hey, hey, immeasurable Dao Venerable, Dao brother." ”

"Well, yes, you continue to study, whatever, I don't ask you anything, but, what you ask, you must do it well, you know?"

However, I don't know if this film is suitable for making that film, let the engineer study it himself, this, Yang Qiao won't worry about it, originally, this is not an important thing.

"Dao Chief, please."

"Immeasurable Dao Venerable, how can Liugong have the leisure to come here from Lao Dao? Is it still a matter of wires, but we still haven't studied this. ”

It seems that this Liugong has added a lot of trouble to these Taoists, what is the trouble, in fact, it is the trouble that Yang Qiao gave them, that is, the matter of wire rubber, every time, this old Taoist researched a kind of rubber, and it was stopped by Liugong Unqualified, the so-called unqualified, naturally not softness, this, is on the surface, naturally, these old Taoists will be successfully manufactured, but, the anti-penetration ability is not successful, so, it is to stop, stop.

At this time, what kind of wire is used, because there are not many users, so, at this time, the use of enameled wire with yarn wrapped wire, this kind of line, can not be said to be bad, that is, the process is complex, especially under the premise of no automatic machinery, it is more troublesome, but it is good, but it is to contribute to the population of Chang'an, and this, together with textiles and carpets, is the three major industries used by female workers, that is to say, there is no need for Yang Qiao to say anything to those women, those workshop owners who employ workers, in fact, are some families, They will take the initiative to find some reasons to use female workers, not to use male workers, isn't it, male workers are scarce, that is, female workers are starting to be scarce.

For this reason, the transportation industry of Datang has also developed, that is to say, at this time in Datang, there is already a shuttle bus to pick up and drop off employees, which is advanced enough, but this shuttle is worse, a four-wheeled horse-drawn train, and soon, this horse-drawn rail train will also be available.

"Don't worry, Dao Chief, I'm not here to urge you, but to ask you for help, I heard that you have developed a new hard rubber board ......"

The craftsmen under Yang Qiao are becoming more and more accustomed to what is called division of labor and cooperation, no, this Liugong, it didn't take long for him to gather more than a dozen people to study this matter.

"Xiao Li, I heard that when you were winding the coil, you ever heard the vibration sound of the coil?"

"Well, isn't it because of the vibration that I glued the coils together with varnish, what?"

"And you, I heard, you use this wire ......"

This Liugong, is it a bag to inquire about it, who has ever encountered something, as long as he feels that it may be useful, at this time, he has found it.

"Today, I came to you to study this matter, rest assured, after Lang Jun's clear road, originally, you are also idle, idle is also idle, it is better for us to study this problem about sound storage, you don't have any doubts, Lang Jun said, this sound, can be stored, Lang Jun said yes, that is, Lang Jun also gave a clear road, that is, to use the hard rubber plate to store the sound, pick it up with a needle, this is the only inspiration that Lang Jun gave me, and what is my inspiration, is the sound made by this iron piece."

"I heard it, I heard it, Liugong, can you slow down this speed, or, don't use electricity, just turn it by hand, I'll listen to it again, yes, turn it at a more uniform speed."

This is a craftsman who is sensitive to sound, he generally detects whether there are defects in some workpieces, such as an iron workpiece, as long as he knocks on each part at a uniform speed on it, he knows that this workpiece is qualified or not, because there is no flaw detector or anything at this time, so this ear has become an important equipment, not to mention, the workpiece that has been tested by him has very few problems, very few, and he detects that there is a problem, as long as he smashes it open to see, you can see that there is really a hard injury inside, Or maybe there's some air eye or something.

However, this speed has slowed down, and not only he understands it, but others also understand it.

"This is the height of this bulge, in fact, if it is converted, it should be the length."

Soon, someone came up with an understanding.

Therefore, the first thing that was built was not a gramophone, but a music box.

"But, everyone, this is not what I want, so many days, but this thing is not bad, after trimming, it is good to be able to complete a musical work."

That's right, it's this music box, it's not driven by a tight spin, it's cranked by hand, and it also requires speed.

Well, this is considered a toy for the daughter, production, toy production, someone wants to talk about it! In this way, Yang Qiao put some toys and inventions such as jewelry on the shelf.
