industrial maniac

Chapter 102 Peerless Mechanic Zhang Fei
The repair shop of the physics teacher is at the gate of Huangnigang No. [-] Middle School.

A rammed-earth hut stacked with three black-and-white TVs waiting to be repaired, and a host of old radios.

These days, it's normal for teachers to have side jobs.

Like Wong Nai Kong.

The county budget allocates funds to the township, and the township distributes the salaries to the teachers.

If the county has no money, the township can only issue IOUs, that is, the monthly salary will not be honored, and it will be calculated together at the end of the year.

If you still have no money at the end of the year, wait until the next year.

Teachers can’t get their salaries, and occasionally they are forced to donate money by the competent department, plus a monthly assessment fee is deducted...

In the end, it is necessary to engage in a side job to support yourself.

Lou Nannan's parents raised five cows.

The teacher of Yuhong Class planted seven acres of land.

A physics teacher who runs this repair shop in his spare time.

Fortunately, entering the new century, the salary of teachers has improved slightly.

At least the salaries of the teachers in Huangnigang have surpassed that of Gucheng County.

The physics teacher dug out a pile of drawings, and put many tools into the snakeskin bag.

Everyone came to the toy factory together, and walked into the idle workshop that Xu Fei often used.

Since there is no 'laboratory' module, you have to analyze the finished product and make samples by yourself.

In Daze, Xu Fei spent all his time studying 'analog circuits' except paying attention to overseas news.

While referring to textbooks, make it by hand, and use the basic production line to manufacture the required raw materials or semi-finished products.

include:

Copper wire, tin wire, silver wire, gold wire...

Aluminum cylinder, metal tantalum, polyester plastic material, ceramic film...

Carbonaceous particles, glaze insulating layer, glaze insulating varnish...

Connect these things in series according to their functions, so there are wires, resistors, and capacitors.

Connecting small speakers, the higher the requirements, the more complicated the wiring.

If you add copper clad laminates, copper foils, prepregs, chemical potions made of glass fiber cloth...

Then adjust the line to the 'panel', and there will be a circuit board.

In order to make circuit boards, Xu Fei prepared a bunch of tools.

Hacksaw blade, fine sandpaper, quick-drying paint, small pad pen, small electric drill, knife, carbon paper, rubber water, ballpoint pen, ruler, compasses...

In order to test the performance of the circuit board, a bunch of electrical equipment was purchased.

Fortunately, the computer that comes with the four-level basic production line has the function of 'simulation circuit'.

When designing the circuit, it can help simulate the overall effect, without having to conduct experiments again and again.

At present, with the help of the four-level basic production line, Xu Fei can make a circuit board the size of a 1 yuan coin, with a thickness of 1 mm and a line width of 1 mm. It can control the volume of the sound, switch between five lines, and turn the power on and off.

In addition, a three-layer circuit board of the same size for controlling the turning on and off of the lights was produced.

For example: Arrange 200x200 mini bulbs on a wooden board, through this circuit board, you can generate 'Xu Fei', 'Director', 'TEP', and even switch back and forth manually.

No matter how many fonts and functions, it is temporarily impossible.

Because the more controls, the more complicated the circuit and the bigger the circuit board.

According to the content of the book, the circuit board is called PCB, not an integrated circuit IC, let alone a microcircuit chip.

At present, these things, along with the operating table, are transported to the idle production line.

Xu Fei introduced his masterpieces to everyone one by one.

Lou's father and the teacher of Yuhong class were amazed, "Is it so busy to be the factory manager?"

The physics teacher asked curiously, "Why don't you find a manufacturer to customize? Or, recruit a group of electrical engineers to help your company design the PCB you want, and even develop EDA, design IC, and microcircuits?"

"TEP does not support this project, I plan to do it myself."

"Then you are now basically at the level of...the 30s."

"How many?"

"July [-] Incident."

"Did it start so early abroad?"

"Now they are all 'printed boards', that is, green circuit boards. Plug-in PCBs have been eliminated as early as ten years ago. Moreover, printing technology has also changed from flat packaging to ball array packaging, high development in the direction of density."

"Hey, I just want to control the sound, why make it so complicated."

"Right."

The physics teacher sat at the operating table and after learning about many raw materials, "Let's start with a small speaker?"

"I'll watch you make it. If you need anything, just ask."

"No, let's talk about your requirements first, what kind of tone you need."

Xu Fei dug out Zhang Fei from the cabinet, which had not yet been successfully developed, "His."

"Mechanical Zhang Fei?" The physics teacher seemed to know this toy, nodded, "Is there a metal film?"

"What kind of material?"

"The harder the better."

"Phosphor bronze?"

"I've never heard of it, it's best to use a titanium metal diaphragm... In this way, I will list the corresponding materials, and you can see what you can prepare."

After half an hour.

The physics teacher first made the voice coil, then fixed the magnet, and then set the front pole piece, the back pole piece, and the centering support piece.

Then, according to Lou's father's suggestion, we studied the 'hanging edge', which is used to provide damping, so that after the signal disappears, the sound radiation can also be quickly eliminated to ensure high sound quality.

Then the diaphragm, dust cover...

"In general, this is a moving coil unit, which is slightly more complicated than the electromagnetic unit you made. The principle is that the output signal of the recording interface will activate the current of the amplifier, and the positive and negative electricity of the current will make the unit go up. The coil produces a magnetic field response. ++ Repulsive diaphragm retracts inward, +- diaphragm expands outward, one retracts and one expands to form a sound."

Xu Fei imitated making one, and soon got a reminder from the base.

[Titanium Alloy Horn-Subwoofer]
View parameters:

Distortion, signal-to-noise ratio, frequency response, dynamic range, compliance characteristics, stereo separation, direct sound, reflected sound, reverberation sound, reference oscillation, auditory characteristics...

If we say that the previous small speaker was 1, it has reached 99 now.

At the same time, the physics teacher and Lou's father worked together to improve the recorder, design and adjust it to match the circuit diagram for the sound of "Mechanical Meng Zhang Fei".

Another half hour later.

The four old men installed batteries, stereos, players, and circuit boards for Zhang Fei.

Xu Fei twisted it hard, and the power was activated at this time. If the power of the mainspring is exhausted, it will automatically turn off the power.

"With the help of a teacher, it really gets twice the result with half the effort."

Then, let go of Zhang Fei.

"Wow~~~"

The mechanical Zhang Fei held the Zhangba Snake Spear in his right hand and clenched his fist in his left hand. After posing, he charged forward with the weapon in his hand.

The sound is like Optimus Prime, full of heavy metal texture, with a little echo at the same time.

It seems that it is indeed more selling point than the silent version.

However, the teacher of Yuhong Class frowned slightly, "It's like singing an opera, and it doesn't reflect Zhang Fei's fierceness."

Lou's father nodded, "It should be full of murderous intent. Is it an enemy of ten thousand people? It is much more fierce than Guan Yu."

The teacher of Yuhong Class, who is over [-] years old, pondered for a moment, his eyes lit up, he picked up the recorder, and lowered his throat:

"I kill, I kill, I kill kill kill~~~ Hahahaha!"

A dull and hoarse voice echoed in the workshop.

Xu Fei had goosebumps all over his body.

Lou's father and the physics teacher also had ghostly expressions on their faces.

The teacher of Yuhong class put down the recorder and smiled confidently, "How is it?"

"Absolutely!"

Xu Fei hurriedly copied the magnet sheet.

The teacher of Yuhong class stopped him and said, "The movement is not right either. You should slash wildly, like a wind blowing away, and finally hold the wine jar, looking up to the sky and laughing heartily."

"This suggestion is worth 5 red notes... No, I will give you a commission. Every time you sell one, you will get [-] cents."

"No, I think I'm suitable to come to your company to make toys."

"Ok?"

"I've been the king of kids all my life, but I lost my job in the end."

"???"

Lou's father explained: "Now the red class is not established, but the small class is changed. Lao Jia has no teacher qualification certificate, and he has no pension when he retires."

"Your dubbing is enough for you to retire in the company."

"No, I think I can dub more characters, Huang Zhong, Wei Yan, Cao Cao...Although I don't understand them, I understand young people better."

"Sit down quickly, let's continue."

The physics teacher looked at the time, "Would you like to go back and drink?"

"Send the food over, drink while researching, wouldn't you be more inspired?!"

After Xu Fei finished speaking, he gave Da Ma a wink.

The latter returned to finance and brought three bank cards with a limit of [-].

"One card per person, eight zeros in the password, don't refuse, this is money from a foreign company, don't take it for nothing."

"I can't ask for this." Lou's father blushed slightly, and refused, "I originally invited you to thank you for finding a good job for Xiaohu, and Nan Nan has also become a regular, so what is it now?"

"Hey, how polite are you? The timbre and dubbing of our follow-up characters have to be remade. If they are done well, the cards will be indispensable."

"Are all foreign companies so rich and powerful?"

"No, this is a copyright buyout, which will be used in animation, games, and even movies in the future."

Xu Fei took out his mobile phone and notified the design consulting company to copy the magnet sheet and make Zhang Fei's promotional video as quickly as possible.

The Three Kingdoms Smash Bros. will start on the 20th. Today is the 16th. It takes four days, so it’s a bit rushed.

Soon, Tang Mo ran over in person, "Director!"

"Listen to Zhang Fei's dubbing."

Xu Fei worked hard on the mechanical toy again.

After Zhang Fei landed...

"I kill, I kill, I kill kill kill~~~ Hahahaha!"

"This!"

Tang Mo's eyes widened suddenly, "This sentence alone is enough to create a complete image, but can you add a few more paragraphs?"

The teacher of Yuhong class pondered slightly, raised his chest, and said in a loud voice: "An easy man is like Yi De, and he will punish the heartless people in the world!"

"Humanity is snobbish and snobbish, who knows that heroes are white? This can be used as Zhang Fei's static lines."

Xu Fei thought for a while, "'Here is Zhang Fei from Yan, who dares to fight to the death with me' and the like, can be launched later, the unparalleled version of Mechanical Three Kingdoms, two lines of lines, two sets of actions are tentatively scheduled, and the promotional film will be published within three days. Make it out, and take advantage of the heat of the Three Kingdoms Smash Bros. to launch the 'Mushuang Mechanical Zhang Fei'."

"Good factory manager."

Tang Mo turned around and said goodbye.

Xu Fei picked up Zhang Fei and calculated the cost.

Horns occupy a production line.

The player occupies a production line.

The internal structure of Wushuang Machinery Zhang Fei is complicated. Even if the assembled version is not used, the manufacturing difficulty is still not low.Huangnigang Toy Factory produces speakers and players, and Daze produces Wushuang Machinery Zhang Fei. According to the total safe power, the daily output should not exceed 1 sets.

At present, the three countries of general machinery ship 36 sets per day, with sales of about 320 million.

If it remains profitable, the price cannot be lower than 320 red notes.

However, there is a cost for research and development, and the speaker uses titanium alloy, coupled with the "iron magnetic sheet sound storage" technology, as well as creativity, dubbing and so on.

Domestic 600 red notes start, Wadao and Nanbangzi at least 1200 red notes...

With such a high price, I don't know if anyone will buy it.
