Guan Fei stood behind a technician with his hands tied up and watched as he intently soldered the processor's pins to a double-sided circuit board following the circuit diagram. Pen %Fun %Pavilion www.biquge.info±,

The processor, naturally, is the Chinese processor he just got back from the semiconductor research institute.

In this era, computers are still played by professionals, and they have never considered that ordinary people can disassemble them, and there is no room for DIY, so there are not so many convenient sockets. All components, including processors and memory, are soldered directly to the circuit board.

If something goes wrong with the computer, the user will turn to the manufacturer instead of repairing it themselves.

Since there are no accessories, Guan Fei is not interested in developing a socket that cannot be sold. So this processor had to be soldered directly to the circuit board in the traditional way.

The board is less than 20 centimeters long and 10 centimeters wide, about the size of an adult man's palm.

With such a small area, it naturally can't accommodate too many components. Therefore, a double-sided circuit board is used, the front and back sides are soldered, and most of them are integrated circuits, and only a few auxiliary circuits use traditional independent components.

The processor is located in the middle of the circuit, and there is a row of four integrated circuits that have been soldered below. Judging from the surface identification, it is the memory produced by the Japanese Sharp company, with a capacity of 32K each.

Although the pins themselves are very new, in order to ensure the quality of welding, each pin is carefully polished to remove the rust on the surface. Then dip it in the flux, lightly smear a layer of solder on the surface, and do the preliminary tinning work.

With this layer of tin plating, the tin will be easier to fuse and the soldering will be stronger.

His movements are not fast, but they are gentle, and each solder is crisp. The solder joints formed after welding are small, the surface is rounded, and there are basically no spikes formed by dragging.

Guan Fei watched silently with his hands behind his back, thinking about the precarious situation of the military division, and he soldered the first arcade circuit board made in Hong Kong. In the blink of an eye, the military sub-district did not realize that it was already quite large-scale, and all kinds of talents under his command had come out in large numbers, and there was no need to rely on him alone.

After completing the last solder joint, the technician waits for a while, waits for the temperature to drop, confirms that there is no false soldering one by one, and then brings a multimeter, pin by pin for final inspection.

"Commander, it's done! There is no problem with the detection. After all the tests passed, the technician wiped the sweat on his forehead, pinched the edge of the circuit board with his hand, put it in the sponge cushioned box, and handed it over with both hands.

"Thank you! Thank you! Guan Fei repeated the check, confirmed that it was indeed completed, and thanked him with a smile.

……

On the anti-static rubber tabletop, there are lenses, optical lenses, belt transport mechanisms and other parts, and a Sony-made beta video tape that has been disassembled, leaving only the tape part.

Many of these things are imported from Hong Kong.

The military sub-district can only be said to have a preliminary manufacturing capacity, and it cannot be said that these things in front of them will never be able to be made, but the cost will definitely be terrifyingly high. And at the speed of self-made high-precision manufacturing equipment, it will not be possible to do it in two or three years.

I don't have it, of course, I bought it, Guan Fei has no mental cleanliness in this regard.

"Tube!" Guan Fei was wearing a dust-free suit, stretched out his right hand, and said in a dull voice through the mask.

The assistant handed him a lens barrel made of lightweight aluminum alloy with a matte insulating coating on the surface to replace the original plastic lens barrel. Engaged in these high-precision operations, they are not able to intervene for the time being, and can only act as assistants.

Guan Fei took the lens barrel and gently checked it, the total weight of the retractable lens barrel was about thirty-one grams, which was at least twenty grams lighter than the original plastic lens barrel.

The lens barrel is made with extremely high precision, the surface is smooth, and the telescopic is very smooth.

With his rubber-gloved hands, he twisted the lenses, gently inserted them into the frames, carefully adjusted them, and then slowly twisted the screws to fix them.

"Servo motor!" After confirming that the lenses had been accurately positioned, he stretched out his hand again and said softly.

A small and delicate servo motor was handed to him.

This is a special product of the military sub-district electric motor factory, which can ensure that the minimum advance scale is about one micron. Guan Fei took the servo motor, meticulously completed the installation, and then reached out again and asked the assistant to hand him the next part to be assembled.

As Guan Fei put his heart and soul into it, time passed minute by minute, and there were fewer and fewer scattered parts on the table, until the last part was also installed in place.

"Whew!"

Guan Fei let out a long breath, forming a white mist on his mask.

The specific work is actually handed over to the biological subbrain, including the design drawings and installation progress are controlled by the biological subbrain. However, the assembly of the camera is a very delicate task, and even the biological side brain cannot be carried out very quickly.

After ten hours of assembly, his tense muscles became extremely sore, and his whole body seemed to be drained, making him want to sit down and get a good night's sleep.

However, the ten hours of work were not in vain, and the use of TV-grade optical lenses, mechanical belt handling mechanisms, camera circuits with audio removed and only video recording functions, control circuits, power circuits, etc. were finally assembled. An ultra-light camera weighing only 903 grams was finally born.

This camera can perform 10x optical zoom, can zoom automatically, has anti-shake image compensation function, and the image recording quality meets the NTSC standard. The indicators are not the same as those of the home cameras launched by JVC, and even compared with TV-grade cameras, they are only slightly inferior.

A large number of purchased parts, a small number of self-modified and replaced parts, this is also the level.

It's not that a better camera can't be made, it's that it's not necessary.

The total weight of almost ten kilograms is too heavy compared to the later DVDs. However, in this era, even if Guan Fei is willing to use memory, with a storage capacity of only tens of kilobytes, it is necessary to meet the needs of at least one hour of digital image recording, which is much heavier than that of traditional tape recorders.

Under the current conditions, this is the best option.

……

"Shot!" Guan Fei stretched out his hand, and the assistant next to him quickly handed over a piece of Leica optical lens made in West Germany.

Don't get me wrong, Guan Fei isn't just doing a repetitive job and assembling another camera. The same is the optical lens, which is used on cameras.

He is now equipped with an auto-controlled camera, which can take pictures at a constant speed of 10 seconds, or he can press the shutter continuously at a speed of 1 second per second. As long as the film can keep up, it's okay to shoot continuously until the battery runs out.

Compared with the complexity of the camera, the automatic camera is much simpler, and the entire assembly work is completed in less than ten minutes.

……

The assembly workshop on the first floor of the laboratory building of the headquarters.

In the center of the spacious workshop, on the assembly table, a fixed-wing aircraft with gray paint is quietly parked.

The fuselage of the aircraft is square, which is the traditional box type, and the wings are located in the upper part of the fuselage, which is known as the upper wing. The whole aircraft looks decent, and there is nothing unusual about the design.

However, the size of this aircraft is not large, it is only 398 centimeters long, with a wingspan of 7.8 meters, and a height of 72 centimeters with the non-retractable landing gear.

There are no seats in sight on the plane, a flat box type.

That's right, this is a model airplane.

However, now Guan Fei and others are going to perform major surgery on it, add power devices, camera devices, camera devices, and navigation devices, and convert it into an unmanned reconnaissance plane!

Because the overall design is from Guan Fei, the corresponding space has already been reserved on this model aircraft to install various accessories. In the era when the size of electronic products cannot be miniaturized, in order to be able to install all the accessories on the drone, the fuselage adopts a box-shaped design, sacrificing flight performance to meet the needs of space.

The trim work has been completed at the time of design, and each fitting is also manufactured in strict accordance with the design to ensure the stability of the center of gravity.

In the belly of the camera, holes are also reserved to poke out the camera and camera lens.

This assembly does not require a clean environment, including Guan Fei, and everyone is no longer wearing stuffy dust-free clothing. A group of young men walked around the plane, looking at the various accessories placed next to the assembly table, and their faces were irrepressibly excited, it was Zou Yongdong, who usually behaved very calmly, and he was also smiling and eager to try at the moment.

What kid doesn't have a dream of flying?

As a race that can only be down-to-earth and run on the ground, it has an irrepressible yearning for flying into the sky.

The bamboo dragonflies, kites, and Kong Ming lanterns they played with when they were children are all human beings' desire to fly. It's just that the plane is so small, like a toy, that it is obviously impossible to carry people. Even if it can fly with a load of tens of kilograms, everyone is a little skeptical.

"Everyone is in place, now, let's carry out the final assembly work!" Guan Fei looked at everyone's eager expressions, clapped his hands as he wished, and began to distribute work, "First of all, the power part!" ”

Zou Yongdong and other power manufacturing teams hurriedly used a trolley to launch an assembled star-shaped piston engine and ran over.

The engine weighed twenty kilograms, and a young technician couldn't wait, and one person picked it up. Zou Yongdong and the others paused in frustration, regretting that they were moving slowly and did not seize this opportunity.

Guan Fei smiled and did not interfere with their play.

This time, he didn't do it himself, but stood by and instructed everyone to load the engine into the nose along the slide.

Playing is playing, and everyone is still very serious about doing things.

After the engine was placed in the predetermined position, various measuring devices were placed in place, and after carefully measuring from all angles, it was carefully fixed with electric welding. Next up was the oil connection, a kind of technician who was in high spirits and used a copper fuel pipe to connect the wing fuel tanks to the engines.

Before the engine was installed, the nose was still a little upturned, and it looked a little floating.

But when the engine was in place, the nose sank slightly under the action of twenty kilograms, and then re-stabilized under the gravitational drive of the rear tail.

When the aluminum alloy propellers were also assembled, an airplane appeared in front of everyone.

Click, click, click!

A technician holding a camera and pressing the shutter hard before and after the film, recording the scene of everyone's work.

Zou Yongdong with a focused expression and tightening the screws; Zhang Dongbei, who was covered with oil and couldn't take care of wiping it; Tan Feng, who drilled down to measure the balance of the fuselage, ...... everyone, was taken by him many photos, some close-ups, and many were group photos of everyone in it.

"Navigation system!"

Zou Yongdong and others completed the engine installation and immediately made way for the navigation team to install the gyroscope to the reserved position.

This unmanned reconnaissance aircraft does not have advanced navigation equipment, and relies entirely on this gyroscope for position positioning. It can't do precise positioning, and the navigation error is calculated to be about 100 meters. It is impossible to achieve precise guidance, but military sub-divisions are not yet able to control the flight route from an ultra-long distance, and the reconnaissance plane relies entirely on program control of the flight route, and if it does not, it is estimated that it will never come back.

With it, at least you know where to fly, you won't be wrong in the general direction, and you can return. When you get close to visual distance, you can land by radio remote.

"Control circuits!" The navigation equipment was quickly assembled, and they volunteered to make way for the control team to install the control circuits.

The control circuit, which is no more than 20 centimeters long, is screwed to an alloy bracket vertically. After all the lines are connected, the antenna in the protective case is led out from the upper end of the body, and after the tail is fixed, the circuit board is covered with a thin metal box to shield from external radio interference.

This kind of simple and primitive unmanned reconnaissance aircraft is just a temporary makeshift use, and it is not intended to be used for a lifetime. Besides, the Ding Army and other armed forces around them have no scientific and technological ability, and they just bully children, so it is enough to simply protect them.

The circuits of cameras and cameras are also grouped next to the control circuits to save space. The control cables connect them to the control panel for program control.

Cameras, cameras, and only these are the functional accessories.

As for the real-time monitoring of those tall things throughout the whole process, the military sub-district really can't play it. Being able to make this unmanned, automatic camera, and photographic reconnaissance plane, fly into the sky, and return smoothly is already the highest crystallization of existing technological strength.

A thousand miles away starts with a single step.

If you want to play real-time monitoring and operate the whole process visually and remotely, it is absolutely impossible without a long period of technological accumulation at the speed of development of military subdivisions.

The final assembled aircraft was not pretty, but everyone was smiling and proud and loved it.

For them, this do-it-yourself unmanned reconnaissance aircraft is the most beautiful thing in the world!
