Guan Fei stood behind a technician with his hands, watching him concentrate on welding the pins of the processor on a double-sided circuit board according to the circuit diagram. ±

The processor is naturally the Chinese processor he got back from the Semiconductor Research Institute.

In this era, computers are only able to play with professionals. They never considered allowing ordinary people to disassemble them, and there was no space for DIY, so there were not so many convenient sockets. All components, including processors, and memory were directly soldered to the circuit board.

If there is a problem with the computer, the user will turn to the manufacturer instead of doing the repairs themselves.

Since there are not even accessories, Guan Fei is not interested in developing a socket that cannot be sold. So the processor has to be soldered directly to the circuit board in a traditional way.

The circuit board is less than twenty centimeters long and ten centimeters wide, which is about the same size as an adult male slap.

Such a small area naturally cannot accommodate too many components. Therefore, the double-sided circuit board is used, the front and back are soldered, and most of them are integrated circuits, and only a few auxiliary circuits use traditional independent components.

The processor is located at the upper part of the middle of the circuit, and there is a row of four soldered integrated circuits below. Judging from the surface marking, it is a memory produced by Sharp, Japan, with a capacity of 32k per block.

The technicians have learned a good craft. Although the pins themselves are very new, in order to ensure the quality of the soldering, each pin is carefully polished to remove the surface rust. Then they dipped it in the flux, gently applied a layer of solder on the surface, and did the preliminary tin plating work.

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

His movements are not fast, but they are very gentle, and the solder is very clean every time. The solder joints formed after welding are very small, with a round surface, and there are basically no spikes formed by drag strips.

Guan Fei looked silently with his hands behind his back, thinking about the first arcade circuit board he made in Hong Kong was soldered by him. In a blink of an eye, the military district had already become quite large, and all kinds of talents were produced under his command, so he no longer had to rely on him alone. He felt that time was like water.

After completing the last solder joint, the technician waited for a while, and waited for the temperature to drop, and confirmed that there was no false soldering one by one, then used the multimeter, one pin at a time for the final inspection.

"Commander, welded it! There is no problem with the inspection." After all the inspections, the technician wiped his forehead and sweated slightly. He held the edge of the circuit board with his hands, put it in a sponge-cushioned box, and handed it over with both hands.

"Thank you! Thank you for your hard work!" Guan Fei repeated the inspection, confirmed that it was indeed completed, and thanked with a smile.

...

The anti-static rubber desktop is filled with lenses, optical lenses, belt mechanisms and other parts. There is also a plate of Sony-made beta video tapes that are disassembled and only have the tape parts left.

Many of these things are imported from Hong Kong.

The Military Sub-district can only be said to have initial manufacturing capabilities now. These things in front of us cannot be said to be absolutely impossible to make, but the cost will be terrible. Moreover, with the speed of making this batch of high-precision manufacturing equipment, it will not be able to make it in less than two or three years.

If you don’t have it, of course you can buy it out. Guan Fei has no mental cleanliness in this regard.

"Lens tube!" Guan Fei was wearing a dust-free suit, stretched out his right hand, and said dullly through the mask.

The assistant handed him a lens barrel made of light aluminum alloy material and sprayed with a layer of matte insulating paint on the surface to replace the original plastic lens barrel. They were unable to insert these high-precision operations for the time being and could only act as assistants.

Guan Fei took the lens barrel and gently weighed it. The total weight of the retractable lens barrel was about 31 grams, which was at least twenty grams lighter than the original plastic lens barrel.

The lens barrel has extremely high production accuracy, smooth surface, and very stable expansion and contraction.

He used his hand with rubber gloves to twist the lens, put it gently into the frame, carefully adjust it, and then slowly twist the screws to fix it.

"Servo motor!" Through the biological auxiliary brain, confirming that the lens had been accurately positioned, he stretched out his hand and said softly.

A small and exquisite servo motor was handed to his hand.

This is a product specially made by the Military Sub-district Motor Factory, which can ensure that the minimum forwarding scale is about one micron. Guan Fei took the servo motor and completed the installation meticulously. Then he reached out and asked his assistant to hand him the next part to be assembled.

As Guan Fei devoted himself to his full enthusiasm, time passed by minute by minute, and there were fewer and fewer parts on the table, until the last part was installed in place.

"call!"

Guan Fei let out a long breath and formed a white mist on his mask.

The specific work is actually handed over to the biological auxiliary brain, including the design drawings, and the installation progress is controlled by the biological auxiliary brain. However, the assembly of the camera is a very delicate job, and even the biological auxiliary brain cannot proceed much faster.

After ten hours of assembly, the tense muscles became extremely sore, and the energy in his body seemed to have been drained, making him want to sit down and have a good sleep.

However, the ten hours of work were not in vain. The use of TV-grade optical lenses, mechanical belt-leading mechanisms, and the camera circuits, control circuits, power circuits, etc. that remove the audio and retain the video recording function, were finally assembled. An ultra-light camera weighing only 903 grams was finally born in his hands.

This camera can perform ten times optical zoom, can zoom automatically, has anti-shake image compensation function, and the image recording quality reaches the NTSC standard. The various indicators are simply incomparable to the home cameras launched by JVC. Even compared with TV-level cameras, it is only slightly inferior to those of the TV-level cameras.

A large number of purchased parts and a small number of self-transformed and replaced parts are at this level.

A better camera is not that it cannot be made, but that it is unnecessary.

The total weight of nearly ten kilograms was too heavy compared to the later DVs. However, in this era, even if Guan Fei was willing to use memory, with a storage capacity of only a few dozen kbs, it would meet at least one hour of digital video recording, which was much heavier than traditional tape recorders.

Under current conditions, this is the best choice.

...

"Lens!" Guan Fei reached out and his assistant quickly handed over a West German-made Leica optical lens.

Don't get me wrong. Guan Fei is not doing repeated work and assembling another camera. It is also an optical lens, which is used on the camera.

What he is assembled now is an automatically controlled camera that can take pictures at a speed of ten seconds at a constant speed, or you can continuously press the shutter at a speed of one second. As long as the film can keep up, it will be fine to continuously shoot the battery exhausted.

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

...

The first floor assembly workshop of the headquarters experimental building.

On the assembly table in the wide workshop, a fixed-wing aircraft with gray painted surface was quietly parked.

The aircraft's fuselage is square, which is a traditional box-shaped aircraft. The wings are located on the body of the fuselage, which is the so-called upper single wing. The entire aircraft looks average, but there is nothing surprising in its design.

However, the aircraft is not large in size, only 398 cm long, with a wingspan of 7.8 meters, and a 72 cm high in the landing gear that cannot be retracted.

There is no seat on the plane, it is a flat box shape.

By the way, this is a model plane.

However, Guan Fei and others are now going to perform major operations on him, add power devices, camera devices, photography devices, and navigation devices, and convert them into an unmanned reconnaissance aircraft!

Because the overall design comes from Guanfei, corresponding space has been reserved on this model aircraft to install various accessories. In an era when electronic products cannot be miniaturized, in order to be able to install all accessories on the drone, the fuselage adopts a box design, sacrificing flight performance to meet space needs.

All trimming work is completed during design, and each accessories are strictly manufactured according to the design to ensure the stability of the center of gravity.

A hole is also reserved on the belly of the machine to poke out the camera and camera lens.

This assembly does not require a very clean environment. Including Guan Fei, no one was wearing a stuffy dust-free suit. A group of young men were spinning around the plane and looking at the various accessories placed next to the assembly table. The excitement on their faces was uncontrollable. Even Zou Yongdong, who usually acted calmly, was smiling and eager to try.

Which child doesn’t have a dream of flying?

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

The bamboo dragonflies, kites, and Kongming lanterns they played with when they were young were all human desire for flying. However, this plane is so small, like a toy, and obviously cannot carry people. Even if it can fly with a load of dozens of kilograms, everyone is a little doubtful.

"Everyone is here, now, let's do the assembly work!" Guan Fei looked at everyone's anxious expressions, clapped his hands as he wished, and began to assign work, "First of all, the power part!"

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

The engine weighed 20 kilograms, and a young technician couldn't wait, so he picked it up alone. Zou Yongdong and others paused in annoyance, regretting that he had slowed down and did not get this opportunity.

Guan Fei smiled and did not interfere with their play.

This time he did not do it himself, but instead stood by and guided everyone to put the engine along the slide rail into the nose.

Even though we are playing, we are still very serious about doing things.

After the engine was placed in the predetermined position, everyone placed various measuring equipment, carefully measured from various angles, and then carefully fixed it with electric welding after confirming it was placed in place. Next was the oil circuit connection, a kind of technician was very excited and connected the wing oil tank to the engine using a copper oil pipe.

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

However, when the engine is installed in place, under the action of twenty kilograms of weight, the nose sinks slightly, and then stabilizes again under the gravity of the rear tail.

When the aluminum alloy blades were also assembled, an airplane appeared in front of everyone's eyes as if it were.

Click to scratch!

A technician held the camera in his hand, not hesitating to film, pressing the shutter forward and backward hard to record the scene of everyone working.

Zou Yongdong, who was focused on his expression and tightened the screws; Zhang Dongbei, who was covered in oily face and didn't care about rubbing it; Tan Feng, who fitted down to measure the balance of the fuselage... He took many photos of everyone, including close-ups, and many photos of everyone in it.

“Navigation system!”

Zou Yongdong and others completed the engine installation and immediately gave way to the navigation team and asked them to install the gyroscope in the reserved position.

This unmanned reconnaissance aircraft does not have advanced navigation equipment, and it relies entirely on this gyroscope for positioning. It cannot achieve precise positioning. After calculation, the navigation error is about 100 meters. It cannot achieve precise guidance, but the military sub-district is not able to control the remote control at a long distance. The reconnaissance aircraft relies on program control of the flight route. If it does not, it will probably never come back if it flies out.

With it, at least you know where to fly. You won’t be able to make mistakes in the big direction and you can return. When you get close to the visual distance, you can land via remote control via radio.

"Control circuit!" The navigation equipment was quickly assembled, and they took the initiative to give way to the control team and asked them to install the control circuit.

The control circuit, which is only twenty centimeters long, is fixed on an alloy bracket with screws. After all the lines are connected, the antenna in the protective sleeve is pulled out from the upper end of the machine and pulled until the tail is fixed, the circuit board is covered with a thin metal box to shield the interference of external radio waves.

This simple and primitive unmanned reconnaissance aircraft is just a temporary use, and it is not intended to be used for a lifetime. Besides, the other armed forces around them do not have much technological capabilities and are just bullying children. It is enough to take such a simple protection.

The camera and the camera's circuit are also centrally installed next to the control circuit to save space. The control cable connects them to the control panel to achieve program control.

Camera, camera, and only functional accessories are just these two.

As for real-time monitoring of high-end things throughout the entire process, the military sub-district really can't play with it. Being able to make this unmanned, automatic camera, and photo reconnaissance aircraft, fly into the sky, and return smoothly is already the highest crystallization of existing technical forces.

A thousand miles away begins with a single step.

If you want to play real-time monitoring and visually remote control throughout the whole process, it is impossible to do without long-term technical accumulation.

The final assembly of the aircraft is actually not beautiful in appearance, but everyone laughs happily and proudly, and can't let go of it.
Chapter completed!
