Bright Sword: Starting from the Improved Grenade

Inside the semiconductor laboratory.

"What I'm asking you to make this time is called an electronic amplifier circuit board."

Zhao Tianyang stood in front of a blackboard, drawing a diagram and explaining: "First, we need to prepare transistors, resistors, capacitors, circuit boards, and dry batteries."

(Use epoxy resin as the board, cover it with a layer of copper foil as the conductive layer of the circuit, and then apply a layer of insulating paint to protect the areas on the circuit board that do not need to be soldered)

(Zinc: negative electrode material, manganese dioxide and graphite powder are mixed to make the positive electrode, ammonium chloride and zinc chloride are made into an aqueous solution as the electrolyte, and carbon rods are used as the positive electrode current collector.

(Finally, put them together and it becomes a 1.5V dry cell battery!)

"Finally, just assemble them according to this circuit diagram." After finishing the explanation, Zhao Tianyang handed the laboratory to the technician and called Luo Peilin out.

"How is it? Are you used to it here?"

"good!"

Luo Peilin nodded: "Although we can't get in touch with the front line here, the semiconductors we produce and the radars we research are of great help to the war of resistance."

“I get so excited just thinking about it.”

"Haha, just get used to it."

Zhao Tianyang pointed to the factory next to the semiconductor laboratory and asked: "How is the production of semiconductor parts now?"

“It’s on track.”

Although he said that things were on the right track, Luo Peilin still said with regret: "It's a pity that semiconductor manufacturing is quite sophisticated, and it's not easy to train workers."

"It is also very difficult to build a semiconductor factory. Up to now, we can only barely meet the needs of the laboratory."

"Take your time, it will be fine."

Zhao Tianyang knew that in order to mass-produce semiconductor parts, in addition to having qualified factories, he also needed a group of well-educated workers, so there was no point in being anxious.

"Minister, it's done."

At this time a technician came out and said.

"it is good."

Zhao Tianyang threw away the cigarette he had been smoking for who knows when and walked into the laboratory: "Prepare zinc sulfide (phosphor), glass substrate, and metal film."

Ten minutes later, all the materials were ready, and Zhao Tianyang came to the front of the crowd and began to direct.

"Now wipe the glass substrate with alcohol to make sure it is clean and flat, then apply zinc sulfide evenly on the glass substrate."

"Finally, the metal ions are reduced to metal through chemical plating and deposited on the glass substrate to form an electrode."

As Zhao Tianyang was talking, the technicians were working on it. Everything went smoothly at first, but when it came to the last step of preparing the basic electrode on the glass, something went wrong!

First, the metal is not stirred evenly, which leads to local concentration differences and uneven coating.

Later, the temperature was controlled too high, causing the plating solution to decompose. This series of operational errors made the atmosphere in the laboratory tense.

"Haha, it looks like everyone is a little tired."

Zhao Tianyang smiled gently: "Let's go out and smoke a cigarette to relieve the mood."

"That's right, everyone, take a break first. Only by combining work and rest can we do the experiment better!"

Luo Peilin on the side quickly echoed.

After coming out, Zhao Tianyang took out a pack of Huanghelou cigarettes and handed it to the technician beside him: "Who wants to smoke? Come and get it yourself!"

"Yellow Crane Tower!"

A technician who liked smoking quickly took the cigarette and gave one to each of the people.

Soon, people started smoking outside the laboratory. Of course, there were also technicians who did not smoke. They squatted aside and discussed the mistakes that had just happened, far away from them.

Half an hour later, everyone returned to the laboratory.

With the relaxation just now, this experiment went much more smoothly, and in less than a moment a fluorescent screen with prepared upper electrodes was made.

"Hurry up and cover it with epoxy resin to prevent the fluorescent screen from being contaminated."

Zhao Tianyang urged.

"What's the minister doing next?"

After completing the manufacture of the fluorescent screen, the technicians looked at Zhao Tianyang with great interest, eager to start the next experiment.

“Of course it’s assembled.”

Zhao Tianyang took out a photomultiplier tube from the box: "Connect this photomultiplier tube to the electronic amplifier circuit board and the fluorescent screen."

“Don’t forget to add lens reflectors to collect and focus the low light in the environment.”

An hour later, Luo Peilin was puzzled as he looked at the thing in front of him with exposed wires and each component having to be held by someone.

"Minister, what on earth is this?"

“It’s called night vision.”

Zhao Tianyang explained casually and ordered: "Someone turn off the lights in the laboratory, close the door, and draw the curtains."

When all the light sources disappeared, only dark figures could be seen in the laboratory.

Zhao Tianyang turned on the power switch, and the fluorescent screen in Luo Peilin's hand lit up, revealing several green shadows.

"Look!!"

A scream rang out, and a technician pointed at the screen and said in horror: "There is a ghost!"

"Pop, there's a head, it's a human figure!"

In order to prevent a panic, Zhao Tianyang slapped the shouting technician on the head.

"Don't be nervous, what we just made is called night vision goggles."

"Its function is to amplify the weak light in the environment to form an image. Because our eyes are more sensitive to green, it is made into a green image!"

"This is a night vision device! It's amazing!"

"show me!"

"Amazing!"

After listening to Zhao Tianyang's explanation, the crowd, who were originally a little panicked, calmed down and crowded in front of the fluorescent screen to watch.

"Hey, why is it dark?"

The fluorescent screen, which had a swaying figure on it, suddenly dimmed.

"Maybe the power is out!"

Zhao Tianyang took out the dry battery, bit it twice, and reinstalled it.

"It's on. It's on again."

"hehe."

Zhao Tianyang smiled and gave his seat to the technicians so that they could all study the night vision goggles up close.

Seeing this, Luo Peilin hurriedly handed the night vision goggles to the technician beside him and followed Zhao Tianyang out.

"You should have guessed the principle of this night vision device, right?"

Zhao Tianyang stood outside the laboratory and asked Luo Peilin.

"Yeah, it's an application of the principle of light."

Luo Peilin nodded and said, "Although the visible light in the dark is very weak, the infrared light that is invisible to the human eye is very abundant."

"Using infrared devices, we can amplify the faint light in the dark and see objects in the dark through the fluorescent screen."

"That's pretty much it!"

Zhao Tianyang smiled and asked, "I plan to hand over the follow-up research and production of night vision devices to you. Do you have the confidence?"

"no problem!"

Luo Peilin nodded happily at the opportunity to research and produce such high technology.

"And now the only countries that can develop night vision goggles are Germany and the United States. The research and production of night vision goggles must be kept secret."

"You must set up your own security team. No outsiders are allowed to approach here."

Zhao Tianyang put on his coat and finally said, "I'll assign you a task now, which is to develop vehicle-mounted night vision goggles and head-mounted night vision goggles."

"Row."
