Chapter 727: Making a TV During the break, Lu Qingyang was organizing his notes when he heard a noisy discussion in the corner of the classroom.
He looked up and saw his classmate Wang Hongzheng being surrounded by several classmates who usually liked to hang around him. He had an undisguised look of boasting on his face and was talking about something with saliva flying all over his body.
"...Hey, you haven't seen it, that thing is really impressive!"
Wang Hong exaggeratedly gestured with his hands to form the shape of a small square box.
"When the electricity is turned on, images appear on the glass in front of me. There are people singing, dancing, and even performing operas. It's exactly like watching a movie. It's playing in my living room."
He was afraid that others hadn't heard. "I just moved back last night. It's the only one of its kind in the entire cadre family compound. My dad used all his connections to get the ticket!"
Several listeners around him made exclamations of admiration and envy at the right time, such as "Wow", "Really?" and "That's amazing", which greatly satisfied Wang Hong's vanity and made him hold his head even higher.
Zhou Zhe was sitting next to Wang Hong, sorting books. He came from a remote mountain village. Not to mention big things like televisions, their village didn't even have electricity, and they relied on kerosene lamps for lighting at night.
He couldn't help but turn his head and asked cautiously, "Wang Hong...then, then this TV...is it expensive?"
"Expensive? Haha, that's a funny question! This thing, just having money? Humph, even if you have money you can't buy it, you need tickets and connections, understand? This is not something you guys in the village are thinking about."
Zhou Zhe moved his mouth but ultimately said nothing. He just stood up silently and prepared to leave.
Wang Hong looked at Zhou Zhe's extremely embarrassed expression and snorted smugly.
"Isn't it just a TV?"
Everyone looked in the direction of the voice and saw that Lu Qingyang, who was sitting in the front row, had put down his pen at some point. He turned around and his gaze passed across half the classroom and fell directly on Wang Hong and Zhou Zhe.
Wang Hong was stunned for a moment, then sneered: "Hey, Lu Qingyang, you're talking lightly! It's just a TV? You know this..."
His words were interrupted by Lu Qingyang.
"Do you believe it or not? I can build one for you."
“…”
The whole classroom fell into silence in an instant.
You can hear a pin drop.
Everyone thought they had heard wrongly.
Build...build one?
The smug look on Wang Hong's face froze instantly, as if he had just heard the most ridiculous joke in the world.
His followers also looked at each other in disbelief.
"Hahaha, build it? Lu Qingyang, are you crazy? You think this is just clay kneading? Building a TV? Do you know what that is? Even our school lab doesn't have many decent equipment! Just you? What are you going to use to build it? Use your mouth? Hahaha, I'm dying of laughter. Zhou Zhe, do you believe he can build it for you? Hahaha!"
Wang Hong laughed so hard that tears were almost coming out.
Several of his followers also laughed.
Wang Hong's laughter echoed in the classroom. Zhou Zhe's face was already red to his ears, and he wished he could find a crack to crawl into.
He was grateful to Lu Qingyang for standing up for him, but he also felt that Lu Qingyang's words were too confident and unrealistic.
"The lab equipment is simple, but the basic principles are there. Picture tubes, deflection coils, high-frequency heads, circuit boards... it's just a matter of assembling and debugging these components according to the principles in the drawings. What's the problem?"
Wang Hong was choked by his "posture" and then became angry and embarrassed: "Everyone can brag, if you really want to make one up, I will...I, Wang Hong, will call you 'Lu' every time I see you from now on!"
"I don't need you to call me anything, and then Zhou Zhe will apologize. Besides, you have to treat all of us to dinner at the restaurant."
Wang Hong snorted coldly: "Who's afraid of who? If you fail, you still have to treat us to a meal."
"No problem." Lu Qingyang agreed readily.
Then he turned his gaze to Zhou Zhe, who was embarrassed and worried, and said in a gentle tone, "Zhou Zhe, are you willing to help me in your spare time? Let's try it together."
Zhou Zhe nodded: "I...I am willing, let's do it together."
Just do it.
Lu Qingyang did not delay. He used Zhou Bo and took Zhou Zhe to start the action.
Relying on the basic principles in the memory space knowledge base and combining them with the radio books found in this era, Lu Qingyang began to draw the exploded diagram and circuit diagram of the TV.
His drawings were extremely detailed, with the parameters and connection methods of each component clearly marked.
Zhou Zhe was a little worried: "Although we know to stay away, but... we don't have any parts? What should we do?"
"Don't worry, I'll take care of these."
Zhou Zhe also knew that Lu Qingyang was very powerful, so he stopped doubting him and decided to trust him.
For a whole week, the two girls sacrificed all their spare time and even stayed up late.
The tool shed was filled with the smell of rosin and solder.
Lu Qingyang was the absolute core brain of the command. He consulted the blueprints and precisely directed Zhou Zhe to perform every operation: cutting the copper clad laminates, drawing the circuits, and using a small amount of etching liquid to make each printed circuit board; carefully soldering each component to ensure there were no cold or incorrect solder joints; installing the deflection coils at a strict angle and distance; and carefully handling the high-voltage parts...
Zhou Zhe's hands were shaking slightly due to the tension and long-term delicate operation, but he was fully focused and carried out every instruction of Lu Qingyang meticulously.
Finally, late at night on the second day, when the last wire was soldered and the last screw was tightened, there was a TV on the simple furniture table.
Zhou Zhe held his breath, his palms were full of sweat.
He watched Lu Qingyang connect a makeshift antenna and then plug the machine into a power source.
A slight buzzing sound came from inside the machine, and the filament of the cathode ray tube began to glow with a faint orange-red light.
Lu Qingyang looked focused. He picked up a small screwdriver and began to carefully adjust several key knobs.
First, there were random snowflakes on the screen, accompanied by a harsh noise.
Zhou Zhe's heart was in his throat.
Lu Qingyang frowned slightly, and his hand movements were extremely subtle.
As he debugged the system, the snowflakes on the screen began to change and the noise gradually subsided.
Suddenly, a blur of color appeared.
Then, the color blocks began to stabilize and condense...
"It's done, it's colorful." Zhou Zhe was so excited that he was incoherent.
"Yeah, I'm done. I'll take it and wait until tomorrow to show that bastard Wang Hong."
…
Wang Hong didn't take Lu Qingyang's boast of "making television" seriously at all.
In his mind, these were just some meaningless harsh words uttered by Lu Qingyang to save face for that country bumpkin Zhou Zhe.
He even used this as a great joke during the breaks for the next few days, and would make sarcastic remarks from time to time.
"Hey, Zhou Zhe, when will you be able to watch that TV in your house? Has Master Lu done anything yet?"
"Lu Qingyang, have you gathered all the parts? Don't end up building a radio that only makes noise! Haha!"
