Reborn in 2005, starting with repairing mobile phones

It was already dark when the car stopped downstairs at the "International Science and Technology Building".

Lin Dong opened the car door and looked up at the building.

His company is on the top floor of the 52nd floor.

The lights on that floor were still on.

He got into the elevator.

The elevator doors opened, facing the company's glass doors.

The door was unlocked, and the sounds of typing and occasional discussions could be heard from inside.

Lin Dong pushed open the door and went in.

In the office area, the three people were each engrossed in their own work.

Zhang Mingyuan sat in the corner, frowning as he stared at the computer screen.

Zhou Chengyu was opposite him, holding a stack of printing paper in his hand, scribbling on it with a pen.

Su Xiaowen stood by the window, with a whole wall of sketches in front of her.

No one noticed him coming in.

Lin Dong stood at the door and looked for a second.

Then he spoke.

"They're all here."

All three people looked up at the same time.

Zhang Mingyuan was the first to stand up.

"President Lin!"

Zhou Chengyu put down his pen.

Su Xiaowen turned around.

Lin Dong went inside.

"sit."

......

He walked over to Zhang Mingyuan first.

On Zhang Mingyuan's computer screen were densely packed circuit diagrams.

Lin Dong glanced at it and immediately saw where the problem lay.

"Where is it stuck?"

Zhang Mingyuan paused for a moment, then sighed.

"Mr. Lin, this power management module..."

He pointed to a section of the screen, "I tried three different solutions, but I couldn't reduce the ripple. The requirement is below 10mV, and I only managed to get as low as 13mV. I just couldn't get it any lower."

Lin Dong stared at the circuit for three seconds.

"here."

He pointed to the location of one of the capacitors, "You're using a regular aluminum electrolytic capacitor. Replace it with a tantalum capacitor. Change the packaging, and this space will be able to accommodate it."

Zhang Mingyuan was stunned for a moment.

"Tantalum capacitors? But the cost..."

Lin Dong glanced at him.

Zhang Mingyuan swallowed the rest of his sentence.

"clear."

He nodded. "I'll try it right away."

Lin Dong patted him on the shoulder.

"Tell me the results after you try it."

......

He walked over to Zhou Chengyu's side.

The stack of printed papers in front of Zhou Chengyu was filled with densely packed algorithm code.

His brows were furrowed deeply. When he saw Lin Dong approaching, he opened his mouth, then closed it again.

Lin Dong looked at him.

"Speak."

Zhou Chengyu sighed.

"Mr. Lin, we've encountered a bottleneck with the touch algorithm..."

He pointed to a line of logic on the paper, "When tracking multiple points, the trajectories of two points may occasionally swap. The probability is low, but it does happen. I've adjusted it three times, but I haven't found the reason."

Lin Dong took the stack of papers and looked at them for a few seconds.

"Prediction step size of Kalman filtering,"

He said, "Are you setting a fixed value now?"

Zhou Chengyu was stunned for a moment.

"A fixed value for..."

Lin Dong returned the paper to him.

"Change it to be dynamic. It should adapt to the speed of finger movement."

Zhou Chengyu stood there, stunned.

Before he could react, Lin Dong continued, "Run the simulation first, and contact me if you encounter any problems."

Zhou Chengyu snapped out of his daze, his eyes lighting up.

"it is good."

......

Finally, it's Su Xiaowen.

She stood in front of that wall, which was covered with sketches.

Lin Dong walked over and stood next to her.

"How is it?"

Su Xiaowen did not turn around.

"I drew more than a hundred versions."

She said, "I'm not satisfied with any of them."

Lin Dong looked at her.

"What are you not satisfied with?"

Su Xiaowen turned around and looked at him.

"The feeling you're describing,"

She said, "I can't draw it."

Lin Dong nodded.

He took something out of his pocket and placed it on the table in front of her.

A folded piece of paper.

Su Xiaowen opened it.

Then she froze.

That was a design drawing.

The lines were simple, the proportions precise, and every detail was clearly marked. It was completely different from the sketches she had seen before.

She looked up at Lin Dong.

"This is……"

Lin Dong looked at her.

"Do it this way," he said. "Any problems?"

Su Xiaowen shook her head.

"no."

Lin Dong nodded and turned to walk towards the conference room.

He took two steps and then stopped.

"A meeting will be held in the conference room in half an hour."

He said, "Let's synchronize the progress."

All three responded at the same time.

"it is good."

......

Lin Dong walked into the conference room and sat down at the head of the table.

The city lights outside the window are bright.

He leaned back in his chair and closed his eyes.

Let them go on their own.

The issues we just discussed included Zhang Mingyuan's power supply ripple, Zhou Chengyu's algorithm bottleneck, and Su Xiaowen's design stagnation.

He knew the answer to every question. He could simply tell them that it would be resolved in ten minutes.

But that's not what he wanted.

What he wants is not for them to "obey," but for them to "think."

Zhang Mingyuan just said, "I tried three options."

Zhou Chengyu said, "We revised it three times."

Su Xiaowen said, "I drew more than a hundred versions."

They have already gone as far as they can, and are just one last step away.

He only needs to give it a push.

After pushing them, let them take the next step on their own.

He opened his eyes and looked out the window.

These people are all geniuses.

But even geniuses need to train their minds.

This is exactly what he wanted.

He pointed out the direction from the front, and they paved the way from behind.

If you go the wrong way, he will point it out again.

If they've taken the right path, they'll know how to proceed next time.

A team trained in this way is not just composed of people who can execute orders.

He is someone who can stand on his own.

He leaned back in his chair, a slight smile playing on his lips.

okay.

It's time for the meeting.

After half an hour.

Footsteps could be heard outside the meeting room.

The door was pushed open.

Zhang Mingyuan was the first to come in, holding a stack of circuit diagrams in his hand, his expression somewhat complicated.

Zhou Chengyu followed behind, still clutching the stack of printing papers in his hand, the edges of which were creased from his grip.

He walked behind Zhang Mingyuan, head down, as if he was thinking about something.

Su Xiaowen was the last to come in.

She held the design drawing Lin Dong had given her in her hand, looked at it several times, and then looked up at Lin Dong again.

The three people sat down.

Uncle Cai and Zheng Hao also came in and sat near the door.

There was silence for a few seconds.

Zhang Mingyuan spoke first.

"President Lin."

Lin Dong looked at him.

Zhang Mingyuan paused.

"That tantalum capacitor..."

He took a deep breath. "After switching on, the ripple dropped to 8mV."

Lin Dong nodded.

"Um."

Zhang Mingyuan looked at him, opened his mouth as if to say something, but then swallowed it back.

Zhou Chengyu spoke up from the side.

"Mr. Lin, that dynamic step size solution..."

He paused for a moment, then continued, "I ran a simulation, and the trajectory swapping problem is solved."

Lin Dong nodded again.

"Um."

Zhou Chengyu looked at him with a complicated expression.

Su Xiaowen didn't say anything.

She just looked at the design drawing in her hand, then at Lin Dong, and then at the drawing again.

Lin Dong waited for three seconds.

"Have you finished speaking?"

The three people remained silent.

Lin Dong leaned back in his chair.

"Now that you've finished speaking, I'd like to say a few words."

Uncle Cai and Zheng Hao sat up straight.

Lin Dong spoke.

"This trip to San Francisco was somewhat fruitful."

He looked at the people present.

First, the materials.

"A batch of high-grade aerospace aluminum is already on its way and will arrive at the port within two weeks."

He paused for a moment, then said, "From now on, when you're making the structure and the outer shell, you won't have to worry about materials. You'll have as much as you need."

Zhang Mingyuan was stunned for a moment.

Su Xiaowen's eyes lit up.

Lin Dong continued, "Secondly, funding."

He glanced at Uncle Cai.

Uncle Cai nodded.

Lin Dong withdrew his gaze.

"Once this batch of materials is sold, the profit will more than double. Once the money is in your account, you won't need to be so stingy with your R&D anymore."
