The engine modification work was successfully completed. Lin Zhiyue breathed a sigh of relief, his face filled with the joy of success.
She gently stroked the engine that she had modified and made brand new, feeling a sense of accomplishment.
However, after a brief moment of excitement, her thoughts drifted elsewhere.
Lin Zhiyue knew very well that in the 1970s, transportation infrastructure was far less developed than in later generations, road signs were scarce, and maps were not accurate or detailed enough. For people who were not familiar with the road conditions, driving was like a difficult adventure and it was easy to get lost.
No matter how much the performance of a vehicle improves, it will be useless if the driver cannot find the destination accurately.
Thinking of this, a bold idea came into her mind - to install a navigation system in the car.
In the 1970s, when technological development was still at a relatively backward stage, mentioning navigation technology was almost like a pipe dream.
At that time, people relied on simple and rough maps when traveling. If they encountered unfamiliar and complicated routes, they would be completely in the dark and helpless.
Who is Kelin Zhiyue?
She is an all-round scientist who has come through the apocalypse.
In the harsh environment of the end of the world with dangers lurking everywhere and resources extremely scarce, she relied on her outstanding wisdom and super hands-on ability to not only survive the tests of life and death time and time again, but also successfully developed many scientific and technological achievements that could change the survival pattern of the end of the world.
From protective equipment to resist zombie attacks, to devices that use limited resources to create efficient energy, to the establishment of simple but practical communication networks, each of her inventions brings new hope to survivors of the apocalypse.
For her, adding a navigation system to the vehicle was not an easy task, but it was by no means an insurmountable obstacle.
In her view, this is just another challenging technical challenge.
As soon as the thought flashed through her mind, she took action immediately.
With a firm gaze and an unquestionable confidence, she strode towards the work area filled with various tools and parts, and quickly and skillfully picked out the materials that might be used.
Lin Zhiyue knows very well that chips and signals are the core key to the navigation system. They are like the "brain" and "nerves" of the navigation system, directly determining whether the entire system can operate normally.
So she quickly cleared out a tidy area on the workbench that was piled with tools and parts, and neatly arranged the chips and signal-related materials collected from various places, ready to start in-depth research.
She first picked up the chip that was dismantled from an obsolete electronic device abroad. The chip was shining with metallic luster under the light. Although it looked a little old, in Lin Zhiyue's eyes, it contained infinite possibilities.
She carefully placed the chip under a high-precision microscope, stared at the eyepiece, and carefully observed the circuit structure inside the chip.
She could see every tiny line and every tiny transistor.
As she observed, she recorded the chip's parameters, circuit layout, and possible problems in detail in her notebook.
After careful observation, Lin Zhiyue found that although the signal processing capability of this chip could basically meet the initial needs of the navigation system, it still lacked signal accuracy and stability.
In order to solve this problem, she looked into everything from basic circuit principles to cutting-edge chip optimization technology.
Lin Zhiyue calmed himself down and focused all his attention on the chip in front of him.
She concentrated her mental power to make the intricate circuits inside the chip appear clearly, with every tiny line visible in detail, like a mysterious and sophisticated maze.
She picked up a tiny welding needle as thin as a hair, which carried all her expectations and concentration.
Her hands were as steady as those of an experienced craftsman, and with the help of her mental strength, she slowly approached the chip.
The soldering needle touches the target line precisely and begins to make minor adjustments to it.
During the welding process, any carelessness would result in all previous efforts being wasted, so Lin Zhiyue didn't even dare to breathe.
She carefully melted the solder so that it adhered evenly to the wire, while adjusting the direction and connection method of the wire.
During each operation, she carefully observes the changes in the circuit to ensure that the solder joints are firm and the circuit layout is reasonable.
As time went by, sweat quietly climbed up her forehead, but she was unaware of it.
His eyes were fixed on the chip under the microscope, and his hands operated the tools mechanically and precisely.
When she encounters a place where crossed lines affect signal transmission, she will cleverly use insulating materials to separate the lines, and then re-weld the connections to ensure smooth signal transmission.
After several long and agonizing hours, Lin Zhiyue finally completed the transformation of the chip's key circuits.
She let out a long sigh, put down the tools in her hands, and looked at the modified chip with a sense of accomplishment, looking forward to it bringing surprises in subsequent tests.
After completing the transformation of the key circuits of the chip, Lin Zhiyue did not slack off at all. After a short rest, he began to prepare for the preliminary testing of the chip.
She carefully installed the modified chip on a circuit board specially built for testing, connected various complex lines, and checked each interface repeatedly to ensure the connection was correct.
Everything was ready. Lin Zhiyue took a deep breath and pressed the start button of the testing equipment.
In an instant, the indicator light on the device began to flash and various data appeared on the screen.
She stared at the screen, her eyes full of nervousness and anticipation.
Initially, data showed that the chip was operating stably, but when a simulated navigation signal was input, the signal fluctuations were still beyond the expected range.
Lin Zhiyue frowned. She understood that although the line reconstruction had achieved certain results, there were still some problems that needed to be solved.
She quickly entered the analysis state, carefully compared the data before and after the transformation, and reviewed the relevant information again, not missing any factors that might affect the signal.
After some in-depth research, she found that some of the capacitor parameters inside the chip were not ideally compatible with the new circuit, which caused unnecessary interference in the signal during transmission.
After finding the root cause of the problem, Lin Zhiyue took immediate action.
She rummaged through the parts box to find a capacitor that met the requirements and prepared to make a secondary modification to the chip.
This time, her operation was more skillful and cautious.
When replacing capacitors, she not only has to ensure that the new capacitors are installed in the exact position, but also has to be careful to avoid causing any damage to the already modified circuits.
After another round of intense operations, the second transformation was completed.
Lin Zhiyue conducted another test, and when she saw stable and accurate navigation signal data displayed on the screen, a bright smile finally broke out on her face.
This time, the signal fluctuation was controlled within an extremely small range, fully meeting the requirements of the navigation system.
