After negotiating the purchase of 10 sewing machines, Li Guocheng paid attention to the damaged sewing machines in the back warehouse.

"Old world, you have also seen that now these 10 units look shiny, and the inside is seriously worn. In order to facilitate the replacement of parts, can you provide some broken sewing machines of the same model? ”

The boss smiled, "Okay, you give 200 Hong Kong dollars for one."

Li Guocheng thought about it, "Okay, but I have to choose it myself."

"No problem".

The boss led Li Guocheng to the back warehouse and pointed to a corner, "It's all there."

Li Guocheng came to the damaged sewing machines that were piled up on the shelves in chaos, and through his telekinesis, he picked out some sewing machines of the same model that had no problems with the main structure, but some delicate parts were damaged inside.

"That's all there are seven," Li Guocheng pointed to the seven sewing machines he had selected and stacked on the ground.

"Good eye, these are the best of them."

Li Guocheng looked at him funny, he didn't have any embarrassment, just smiled.

17 sewing machines, a total of 4,900 Hong Kong dollars, pay half of it first, the boss helps to send it to the factory, and then pay the other half.

By the time all the sewing machines were moved to the factory to settle the final payment, it was already more than 2 o'clock in the afternoon.

Li Guocheng used his telekinesis to re-scan all 17 sewing machines to observe wear and tear, and soon, Li Guocheng knew how to repair them, and the idea was very simple, remanufacturing.

Now there is a lack of materials on hand, so I can only wait for Jin Yang to find Tian Xingguo to see how he procures materials.

Now that there is nothing to do, Li Guocheng put all the sewing machines into the secret realm and returned to the rental house.

Taking out a blank sheet of paper, Li Guocheng began to draft patents for calculators and electronic watches.

In 1888, the Austrian botanist F. Reinitz discovered liquid crystals for the first time. In 1963, RCA's Willy Ames discovered that when liquid crystals are electrically stimulated, their light transmission patterns change. Liquid crystal display technology first appeared in 1968.

The above information is obtained from the Kowloon Public Library. The Kowloon Public Library, a 12-storey Kowloon Public Library, was opened in August 1965 at the Kowloon Public Library on the second floor of Kwun Wah Garden, Waterloo Road, and was the first public library established by the Urban Council in Kowloon.

The biggest disadvantage of the current liquid crystal is that it works at high temperatures, and it can be seen from some information that we have a lot of attempts to work at room temperature, relying on these experiences, Li Guocheng is confident to design an LCD panel that works at room temperature.

But now this is not in a hurry, Li Guocheng first applied for a patent for the application of liquid crystal. After a few years, liquid crystal technology began to be applied, and the patent for liquid crystal display was also applied.

The more Li Guocheng thought about it, the more excited he became, isn't it, he doesn't have to do anything now, just concentrate on writing patents, and he can become the richest man in the world by relying on patent licensing in the future.

After a while, Li Guocheng smiled. I know that if I really dare to do this, and I will launch a bunch of patents without any technical foundation, I don't have to think about it, and it is estimated that it will soon become a research specimen on the experimental table.

Readjusting his mentality, Li Guocheng completed the writing of two patents before Azhi made dinner, he read it again, and he also felt a little frustrated, and the coverage was too large.

Reconsider, such a large coverage, the first is that the patent fee is too high, and the second is that it has to leave a way for others to live. Things should not be done too far to avoid arousing public anger.

Soon after the meal, Uncle Wang and Brother Hua came to the rental house together.

"Aaron, the budget is out, the contractor is 28,000 Hong Kong dollars, and the down payment is 19,600"

Li Guocheng took the budget sheet, carefully checked the expenses, focused on the dormitory, and felt that the materials were real, and there was no problem in other aspects.

took out the checkbook, wrote a check for 19,600, handed it to Uncle Wang, and at the same time handed him the key to the factory, and made an appointment to close the house in a month and a half.

Li Guocheng first went to the law firm to sign an entrustment agreement for the patent application for electronic watches and calculators. Then go to Golden Sun to find Tian Xingguo and take away some of the purchased materials.

In the following time, he occasionally went to Far Eastern Securities to take a look around and feel the thrill of rising stocks. During the day, I went to the library to read books and look up materials, and at night I made gyroscopes by hand in the house.

After five failures, Li Guocheng had to send the hand-carved parts into the secret realm, and dust and assemble them step by step. When he got the final finished product, held it in the palm of his hand, and turned it gently, Li Guocheng knew that he had succeeded.

The angular velocity is extracted using the electromagnetic principle and is actively output using three sets of differential pulse signals. The purpose of choosing a differential signal is to improve the anti-interference ability.

After thinking about the interface of the flight control computer, there is a lack of one way and cannot be connected directly. I had to redesign a dedicated CPU with multiple interfaces. Considering the cost and the manufacturing capacity of the lab, the core is still KT32F100 based.

On the basis of the original one, it has been added to 6 UART interfaces, 5 SPI interfaces, and 1 I2C interface.

In order to ensure the success of the design the first time, Li Guocheng had to carry out repeated zoom-in inspections and simulations.

The time soon came to the date of delivery, Li Guocheng put all the items in the rental house into the secret realm, left a note for Ah Zhi, and took the bus to the factory.

As soon as you enter the courtyard gate, you will feel that your eyes are bright, and the overall feeling is that it has been renovated, and all the exterior walls of the house have been repaired and cleaned. The dormitory on the east side is the same as the drawings.

Entering the room, it is cleaned, and the running water and sewerage pipes are connected to the municipal facilities.

Each room has 3 bunk beds, a total of 6 beds, and there is a row of wardrobes near the door and directly opposite the shelf bed. The basic living conditions are in place.

These things in the dormitory, Li Guo wanted to buy them in the market. After Uncle Wang found out, he directly brought a carpenter master from the Kowloon Walled City, 10,000 Hong Kong dollars, together with the seats in the canteen and 20 sets of sewing machine log bases.

The master carpenter took his family and apprentices to live directly in the warehouse, worked overtime, and finally completed the fabrication of all the objects before handing over the house.

Li Guocheng was very satisfied and happily settled the final payment.

"Boss Cheng, I know from Brother Hua that you are looking for female workers here, and my brother is cheeky to ask you for something."

Li Guocheng knew in his heart that in the past more than a month of cooperation, Li Guocheng has already believed in his character very much, "Uncle Wang, you are polite, you can speak if you have something, don't say anything you want or not."

"My second girl is 17 years old this year, and she has been doing some sewing and mending work with her mother at home, and she can endure hardships, see if you can give her a job."

"Okay, I believe in your character, take it. This is Ling's son Xiaoxuan, right, looking less than 15 years old, right? ”

"Well, it'll be 15 in two months", Uncle Wang seemed to hear something, and his face was eager.

"After a few contacts, Xiao Xuan is a child who is willing to endure hardships, in addition to his lack of strength, he also does a good job. It's not a way out to follow you to do this, I'm looking for your assistant, you see? ”

"Great, Xiao Xuan, quickly kowtow to Uncle Long", Uncle Wang was overjoyed, and asked him to kowtow to Li Guocheng after pulling his son.
