Siheyuan: Starting from a fitter

Chapter 190 Gyroscope design completed
After negotiating the purchase of 10 sewing machines, Li Guocheng paid attention to the damaged sewing machines in the warehouse behind.

"Lao Shi, you have also seen that these 10 machines look bright but are severely worn inside. In order to facilitate the replacement of parts, do you think you can provide some broken sewing machines of the same model?"

The boss chuckled and said, "Okay, you can pay 200 Hong Kong dollars for one unit."

Li Guocheng thought about it and said, "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 piled chaotically on the shelves. Through his mind, he picked out some sewing machines of the same model that had no problem with the main structure but had some delicate internal parts damaged.

"These are the seven." Li Guocheng pointed to the seven sewing machines he had selected and stacked on the ground.

"Good vision, these are the best among them."

Li Guocheng looked at him funny. He didn't have any embarrassment and just smiled.

17 sewing machines cost a total of 4900 Hong Kong dollars. I paid half of them first, and the boss helped deliver them to the factory and then paid the other half.

By the time all the sewing machines were moved to the factory and the final payment was settled, it was already past 2 p.m.

Li Guocheng used his telekinesis to rescan all 17 sewing machines to observe the wear and damage. Soon, Li Guocheng knew how to repair them. The idea was very simple: re-manufacture.

There is a lack of materials on hand now, so we can only wait until Jin Taiyang finds Tian Xingguo to see how he goes about purchasing materials.

With nothing to do now, Li Guocheng put all the sewing machines into the secret place and returned to the rental house.

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

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

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

The biggest shortcoming of current liquid crystals is that they work at high temperatures. It can be seen from some data that there have been many attempts to work at room temperature. Relying on these experiences, Li Guocheng is confident in designing an LCD panel that works at room temperature.

But there is no rush now, Li Guocheng first applied for a patent for liquid crystal applications.After a few years, when liquid crystal technology starts to be applied, the patent for liquid crystal displays will also be applied for.

The more Li Guocheng thought about it, the more excited he became. Isn't it right? Now he doesn't have to do anything, just concentrate on writing patents. In the future, he can become the world's richest man by relying on patent authorization.

After a while, Li Guocheng smiled.I know that if I really dare to do this and launch a bunch of patents without any technical foundation, I don’t have to think about it. It will probably become a research specimen on the laboratory table very quickly.

After re-adjusting his mentality, Li Guocheng finished writing two patents before Azhi made dinner. He read it again and felt that it was a bit crazy and the coverage was too great.

After reconsideration, for such a large coverage, firstly, the patent fee is too high, and secondly, there must be a way for others to survive.Don't do anything too extreme to avoid causing public outrage.

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

"Aaron, the budget is out, the labor and materials are contracted, the total is 28000 Hong Kong dollars, and the down payment is 19600."

Li Guocheng took the budget sheet and carefully checked the various expenses, focusing on the dormitory. He felt that the materials used were solid and there were no problems in other aspects.

He took out his checkbook, wrote a check for 19600, and handed it to Uncle Wang. He also handed him the factory key and made an appointment to take possession of the house in one and a half months.

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

In the following time, he would occasionally visit Far East Securities to feel the pleasure brought by rising stocks.During the day, I went to the library to read and check information, and at night, I made handmade gyroscopes in the house.

After failing 5 times, Li Guocheng had to send the hand-carved parts to the secret place, and dedust and assemble them step by step.When he got the final product, held it in the palm of his hand, and turned it gently, Li Guocheng knew he had succeeded.

The extraction of angular velocity uses electromagnetic principles and uses three sets of differential pulse signals to actively output.Only choose the differential signal, the purpose is to improve the anti-interference ability.

After thinking about the interface of the flight control computer, I found that there is one missing link and cannot be connected directly.We had to redesign a multi-interface dedicated CPU.Considering the cost and laboratory manufacturing capabilities, the core is still based on KT32F100.

On the original basis, 6 UART interfaces, 5 SPI interfaces, and 1 I2C interface have been added.

In order to ensure the design was successful the first time, Li Guocheng had to conduct repeated amplification inspections and simulations.

The handover date soon came. Li Guocheng put all the items in the rental house into the secret place, left a note for Azhi, and took the bus to the factory.

As soon as you enter the courtyard, you will feel bright. The overall feeling is that it has been renovated. All the exterior walls of the houses have been repaired and cleaned.The dormitory on the east side is exactly the same as the drawing.

Entering the room, it was clean and the tap water and sewage pipes were connected to municipal facilities.

Each room has 3 bunk beds, a total of 6 beds. There is a row of wardrobes near the door and opposite the canopy bed.Basic living conditions are already in place.

Li Guochen had always wanted to buy these things for the dormitory in the market.After Uncle Wang found out, he directly hired a carpenter from Kowloon Walled City and paid 10000 Hong Kong dollars to customize the canteen seats and 20 sets of log bases for sewing machines.

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

Li Guocheng was very satisfied and settled the balance happily.

"Boss Cheng, I know from Brother Hua that you are looking for female workers here. I have the audacity to ask you a favor."

Li Guocheng knew in his heart that after more than a month of cooperation, Li Guocheng had already trusted his character very much, "Uncle Wang, you are polite, just say what you want, and don't ask for anything."

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

"Okay, I believe in your character, so I'll accept it. This is your son, Xiaoxuan. I guess he's under 15, right?"

"Well, I'll be 15 in two months." Uncle Wang seemed to hear something, his face was full of enthusiasm.

"After a few encounters, Xiaoxuan is a child who is willing to endure hardships. Apart from his lack of strength, he can also do a good job. It is not a way out to follow you to do these things. I am looking for your assistant, do you think?"

"That's great, Xiaoxuan, please kowtow to your Uncle Long." Uncle Wang was overjoyed. He took his son and asked him to kowtow to Li Guocheng.
