Chapter 259 The German’s Bad Trouble (Fourth update, please subscribe)
How much do 4,000 electronic real tubes and other corresponding materials cost?
About thirty to forty thousand dollars.
But it was only thirty to forty thousand US dollars that delayed mankind's first electronic computer from 1938 to 46 years.
As early as 1938, Zuse and his friends were already considering assembling a new computer using 2,000 electronic vacuum tubes and other electronic components. When he proposed the idea to some people, it was labeled "fantasy" because electronic vacuum tubes were expensive.
Now, as soon as Chu Ze proposed this idea, it was reported to the Office of the Commissioner.
“Give him everything he needs.”
After learning that Kandra Zuse needed several thousand electron tubes and about 100,000 yuan in testing funds, Li Yian did it straightforwardly Instructions were issued.
Although Kondra Zuse was not on the list provided by Berlin, he was on Li Yi'an's list, or in other words, one of the few German scientists he could think of. There was no way - -He can almost be called the true father of electronic computers.
Unlike his counterparts in the United States, living under the rule of Nazi Germany, he had no way to learn the theoretical basics of computers, nor could he get funding from universities or government agencies. He could only live alone in his bedroom. The long development work began, groping forward in the dark.
His research paid off, from the electromechanical V1 to the V2 using electromagnetic relays, and then to the V3. The V3 invented by Zuse was the computer with the highest level of programming language in the world at that time. Because of this, many people had assumed that if Zuse had not lived in Germany under fascist rule, he might have upgraded the V-type computer series to Electronic computers, the history of world computers will be rewritten.
In fact, before he studied V2, he had already chosen electronic tubes. However, electronic tubes were too expensive for individuals to afford, and officials and enterprises did not realize the role of electronic computers.
Then the tubes became cheap relays.
It can only be said that fate has a way with people!
“Give him the funds and tubes he needs, as well as any other assistance.”
After giving this instruction, Li Yian looked at the report. Although he did not know what kind of changes Chu Ze's arrival would bring to the electronic computer industry, he was certain that he would definitely create Borneo's The first electronic computer. After all, after going through the most difficult time after the war, in 1949, Chu Ze once again reassembled the Z4, still by hand.
Although early electronic computers had been invented in the United States at that time, and the Z4 using relays seemed a bit old-fashioned, the Z4's simple programming and powerful arithmetic unit with exception handling capabilities were still impressive. Z4 was subsequently purchased by ETH Zurich for research in the fields of mathematics and engineering. At this time, the era of electronic computers had truly begun, and the Z4 became the first fully functioning commercial computer in history and the only computer available in continental Europe at the time.
"Is it Z4 or "ENIAC"?"
With this calculation in mind, Li Yian will inevitably have some expectations. After all, he comes from the 21st century and knows well about electronics. How computers changed people's lives.
Because of this, he poached Walter Bratton from Bell Laboratories early and funded the establishment of a laboratory to conduct transistor research, although he was unwilling to leave the United States. But...it doesn't matter, the important thing is transistors and semiconductors!
After all, semiconductors and integrated circuits are the future. As for electronic tubes, let others go down a dark road.
However, the development of transistors does not seem to have made much progress until now.
"Do you want to supervise me?"
This thought just passed by. Although he does not understand technology, Li Yian still knows that sometimes technical matters cannot be rushed. . Especially this groundbreaking technology.
There is no rush.
It doesn't mean you can't do anything. You can't use whips, but you can use candies. The right financial incentives often yield unexpected rewards.
Just as New Year's Day of 2016 was about to come, good news came from Kota Kinabalu - a new single-cylinder diesel engine was successfully developed.
With the stimulus of 10,000 yuan in funding, the research and development team created a new two-stroke single-cylinder diesel engine in just one month.
Although it cannot be said to be a miracle, it can definitely be called rapid progress!
After learning the news, Li Yian rushed over immediately. After all, the two-stroke single-cylinder diesel engine is not only related to agricultural tricycles, but also to a series of small agricultural machinery including small four-wheel tractors and water pumpers. equipment, and even related to the automotive industry in Borneo.
Agricultural three-wheelers are also in the automotive industry.
After arriving at the machinery maintenance shop in Kota Kinabalu, Li Yi'an heard the familiar "boom, boom" sound before he even arrived at the technical office. Even from a distance, he could smell a strong The smell of diesel smoke,
Yes, that’s right, that’s the smell.
When he arrived at the technical department, Li Yian saw a familiar-looking diesel engine running on the test bench. Smoke billows.
"Migong, is this our diesel engine?"
Different from the last time he was called Lao Mi, this time Li Yian changed his name again.
“Yes, the 12-horsepower two-stroke single-cylinder diesel engine was designed to simplify the structure as much as possible according to your requirements. Its number of parts is reduced compared to Deutz’s single-cylinder diesel engine. 25%, the working hours have been reduced by 20%, and the cost...well, it is expected to be reduced by 20%-30%, and there is room for further reduction!”
After taking over the technical parameters from Milian’s hands! , just after a brief look, Li Yian nodded with satisfaction and said.
"Okay, this is the diesel engine we need. How about it? Can it be installed in a car?" I have to say that those German engineers are still very good. They can understand themselves in such a simple time. Their intention is to design such a diesel engine that is not technologically advanced, but is simple and durable, which is enough to prove their ability.
"Sir, we have already conducted 200 hours of test runs. Although we still need to conduct a durability test of no less than 5,000 hours, there is definitely no problem with loading."
The engine designer's answer made Li Yian's smile became even brighter and he turned around and asked.
“Has our body design been completed?”
Perhaps inspired by Chu Ze’s experience of rubbing an electronic computer in his bedroom, there must be nothing rare about rubbing a farm tricycle.
The computer is made out of scratches, and it’s just a stupid, big, black and thick tricycle?
"Sir, by improving your preliminary design, we have completed the basic design of the tricycle."
When it comes to the design of the tricycle, Milian is inevitably a little proud. After all, on the basis of borrowing Li Yian's idea, , he further refined the design.
When the drawings were unfolded, Li Yian was stunned!
“Why is there a carport?”
“Sir, this is taking into account the local rainy climate. Adding a cab carport can avoid the sun and rainforest, and can significantly improve the driving environment! ”
This was barely acceptable, but soon, Li Yian became uneasy.
“In order to improve its driving performance, we use steering wheel steering, which is more comfortable and more efficient for driving than handle steering.”
A steering wheel was actually added, and Li Yian even He was not interested in listening to Milian anymore. All he could see was the complicated steering mechanism.
How much more difficult is this to make!
Don’t you know how good you are!
He actually made a steering wheel!
This is a repair shop!
Not a car manufacturer!
Don’t you know that this will increase the difficulty of manufacturing a lot?
Now they don't even notice this. Even so proud of everything.
At this moment, Li Yian felt that Chu Ze was a genius. He could make very complicated things very simple. Use cheap relays to realize the calculation function of expensive tube computers.
But this group of people complicates simple things.
At this moment he seemed to understand why all three virtues failed.
These are the guys who strive for perfection and complicate simple things. They always want the best from all aspects of engineering, but they ignore the most important point-real needs.
What are the realistic needs?
Definitely not a complicated thing, but simple and easy to make.
This was true during the war, and it is true now.
The result was good for them. Instead of learning their lesson, they were complacent here.
However, Milian obviously did not notice Boss Li's changing expression. Instead, he pointed at the drawings proudly and continued to introduce their improvements.
“In order to increase the transmission efficiency of the engine, we changed the belt drive to a transmission shaft drive. Through calculation, the use of a transmission shaft can increase...”
Before he could finish speaking, he saw Li Yian speaking directly with a cold face.
"Is it my original design? Where is my original design?"
The fundamental reason why he was so angry was that the original design was so simple. It was made so complicated by these people that it could even be said to have completely subverted his original design.
“Redesign it for me!”
