After dealing with these important things, Zhang Wenkai didn't know what to do, and felt that he had suddenly become an idler.

The construction of Dongzheng Company was not handed over to a construction company, but three construction companies were found to start construction at the same time, which not only was the speed fast, but also the construction quality and speed of the three companies could be comprehensively compared.

As for when it will be completed, Zhang Wenkai believes that it will be very fast, if it is slow and leisurely, the construction party will not get the money, after all, their own requirements are speed and quality.

Dongzheng Company's problem is only a matter of time.

As for the smart housekeeper, it has begun to make a profit, although it is not a lot, only a few hundred million, but this is just the beginning, after all, people are not very suitable for the smart housekeeper, and when people can't do without it, at that time, the money will continue to enter their pockets.

Besides, at present, the smart housekeeper is not very comprehensive, and it needs to be improved in many places, as far as the voice package is concerned, it is currently limited to domestic second-tier stars, and only when the business expands can the situation of the smart housekeeper be opened, these things are handed over to Zhao Tianzhi to implement, and there is no need to worry about it, as long as you grasp the general direction.

As for the growth line of mobile phone lithium batteries and special ceramics, they can only be mothballed, and who has not yet built Dongzheng Company, so these plans cannot be implemented, and graphene batteries cannot be produced.

After things were straightened out one by one, Zhang Wenkai found that he had nothing to do, rubbed his eyebrows, he had almost learned the alien code, even if he was busy, he would take time out every day to learn the knowledge of the alien code.

Even if Zhang Wenkai is asked to make a wireless charger independently, Zhang Wenkai can complete it.

Now that the equipment for developing holographic projection is in place, it is time to develop holographic projection technology, Zhang Wenkai thought to himself.

At present, Zhang Wenkai's office location has been moved from the seventh floor to the eighth floor, and the original office room on the seventh floor has a server for intelligent housekeepers, Zhang Wenkai directly asked Zhou Yuya to vacate a room on the eighth floor and changed it into Zhang Wenkai's temporary studio, after all, the development of holographic projection also requires the placement of some equipment.

All the equipment and materials have been shipped to the newly opened studio, and Zhang Wenkai began to develop the holographic projection technology.

Holographic projection technology has been put into the market in various countries, and the concert of "Hatsune" uses holographic projection technology, but it has not yet entered a wide range of civilian use.

And Zhang Wenkai developed the holographic projection technology given by Xiao Na, which is somewhat different from the technology on the earth, but in Zhang Wenkai's opinion, the difference is not very big.

It is not difficult to manufacture a holographic projection device on the earth, and its principle is already a recognized technology, so Zhang Wenkai chose to buy a complete holographic projection device directly.

Although it is not very useful and can only be used for research, Zhang Wenkai feels that it is necessary to study it carefully.

Normally, Zhang Wenkai only needs to make holographic projection equipment step by step according to Xiao Na's requirements, but Zhang Wenkai has his own ideas in his heart.

Take the wireless charger as an example, after Zhang Wenkai's study, even if you don't have the help of Cortana, you can still make money by wireless charging, if you don't learn anything, just blindly rely on Cortana, in case there is no Cortana, wouldn't you have nothing, and you must have a long-term vision.

So Zhang Wenkai has always insisted on learning it by himself, then communicating with Xiao Na, and finally making a product.

Opened the holographic projection equipment that had been assembled, Zhang Wenkan repeatedly experimented with the function of holographic projection, and Zhang Wenkai was very surprised by the use of holographic projection, this thing is too amazing!

The three-dimensional image floating in the air looked like a real object, and Zhang Wenkai couldn't help but reach out and touch it, wondering if it was real.

Although the holographic projection technology is very clear, it feels a lot worse than Cortana's projection, is it because of intelligence? Zhang Wenkai didn't know either.

After in-depth research, Zhang Wenkai has also figured out the relevant technical information of holographic projection, and took out the relevant information of laser beam projection technology given by Xiao Na, and began to study it, the more in-depth the research, the more surprised Zhang Wenkai became, this technology is not at all understandable to earthlings, this technology can actually control the length of laser propagation.

We all know that light travels along rays, which means that it can propagate infinitely, as long as it is not reflected or refracted and can continue to propagate, so how does this technology control the length of light? Zhang Wenkai didn't understand that this technology was completely beyond the scope of Zhang Wenkai's comprehension.

encountered a principle that he didn't understand at all, Zhang Wenkai had no choice but to call Xiao Na out, wouldn't he have to learn it!

"Cortana, this controls the length of the laser propagation, what the hell is this principle?"

Xiao Na's projection phenomenon came out, and when she heard Zhang Wenkai's question, she also fell silent first.

In fact, as an artificial intelligence, Xiao Na also has her own ideas, hearing Zhang Wenkai's question, Xiao Na didn't know how to explain for a while, the explanation is too complicated for you to understand, the explanation is too simple, you can't understand it even more, to put it bluntly, this technology has been out of Zhang Wenkai's cognition, how to explain it is difficult for the other party to understand.

After about a minute, Cortana finally spoke: "Sir, there are many factors involved, the density of the air, the floating particles in the air, the intensity of the laser, the intelligent dimming system, etc., each of which is the factor that contributes to the realization of this technology, and Cortana can only explain so much for you." ”

Hearing Xiao Na's explanation, although it sounded plausible, Zhang Wenkai roughly understood the meaning, this technology is a grasp of the overall environment, not just a chip can do it, there is too much knowledge involved, since I don't understand it for the time being, let's learn it slowly, and I will always understand it in the future.

I took out some of the ordered materials, and according to the drawings, I made them.

Of course, the experimental record is necessary, because of the existence of Cortana, Zhang Wenkai thought of a perfect way, you can record the video while not affecting the communication with Cortana, that is, after communicating with Cortana first, then start recording, then pause, communicate with Cortana again, and then record, although it is a little troublesome, but it can save a lot of things, so that the video is more real and more effective.

The first few steps are very simple, and there is no difficulty, even so, Zhang Wenkai still encountered a lot of difficulties, the line is connected wrong, or there is a problem with the chip welding, anyway, there are a lot of mistakes, and these errors are also recorded in the camera one by one.

Today's work can only go here, Zhang Wenkai turned off the camera, but what Zhang Wenkai didn't expect was that he was busy all day today, and he didn't sit out of the simplest light emitter, and he was a little discouraged emotionally, but the next moment, Zhang Wenkai was full of energy, no matter how he had to succeed, maybe this is the quality of Zhang Wenkai's success in the future, insist!

In the next large period of time,Zhang Wenkai completely put all his energy into the research and development of holographic projection,Each component is completed one by one,Each electronic module is carefully spliced one by one,The completion of these components alone took Zhang Wenkai half a month,Zhang Wenkai seems to be like a closed person in this half a month,The door is not out,The second door is not stepped,Just the smell of various welding and components,Zhang Wenkai wants to vomit。

Today is the twenty-eighth day of research and development of holographic projectors,At this time, Zhang Wenkai looked at the palm-sized holographic projector in front of him with a swiped beard,Zhang Wenkai seemed a little excited,First stretched out his hand to turn off the camera,Then called out Xiao Na,Said:"Xiao Na,How to get the chip code of this holographic projector。 ”

Zhang Wenkai's question attracted Xiao Na, who was walking away from the circle, and said to Zhang Wenkai: "Sir, do you need Xiao Na to give you ready-made code, or do you write it yourself, sir." ”

Xiao Na's words surprised Zhang Wenkai a little, has Xiao Na started to ask for her opinion? Or did Cortana guess what I was thinking? Zhang Wenkai shook his head.

Holding the holographic projector, he replied to Cortana's words and said, "I wrote it myself, but I need Cortana to give me some guidance."

"Yes, sir." After Xiao Na answered, she began to guide Zhang Wenkai to write the chip code.

But knocking and knocking, Zhang Wenkai felt that something was wrong, because in the past, whether it was a wireless charger or a smart housekeeper, there was no complicated code composition, but the code of this holographic projector is different, its code is too complicated, so complicated that Zhang Wenkai was already dizzy, and couldn't help asking: "Xiao Na, why is this so complicated?" ”

Cortana replied, "Sir, the intelligent dimming system is the most core system, and it governs the operation of all these electronic modules, so it is the most complex. ”

Zhang Wenkai clicked and continued to type on the code, after some hard work, it finally became the writing of all the code, and then directly written into the chip through the computer, Zhang Wenkai took the palm-sized holographic projector, first turned on the camera, and then began to check the effect of the holographic projector, and input the pre-edited impact into the projection one.

I saw a few rays of light coming out of the holographic projector, and then there were more and more lights, one long and one short, flickering non-stop, but slowly the light finally focused together, clearly showing the same projection as Xiao Na, because the image prepared by Zhang Wenkai is Xiao Na's image.

Looking at the 3D image projected by the holographic projector, I made a comparison with Xiao Na, there are still many flaws in the details, but although there are flaws, Zhang Wenkai is still very excited, after all, he made it himself.
