Zhang Wenkai fired the company's squid in a dashing manner, but he did not go back to the rental house, but went directly to the largest electronic goods market in Jingbei City according to Xiao Na's request.

"Sir, we need to buy a large number of electronic components and chips, which we must use to make wireless chargers" Cortana's voice sounded in the Bluetooth headset.

"If it's just a component, it's okay to buy, but it's a little troublesome for the chip, we can only buy back the electronic products, go back and dismantle it ourselves, and that's the only way" Zhang Wenkai was a little helpless, he really didn't know where to sell the supplies he needed.

"Yes, sir," Cortana said.

Zhang Wenkai wandered around the mall for more than an hour, and finally bought a few components and chips needed for electronic products according to Xiao Na's request, and hurried back to the rental house by bus.

Looking at the messy electronic devices in front of him, with his professional knowledge of electronic information technology, he couldn't think of how to get them, so it could be said that he had no idea at all, and he didn't understand the use of these things that Xiao Na asked to buy back.

Completely out of thought, Zhang Wenkai reached out and took out Cortana from his pocket in his clothes, put it on the table, and Cortana's holographic projection immediately appeared.

"Cortana, what should we do" Zhang Wenkai had a feeling of helplessness.

Xiao Na's projection showed a very serious expression, explaining the technical principles of the wireless charger and the important problems to be paid attention to for Zhang Wenkai.

"After understanding, the earth's wireless charging technology is commonly used in a technology called electrical coupling, his biggest disadvantage is the need for close charging, so it is not a perfect wireless charging technology framework concept, although the earth has appeared effective distance of about two meters resonance induction technology, but it is not suitable for civilian use."

Well, it's really enough to be chicken, it takes so much tightness, the effective distance is only two meters, what's the difference with wires, and even wires are much farther than this resonant technology, I don't know what the difference will be in Cortana's wireless charging technology? Zhang Wenkai asked curiously: "Then what is the better technology to achieve it?"

"Yes, sir, wireless charging technology was developed very early on the home planet, and his framework concept is somewhat similar to resonant induction technology, but it is much further than resonant induction technology, we call it magnetic variable frequency transmission technology, but it is limited to the material factors on the earth, and it does not achieve the goal that we can expect."

Zhang Wenkai frowned, if he couldn't achieve the expected goal, what would happen, the gap in function, and finally asked the question in his heart: "How far can it be reached"?

On Cortana's holographic projection, Cortana suddenly disappeared, and in her place was a bunch of strange symbols, and after these strange symbols flashed, Cortana's projection was once again clearly revealed.

"The effective distance can reach less than 15 meters, and it is not possible to go farther."

15 meters? It was completely enough, even if it was fifteen meters Zhang Wenkai was full of confidence, so he took off his coat directly and prepared to start work.

"Cortana, what do you need me to do?" asked Zhang Wenkai with a stroke of his cuffs.

"This is the circuit diagram of the wireless charger" Cortana's projection disappeared again, and in her place was a complex circuit diagram.

Due to the lack of some corresponding instruments, it is very troublesome to carve a circuit board by hand, due to the limitations of various reasons, Zhang Wenkai took out his own electric soldering iron, and only used complex flying wires to realize the function of the circuit board, so the consequence is that the serious circuit board can not be seen, only dense lines can be seen.

Is this resistor put here? Okay.

And what about this transistor? Oh! Put it together with the onboard chip.

So what are these on-board chips for? Yes! If you don't understand, then skip this topic first.

The afternoon was spent in a question and answer

With his own rough welding technique,Finally completed the welding work of the wireless charger and the mobile phone receiver in the evening,Looking at this weird thing about the size of a TV set-top box,Zhang Wenkai also fell into a deep helplessness,Why didn't you study hard when you were in class,If you learn well,At least the technique can be much stronger than now,Looking at this somewhat rough weird 'box',Zhang Wenkai is still a little skeptical about the function of wireless charging,Adjust his mentality,Look at Xiao Na and ask:

"What else needs to be done next".

"You need to write the intelligent frequency conversion code, and the relevant files of the code have been transferred to your computer" Just look at Cortana's projection floating in front of many strange symbols, and the projection Cortana picks and chooses in front of these weird symbols, and then crumples the selected symbols into a paper ball, and finally throws it to Zhang Wenkai's computer, Zhang Wenkai saw that there was suddenly an extra file on the computer desktop.

"Cortana, what are the weird symbols?" asked Zhang Wenkai with some curiosity.

"Sir, it's the programming code of the home planet".

When he saw these weird symbols, Zhang Wenkai guessed that it might be some code program, but he didn't expect to be really guessed correctly by himself, if he used this code to write programs in the future, wouldn't it be that no one could crack it? Zhang Wenkai's eyes lit up, and he looked at Xiao Na with anticipation, and said, "Xiao Na, can this code be cracked by earthlings."

The code of the earth has formed a general standard, and then compiled into a computer-executable binary instruction through the source code, if you use new code, it will be impossible to crack it in almost a short time, so that the confidentiality can be the highest, imagine if you make the software, no one else can decipher it, you can only stare at it, what a thing to make yourself happy, so that other programmers despair.

"Theoretically, yes, this set of codes is very difficult to decipher, and it is already a difference in language family," Xiao Na replied to Zhang Wenkai's words.

"Teach me how to use this set of code in a while" Zhang Wenkai has realized the importance of this set of code; I decided to use this for everything that involves programming in the future

Cortana nodded and said, "Yes, sir."

Zhang Wenkai connected the microcontroller to the computer, set some parameters according to Xiao Na's requirements, and then hit the enter key, and a reading screen was displayed, but it was only a blink of an eye, and the code program had been written into the chip, and then the mobile phone receiver was written into the code program in the same way.

Holding this pile of wireless chargers spliced together from various components, Zhang Wenkai couldn't wait to plug in the socket of the power supply, took the receiver the size of a USB flash drive, and installed it on the data interface of the three-star mobile phone that he had used for 2 years.

Ding Dong, the prompt for charging the mobile phone sounded, Zhang Wenkai was excited in his heart, an irrepressible ecstasy surged to his heart, holding the mobile phone in his hand, one step, still charging, two steps, still charging, three steps and four steps, the charging pattern is still displayed on the mobile phone, one step and two steps (like the devil's pace), until the tenth step, the mobile phone is still prompting charging!

Zhang Wenkai clenched his fists, with a heavy breathing sound, still holding the mobile phone out of a distance of about fifteen meters, still prompting charging, and took a small step forward, looking at the mobile phone screen, Zhang Wenkai has a small loss, no longer charging, indeed as Xiao Na said, the effective distance is really only fifteen meters, but this feeling of loss was quickly replaced by great joy.

This is already a product that promotes the progress of the times, it will be the mainstream of future charging technology, and the world will say goodbye to wired charging.

"Cortana, this kind of wireless charger, is it harmful to people" Zhang Wenkai must be cautious, if this thing is harmful to people, it is really difficult to do, on the earth, even the safety of home wireless networks has attracted many people's questions; And this kind of wireless charger may produce harmful magnetic fields or electromagnetic radiation, which Zhang Wenkai studied when he was in college.

"Sir, there is no harm to people, because our chip is an intelligent inverter, the damage to people is almost negligible" Cortana's voice said without emotion.

"Great! Can it be made smaller? Zhang Wenkai hurriedly asked.

The wireless charger made by Zhang Wenkai is still too large, if it is smaller, it is more convenient to carry, and people prefer more delicate things.

Xiao Na explained to Zhang Wenkai while gesturing with her small hand: "If according to ordinary technology, the charger can be the size of a mobile phone, and the receiver can be the size of a keyboard button, if you use nanotechnology, the charger can be the size of a plug, and the receiver is only the size of a little fingernail, which can be directly welded inside the mobile phone."

Xiao Na's words made Zhang Wenkai surprised for a while, and the youngest didn't say it first. It can be made to the size of a mobile phone, and three stars need the size of a disc, not to mention that our charger is so far away that three stars can't be compared.

Zhang Wenkai's heart was very happy, punching the stick with three stars, and kicking the little apple of the American emperor, what a pleasant thing, uh, I thought a little too much. Zhang Wenkai's eyes couldn't help but look at the jack of the socket, if the weak current such as mobile phones can be realized, then I don't know if the strong current can achieve wireless charging, if it can, its significance is greater, it can be made into a radio refrigerator, wireless TV and so on.

"Cortana, is it feasible to make a strong wireless charger?" Zhang Wenkai asked Xiao Na the question in his heart.

In response to Zhang Wenkai's question, Xiao Na replied directly: "Yes, sir, you only need to modify the program code a little and replace some components with higher power."

Made, great, so that you can first push the mobile phone wireless charger to the market, wait for the sales to go up, make money, and then put the money into the strong electric wireless charger, Zhang Wenkai has some immature ideas for the marketing planning of the product.

"Cortana, you design a complete PCB." Zhang Wenkai instructed that all the product production can be completed by finding a foundry, only Xiao Na needs to set up a new PCB circuit board, so that the foundry can directly produce it, as for the written program, use the programming language of Xiao Na's home planet, try to make it impossible for others to crack, Zhang Wenkai racked his brains to think about what else was missing.

"Sir, the files you need are already on your computer," Cortana waved at the computer.

Seeing that Xiao Na sent what she wanted to his computer so quickly, Zhang Wenkai was also amazed, Made, it really deserves to be an artificial intelligence.

"How much does a wireless charger cost".

Zhang Wenkai almost forgot to ask about the cost, but when the words came out, Zhang Wenkai knew that he was worrying about it, even if the cost was high, he could make the price of cabbage for you in China, so he didn't worry about the cost.

"The cost is about 30 yuan, and if it is produced in large quantities, it will be even lower." Xiao Na said truthfully to Zhang Wenkai.

Sure enough, Zhang Wenkai was not disappointed, such a high-tech thing, the cost is only thirty yuan, and he can buy it for $199 or $299 when the time comes, and I believe that there are many people who are willing to pay for it; The joy of success is incomparable to anything, and at this moment Zhang Wenkai is full of confidence in the future.

For the protection of technology, Zhang Wenkai does not plan to apply for a patent, just like the Coke company, because to apply for a patent, you need to disclose relevant technical information, even if this wireless charger is in front of others, others can not crack it, why apply for a patent, just protect it as a trade secret, at most apply for an appearance patent.

Don't think about it so much for now, let's talk about it tomorrow, Zhang Wenkai rubbed his face a little tiredly, and said to Xiao Na: "Xiao Na, quickly tell me how to use this code."

There were too many experiences in this day, and there were great emotional fluctuations, and people were easily fatigued, so Zhang Wenkai dragged his somewhat tired body into the study of code.
