Chapter 053 Black Technology

The old classmate's venture capital friend is called Dong Yunliang, Boss Dong, and the problem he is most worried about about the Bitcoin clearing bank is the problem of financial licenses, how can ordinary private enterprises carry out foreign exchange business?

This business king doesn't dare to do it himself, but he likes to let others take risks and fool Boss Dong: "Now the RMB is already one of the four major international currencies, on the same level as the US dollar, the euro, the British pound, and the yen. ”

Boss Dong is not so easy to fool: "In order to crack down on international speculators shorting RMB, Hong Kong, the largest offshore market for RMB, has basically been abolished, the risk of this line is too great, we can only sell dog meat on the head of a sheep, I took a look, and the regular domestic website is not allowed to buy ** bitcoin." ”

Wang Fang: "Is there a store on Taobao that sells dark coins?" ”

Boss Dong was stunned: "What dark coin?" Oh, oh, the kind with the Jade Emperor printed on it, haha, there should be. ”

Wang Fang: "That's right, let's find a factory that prints dark coins, and let them help issue bitcoin banknotes, falsely claiming to be bitcoin commemorative coins, and you can sell them on the Internet in a grand manner, but in fact, this currency can be circulated through our network, and the process of selling dog meat with a sheep's head will run smoothly." ”

Boss Dong nodded: "This is a good way, it's better for you to be responsible for the website and app, anyway, there are 30 people in your maker hostel." ”

Wang Fang shook his head like a rattle: "No, I'm too busy, I still have a lot of projects, Boss Dong should invite another master." ”

Boss Dong smiled ambiguously: "It's not that you don't dare to do it yourself, let me be the big one, right?" ”

Wang Zhan: "Of course there are risks, how can there be high profits without high risks?" I really have a project in hand, so I won't do this kind of risky thing first, Boss Dong is smart, you can gather a group of people to open a company in the Cayman Islands, and then hire domestic technicians to execute it, I haven't operated in this regard. ”

Boss Dong laughed: "You are too chicken thief, you want me to do it alone, no, you have to go to the road, you can hand over the Cayman company to me, and the execution will be handed over to you, isn't this kind of thing known to fewer people as possible?" ”

Wang Bang smiled and said: "Then it depends on how much Boss Dong is willing to invest, and it is not cost-effective to invest less." ”

Boss Dong: "I will separate your technical team from the other operation team, you can rest assured, no matter what happens, it will definitely not involve you." ”

Wang Zhan: "Okay, I'll find a few young men to build a website and app for you, this confidential project can't be amateur employees, you have to find elites to do it full-time, you have to be responsible for opening a ...... for these young men." 12 to 15K salary. ”

Boss Dong: "Boss Wang also has to vote, this is the idea you came up with, don't tell me that you don't want to vote." ”

Wang Bang: "I don't have much money, I have invested it in other places, and I even invested in the drone project, so my 30 amateur employees are not enough." ”

Boss Dong frowned: "Drone? What's there to invest in this thing? The competition is too fierce, and the domestic e-commerce giants are all engaged in it, I'm afraid it's no fun. There are also DJI, who are professional, and everyone has made the plate into billions of dollars, why are you still involved? ”

Wang Bang smiled: "I'm joking, because it's really fun, my little plane has never been done before." Do you make it? Now DJI's Phantom4 is close to the price of 10,000 yuan, can only fly for 28 minutes, and the fastest horizontal speed is 20 m/s, which is the maximum distance of 33.6 kilometers, but I have a way to build a drone for less than 1,000 yuan, which can fly 50 to 100 kilometers, and it does not need batteries. ”

Boss Dong: "Uh...... Is there such a good thing? How to do it? ”

Wang Bang: "Slide, fly, plane!" It is a very smooth glide-glider-glide plane with a glide ratio of 50:1, which is a descent of 1 km, and can fly horizontally for 50 km. I first got it to an altitude of 1 km with a hydrogen balloon and dropped it, and I could fly 25 km away and come back, I didn't need the main engine at all, so it was cheap. ”

Boss Dong: "Big brother, no one will buy this kind of thing, right?" It's too inflexible, players can go wherever they want, you ...... Besides, it's not easy to land. The hottest thing now is vertical take-off and landing, because the runway is not easy to find. ”

Wang Bang: "Landing is what I thought of at the beginning, it doesn't matter if there is no runway, just throw a parachute and land like a Mars probe, our country's rockets are using this method to test and reuse." Besides, I'm not going to sell it to ordinary players, how good is it to use it directly for delivery, deliver it to the customer's head and hover over, the customer comes out and clicks the 'deliver' button with his phone, and a small parachute throws his package out. ”

Boss Dong laughed and said: "It's so whimsical, hovering at a height of 500 meters, customers can't see it!" One accidentally threw it on the roof of someone else's house, and I couldn't find it! I can only settle accounts with you. ”

Wang Zhan: "Uh...... This is not impossible to solve, let the customer hold a special sign in the open area, printed with a QR code, the plane in the sky to recognize this huge QR code, and then aim at it and throw it down. ”

Boss Dong: "Before you say that, you have to give the customer a customized brand?" There are too many premises. ”

Wang Bang was heartbroken: "Indeed, the current GPS positioning accuracy is too poor, otherwise there would not be so many problems." I had to install a telescope on the plane and see if I could recognize the QR code on my phone. ”

Boss Dong laughed: "No matter how you look at this project, it's unreliable, but I admire Boss Wang...... whimsical. Are there any prototypes? I looked, and it was fun to have fun. Let's be kind to all kinds of nonsense! ”

Wang Zhan: "Well, come, look at my flight room, I have a room dedicated to testing small planes." ”

Boss Dong was surprised: "You are still serious about making small planes, you really want to go and see it." ”

Boss Dong thought that there would be some wind tunnel blowing, but he didn't expect Wang Fang to use a few simple levers to simulate the wind blowing from all directions, his old face turned red, and said, "The real yàn room is a little simple, I'm sorry." ”

Boss Dong didn't mean to laugh: "Yes, very creative, so that the plane will not be broken, and it can save a lot of money." ”

Wang Bang pays the most attention to the speed of research and development, in fact, his small broken plane downloaded an open-source design from the Internet that is pleasing to the eye, and changed it casually, the appearance is quite ugly, and after adding more than a dozen sensors, it is even more aesthetically pleasing.

What Wang Zhan said next made Boss Dong awe-inspired: "Our practical method is an evolutionary algorithm, and the parameters are set to let the simulation program run by itself, so we don't know the details of the flight control system we made." ”

Boss Dong: "How's it going?" ”

Wang Zhan: "I can touch its wings, which is equivalent to an unexpected turbulence, and see how the automatic control system will respond." ”

He activated the automatic control system, and then abused the little plane in various positions, and the little plane would slowly return to normal. It looks amazing.

Boss Dong was interested: "It's a little interesting." It's amazing enough to simulate a wind tunnel with a connecting rod, but you don't know what to expect in the real world. ”

Wang Fang: "Yes, we also spent a lot of effort to get these connecting rod simulated wind tunnels. The wings of the glide-glider plane are very long, and they are greatly affected by the wind, and without the best asana control, everything is in vain. Now some fixed-wing developers have deliberately shortened the wing for this problem, which shows that the flight control of a large wing is not easy, and I wanted to use the evolutionary algorithm at the beginning. ”

Boss Dong watched the evolution program and ran up, and the plane swayed left and right, like the flight attitude under the real state.

Boss Dong is not a technical person, and he was blind at a glance on Wang Zhan's computer screen, only to see countless strange characters floating in the running parameters, even the imaginary number i has it.

Boss Dong exclaimed: "High-tech, this is." Why are there imaginary numbers? In other words, although I know such a thing, I have never understood the meaning of imaginary numbers, and I have actually seen it in reality. ”

Wang Bang smiled: "Haha, it's all because the mathematicians didn't get the name well before, what kind of imaginary number is called, which makes people think it's a meaningless number." In fact, it should be called the Y-axis number, and the ordinary real number should be called the X-axis number when there is a Y-axis.

The number of the Y-axis is actually the number corresponding to the number of the X-axis rotated 90 degrees counterclockwise, so i corresponds to 1, 2i corresponds to 2, and 1 rotates 90 degrees counterclockwise twice, which is 1 rotation 90 degrees squared, which is equivalent to the square of i, think about it, what does 1 become when it is rotated 180 degrees? -1. So there is a strange formula: the square of i is equal to -1, if you don't know that i is 1 rotated 90 degrees, you will be crazy, how can there be a number of squares equal to -1? ”

Boss Dong was confused when he heard it, anyway, he thought that Boss Wang was quite high-tech.

But he must see the other party's flight control measurement before he dares to follow up, capitalists are the masters who don't see rabbits and don't scatter eagles.

Boss Wang is indeed joking, he didn't have the money to engage in these creations before, which suffocated him, but now because there are too many projects going on at the same time, he is often complained by his partner Ouyang Fen.

He often starts a project and hands it over to free labor to execute, and he watches from the sidelines, and every now and then he has a new idea, and the rented house is already full of various prototypes of his products.

When I visited next door, one of the inventions that shocked Boss Dong the most was a "perpetual motion machine". Originally, he didn't believe that there was a perpetual motion machine in the world, but after seeing this invention, he felt that his three views had been changed.

This is a huge hydrogen balloon with a string underneath, and the buoyancy of the hydrogen balloon is equivalent to the clockwork of a mechanical clock, but the direction of the force is different. In the same vein, Boss Wang hired a watchmaker to make a zuò escapement to drive a rudimentary DIY generator, which looks like a teaching aid for a teacher to demonstrate to elementary school students in science class.

This hydrogen balloon always rotates the escapement and drives the generator to generate electricity. Hydrogen will escape, but Wang Fang designed a mechanism for electrolysis of hydrogen, so hydrogen can be automatically replenished all the time, and this small generator will always run like this, and there will never be peace, as long as the water is replenished.

Boss Dong was shocked: "What is this power?" ”

Wang Fang: "Enough to charge a few mobile phones." ”

Boss Dong was in a stirring mood: "This is black technology, handsome." ”

However, this is a useless invention, because with the unfolding of the "clockwork", the hydrogen balloon will fly very high and high, and it needs to be torn off by human flesh, Wang Fang has not yet designed a method that can be automatically recycled, but just wants to learn from Google balloons, using the method of inhaling air to increase the weight of the balloon and pull the balloon back to the ground.
