Building madman

Old Hong is very poor.

Don't look at the wind and wind in North America, but after coming back, he was impoverished.

Thirty million Franklin was'confiscated'.

The oil tankers and oil barrels went to evil bosses to repay the company's 2.5 million foreign exchange.

After finally bringing back two boxes of Cuban cigars, they were detained by the customs.

I brought a box with me, but I turned over my pocket and it was gone!

What made Lao Hong even more uncomfortable was that this trip abroad was not part of official business.

Therefore, you need to pay for the airfare.

In addition, he missed his salary and was absent this month. According to Tiancheng's strict management system, he will not only work for nothing this month, but also pay a'lost work fee' of 1,600 yuan at the end of the month!

I used to feel that Tiancheng's salary was quite good, but now I find that there are pits everywhere.

Today, the boss is invited to visit the scientific research results. He is thinking about buying cigarettes with a red envelope...

Unexpectedly, this crude tin box could make a lot of money!

In an instant, Lao Hong thought of incentive awards, project dividends, sales commissions...

"What do you foreigners do?"

"start running!"

"Printing an animated poster...what? Infringement? Will the group of ghosts in Wadao come to our small county?

"Yes, let's forget about North American animations. You may have two or five of you, shoot a news and send it back to North America!"

"What animation? Yixiu, Gundam, Bikachu, Pinball, Digimon, Blitz..."

"Sound? Find the Chamber of Commerce!"

"Colorful lights? Look for KTV!"

"The motherboard? Who did it look for before? Now it's mass production, place an order!"

After a blind command, Lao Hong suddenly thought of a very important question, and hurriedly ran to the side of Ge Xiaotian, who was watching around, "Boss, what about the coin-operator?"

"Did you go out and lose your mind?"

"How is it possible, or... IC card?"

"The soul of the claw machine lies in coin insertion. The metal coin falls, the carla la roars, and the exciting music starts, and the excitement is immediately brought up. This function is available by swiping the card?!"

"Um, if you use a coin acceptor...we can do it, as well as a coin reader, but it will take more than half a month to make molds, produce, and mint..."

"Are you stupid? The computer is popular, and the little eight kings are hot. Look at those game halls in Xiang County. Are there still people? Go to the surrounding counties and cities and say that we will fight hard and rectify entertainment venues in the future. Open the game hall! You take the opportunity to "recycle" the arcade machines at a high price, and it is estimated that a large number of them will be brought back on the same day!

"I understand!"

"Buy it and remove it. The joysticks, buttons, and speakers are all ready-made. You can use them after refurbishing! Keep the electronic screen, integrated circuit board, and controller for a retro project in the future!" Ge Xiaotian originally planned to throw a coin directly, but In the millennium, one dollar once, I guess no one can afford it, "including coin acceptors and coin readers, and copy them all!"

Lao Hong took a deep breath, he deserves to be a wicked capitalist, "However, most game coins are common, others bought game coins from outside..."

"I remember that the coin recognition device should be infrared induction. When the coin is dropped, the coil is energized to generate a magnetic field. The magnetic field penetrates the coin and passes to another coil. When the current is induced, it is a real coin. It lies in the material of the metal plate. If you adjust it, wrap the game coin in a half circle of plastic..."

"Dear godfather, this recognition function is a bit backward, I suggest using letter recognition!" Research director Jinx happened to pass by and heard these words and proposed.

"Oh?" Ge Xiaotian was a little surprised, how advanced is technology now?"Do you need to redesign coin acceptors and recognizers?"

"No need! I used to play arcade games a lot, and I helped others improve the coin recognition device. Just install a small device, it's very simple!"

"Adding letters to the original game currency, the pattern is so messy, the recognition ability is estimated..."

"No, it's on the outer edge of the coin, that is, the side that stands up. You can use a metal burner to burn'hong'!"

God is hong, Ge Xiaotian corrected: "Tiancheng!"

"Yes boss, Tiancheng!" Jinks looked respectful and pious.

"..."

It seems that this guy is more poisoned than the five fat boys.

Ge Xiaotian looked at Lao Hong, “Don’t do too high the recognition ability of the game currency in the early stage. It is specially designed to attract malicious people to grab a large amount of foreign game currency to catch dolls! Are you not doing a remote control system? Recognition, but to give them hope that they can move their paws and grab the doll, but they can’t get it, or give them one occasionally. In this way, won’t our game coins roll over? Turn back and engrave the sky into two Words, it’s ours!"

Old Hong was silent for a moment, "It's a bit difficult!"

"Which way is it difficult?"

"Fake money can also be played!"

"Fuck, you still do electrical work? I can think of a way out of my layman, can't you think of it?"

"Boss, I'm smart, I understand!" Jinx completely offended the bewildered Lao Hong, "Generally speaking, the recognized real currency will enter the next program. And the unrecognized counterfeit currency will be vomited. Come out! The boss meant, let us make a "pseudo-recognition" motherboard in the counterfeit currency channel, or to make a program that can be played with any currency, cast "counterfeit coins", start this machine, it can move its paws, and It can be grabbed, but there will always be various accidents, such as loose paws, grabbing early, shaking badly, and speeding too fast... In short, it is difficult to operate! Others play with real money, and they use real money. Playing with counterfeit money can be'bad' to doubt life!"

"Incisive!" Ge Xiaotian gave a thumbs up, "Jinx, I suddenly admire you!"

"Thank you boss, I will work hard!"

………………

With the plan, the claw machine project started quickly.

Welding cabinets, assembling rails, discussing IC orders with component manufacturers, and improving game programs...

Before the evening, the Machinery Department pulled a batch of arcade machines from the Jishi Cultural Bureau that were blocked a long time ago.

Dismantling, summarizing, packing, and batches sent to Daqingshan Tiancheng station for restoration...

Busy night.

At noon the next day, Ge Xiaotian took the lead to sit in front of what might be the world's first crane machine.

Well, this is a sample.

Lao Hong and others watched.

As a maker, you must know how to play and have already installed anime puppets in advance.

"Have you ever counted? How much does this one cost?"

"About three hundred!"

"so tall?"

"Iron sheet, steel frame, integrated circuit, research and development program..."

"Right, how much?"

"Two hundred catties!"

"It's too heavy, what if you fall down and hurt someone?! Also, the cost is a bit high. Replace the metal cabinet with the fiber plastic we use to build cars!"

"In this case, the cost should be reduced to two hundred, and the weight...less than one hundred and fifty catties!"

"Almost!" Ge Xiaotian dropped sample game coins.

Kara la la la, dripping, dazzling, brilliant lights...

Control the joystick, shoot the button, rotate the paw, two continuous shooting...

"No, when I'm about to grab the doll, I need to add another'hold on' program!"

"Will we lose our lives?"

"Be close to the people! How many people can play in the early stage? Gradually increase the difficulty, and then introduce different styles and different sizes of dolls, and the paws should be differentiated, such as key pendants, sweater pendants, etc., all with small paws!"

"understood!"

"Today, on the thirteenth day of the first lunar month and before the Lantern Festival, 20 sets were made, half of them were placed in the Crescent Moon Children's Entertainment City, and the other half were placed in the Xiaoqingshan Supermarket!" What kind of old-fashioned sand sifting machine is there on our site, which is similar to the one used for pounding sesame oil, do you still have it?"

"No, now we all use crawler sand screening machines, and we can directly mix them in one step."

Ge Xiaotian took out paper and pen, "Change the old-fashioned sand sifter, add a small car model, or the Chinese zodiac, locomotive, elephant, etc., shake it back and forth slowly, and add different types of nursery rhymes. This coin acceptor can be used for five minutes at a time!"

"It's simple, all old machinery is piled up in the warehouse, sorted out, and can be modified."

"Be sure to pay attention to safety, the motor must be replaced!"

"know!"

………………

After a busy day, Ge Xiaotian returned to the Crescent Office in the evening.

Coincidentally, the Biyadi manufacturer who had been silent for two days also sent a letter of intent for cooperation.

The other party is very sincere, not only considering the weight of electric vehicles, but also listed the impact of temperature changes on the battery in spring, summer, autumn and winter.

It's just that Ge Xiaotian was dizzy with the data like a ghost drawing.

After a long silence, he looked at his secretary:

"Xu Ling, what about the junior high school physics textbook I bought for self-examination?"

"In the second cabinet from the left!"

Look for it.

I found the chapters on current, capacitance, voltage, and power in the textbook. Ge Xiaotian saw the early morning and only then understood the meaning of Ah, mAh, kWh, Wh, Kw, V, vAh, etc., the relationship between each other, and the correspondence formula.

Drink a cup of tea to digest and digest, then pick up the pen and paper and start calculating.

In the current market, there are two cheapest power batteries: nickel-cadmium batteries and lead-acid batteries.

The price given by the partner is definitely far lower than the market price, with an average of 0.3-0.5 yuan Wh.

Nickel-cadmium batteries are poisonous and cannot be used.

Lead-acid batteries... seem to be toxic too, but this is currently the mainstream in the world.

Write and draw.

Take the data of the previous battery-powered bicycle as an example:

400 batteries, 800 yuan, 7Ah.

Suppose Tiancheng spends 800 red notes to buy a lead-acid battery pack, 1600Wh.

Calculated according to the 48V standard output voltage, 1600Wh48V is approximately equal to 33Ah.

One is 7Ah and one is 33Ah.

The comparison of figures has fully explained how expensive Lao Hong’s battery pack is.

Calculate the trip again.

Assume that the motor power is 350W.

Average speed average current: power voltage=350W48V=7.3A

Travel time = average battery capacity current = 7Ah7.3A, which is approximately equal to 0.96h.

Calculated according to the speed of 30Kmh, the theoretical stroke=0.96hx30Kmh=28.8 kilometers.

However, the itinerary is affected by the load and temperature, and there is no battery control system, and it will eventually be about 20 kilometers.

Apply lead-acid battery pack.

Driving time = average battery capacity current = 33Ah7.3A, which is approximately equal to 4.5h.

Calculated according to the speed of 30Kmh, the theoretical stroke=4.5hx30Kmh=135 highway.

One is about 20 kilometers and the other is about 135 kilometers.

Even if the load and temperature have a great influence, the travel gap between the two is as high as six times.

However, lead-acid batteries have a big disadvantage. With the same capacity, Lao Hong uses 400 lithium-ion batteries, but the volume and weight are only one third of that of lead-acid batteries!

This gap can be almost ignored if it is placed in a car or bus. If it is placed in an electric vehicle, plus it is poisonous...

Ge Xiaotian looked at the second document given by Biyadi.

This is the lithium iron battery being developed by the other party.

Judging from the complete name, there are some impressions.

It seems that the electric bicycle I bought before squatting behind bars used lithium iron phosphate batteries.

It is small in size and durable, and it is also the mainstream energy source for that world in the future.

The preliminary quotation from Biyadi is: 4-5 yuan Wh

Ge Xiaotian calculated again.

Eight hundred yuan, you can buy 160Wh, divided by 48V, 3.3Ah!

More than twice as expensive as the lithium-ion battery pack assembled by Lao Hong!

Goodbye!

With a little melancholy, Ge Xiaotian looked at the time. It was one o'clock in the morning, "Huh? Xu Ling, why haven't you gotten off work?"

"I'm afraid you need me to deal with something."

"All the arrangements have been arranged, what can be done..." Ge Xiaotian wanted to go back earlier, but it was all set. "By the way, where do you live with Brother Liu?" (Going to be a duck with Lao Qin project manager)

"It lives in the small high-rise building that President Qin bought in Area C."

"No decoration, right?"

"Installed a window and door..."

"It's freezing cold, what's going on!" Ge Xiaotian rummaged through the drawers and found a bunch of keys. "Building 801, Area A, should be decorated. You move in first. If it feels okay, I will send you as Marriage room!"

"No, no, boss, too expensive!"

"Which so much nonsense!" Ge Xiaotian said, and threw the key over.

As a developer, a batch of houses will be reserved for every real estate in case of emergency.

At the beginning, there were ten sets in Xingyue Bay, Xiang County. Later...well, no one wanted them, and then they gave them to Qiye to deduct gold, and he didn’t want them. Finally, they threw them to Tianshi for training. The decoration is pretty good.

"Xu Ling, ask you something!"

"Battery?"

"Yes, lead-acid batteries are suitable for electric vehicles, but they are not what I want. If they are developed by others, it will take a long time..."

"Boss, I heard that our resident scientific research room is very powerful. A new type of engine has been developed in a short period of time, and the performance is far superior to that of our peers. Why do we cross-line to make electric?

"The future trend, fuel is getting more and more expensive..." Ge Xiaotian suddenly woke up.

There are many things that replace fuel, such as nuclear energy, hydrogen energy, bioenergy, combustible ice, and natural gas!

Why is it limited to batteries?

The battery is just a container. If you create a device that directly generates electricity, or a conversion device that can store other portable energy...

For example, the simplest "pure ethanol engine"!

"Dididi!"

In the middle of the night, the phone rang suddenly.

Ge Xiaotian glanced at the screen, it turned out to be Yang Dianfeng who was helping to deal with the tank in the Far East of Bingxiong.

"Old Yang, why do you call now?"

"Finish!"

"Oh? Thank you for pulling!" Ge Xiaotian smiled. The Lao Hong and tank incident is finally over!

"Huh? You won't ask for details?"

"It's not too late to come back and talk!"

"I'll go back and talk, but no one will help you deal with the big stall here!"

"What do you mean? We bought the tank and armored car, what else do we have to deal with?"

"The land you bought!"

"When did I say I bought land?"

"At the dinner table that day, it was the time you were drunk. Didn't you say you want to buy Siberia?"

"???"

When did I say it?!

Ge Xiaotian looked dumbfounded, "No, do you always have any misunderstandings?"

"Misunderstanding, my relatives, Lin Yang, and my grandson, Yang Lin, both of them can testify! Or it would cost tens of millions to buy a few abandoned tanks?! I was excited when I listened to your rhetoric to serve the country with a curve and regain the homeland. I, carrying a wine bottle and wearing a vest, went straight to the airport..."

"..."

"60 million red banknotes, 10 million Franklin, remove the tanks and armored vehicles, leaving...134 million. You need to find an agency to buy land on the ice bear. I happen to have it, so I won’t charge your agency fee. The land on their side is calculated in hectares, one hundred red banknotes per hectare per year, the longest ten-year period, a total of 150,000 hectares were bought, and most of them were sent by the Bingxiong Navy, saying that you have time to see Look at the'Admiral Gorshkov' and the'New Rossis' aircraft carrier, the original words are: cheap, brother price!"

"..." I'm afraid it's not because the other party thinks I'm stupid and rich?!

"Boy, 150,000 hectares, what are you going to plant? Although it is still too early to thaw, the ice bear agricultural control is very strict. You must prepare seeds and machinery in advance and declare! By the way, when you send someone over, you must Don't bring pesticides, or I will be investigated and I won't be able to help!"

"No, wait!" Ge Xiaotian looked at Xu Ling, "150,000 hectares, how many mu is it?"

"Two and two hundred and fifty thousand mu!"

"..." Ge Xiaotian swallowed, "What do you old man suggest me to grow?"

"Aren't you talking about growing soybeans, producing soybean oil and soybean meal, and providing Li Xiuxiu with a steady stream of pig feed!"

"..." Ge Xiaotian asked again for the constant supply of feed for pigs, "What do you suggest to grow? I don't understand!"

"Potatoes? Barley?"

"What's the point?"

"Bing Xiong likes to eat potatoes, if barley, transport it back to the country for brewing!"

"Wait! Brewing?" Ge Xiaotian picked up the battery that he had calculated for a night, "Can I make industrial alcohol? Pure ethanol?"

"Must, are you stupid? Sorghum and barley are the main ingredients for winemaking!"

"Then grow barley and sorghum!"

"You have to send someone, how can I have so many people?"

"When have we been short of people? My people have arrived in the Northeast!"

"Sure enough! I knew your kid was going to buy Siberia!"

"..."

You are really misunderstood, I sent them to sneak into Siberia, logging, quarrying, and grabbing gold!
