"Why, I can't call that name?" Jin Chi walked in as he spoke, melon seed face, Liu Yuemei, tall, fair and delicate skin, wearing a white shirt, a little out of place with the surrounding environment, she lives here, but it is likely that the heart is not here.

"Of course not, I thought it would be a male teacher!" Fang Dajun said embarrassedly.

When he started working, he couldn't think about personal problems, this was his way of doing things, and he immediately beckoned Jin Chi to go outside, the carpenter's room was not suitable for calculations, and he needed a relatively quiet environment.

It's also a coincidence, as soon as he went out, he happened to meet Yang Chuntao, as soon as he opened his mouth, the other party quickly arranged an office, just on the first floor, and the door was also wide open, not afraid of others gossiping.

In fact, he is still bound by his thinking, he is a fifteen-year-old and a half-year-old, but Jin Chi is in his twenties, and he can't form the conditions for a lonely man and a widow at all.

"Jin Chi, you can help me calculate how to use the power distribution battery to make a formula that can release the current." Fang Dajun said seriously.

"Oh, what are you doing out of this thing?" Jin Chixiu's eyebrows twisted, making him even more coquettish.

Fang Dajun pondered for a moment and said: "It is mainly used to power the yellow eel, so as to find some pocket money for the children, the current released cannot be too large, the human body can withstand the current of 36V, if there is no problem with 24V in the dry field, 12V in the paddy field is also absolutely safe." Therefore, the output is calculated according to the current of about 12V. This current can only be used to electrify yellow eels in the field, or small fish and shrimp in small rivers, and adults and children will not be in danger. ”

Jin Chi's brows relaxed, "Well, I understand what you mean, but if you calculate according to the current of 12V, the water level is not enough as long as the water level is a little deeper, is it possible that you really just want to sell the electric yellow eel loach for money?" ”

Fang Dajun said with a smile: "The current range of output is very small according to 12V, it will not exceed the distance of half a meter, I plan to make two sets of equipment, one set of 12V for children, one set of 24V for half-grown children or adults, and 24V I want you to add a transformer to increase the voltage output of 24V." But such equipment will be dangerous to make, and I don't think it's appropriate, so you can also help think about it and give some advice. ”

Jin Chi put his hand on the table at this time, knocked on the table with his fingers frequently, with a thoughtful look, and after a while, he showed a smile, "I came up with a way, you can put the positive and negative ends on a stalk, and then make a barbed wire, and go around it according to the loop, so that you can control the range of release in the case of increasing the voltage, as long as you don't violate the rules, there will be no problem."

The transformer requirements are not high, we can use copper wire to wrap one, but the battery still needs to be purchased outside, and we also need to buy some wires back, and it is best to also need a soldering iron and some resistive devices. ”

Fang Dajun gave a thumbs up when he heard this, the golden pool in front of him was really powerful, because he was limited to age and environmental problems, he didn't explain some of the words just now, but he didn't expect that they were basically made up by the golden pool.

"Well, then follow your plan, and put on a pair of waterproof rubber bucket boots for the person who is, and it will be even more foolproof."

Immediately, Jin Chi began to draw the circuit diagram of the motor, the technique is very professional, so professional that Fang Dajun is a little incomprehensible, uh, it is estimated that the current physics textbook is too old.

"Okay, you can make it according to the circuit diagram, and there should be no problems." Jin Chi clapped his hands and smiled, obviously satisfied with his work.

"Well, with your estimate, only calculate the cost of purchasing materials, not counting labor, how much does a fishing machine cost?" Fang Dajun asked the key, he is a clever woman who is difficult to cook without rice!

Jin Chi frowned and said, "Even if you don't count labor, it is estimated that it will cost about fifteen yuan, which is too expensive." ”

Fang Dajun breathed a sigh of relief, "Are you interested in participating, I promise to make money!" ”

"What do you promise? A piece of equipment will cost more than a dozen yuan, and the production team will plough the fields one after another next month, and the time for you to electric yellow eel is only one month at most, not for me to hit you, and you can't even get the capital back. Although Jin Chi's words were a little heavier, it was also for his good, because he invited her to eat a flower roll last time.

But Fang Dajun didn't look at it that way, and he also touched Jin Chi's surname, lacking adventurous spirit and having a thin skin, such a surname is more likely to be a teacher, or find a stable job, and forget about doing business.

"Are you interested in making a bet with me, I can earn hundreds of yuan in a month with a fishing machine without a penny." Fang Dajun said confidently that in the two years he worked along the coast, he was deceived five or six times, and he couldn't prevent it, and he could be regarded as a doctor after a long illness, and the means to fool people were quite rich.

"I don't believe it, what do you want to bet on?" Jin Chi had a look of interest in his eyes.

"Can you bet on a date?" Of course, he can't say this, and when he compares Jin Chi with Li Yulan, he still likes Li Yulan more, "If I win, you can find a way to help me ask Li Yulan to go to Beidou for a day." ”

"What? Do you like Lan Lan, how old are you! Jin Chi was extremely surprised, he really didn't expect him to say such a thing.

"What? Can't you? If I lose, the conditions are whatever you want, as long as I can do it. Fang Dajun answered, no matter how this gamble is calculated, he suffers, but if he even cares about the gains and losses of emotional matters, it will be too tiring to live.

Jin Chi was going to refuse, but when the words came to his lips, they became, "Okay, you're going to lose." ”

"Hehe, not necessarily. I'll let you know who's winning and losing in an hour. Fang Dajun smiled a little smugly.

Subsequently, Yang Chuntao was invited over in front of Jinchi, and directly blew it, leaving the process aside, anyway, Yang Chuntao expressed his willingness to pay on the spot, and after ten minutes, he directly sent a hundred yuan to him, and also told him the price of yellow eels and loaches in the county.

"Dajun, don't worry about going to make a fishing machine, Auntie will find a way to support you, and you will be able to send the wire to Carpenter Jiang later." Yang Chuntao's eyes lit up and he instructed.

As soon as Yang Chuntao left, Fang Dajun pointed to the banknotes and said, "How about it, I won." ”

The reason why Yang Chuntao was able to give money so simply was that he was fooled, and because Jin Chi was present, so that there were witnesses, and he would take the invoice back for the purchase of materials, and the rebate of a few yuan at most from it was already up to the sky, so it didn't matter if the money was given to him now.

"If you win, I won't lose unjustly, because I really didn't expect you to be so shameless. Don't think I can't hear it, you not only deceived Aunt Yang, but also planned to deceive the children of the whole commune. Jin Chi's eyes widened, as if to see how dark his heart really was.

Fang Dajun said righteously: "You only saw the process, but ignored the result. By doing so, I can let the children earn money through labor, I earn intermediary fees, and Aunt Yang increases the value of the idle money in her hand, and it is only those people in the county who are relatively wealthy in living conditions who pay for it, and they also buy delicious food that is worth the money, so it is not a loss. In a big way, this is called the economy, and if there is no flow of buying and selling, how can it drive agriculture to create wealth? ”

Jin Chi was stunned for a moment, and then immediately said: "You are quibbling, if you try to persuade the adults of the children to let the adults directly pay for the equipment and separate you and Aunt Yang, then each participating family will be able to make more money, anyway, you are too shameless." ”

Fang Dajun was a little speechless and pulled his hair in a mess, and said loudly: "Do you think that if everyone does their own thing, will there be a conflict in the end when they compete for the yellow eel?" Will those cadres be red-eyed? When selling yellow eels, you are sure that no one will deliberately lower the price, for example, some people will think that it is enough to sell for one dollar, and the people next to you will see it, maybe they will sell it for nine cents, okay, you sell nine cents, Lao Tzu will sell eight cents, if so, what will the result be? Think about it, if I didn't come forward to unify and coordinate, and if Aunt Yang didn't find a way to sell wholesale, I wouldn't dare to say absolutely, but at least eighty percent of the chance that the yellow eel would seriously damage the harmony within the commune, the adults quarreled every day, the children fought every day, and you, the teacher, would also be affected. ”

Although Jin Chi knew that Fang Dajun was quibbling, no matter how high-sounding he said, it was not for her own money in the end, but she was speechless and couldn't find words to refute.

"Alas, I finally understand why Uncle Wang called you Fang very much."

Who thought that Fang Dajun said: "No, you still don't understand, you think that I can blend into the commune with just one threshing machine, and Aunt Yang can casually give me a hundred yuan to build a fishing machine." ”

"Could it be that you have done anything more shameless?" Jin Chi suddenly became worried about his good sister Li Yulan, this person is too powerful, Uncle Li will definitely not be able to parry, and Lan Lan will fall into the clutches of the devil if he loosens his mouth a little.
