I am a cripple in the Siheyuan. Who am I afraid of?

Chapter 59 This idea is too crazy
Yan Bugui is tempted!

Although he was a little embarrassed about what happened a few days ago, but with practical interests in mind, he still opened his mouth and asked: "Song Wu, do you think you can assemble a mineral radio like this for the third uncle? I have wanted to buy it for a long time. A radio, but you also know that money is not easy to come by." Yan Bugui looked at Song Wu with expectant eyes.

Naturally, Song Wu was not unhappy with the business that came to his door.As soon as he came from the Yan family and his son, he had already made up his mind to open a breakthrough from them.

If the cycle can be repeated like this, he can learn and practice at the same time, and make money without any delay.

To learn technology, you definitely need as many opportunities as possible for hands-on practice, the better.In this way, the biggest problem will arise, which is the cost of materials and accessories.

If there is a market for what he makes and someone is willing to spend money to buy it, it will naturally be the most beneficial thing.

If everything goes well, he will be able to learn electronic technology easily and casually without spending any money on his own.

Therefore, he felt that it was a very good time for Yan Bugui to come today.

Song Wu had a very nice smile on his face.

"Third uncle, judging from what you said, what's wrong with this? I'm quite happy that you can recognize my skills and believe in the things I make."

Yan Bugui's expression relaxed, and he quickly asked: "Look at how much you are going to pay for such an ore machine?" When he talked about Qian, Yan Bugui's expression became serious.

To be honest, Song Wu had already made up his mind and was not planning to make any money from the ore machine at the beginning.

Because his main purpose is to learn electronic technology, the so-called ore machine is just an entry-level option.So it only needs to be able to recover the cost and add a little bit of hard work.

The most important thing is that there are really no technical difficulties in the ore machine, and the number of accessories is relatively basic, so there is no room for price increase.

"Third uncle, I only charge some material cost for this kind of radio, plus a little labor cost. You can also buy the materials yourself, and I will only help you assemble it. In total, if you wear this kind of headphones, then It's a little more expensive. If you're willing to just use the earplug machine, it's much cheaper." At this point, Song Wu pondered for a moment.

"Bring earphones, I will help you install them and adjust the antenna. I have an ore machine that can accept two channels for 25 yuan. The one with 4 channels costs 30 yuan. If you don't want headphones, just use the earphone machine. If so, it can be 14 yuan cheaper."

"Is there anyone who can accommodate 4 stations?" Yan Bugui asked excitedly.

"Yes, I have another assembled one, but it doesn't come with a wooden box yet. That one can hold 4, even the ones in Tianjin." Song Wu nodded and said with a smile.

"The stage in Tianjin is good, there are more cross talk there." Yan Bugui muttered to himself.

After Song Wu finished saying what he needed to say, he stopped saying anything and sat on the chair with his legs crossed to drink the good tea from his cup.

This is called Jiang Taigong fishing, and those who wish to take the bait.

Yan Bugui struggled for a while, and then said to Song Wu: "I want the one that can hold 4 stations. Can you..."

"No, third uncle, this is just like me installing a bicycle for you. There's nothing more to say."

"Okay, then let's do this. I want the 4-channel one. You have to debug it better for me and make the sound clearer."

"Don't worry, Mr. Third, I will pull the antenna up big and high for you when the time comes, so that it can be used easily. By the way, Mr. Third, I have to keep my words straight. Don't blame me for not reminding you. The ore radio is The east and west antennas are pulled high. You must not listen to it during thunderstorms. I won't care if something happens. If there is thunder, you'd better pull down the antennas, otherwise you have to find a way to install a lightning rod or something. That would be too much trouble.”

At this point, Song Wu felt that he really needed to get an instruction manual or something, list out the precautions, and sign it by both parties.Just in case there was any dispute, he didn't want to get into trouble because of such a small thing.

So he said to Yan Bugui: "I will write down the key points of the operation for you when the time comes, and we will have to sign to confirm each other. Don't blame me for not explaining it clearly to you."

When Yan Bugui heard this, he felt a little nervous and asked hesitantly: "Is this ore radio still dangerous?"

"Look at what you said. There are dangers in burning coal stoves. The key is how you use it and whether you use it correctly? Didn't I just talk about the mineral radio? The antenna is pulled high. If there is thunder, then it won't Can you guide the thunder down? In fact, that's about it. The rest is very safe. Usually, if you don't listen, just disconnect the line. If you don't listen when it thunders, it's best to pull down the antenna. Nothing will happen. .”

Yan Bugui hesitated for a while, and finally decided to buy a mineral radio.

"Then you have to wait. Tomorrow I will make the wooden box and assemble it properly for you, and then I will pull the wires into the house for you."

Even if the matter is settled like this.

While Song Wu was preparing to make his wooden box for Yan Bugui, he was still thinking about the issue of raw ore.

Practice has proven that the volume of the ore machine made from natural copper ore is too low and the signal is too weak, which is mainly caused by the insufficient sensitivity of natural copper.

Now it seems that I still have to use galena.

But raw galena ore is hard to find. The ones sold in stores are packaged, so what’s the point of that?Song Wu had to turn his mind to the book he bought, which introduced the method of artificially making galena.

Judging from the description in the book, it is not complicated, and the materials are simple. It requires pure lead and sulfur powder, which are heated in a test tube.Of course, there are certain things to pay attention to when heating. You need to explore slowly and try a few more times.Then, wait until the test tube cools down and smash the test tube to get the galena.

"To learn electronic technology, you have to study chemistry." Song Wu couldn't help complaining.

In Song Wu's car repair shop.

An old man who came to repair his car asked him. "Master Song, why haven't you opened the door recently? I made two or three trips to repair something." There was a hint of complaint in his tone.

While repairing the car, Song Wu said calmly: "I'm really sorry for you. I have a lot of other things on hand recently and I'm quite busy. If you are really in a hurry, you can go to the east wing of the front yard. Find me."

The uncle chuckled and said, "I'm not in that much of a hurry. I'll treat it as exercise just by running two more times."

That afternoon, Song Wu installed Yan Bugui's ore radio for him.

So I started pulling out antennas and burying ground wires for him. After a while, I finally let Yan Bugui wear earphones at home and heard the cross talk and drums spoken in Tianjin.

Song Wu accepted the money and gave Yan Bugui an operating instruction sheet, signed by both parties, which was considered a disclaimer.

Then, he came out of Yan Bugui's house and no longer cared about how they went to grab the earbud machine.

Just then Xu Damao pushed his bicycle into the hospital and asked Song Wu: "What are you doing? Put an antenna on the roof of a house."

Song Wu briefly told him about installing the ore radio. The reason why he had the patience was that he planned to sell one to Xu Damao.

Who knew that people would look down upon her at all.

"To listen to the radio, you still have to use the kind sold in the store. It has a big speaker. It sounds so exciting. This ore machine is so boring. See you later." Come on, this business is not done, it is a waste of money. .

Song Wu was playing with the ore machine, and he became more and more interested in it. He worked for most of the night, still testing his natural copper ore machine bit by bit.He kept adjusting the contact points, testing the sensitivity of natural copper, and finally climbed to the roof to adjust the antenna.

Thanks to Song Wu's agility, otherwise he would have sneaked onto the roof in the middle of the night and wouldn't have woken anyone up.He worked on the roof for a while, making the antenna a little bigger.

When he was about to leave the room, he noticed movement in the courtyard.

In his perception, first of all, the door of Yi Zhonghai's house was pushed open quietly, and Yi Zhonghai, holding something in his hand, slipped out of the house quietly.

Then, what made Song Wu find it incredible was that the door of Jia's house in the west wing opposite was also pushed open.A figure walked quietly from the house to the courtyard.

The two figures walked one behind the other to the passage from the central courtyard to the backyard, and began to chatter in low voices, seeming to be entangled with each other.

Five and ten minutes passed.

Yi Zhonghai just walked across the corridor and quickly returned to his room.After a while, another figure walked towards Jia's house with something in his hand.

Song Wu has now clearly sensed that this figure is Qin Huairu.

"What's going on? Why did the two of them run to the corridor and do something when they didn't sleep in the middle of the night?" Song Wu couldn't tell what was in Qin Huairu's hand.
Yi Zhonghai weighed it out from the house and handed it to Qin Huairu to carry it home.

Song Wu felt like it was a dough bag, but he wasn't sure yet.

Could it be that Yi Zhonghai lent Qin Huairu food?

"Isn't that right? Who needs to be sneaky in the middle of the night when borrowing food?"

Song Wu was not ready to go down when he was on the roof. He sat quietly on the roof and concentrated on sensing the middle courtyard.He wanted to see if anything would happen next.

Unfortunately, the wind blew for more than half an hour and nothing was found, so he stopped waiting and got off the roof and returned to the house.

Now, I couldn't calm down even playing with the ore machine.I kept wondering in my mind, what on earth was going on with the scene I just saw?

In fact, he already had a guess in his mind.But this idea is a bit too crazy. This is a generation away. Is Yi Zhonghai really going to do it?
He couldn't help but think that some time ago he gave Qin Huairu an idea and asked her to borrow food from Yi Zhonghai.Could it have something to do with this?
Because there have been conflicts with the Jia family for some time, Song Wu has not spoken to Qin Huairu for a while.When the two met occasionally, they just nodded and said hello to each other.

Therefore, it is not clear what changes she has made recently that have led to such a big change.
