Ten minutes later, Feng Xiaotian, who was racking his brains, suddenly jumped up from the chair, and his head hit the beam of the house due to the excessive movement, although the collision hurt, but Feng Xiaotian didn't care at all, because he had found the key to the problem - the signal receiver had no power supply!

This is a very simple problem, but it is also an easy problem to be overlooked, this signal receiver is removed from the radio, when using the radio needs the battery to provide energy, install it on the computer, naturally need to provide it with electricity!

Feng Xiaotian laughed twice, and then took out the battery from the radio, connected the battery to the signal receiver with two copper wires, and after doing all this, he couldn't wait to look at the computer monitor, this time, there was finally movement on the computer monitor, but Feng Xiaotian was stunned after looking at it - why did it appear that it was garbled characters?

Yes, what appeared on the computer was a garbled stream, many messy characters filled the computer screen, and then changed line by line, Feng Xiaotian was dazzled, and after a pause, he moved the mouse to operate, but the garbled stream did not disappear because of his operation, they were still changing on the computer screen.

"This ...... What is this for? ”

Feng Xiaotian was confused again, this situation occurred, at least it means that the signal receiver has received wireless information, but what is displayed on the computer is garbled code stream, how to explain this?

Feng Xiaotian began to think about it, this time he didn't have much effort to find the reason, in fact, the reason is very simple, because the electromagnetic wave signal received by the signal receiver is the frequency of the radio, not the frequency set by the computer, if you want to solve this problem, unless you can know what band the wireless network of the computer is, Feng Xiaotian doesn't know about this problem, so he can only give up at present.

"Alas......"

Feng Xiaotian let out a long sigh, he just started the modification action with a lot of enthusiasm, originally thought that the matter would be solved soon, but the truth is not so simple, the computer is a machine, any link has a problem, it may cause improper consequences, these garbled streams that appear on the computer screen, is the digital signal of the radio, and at present, it is impossible to convert them into text, but I am afraid that it is impossible, because the radio is a sound playback device, and does not have a word processing function.

Feng Xiaotian was a little frustrated, but he was soon relieved, this kind of problem occurred because he didn't have relevant knowledge reserves, and it seemed that he would have to strengthen this knowledge more in the future.

Thinking of this, Feng Xiaotian turned his gaze to the books piled up in the corner, the books in them covered many aspects, one of them was about radio signals, this book was specially picked up by Feng Xiaotian from Lao Li in order to repair the radio, so he just looked through the content about the radio signal in it, as for the others, he didn't pay too much attention.

Feng Xiaotian turned off the computer, got up and took out the book from the stack, lay on the bed and studied it carefully, in the dim light, his expression seemed very focused, and the room fell into extreme silence, only the occasional sound of flipping books could be heard.

At four o'clock in the morning the next day, Feng Xiaotian got up, he didn't sleep all night last night, but this did not affect his spirit, on the contrary, Feng Xiaotian at the moment seemed very pleasant, through last night's all-night study, he already had a more intuitive understanding of radio knowledge, wireless signals are indeed a very magical thing, and different bands will cause completely different results.

Feng Xiaotian got up and washed up briefly, and then went out with the snakeskin bag, and as usual, he began to run for life again.

It's winter vacation time, so he has plenty of time, Feng Xiaotian has already made a decision, he must take this opportunity to understand the magic of the computer, as for artificial intelligence, it is still relatively unreliable at present, and he doesn't even learn to walk, so he wants to go to outer space?

At half past six in the morning, Feng Xiaotian came to the gate of Lao Li's courtyard with a whole bag of waste on his back, as usual, Lao Li was squatting under the corner of the wall to brush his teeth, it seemed to be an appointment, every day at this time, Feng Xiaotian would arrive at Lao Li's house on time, and Lao Li would squat in the corner at this time every day to brush his teeth, this is a tacit understanding between picking up rags and a paid item, it is quite magical.

Feng Xiaotian pushed open the courtyard door and walked in, and said with a smile as usual: "Uncle Li, you got up really early." ”

Lao Li rinsed his mouth, stood up and said with a smile: "You're just early, Xiaotian, you wait first, I'll wash my face and come out." ”

Ten minutes later, the two settled the bill, Feng Xiaotian's income today is seven cents and five, which is very good, Lao Li handed the money to Feng Xiaotian, Feng Xiaotian took the money, but did not leave, he set his eyes on the waste books piled up in the corner, Lao Li smiled and said: "What? Do you want to buy books again? If you want, find it yourself, and remember not to mess things up. ”

Feng Xiaotian smiled when he heard this: "Don't worry, I'll pay attention." ”

The two of them are familiar with this, Lao Li nodded when he heard this, turned around and went into the house to cook, Feng Xiaotian came to the pile of books, searched carefully, his goal was only one, that is, books about computers.

Since computers are not yet popular, it is a new thing, so there are not many books on this in China, so there are naturally not many relevant waste books that Feng Xiaotian can find, and after more than 20 minutes of hard work, Feng Xiaotian only harvested two books.

Feng Xiaotian sorted out the stacks of books, walked into the house with two books, Lao Li was cooking, and when he saw Feng Xiaotian coming in, he took off the dry tobacco pouch in his mouth and knocked it on the stove, and said with a smile: "I picked these two books today?" ”

Feng Xiaotian nodded and smiled: "Well, you can weigh it." ”

The two books weigh less than three catties, and according to the price of waste paper, it originally only cost less than two cents, but in this way, Lao Li is considered to be in vain, according to the agreement made by the two, the price of Feng Xiaotian to buy a book is eight cents a catty, and Feng Xiaotian paid two cents and a half after the most reluctance, and then left with the book.

In the following days, Feng Xiaotian still got up early every day to pick up waste and sell it for money, and after returning home, he was learning computer knowledge while doing various practices on the computer, time flew by, and before he knew it, the Lunar New Year had arrived.

The New Year is dispensable for Feng Xiaotian, because they are alone in their family, and there is no atmosphere for the New Year at all, so Feng Xiaotian is disdainful of this - it can also be said that it is a bit of a deliberate evasion.
