Rebirth: My 80s

Chapter 30 Radio that does not require electricity

The sunrise in Gao Gao winter, shines on the south corner of my house.

Under the eaves, lazy people in Guifei lay on bamboo chairs, enjoying the warm winter sun and feeling leisurely and comfortable.

Since the brat finished his college entrance examination, the family has finally returned to normal.

However, brats are not necessarily completely normal.

He would squat in a corner, take a borrowed plane, and work hard on a pine board, causing wood flowers to fly everywhere.

The lazy man Guifei saw it very strangely.

He's pretty cool, I don't remember him ever learning this trick.

"What have you been doing, working all morning?"

"No eyes?"

"Interested in carpentry?"

The lazy man Guifei became interested and particularly supported this direction. He seemed to have some talent and would be good as a carpenter.

No need to farm and pound the soil.

As long as you have good skills, you can go out for at least one yuan a day and pay 5 cents to the brigade to buy work points.

Full work points!There should be no less dividends at the end of the year.

She still loses 5 cents every day.

The lazy man in Guifei calculated in his mind, 5 cents a day, 15 yuan a month, a year... I'll be a good boy!

A whole two hundred!
"Jiankun, learn to be a carpenter, just learn to be a carpenter!"

I will learn from your second uncle.

Li Jiankun was too lazy to offend him and continued to work.

A day later, a delicate little wooden box was formed, with just a few layers of paint and even hinges.

From Xiao Wang’s family.

The second sister saw him before leaving for work in the morning and wanted to go over to install some small items from her daughter's house.

This product was not given.

I'll just make another one tomorrow.

This box is waiting to be used.

As I said before, he is an experienced craftsman.

Those like Teng Ying are all younger brothers.

In the morning, the cat was in the room and assembled all the pieces that needed to be assembled. After that, he picked up the bamboo pole knife and went to the back mountain to chop a bamboo back.

"What on earth are you doing, and you want to learn to be a bamboo craftsman?"

The lazy man Guifei couldn't sit still anymore and planned to do his ideological work well.

Young people like to go astray.

The craftsmen are not good, they are not popular, and those who weave bamboo baskets for their homes will not be able to sell them for a few bucks.

Carpenters are different.

Who doesn't bring a few pieces of furniture when they get married?

When you die, you still have to make a coffin.

If you come over, you have to take care of the food and smoke, and call everyone "Master" when you meet them.

"Jiankun, listen to me. Don't talk about others. You always know that the second son of the lame master's family is a carpenter who hides away from time to time to eat meat..."

It felt like a fly was buzzing in my ears.

You can't just slap him to death.

Li Jiankun was busy with his own business, digging a hole in the roof of the house with a hoe, then returned to the house and took out a handful of enameled wire.

"Where did you get the wire? What is this for? Our house has no electricity?"

In the entire Qingxidian brigade, only the brigade headquarters has electricity, and it is still a thin wire pulled from the town with great effort.

The lazy guy from Guifei came over and squatted next to him and licked it.

"Oh, you're a loser, you've ruined such a good wire!"

I saw this guy using a knife to scratch off the raw enameled wire paint, and then made it into a mesh that could no longer be restored. He found rag strips and tied them to the bamboo.

Then stand the moso bamboo up, insert it into the hole you just dug, and bury it.

He took the other end of the enameled wire and returned to the house.

"I don't know what to do."

Guifei, a lazy man, scratched his head and decided to find out.

In the room, Li Jiankun connected the antenna to the wooden box, put on the headphones, and adjusted it slightly... 呲呲~
Hey there!

Then he sat down on the bench, leaned his back against the wall, squinted his eyes, and became intoxicated.

A long-lost tone.

It can only be heard in this era.

People in the future should feel this way. Why did the host in the 80s have a weird voice?
It's not weird, it's exciting.

the needs of the times.

The job that announcers do most these days is to spread good policies and the results of victory.

I will deliberately make my voice louder and sharper to match that emotion.

To be honest, the sense of substitution is very strong, isn’t it?

It's heart-pounding.

Guifei Lazy Man looked at me at the door with a mysterious look on his face.

He knew about the earphones, but why was he still shaking his head? Could it be possible that there was sound in them?
impossible!
It's impossible!

There are no electrical appliances at home!

He tiptoed over, hunched over, and moved his head closer and closer to the headphones...

Li Jiankun opened his eyes suddenly and was startled, "What are you doing!"

Just say that something foreign is approaching you.

"What are you listening to?"

"Listen to the song."

"Where did the song come from?"

"It's in the headphones." I believe you!
Bullying your father for being ignorant?
My private school is better than your crappy high school!

The lazy guy Guifei got angry, took one end of the earphones and stuffed them into his ears.

Gah!
"The hills and mountains are blooming all over, azalea~"

This dry man, who considers himself the most educated man in the whole brigade, has a pair of yellow old eyes that suddenly opened up as big as a bell.

this thing...

Unreasonable!

He heard it, it was a radio broadcast.

How can it listen to the radio without electricity?

If the sound doesn't follow the wires, could it possibly be flying here? !

Guifei, a lazy man, lowered his head and looked at the wooden box on the broken table. What kind of treasure is this?
Inside there is a copper coil wrapped with paper, a few small porcelain pillars, and two green stones...

gem? !
Where did the brat get the mysterious gem? He also made a box of his own, and he continued to activate its power!

"Jiankun, how could you do this? Where did you get the gem?"

After taking off his earphones, the lazy man in Guifei was busy asking questions with an excited look on his face.

Stories passed down from generation to generation, guess what?

It's true!
Today it has come true for him!
Bao, your sister.

Li Jiankun really didn't know how to explain this. Tell him about radio, would he understand?

"This is a new technology promoted by the state, called wireless radio. Well, this is called an ore radio. It's not a gem, just an ore. They are sold in the county for 8 cents for two."

No way, I need to be enlightened.

Otherwise, this guy could be shocked for a whole year.

In fact, the ore radio has been broken for a long time, otherwise he would not be able to buy all the materials so easily.

In the 60s, there was a movie called "Childhood's Radio", which showed scenes of children in mountainous areas making mineral radios.

Movies back then were not in the style of tearing apart Japanese soldiers, they were very real.

You see, kids can make it.

That means it's really not complicated.

The player circle defines the mineral radio as the simplest radio receiving device. Well, many people will play it in the future, just because their hands are itchy, oh no, it is for feelings.

Its principle, in plain language:

An antenna loop, after being tuned, is connected to the ore detector, and then the earphone is pushed to listen.

Its birth, without him, is just one word——

poor.

Poverty drives humans to rack their brains for fun.

When semiconductors first appeared, they were so expensive. How could ordinary people afford them?

According to the principle of semiconductors, some people use two pieces of ore of different materials to form a PN junction to replace the diode and use it for filtering.

Later, people used to call those radios that do not use a power supply and have only one semiconductor component in the circuit collectively called mineral radios.

Children in the future may not have seen it before.

There is an anime in Xinhai City called "Children Chasing Stars", which contains it.

In the early years, the state even published a book specifically to popularize mineral radios in rural areas.

It's called "Rural Radio Technology and Application", which is the same as "Pig Raising Manual" and "How to Capon".

They just didn't pay attention to it here.

There are many places in the north. When I walked to the countryside, oh, I thought I was at some kind of satellite position. There was a network of antennas above my head.

Speaking of play boxes and chat boxes, northern children always have some impressions.

"National new technology..."

When it comes to the country, Guifei Lazy Man has no doubts, but his newly awakened dream of being a fairy is shattered into pieces: "Then how could you do that?"

"What's up, I know how to do it."

When you can't explain something, remember to be rogue.

——Newton.

The lazy man in Guifei rolled his eyes and asked, "How much did it cost you if you succeeded in making this thing?"

This is a question that gets to the point.

Why didn't Li Jiankun just buy a radio?
As for my mother, she is always expensive, much more expensive than she will be in the future!
It’s not easy to buy if you have money.

I want a ticket.

Needless to say, if anyone wants to have a tube radio these days, it is definitely a luxury item.

Rich family.

Common models of tube radios from famous brands such as Red Lantern, Shuguang, and Panda are dozens of times larger.

A more luxurious one, equipped with a good wooden box and painted with bright paint, can easily cost one or two hundred.

Even those who can afford it will definitely put it in the most conspicuous place in the living room. When not in use, they have to cover it with a special patterned cloth.

It can bring out the appearance of the whole family.

There's also an artistic flair.

It's so amazing!

"It's not expensive, only five yuan." I thought this guy would talk to my mother about spending money indiscriminately.

Huh?
Unbelievably cheap.

Guifei, the lazy man, rubbed his hands and said with a smile, "Then you can make one for dad, and I'll give you the money."

He felt that he just lacked such a thing.

With it, life will be endlessly joyful.

Get my dog's head!

Ya Ting knows how to do business, take my money and pay me, and then I will do it in vain. You just threw your legs up, I bought it!
"Don't do it. It's hard work. You can listen to it when I don't listen."

He is going to college soon, can he still support the school?

Li Jiankun didn't realize at this time how much trouble this sentence would cause him.
