It starts with the production team driving the big truck

Chapter 172 Watch me DIY a radio with my bare hands!
Sun Jianping smiled, and calmly took out the parts he bought from the supply and marketing cooperative from his pocket, and waved them at the three people, "I can assemble the radio with just these things. Do you believe it?"

"Really?" Both of them expressed doubts.

"Brother Jianping, tell me how to fix it, I'll help you fix it!" Zhang Fucai was so happy that his front teeth were exposed, and he shouted loudly.

"Actually, the principle of the radio is very simple. It's just about signal reception and signal restoration. Fucai, please find me a wooden board."

"Okay!" Zhang Fucai jumped three feet high with joy!

Listen to the radio!

As the saying goes, it is not difficult for those who are willing to listen, but not difficult for those who are difficult. The structure of the mineral radio is very simple. There are only three core things inside: mineral crystal, variable capacitor, ordinary capacitor, and some coils wrapped with enameled wire.

Sun Jianping's second uncle is a technology enthusiast. When he is at home, he likes to poke fun at these weird things. Under the influence of his ears and eyes, he can also do things like cats and tigers.

"Just find a thread reel...help me wrap the enameled wire..."

Zhang Fucai helped him, and the two worked furiously for more than an hour. Lao Cao and Lao Zhang watched so nervously that they even forgot to eat hazelnuts.

"The master doesn't have a fire, this room is cold..."

When Mrs. Zhang Qi came back from work, she saw several gentlemen with their heads in a heap, all of them looking excitedly at Sun Jianping tinkering with a pile of copper wires. She took a second look but didn't understand what these gentlemen were doing. What? He groaned, took off his hand covering and scarf, and went to grab firewood to burn the kang.

"It's done!"

Everyone rubbed their eyes and saw several strange-shaped parts nailed to a wooden board. There were copper coils wrapped with wire reels, a round capacitor that looked like a flashlight bulb, and a long iron wire that was stretched out the window. .

"Jianping, I see that all the radios in Lao Xu's house use batteries. Don't we use batteries?" Lao Cao asked.

"Need not!"

Sun Jianping carefully turned the knob, and the sizzling sound of electricity came from the small speaker bought from the supply and marketing cooperative. The eyes of the onlookers suddenly widened!
There's real movement!

Jianping is awesome!
"Shh..." Sun Jianping squinted his eyes and turned the knob bit by bit. Along with the sizzling sound of electricity, suddenly, a brisk voice sounded!

"Tick tick, tick tick...the small speaker is starting to broadcast!"

"Mom, there's something going on on the radio!" Zhang Fucai was so happy that he almost jumped up! Shout outside the house!

"Really?"

Mrs. Zhang Qi threw away the water ladle and ran into the house. She came close to her son and listened to the weak but crisp sound coming from the simple little speaker. She narrowed her eyes with joy!

This kid Jianping...

so amazing!

I tinkered with the radio myself!

But after a few rings, the sound in this simple little earphone turned into a roaring sound of electricity again. Sun Jianping frowned and said, "Fucai, go hang the wire on the roof!"

"Okay bro!"

"I'm going to help too!"

Brothers Fu Cai and Fu Ming ran out quickly, moved the ladder and handed over the wire, and the sound of the radio became clear again.

"Old lady, go and take out the noodles you saved from the New Year, and I'll make dumplings stuffed with pickled cabbage for you to eat!"

Zhang Ziyi is happy!
This time I was really angry!
Old Xu is so arrogant!
radio……

Who doesn’t have such a thing?

Ours doesn’t even use batteries! save money!

I'll go to the supply and marketing cooperative tomorrow to buy some more parts, and let Jianping make another one for my daughter-in-law!
"This thing sounds so good!"

After working for more than an hour, the steaming dumplings filled with pickled cabbage were served to the table. Sun Jianping, Lao Cao and the Zhang family sat around, placing the ore radio in the middle of the table like a treasure, eating the dumplings and listening happily. The sound coming from the radio.

handy!

Comfortable!

happy!

"I didn't expect it, I didn't expect that our old Zhang would live the life of a city dweller!" Zhang Ziyi gave Sun Jianping a big dumpling, and he was so happy.

"Jianping, go back and fix one for me, no, two. Put one at our house and the other at the team headquarters. Then let the whole village come and listen! Look at how old Xu is blaring. The whole broken radio is not allowed to be listened to. I’m also afraid of running out of batteries…our radios don’t use batteries!”

After Lao Cao had eaten and drank enough, he leaned against the wall comfortably, feeling proud and proud!

Aren’t you going to let us listen? Let’s fix it ourselves!
"Uncle Cao, please keep your voice down, you can't even hear what the radio is saying!" Zhang Fuming muttered in a low voice, and Old Cao laughed, "Well, uncle, stop talking, let's listen to the radio together!"

The whole family was having fun together, enjoying the wonderful music coming from the radio, and felt warm in their hearts.

After dinner, Sun Jianping made another one using the "leftover" materials. With the experience of the previous one, the production of this mineral radio was very fast, and it was completed in less than half an hour.

The two radios rang together, like a chorus of mosquitoes. Sun Jianping saw that the adjustment was almost complete, so he removed the antenna ground wire, left this one to Uncle Zhang, and handed the remaining one to Lao Cao.

Lao Cao took it carefully, as if he were picking up a precious egg, for fear of accidentally knocking it, and if nothing happened when he returned home, he would regret it to death!
"Jianping, let's go back quickly!" Lao Cao urged anxiously.

The old man was still thinking about how many pieces he could listen to before going to bed!

"Well, Uncle Zhang and Aunt Zhang, we're going back first!" Sun Jianping waved goodbye to the two of them politely.

"Hold the dumplings!"

Mrs. Zhang Qi gave him a small enamel basin that was still warm. It was hard to refuse the kindness, so Sun Jianping had no choice but to accept it. He followed Lao Cao and walked home under the moonlight.

As soon as he entered the door, Lao Cao hurriedly asked Sun Jianping to lay the antenna ground wire and quickly assembled the radio!
The old man can't wait!

"Dad, what is this?" Seeing her husband's father holding a wooden board in his hand and carefully placing it on the kang, Li Xiuzhi came over and asked curiously.

"Radio!" The old man straightened his back!
Never seen it!

nice one!
"The radio doesn't look like this either. I saw it at Uncle Xu's house. It was boxy and looked like a wooden box..."

"It doesn't matter what you look like, as long as you can make a sound!" Lao Cao coughed, feeling a little annoyed by his daughter-in-law's doubts!
"If this can make a sound, wouldn't it be for nothing that Uncle Xu's family bought it?" Li Xiuzhi couldn't stop laughing. She thought her father-in-law was crazy about the radio. Just a few little scarred things could make a sound?
"Go, go, wait a minute and you will see me make a sound!" The old man was angry!
"Uncle, the wires are all connected, you can hang up the strings and try!" Sun Jianping stood outside, knocked on the window, and shouted.

"Okay!" The old man picked up two wires and hung them on the interface between the antenna and the ground wire. Then he followed suit and slowly turned the knob. Along with a hissing sound of electricity, a sound came from the earphones!

Li Xiuzhi's eyes widened!

Really...

Made a noise?
Lao Cao raised his eyebrows at his daughter-in-law with a proud look on his face and handed her the headphones.

Li Xiuzhi took it and put it to her ear, and a soft and sweet voice came out from inside!

"Dear listeners, please enjoy the Peking Opera excerpt "Shajiabang"..."
