After paying the money, Ma Qingguo saw that Chutian was so generous and trusted his comrades-in-arms so much.

His face is also very face-to-face, obviously people are looking at his own face, which makes Ma Qingguo feel very happy.

After he left with Zhang Guofang, Chu Xinyue said worriedly: "Brother, after spending so much money, can we earn it back?" ”

Chu Tian nodded vigorously: "Steady profit and no loss, you can rest assured." ”

Chu Xinyue heard what her brother said, but she still didn't understand it, so she asked, "Brother, do you say that many people can buy second-hand household appliances?" ”

Chu Tian smiled: "If it is an ordinary repair and sale, it will definitely not work." But there is a process of renovation, and this process requires some craftsmanship. And it's definitely not something that anyone else can copy! ”

Chu Xinyue didn't understand it very much, but since Chu Tian said so, he must have his own thoughts.

After all, my brother's technology is there.

Chu Tian also knew that Chu Xinyue would never believe himself if he didn't see the actual product.

So he took Chu Xinyue out to buy tools, and bought some sandpaper and various paints, as well as various gadgets.

Chu Xinyue didn't understand, but she felt sorry for Chu Tian and spent money.

After coming back, Chu Tian began to disassemble the radio, and he completely dismantled it this time. Then start sanding the lid with sandpaper from 800 to 2,000 mesh.

Soon the semiconductor shell fades its color and becomes smooth.

Chu Tian carefully modulated the gray lacquer. Then apply little by little.

If you don't have a lot of skills, you can't do it.

After getting it done, Chutian began to dry, and then continued to start refitting the circuit board.

Strengthened modification of existing semiconductors.

The first is to streamline the modules, re-cut the boards, and add some small "patches" to the bonding.

After drying, after sticking, the flying wires begin to connect, and a special TV signal end is added.

A new button has also been added.

Chu Tian punched holes in the shell, and then finished assembling all the parts.

Chutian turned on the radio, and the signal worked normally.

Chu Xinyue looked at Chu Tianxin's lacquer color, and her eyes were straight.

High-end atmosphere, simple and elegant.

In short, it looks expensive.

After Chu Xinyue took it, she asked curiously, "This is finished?" But brother, what did you mod? Why didn't I see that? ”

Chu Tian smiled: "He motioned for Chu Xinyue to press it." ”

Then, the sound of a TV appeared on the radio?!!

Chu Xinyue looked at Chu Tian in surprise, she looked at him in astonishment and asked, "How did you do it?" ”

Chu Tian said with a smile: "It's just an additional signal modem, and the added part of the function is mainly to receive TV signals, but there is no video signal end, just the sound part." So, you can hear TV, which is equivalent to a TV accompaniment.

Basically, all you can do is listen to TV on the go. This is a functional upgrade, although it cannot be mass-produced, but for some customers who need special customized services, will it be very worthwhile? ”

Chu Xinyue nodded, and she muttered: "This kind of semiconductor that can listen to TV programs, to be honest, I want one." Some people can't watch TV, but you can listen to it outside! ”

Chu Tian couldn't help laughing, he whispered: "If I can get special equipment, I can also get a portable TV, but unfortunately there is no way now." ”

Chu Xinyue's eyes lit up when she heard this.

She didn't dare to think of this kind of thing, but how did she know that Chu Tian would have a smartphone far beyond the function of portable TV in the later life?

In this era, these things are unimaginable!

But Chu Tian didn't need to imagine, he just needed to improve according to his own ideas and within a reasonable range.

There is no need for mass production of this kind of thing, and the effect is definitely not good. He only needs to use his strong manual ability at this stage to make improvements, make something different, and a little trendy, and he can also make money, right?

Chu Xinyue held the semiconductor and listened to the show carefully.

It's not the same as watching Master Wei's TV.

After all, this is her and Chutian's first "home appliance".

Seeing that Chu Xinyue liked it so much, Chu Tian smiled and said: "This one is left for you to use, but you have to know your brother's ability, don't worry about it in the future, but you can also help your brother pay more attention to see if there are any particularly good painters and carpenters nearby." My brother wants to find some people to work with me to renovate home appliances.

After Chu Tian finished speaking, Chu Xinyue nodded vigorously and said, "Well, I know!" ”

If the semiconductors are sold, Chutian will sell them for about forty yuan, which will be the sky.

For Chu Xinyue to play with, Chu Tian was not distressed at all.

Anyway, it's okay, Chu Tian's eyes fell on the imported TV.

Anyway, I bought two pieces back and started some small modifications myself.

For example, the knobs, Chu Tian directly took them all off.

He replaced it with a knob for signal conditioning.

Then from their own outdoor antenna added a new number adjustment module for matching, directly behind the knob.

Chutian's transformation must cost a fee, but this cost is calculated together with the TV itself, and it is within fifty.

The biggest difference between Chutian and repairing old household appliances and selling them directly is that he does not guarantee that every household appliance can be refurbished, but once the renovation is successful, the price is definitely more acceptable than selling it directly refurbished.

Like this black-and-white TV, Chutian directly added another antenna, but this antenna does not accept TV signals, but accepts wireless signal remote control devices.

The remote control is also very simple, that is, the next channel, the previous channel, the sound is amplified, and the sound is lowered.

That's all, and then there's the switch.

A total of six signals are recognized.

Chutian can also achieve it, but the cost of parts is higher.

After the improvement, the original sound size knob has become the signal amplification size, and the function of the selection knob is still connected back and remains unchanged. The extra function is the additional wireless function, which is of course not an optical signal, but the most simple radio, if there are more radio signals at home, it will also be interfered with.

But at that time, there was at most one TV at home, where were so many sources of interference?

Therefore, Chutian improved well, dismantled the shell again, cleaned it, and continued to renovate.

Early the next morning, Chu Tian renovated it and put it on the table, a small gray imported TV, which immediately looked a little tall.

Chu Xinyue's eyes widened, looking at this new TV and asked excitedly, "Brother, can't such a TV be sold for five hundred?" ”

Chu Tian smiled: "Five hundred? This TV is 600 yuan, love to buy it or not! ”

Chu Tian said, and showed the "remote control" in a hurry.

He pulled out the antenna and pressed it.

The TV is on!

Chu Xinyue's eyes widened, she looked at Chu Tian in astonishment and said, "Brother, you are too godly, aren't you?!" ”

Chu Tian smiled, and then moved the TV to the car, thinking that he would take Gangzi and Zhang Yuan to sell electrical appliances today, plus collect old household appliances.
