The Lancet wanted to make a hand card by itself, but unfortunately it has not succeeded so far.

Hand card technology is confidential, is the frontier of science and technology, the science and technology contained in it, broad and profound, can not be made by anyone. It is rarely possible to accomplish it by one person, and it requires division of labor and cooperation.

Otherwise, what do you want major manufacturers to do, everyone can make it, and everyone is their own "manufacturer".

In that case, the hand card manufacturer will not go out of business, there is no group manufacturing, where is the progress and development of science and technology, where is the better equipment to serve the people.

Even if you make it, it won't be able to connect to the telecom operator normally.

Hand cards or communication devices made without permission are illegal and not allowed by the state.

You make it and play with it, you can, if it becomes a commercial activity, then it's over.

You have to.

It is possible to go to prison for several years or to receive the most severe punishment of "banishment".

In anything. There is an exception to everything.

When it comes to making your own hand cards, the Lancet is an exception.

Why is The Lancet an exception? This has a lot to do with the fact that she has enough congenital conditions.

The first must be her knowledge.

She now has enough knowledge to deal with most of the manufacturing problems.

The second one, which is that there is good device support.

This can be said to be too lacking, and there is such a manufacturing machine on the bacteriological spaceship.

It can help you print and manufacture products that are exactly the same as the design plan according to your thinking and design scheme.

This is the modern 3D printing manufacturing technology of the future. The machine with this technology is called a 3D printing machine.

The Lancet has always wanted to convert this tablet controller into a hand card.

He had been meditating for a long time.

It's a pity that the plan has not yet come out.

The Lancet had been thinking about this whenever she had a free break.

If she can make a hand card, then she can contact her grandfather and find Huayu who has lost contact.

How nice that would be!

If you wait here for your grandfather to contact them, time is not allowed.

The human world is not right with the time here.

In the human world, an hour is equivalent to a day here. If you calculate it like this, you have to wait until what year and month!

So, The Lancet, thinking of making a hand card, or communication device, on its own.

She also thought about building a transmitter to convey information by radio. But today's world is an era of advanced technology, so old things are no longer used. Even if you make it yourself, who can receive it when you send it out? No one will accept it, and it will be useless if it is done.

The Lancet has been studying the construction and production of hand cards for a long time in his own time.

The operation and software aspects of the hand card are no longer a problem. Although the interface is not very beautiful, the basic functions are still there.

As a programmer, you don't have that much time to do art work.

Take The Lancet, for example!

She has a bold personality and does not procrastinate. The same is true at work.

So let's take a look at her dialing software! It's very different from what we usually see.

The dialing software he designed is very concise.

The whole interface is gray and white, and there are only two pop-up box touch buttons on the screen, one dials and one hangs up, and the two buttons are aligned up and down. The previous button says "Dial"; The next button says "Hang Up". That's all, nothing more superfluous.

Hand card software without entering numbers. How do I call the other person's phone number correctly?

It turned out that in order to see the results immediately, she wrote the 11-digit Arabic numerals of the phone number to be dialed directly into the dialing software code. In layman's terms, just like we usually call, we have already called once, and we only need to press the "redial" button to dial again.

The phone number already exists, just press the dial key box.

However, there is no Huayu phone number now, so it can only replace "01234567890" with random 11 Arabic numerals. As soon as you get the number, fill it in and change it, and then press the dial button to complete the dial-up call.

The biggest headache for him is the hardware. As we said before, the hand card is the embodiment of high-tech technology. It's not that simple to make. The production data that can be found is 2G; 3G； 4G communication protocol. Even the 5 G communication protocol that serves as a standard framework for modern communication protocols is very rare.

Not to mention the 5 g+20 on top of it.

The various wiring directions on the circuit board have been designed for each module.

For example, the RF module of the receiver and the transmitter; the assembly route of chips and components;

The most important of the baseband modules is the CPU design. This piece can stop the lancet.

It took a long time to get through.

If one day it is made, she can use the number simulation software to simulate the call sign, and the number called can be simulated into any number, for example, the one starting with 400. Any number drawn from 955 will do. This simulated number will be displayed on the opponent's hand card.

This is a bit like the illegal number change software of the time decades ago. At that time, some people used it to do illegal things, such as telecom fraud. In response to that sentence, "Nuclear can destroy the earth, or it can build the earth, depending on how you use it?" The Lancet is "building the planet." ”

What made her full of confidence was that she had searched for radio frequency signals from telecom operators a few days ago, which showed that the laboratory had been wired, and the comrades must have thought of it and contacted us by phone.

But the Lancet, on second thought, this accident may be really very big, otherwise it would not have broken the rules and pulled the telephone line in a crowd.

Thought to this.

The Lancet began to get nervous, and if the machine in the lab didn't work well, or if the experiment failed for some reason, they might never be able to go back.

"No, it won't. Trust them. ”

The Lancet remembered that the comrades would never give up on theirs.

How many difficulties they have overcome, this little accident is nothing, technically solved, no problem.

A small thing is nothing.

The ground began to regain its mood and had the determination to win.

At the same time, it is also necessary to strengthen self-help.

The key is to study the hand card and get in touch with the old slippery professor.

With it, information is exchanged, and any problem can be solved.

Before receiving an order, it is necessary to continue scientific research.

By the time we get back to normal, maybe we've done our job and can go home.

With this thought, New York, to no longer wander. With a strong conviction, he continued to study and explore the science of the microcosm.
