If memory serves, can direct current and alternating current be converted to each other?

After thinking for a while, Huang Si crossed out the idea of boiling water from gas to make a steam generator, which would cause the carbon dioxide in the house to increase, and he hadn't thought about what to do if there was too much carbon dioxide.

In the end, Huang Si identified a few entries he wanted to query:

Battery, solar cell, direct current and alternating current conversion method, charger circuit design.

Huang Si found a battery at home.

After scouring the way, he pulled out a few half-used No. 7 batteries from several remote controls.

Then I found a couple of dead batteries in the drawer.

Huang Sifu's forehead, why didn't you want to buy a few more batteries to spare at home? He always waited for the remote control or wall clock to run out of power before going to the supermarket to sell batteries. So there are no unused batteries at home now.

However, it is a reference at all.

Huang Si tried the microscopic observation of the battery, and found that his microscopic vision was very weak for the dense structure of the battery, he could see the paint molecules on the surface of the battery, but if he looked further, it was blocked.

The outer surface of the battery has a layer of tin skin, then the plastic packaging, and the top of the plastic is paint.

Huang Si directly took the obstructive layer of plastic away, leaving only the shiny battery tin skin.

However, the tissue composition of the tin skin is more compact, and Huang Si saw patches of dark gray tin atoms in the microscopic world, although there are individual defects, but on the whole, the arrangement is regular, and the combination is stable.

He tried to probe with his strength, and he could wrap individual tin atoms, easily copy them, and even register this arrangement in a book, and then make an identical tin skin.

However, his consciousness could not penetrate the tin skin and enter the battery.

It seems that this power only has the ability to create, and nothing else. Huang Si could only go to the kitchen to get a knife and cut the battery lengthwise.

There's a lot of black ink in the battery, and there's a black stick. What is this?

Huang Si recalled junior high school physics, this thing should be graphite, but is there any difference between powder and sticks? And how the battery is powered, he doesn't know.

These were all recorded by Huang Si in the form of notes. After taking experimental notes, Huang Si also dismantled the alkaline battery by the way, but he still didn't know why.

Well, it's time to use your laptop!

Huang Si quickly turned on the computer, opened the database without a trace of hesitation, and then searched for the relevant entries of the battery as quickly as possible, and then immediately recorded some key information with pen and paper.

At first glance, he realized that he had been completely mistaken, the dark gray atom of the battery sheath should be zinc, and the positive electrode of the battery was copper, the black round rod inside was a graphite rod, and the black powder ink was manganese dioxide mixed with carbon powder ammonium chloride.

By the way, he checked the key information of alkaline batteries and solar cells, and then picked the important ones and recorded them.

Before shutting down, Huang Si glanced at the lower right corner, 89% of the electricity was okay.

After regaining some strength after a good night's sleep, the next morning, after continuing to eat some fried noodles, Huang Si began to continue researching batteries. It's a pity that the battery design of the mobile phone can't be disassembled, and there is only one piece, otherwise Huang Si would like to remove it and take a look.

After a day of tinkering, in the evening, Huang Si finally made a real carbon battery.

When making this battery, he referred to the difference between empty and semi-electric batteries, and after many failed and repeated retries many times, a fully charged battery came into being.

And the creation book also records: zinc, toner, graphite, copper, manganese dioxide, ammonium chloride, carbon batteries, how these substances are composed.

Among them, carbon batteries are also divided into three versions: empty power, half power, and full power.

These are all picked by Huang Si himself, and theoretically as long as he is willing, he can record countless versions, but that is not necessary.

Next, Huang Si dismantled the mobile phone charger, and he had several chargers anyway. This is to look at the circuit structure of the charger.

In the next few days, Huang Si first cooked every day, then tinkered with the battery, and then read books to recover his strength, and exercised by the way.

In fact, on the third day, Huang Si made both alkaline batteries and carbon batteries according to the map, and there were already these two types of batteries at home, so it was not difficult to draw a gourd.

However, looking at a bunch of crooked and scrapped batteries, Huang Si thought to himself that the power of creation could not be decomposed and reused, and there was so much more garbage, what should I do?

After thinking about it, he simply opened the window and threw away all the garbage batteries.

In this kind of empty place, don't talk about public morality, anyway, there is no public here, only private.

Next, it is the production of the inverter circuit, he wants to convert direct current into alternating current, and then charge the mobile phone to test the water.

At this time, the phone has long been out of battery. Huang Si first analyzed the composition of various wires and recorded them one by one, then analyzed the composition of the charger, and then requisitioned the precious laptop boot time to look at the relevant design of the inverter circuit.

Fortunately, Huang Si graduated from computer science and is quite familiar with circuits. He first spent one day designing and manufacturing a circuit that uses batteries to charge the battery, and another day to make a very crude substation device.

But this is not enough, a voltmeter is also needed in order to stabilize the voltage at 220V of the mains.

The voltmeter is difficult to make, mainly because there is no corresponding device at hand for reference.

He dismantled the entire circuit in the distribution box at the door of his house and looked at it carefully.

Then, for a few special metal atoms, I searched for a long time at home.

In the process, something happened that Huang Si did not expect at all.

That day, he had just exhausted his strength, and he had eaten, and he didn't want to exercise or read for a while, so he hugged the creation book and nested himself in the sofa.

Huang Si can really feel his heartfelt love for this book, and this feeling has been there since before he picked up this book.

Thinking about it carefully, he didn't call him on the way to get off work that day, in fact, he didn't even call his name, but he just felt the call of the book in his consciousness.

Huang Si held the book in his arms, the book was quite large, bigger and thicker than an encyclopedia, but he didn't feel hard holding the book.

The book of creation and the creative power that the book gave Huang Si became like a part of himself after so many days of training.

His use of power and books is so natural that he doesn't even need to concentrate, he can do it with just a thought.

Huang Si looked at his book, and an idea suddenly popped into his head.

Has he never seen the structure of the book itself?

Why don't you take a look?

It has always been Huang Si's merit to think and do it, he holds the book in his arms, concentrates his consciousness on the book, and then manages to enter the microscopic perspective.

The world was rapidly receding around him, and Huang Si only felt that there was a flower in front of him, and his perspective had changed.

Huang Si saw two arms in front of him, and then, there was a scene in the room, but there were no books in this scene, and it seemed to be the opposite perspective from what he was looking at just now.

What's going on???

Huang Si was shocked, he realized that he was no longer himself, but had become a book, and the book was his body, he was being held in his arms, and then looked out through this perspective in his arms.

Can I go back?

With the thought of it, the perspective changed instantly, Huang Si looked around in shock, and he returned to his body.

It's scary.

Soul out-of-body experience?

No, it should be, changed the body?

Huang Si thought to himself that it was good that the book was unconscious, otherwise if it was really a soul swap and couldn't be exchanged, it wouldn't be as funny as in a comedy movie, this was a big thing related to whether he could be a human being!

Although this book seems supernatural, Huang Si doesn't want to be a book, he still wants to be a human.

Suddenly, Huang Si sensed that there was something more in the book, and he quickly turned the pages.

In fact, for Huang Si, this book not only feels intimate, but also like a part of himself, whether it is recording or perceiving its changes, it is as natural as feeling his own hands and feet.

The creation book was turned to the second page, unchanged, still the same things that had been recorded before.

He turned the third page, and then, the whole person was stunned.

The third page is densely packed with countless patterns and symbols, and what is even more amazing is that Huang Si can understand these things that seem even more difficult to understand than the Book of Heaven.

He quickly flipped back another page.

2nd, 3rd, 4th ...... It was only on page 104 that Huang Si saw the end of the pattern.

He didn't close the book for a long time, but re-read all the pages with the symbols printed on them.

Huang Si understands that this imprint is his own, his own structural pattern.

It's far more complex than anything he could make.

It seems that Huang Si wrote his own composition to the creation book as if he had just accidentally transferred his consciousness to the book.

It stands to reason that recording such an intricate pattern, according to convention, must consume a terrifying amount of power.

But Huang Si felt it in his body, and his strength was not consumed at all.

This must not be the usual record.

Huang Si tried to take other objects and put them on the creation book, from potatoes to ham to batteries, none of which were automatically rubbed on it.

It seems that only rubbing on oneself is special.

Is this the prerogative of the owner of the book?

Huang Si didn't know why, but he suddenly thought of a possibility, if he could be recorded in the creation book, did it mean that he could make one of his own?

Thinking of this, Huang Si shook his head again to dispel this idea.

Not to mention how much it will be to create a second self, the power consumption alone will be so terrible that I can't afford it, right?

Huang Si has long discovered that the size of the pattern generated by matter on the creation book is often related to its complexity, and is directly proportional to the power consumption at the time of manufacture.

For example, the power to make a whole bucket of water is 1, the power to make a bucket of flour is 3, and the strength to make a bucket of batteries is 25.

The ratio of the battery to the water molecule on the book is about 1:20.

Considering the extremely complex structure of the battery, it is also normal to have multiple fractions. Huang Si felt that it might be that he was prone to wasting power when making things that were too complicated, and that he might improve if he mastered power more accurately in the future.

However, more than two dozen substances have been recorded bits and pieces these days, and not even a single page of the book has been used up.

However, he alone occupies more than 100 pages .......

Thinking about Huang Si is incredible.

Therefore, it is impossible to create a second self, and it is impossible to create it in this life.
