The manganese batteries used by the radio station eventually ran out, and the 284th Division, which originally had several generators, was lost in the tragic war, or simply blown up and burned.

In World War II, radio was already widely used in warfare. On both sides of the war, the Germans were more advanced in their technology, especially in tank units, and the commander of the panzer regiment could command all 152 tanks by radio.

The Soviets did a worse job in this regard, and after Kuznetsov left, they did not leave batteries. After successfully communicating with the Soviets in the southern part of the swamp, they were urgently relocated, leaving only three radios in the swamp.

In this era, the technology of batteries is not high, and the power reserve is very limited.

Without radio, everyone seemed to be abandoned, and Yevlov had no choice but to hope that Berekov would come up with a new idea.

Yang Mingzhi thought for a while, and suddenly had an idea: "Yevlov, are those trucks outside the swamp all electric?" ”

"Of course yes, those ZIS-5 trucks perform well. You mean replacing the radio station with a truck's battery? ”

"Maybe." Yang Mingzhi said calmly, "I estimate that the specifications of the two batteries must be different, so in order to adjust the voltage that can be used by the radio, we have to make a transformer." ”

Making transformers? Yevlov didn't know much about this? "Maybe we should bring in a professional electronics expert? Can you do it yourself? Or are you just an expert? ”

Yang Mingzhi just smiled, and after the meeting, he took the battery away, and ordered the car to be disassembled, and the car's battery was pulled out and sent into the swamp as soon as possible.

In fact, it is really helpless to make do with car batteries. Yang Mingzhi didn't know how Tuba Road in China solved the radio energy problem in this era, and it was estimated that it was a gasoline generator or a hand-cranked generator with manpower.

If it is said that manpower is used to generate electricity for the radio station, theoretically the current situation of Catfish Village may be feasible. He noticed the villagers' bicycles, which could be made into reliable man-powered generators with a major modification.

After borrowing the villager's iron pot, the family said they didn't have to return it.

In the evening, star fruit uses this to cook a pot of fish soup. The caught catfish is cut into sections, served with cabbage, and sprinkled with salt is enough. The aroma attracted a lot of people, and these warriors just smelled it, and they would never rob the commander of his good meal. When they saw the return of the chief, they saluted one by one.

"Go back, all of you." Yang Mingzhi waved his hand.

Star fruit sensed that her husband seemed to have something on her mind, and he frowned and held a black piece in his hand.

"Come on, let's have some fish soup, I've made it delicious."

Yang Mingzhi has been thinking about the battery, sitting on the stake that serves as a stool, holding the battery in his hand, the deliciousness of the food can't even attract attention, as long as the star fruit snorts twice.

"Oh! What did you just say? ”

"You're really, holding the black pimple, you don't want to eat." Carambola pouts.

Like a housewife, after the morning training, she returned to her lodgings and continued to repair the wooden house with a few soldiers. Now at least it is very suitable as a "forest hut". The dining table and stove are outside the house, and I have to continue to build the house and build a kitchen, so I'll make do with it for now.

Star fruit handed her husband a piece of bread. "Eat, if you want to study, you have to eat a full stomach."

Yang Mingzhi smiled, and the battery was placed on the table.

The two had dinner together, and to be honest, this girl's cooking was really good. After all, she is also a peasant girl, and she is really virtuous compared to the girls of the next century. "Now, little peach, your shoulder is still sore."

"It's okay, it's just a little sour. If I really couldn't stand it, I guess I didn't even have the time to cook. ”

"Well, you have to take care of yourself too, and there will be shooting training later."

After eating, Yang Mingzhi was still worried about the battery, and the soldiers lit some bonfires at night. There was no power station near the village of Catfish, and at this time, most of the villages in the Soviet Union were not electrified. The peasants still live in the habit of living at sunrise, but at night, candles and oil lamps are very popular.

Old Ivan, the blacksmith of the village, has been unusually busy with his work since the army entered the swamp. A lot of guns needed to be repaired, and his craft was put to good use.

That night, an uninvited guest came to visit. The next day, a foreign face, very polite to others, and each other are friends. "Berekov, you came here so late, do you still want to ask me about the bullet casing?"

His wife brought half a bottle of wine, and she knew that a conversation between men was indispensable for a drink.

"Aunt Kaya, no need, I won't be here for long this time." Yang Mingzhi waved his hand. He saw that the old guy was repairing the bullet disc of the DP machine gun, and some parts of it were deformed, so old Ivan had to use violent methods to knock the deformed parts back. The sound of crackling echoed through the room.

"So, you're here to ask about gunpowder?" Old Ivan asked absent-mindedly.

"No, Uncle Ivan, I just wanted to ask you if you have copper wires and silicon steel sheets here."

Old Ivan stroked his beard, "What do you say you want?" I have copper wire. Silicon steel sheet? Silicon steel?! ”

It's too professional, I'm afraid this guy can't understand it, Yang Mingzhi simply said that if he wants to make a generator, magnets, coils, and silicon steel sheets must be available.

Old Ivan put down what he was doing, "You follow me to the warehouse to have a look, maybe you can use this machine." ”

The warehouse was a wooden shed, and the machine, as Ivan Sr. spoke, was a scrapped diesel generator. As soon as he saw this, Yang Mingzhi was taken aback, "You still have this thing so much!" ”

Old Ivan held his pipe and remembered many years ago. When he moved the machine into the village, he simply wanted to solve his own power problem. Later, because it was too expensive to buy diesel, the machine was abandoned, and it was completely scrapped after a long time.

"The last time I used it, the diesel leaked and it caught fire. When I put out the fire, the machine was no longer usable, and I heard that you needed a motor, and it had one in it. Old Ivan pointed to the machine, and Yang Mingzhi on the side was full of smiles.

"Okay, let's just tear it down."

That night, Yang Mingzhi was at the house of old Ivan, and it was impossible to sit for a while and leave. He was afraid that his wife would be lonely at home, so he ordered the soldiers to call the star fruit over. My wife is still a child, and it is very necessary to educate her about all kinds of knowledge, and it is not bad for her to start with it.

Eventually, the generator was detached from the entire machine, and Yang Mingzhi removed the rotor.

"Magnetism generates electricity, electricity generates magnetism, let's change its power generation power now." Yang Mingzhi said to the star fruit, how can she understand this, but she thinks her husband is so powerful.

Yang Mingzhi does have this ability, with the help of the dim light of the oil lamp, he is doing a bunch of physical calculations, and finally calculates the length of the coil that should be wound. The rest is simpler, removing some of the silicon steel sheets that are used to make the "core" of the transformer. Silicon steel is so valuable that it must be put to good use.

All night, in the old Iwan's house, several people were busy building machines. Such a scene is remembered by star fruit many months ago, when her husband was studying weapons until late.

After a night of hard work, Yang Mingzhi was exhausted, he and old Ivan had the spirit of craftsmanship, and they were very excited to study the machine. Carambola couldn't stand it at all, and was arranged by the hostess to rest, and the new day's military training was also saved.

After putting in a lot of effort, Yang Mingzhi felt that there was no problem with his calculations. The electric motor was connected to Ivan's bicycle in old times, and the rear tire of the bicycle was removed and replaced by a belt that was attached to the hub, which was also connected to the engine. Such a person can ride a car, turn the rotor, and the machine can generate electricity smoothly.

As for the transformer, the silicon steel sheet was processed by old Ivan. The inscription of the manganese battery is very clear, the working voltage required by the radio station is not so perverted, and the simple version of the transformer that is only made at present is completely usable.

Yes, the machine is very simple, the transformer is a bunch of coils wound, the copper wire is not attached to the insulator, so it has to be simply and rudely wrapped with cloth copper wire. Overall, the machine looks stupid and coarse, but according to calculations, it can already charge the battery.

Yang Mingzhi couldn't stand it anymore, but his wife woke up first in the morning.

"Little Peach, give you a task, ride on the bike and pedal hard." Yang Mingzhi thought that his wife could ride a bicycle, but this was purely taken for granted, and the star fruit was confused about the bicycle and even a little scared. She still obeyed her husband's orders, but fortunately, the bicycle had been fixed at the moment, and she definitely would not fall off.

Yang Mingzhi planned to take a look at the situation first, the wires were all linked, and the star fruit on the side had already worked hard to step on the pedal, and the electric energy was continuously entering the battery.

Yevlov and Yerentina, who yawned, did not find him at Berekov's residence, and the soldier informed the commander that the couple had gone to the blacksmith.

So when these two came to old Ivan, they saw their strange behavior firsthand.

Yang Mingzhi had dark circles under his eyes and was in a very bad spirit, and he made gestures to symbolize victory. "Yevlov, I think I've succeeded. This is our generator and transformer, and you can install the battery in the radio station and try it later. I'll go to bed first. ”

Yerenkina knows better, she doesn't know how to build a machine herself, but she can also see that this should be a charging device. "This Berekov, is he really a specialist in mechanics and electricity? Yevlov, do you know his past? ”

Yevlov shrugged: "Who knows? This Chinese on the other side of the Amur, instead of asking me, you should ask Besika. You see, this girl is still struggling to ride the bike, and I guess you will have to wait until she is tired before asking. ”
