Many old toy cars are abandoned in life, but electric toy cars can still be used, so I made a toy that can be enjoyed by both adults and children by using the electric mechanism. Actually, it's better to be a small generator. I made this one for intermittent emergency lighting.
Tools Raw materials.
1. Old electric toys with drive mechanism.
2. The old rechargeable flashlight requires that the light will still be on.
3. Wooden box or plastic box of appropriate size.
4. For other aluminum plates or plastic plates, I use a 2cm thick iron plate for the box cover, which doubles as a motor support.
5. A piece of iron bar is used to make a crank, and I use other ready-made cranks.
Steps:1Remove the motor from the toy, taking care not to break the two wires.
Most of the motors on toys are small DC motors, which generally have two wires, one red and one black. It is also important to note that the parts of its transmission mechanism cannot be lost. Some toy cars are driven together by the rear wheel and motor, which is simpler to make.
2.Make the transmission mechanism fixing bracket as needed. Measurement, perforation. Make a rocker arm at the end of the transmission mechanism.
3.Remove the head of the flashlight, and the light needs to be on. Pay attention to the red and black lines, red plus black and minus.
4.Fix the motor and transmission mechanism on the bracket made. And connect the red and black wires of the flashlight head to the red and black wires of the motor. Be careful not to misconnect.
5.It's basically successful to do this, and you can't help but turn the transmission mechanism and try it. If the light doesn't come on, you're turning in the opposite direction.
6.Confirm that the light is on, and prepare the box.
7.Fix the flashlight head in front of the box as well, and put the mechanism in the box.
8.Fix the rocker plate with screws, turn the rocker, and the light will turn on. Be careful not to rotate too fast, too fast and the voltage will break through the lamp beads. Because most flashlights are high-brightness light-emitting diodes.

Eating can generate electricity! You can cross it even if you eat!
-
It can lead to lightning or triboelectric electricity. Generators were needed to get a stable power supply, and it was clear that metallurgical technology was not so advanced at that time that it was impossible to build them.
-
There was no power generation technology in ancient times. Humans have long discovered the generation of static electricity, but it has not reached the level of producing electricity. The production of electricity was produced in modern times, which led to the advent of the age of electrical appliances.
In Xun Qin Ji, there is indeed a scene about the protagonist making power for his machine to charge. At that time, the protagonist was to use the scientific idea of modern galvanic batteries, and use ancient materials to make galvanic batteries with sulfuric acid as electrolyte, which does not mean that the ancient ancestors have mastered the power generation technology. Moreover, costume dramas are very different from real history, so please treat them differently.

In 1600 AD, the English physician Gilbert discovered and used electricity.
-
Answer: landlord. During the Qin Dynasty, the ancients had no electricity to use.
"Xun Qin Ji" is an adaptation of Huang Yi's martial arts**, which does not match the facts.
Humans only became aware of the existence of electricity after Franklin's famous experiment of "drawing lightning to the ground with a kite", so there was no electricity before.
Of course, the conditions for generating electricity were in place in ancient times. Both hydro and wind power can be used to generate electricity, but without a generator, there is no way to convert the mechanical energy carried by hydro and wind power into electrical energy.

What is the landlord talking about, I am doing e-commerce, in fact, now the e-commerce in the Chinese market is just starting and in a state of development, and it has not yet stabilized. But there are few people who really do a good job in e-commerce. Therefore, it is still too late for the landlord to change careers to do e-commerce.
In addition, it is now the Internet era, and I believe that in the future, it will be based on this, and micro-marketing will become the mainstream in the future, and e-commerce will be the general trend of future development.

I just want to do it, but I'm afraid I've been just thinking about it.

Batteries can be made with two metals and salts.
-
How ancient? What kind of power generation do you want? Solar energy may not be able to do it, the electromagnetic induction type mainly depends on the ability to make conductor wires, and the chemical battery depends on the smelting ability of the metal.
-
Theoretically, it can't be charged, because Yi Xiaochuan's LG mobile phone battery has a charge-discharge protection circuit. Even if he generates the same electrical voltage (left and right), the phone needs direct current. The voltage he emits is alternating current, and there is no rectifier module to make it DC.

There seems to be this plot.
But this is only YY, it is impossible, it only shows that the screenwriter has too little scientific knowledge.
-
calmly asked him what was the reason for calling his ex-wife, and if he needed to call his ex-wife ** again in the future, he could hit him in front of you. The most important thing for husband and wife to get along with each other is to be honest with each other, and it is easy to get into trouble when they hide it in their hearts, causing both parties to quarrel.

-
Understand why you are playing **, if it is not a serious matter, you must express your dissatisfaction with a clear attitude.
-
It's just an ordinary conversation, does it matter if he avoids you when he hits **? Will it tell you what they're talking about?
-
What can I do, if you want to break the mirror and reunite, you can continue to break them up.
-
Ask what's going on. It's not a serious quarrel to give a white face.
-
You just find a man to fight **, and slowly he will stop fighting.
-
It's just inconsequential conversations, don't worry, he'll tell you what they said.
-
It doesn't affect your family, and you don't have to mind in the case of feelings.
-
No problem! The key is that your husband's heart is with you, so it's no problem!
-
Take it seriously to help him solve his problems.
-
Ask him what is the matter. Deal with it together.
-
This one... It's hard to say, it's dangerous.
It can also be said that it is nothing.
-
It depends on what he hits the ** about.

1 all solar energy, if you can go back to ancient times, it is recommended that you bring some such products (solar charging) or bring more batteries, but you may not be big if you hit **, the mobile company has not yet opened there, brother can go back Don't forget to bring back my heirloom jade seal.
-
In ancient times, of course, you can't use your mobile phone, but if you get lost in the wild and can't recharge, you can use the method of sun exposure.
-
Brother, you are too thoughtful, if you really go to ancient times, even if you take a satellite ** to you, you can't get through, but if you talk about the ancient times to fill the mobile phone battery is a way, from now on with a solar puncher can be rushed.
-
To tell you that one of the most effective ways is to find a girl to discharge with you, and then you can charge it into your phone.
-
Take a mobile phone and rub it on a stone or fur to generate electricity, but the power is too low, at most do a hair tree experiment.
-
Brother, you are so talented, did you have electricity and solar energy in ancient times? It seems that there is no basic one, not to mention the mobile phone and charging the mobile phone, to write**, but also a little marginal, adopt it.
-
Isn't there electricity when you transport the internal strength?
-
In ancient times, who did you call when your phone was fully charged, and could you get through? Mobile did not have a service in ancient times.
In ancient times, Yangguan was now southwest of Dunhuang, Gansu. >>>More
The old man has passed away at home, if you are far away from home now, I don't think you need to pay tribute to the old man, first of all, you are renting a house outside, because the landlord, they are also very taboo in this regard, but during this period of time, try to wear clothes, to wear a plain one, don't wear too fresh colors.
