Gaiola de Faraday Blindagem Eletrostática
Neste vídeo podemos ver blindagem eletrostática nos corpos ocos e condutores. As cargas elétricas ao atingirem a superfície desses corpos circulam apenas pelo lado de fora pois campo elétrico em seu interior é nulo.
Esta é a justificativa para o fato de sermos orientados a permanecer dentro de nossos carros durante uma tempestade com raios. * * * * * * * ATENÇÃO : Não tente isso em casa! * * * * * *

How to Make Mini Power Generator Homegrown - With Step Motor.
If there's one thing that bothers me a lot is to be without electricity.
It's something that is very much needed and only we realize its importance when we ran it.
It is terrible to be without TV, listen to music or access the internet, it seems that when
we are in the dark these things are even more necessary.
So I was always trying to find a way to store energy, is
in automotive batteries, UPS batteries (deep cycle batteries) or on rechargeable batteries - those of tactical flashlights.
You can do this using a conventional charger connected to mains.
But I still had two major problems:
- And if the power outage is prolonged for several days?
- And when I go camping - For a lot like camping, but I think not
combines much be in the woods in contact with nature "Far from pollution" and
at the same time take a generator with gasoline to camp.
The solution would be to build a small generator, but I could charge my batteries. I think we've all seen dozens of videos that teach us to light up an LED with a little engine toy or printer, which does not provide energy in an amount that would be useful for our needs. On the other hand, we also have robust and laborious wind generators made with neodymium magnets.
An intermediate solution that met my needs was the use of stepper motors. For them it is possible, at low revs, reaching up voltage values and useful currents to charge 12V batteries (car batteries). The common electric motors require much higher speeds.
So if you plan to build one of these generators without much work, your first mission is to look for a stepper motor of major proportions.
These engines can deliver currents of 1A, 6A, or more, depending only on the engine size you have, with relatively low speeds.
Agora é preciso identificar as bobinas no interior do motor, de onde partirão os fios levando a corrente alternada para a ponte de diodos.
The easiest link engine is one that has only 4 wires, pink-orange and yellow-blue because there are two coils therein. We then connect the yellow to orange to obtain a single coil. This will make the desired voltage is reached with a lower rotation.
You can choose to build your own diode bridge or use a ready as pictured.
After this link your current is rectified, we must now filter it. This will be done with a capacitor 50000 microfarads to 25V
All assembled, lacking only that the generator of the rotating shaft (400 to 600 rpm).
Detail of the diode bridge connected to the capacitor.
Well, now I need to get your generator mechanical energy from any source, in order to convert it into electrical energy.
You can install it on the shaft of a wind generator, the wheels of a bicycle or, if you are lucky to live in a site or farm, where there is a stream or a small waterfall, you can turn it on the axis of a wheel d 'Water.
Mounted the circuit, you can now load a 12V battery and connect one or more outlets of cigarette lighters and connect accessories, and LED lamps to 12V.
Connectors to connect the battery to plug in accessories:
Accessories that will provide you with lighting, load on your tablet mobile phones etc.
Always use LED lamps
****** An important tip: If you have videos recorded on a flash drive you can watch them
a Digital Picture Frame (usually it has speakers, it plays videos).
****** I have here on the blog a post where I show that you can even connect your ADSL modem in 12V battery and enjoy your wi-fi signal when fall power.

******* In another post you can see how reusing the emergency lighting LEDs that no longer work, so you can connect it to your battery.
Thank you all

How to connect your ADSL modem on 12V battery when there is power outage.
In present day people are increasingly dependent on the Internet, to communicate, work, study and have fun.
So imagine the following hypothetical situation:
You came home and you want to finish that school or college research paper, reply to the email that important client or even just watch a movie after a hard day of work, and suddenly your neighborhood is without electricity for several hours .
Hard, is not?
I have good news for you.
You know that your phone line is still working right?
But did you know that your Internet signal is still also coming to your home?
Yes, the phone companies have batteries and generators throughout the network so that you continue to receive these services.
But how can I use the internet if my modem must receive utility power?
Note that what is on the grid is a converter that will receive 110V or 220V AC voltage, and will provide only 12V DC voltage for your modem. Now 12V DC voltage is just what you have in a car battery or those alarm batteries (deep cycle batteries).

Cable connector.
Identifying polarities.
Identify the polarity of your cable doing a driving test: Place the key multimeter diode selector in position, pull one of the probes multimeter the plug hole and the other end of a wire at the other end.
Connection to the battery.
Operation test
**** PLEASE CHECK BEFORE IF YOUR SOURCE MODEM IS 12V ****
Connect the plug on the modem and wait for him to call.
*****Attention******
Although the source of my modem indicate 12V, I plugged it into the outlet and measured with a multimeter the output value and only gave 11V. Despite that used a battery with exact 12V and it worked perfectly until the voltage drops to 11V.
When charging your battery, be sure the voltage exceeds 12V, modem security, and not discharge below 11V, for battery safety.
Watch Video: How to connect your modem to a car battery (12V). Not to be without internet.
I have a post here on the blog where I explain how you can build a generator to replenish your battery if the "blackout" lasts.
Watch the video: Power generator with Printer Engine. Here's how to do
Thank you, and even more.

Infinite Power Generator Withdrawing Stone Energy.
This post aims to explain the operation of Infinite Power Generator shown in the video "Infinite Power Generator Withdrawing Stone Energy" Channel "Life in Silicon".
First we must remember that energy can not be created we can just change the way that energy, for example, a power plant electricity was obtained from the transformation of gravitational potential energy in a body of water that was dammed in the dam's reservoir. This transformation occurs when the water is used to drive the turbine blades which will turn the shaft of a huge dynamo which in turn produces electricity.
Well let our generator.
First hold two pieces of aluminum foil on a table, we connect two wires to the foil.
These wires are now connected to the poles of a battery.
Now we cover everything with a wet sheet.
The aluminum sheets are under the sheet at the indicated positions.
We prepared a salt water solution (brine).
And we apply the solution in places where the aluminum foil under the sheet.
We prepare our LED attached to two other aluminum plates.
We use a resistor to limit the current through the LED avoiding burning it because we use a 12V battery.
Now place the aluminum plates in the regions of the sheet corresponding to the + and - terminals of the battery.
Keep one of the connectors of the battery off, put one of the first stones, and when you put the second stone, ask someone to connect the connector so that the stone is released.
There I go, everyone will have the impression that the LED lit with the contact of the stone. What really happened is that the stone has only enough pressure to keep the aluminum foil in contact with the sheet, allowing the passage of electric current through the LED. I could have also used dua potatoes, two glasses with water, a cup of coffee and a glass of milk, etc.
Unfortunately my friends, there is this infinite energy story. The closest this and the ridiculous amount of energy that can be achieved with the "Nuclear Cold Fusion" held in "tokamaks".
Thank you all.
Como Fazer um Gerador de Energia Infinita - O Segredo Revelado.
Esta postagem tem o objetivo de explicar o funcionamento do Gerador de Energia Infinita mostrado no vídeo "Como Fazer um Gerador de Energia Infinita - O Segredo Revelado." do Canal "Vida em Silício".
Primeiramente devemos lembrar que a energia não pode ser criada nós podemos apenas mudar a forma dessa energia, por exemplo: numa usina hidrelétrica a energia elétrica foi obtida da transformação da energia potencial gravitacional de certa massa de água que estava represada no reservatório da hidrelétrica. Essa transformação ocorre quando a água é usada para acionar as pás da turbina que irá girar o eixo de um enorme Dínamo que por sua vez produz a eletricidade.
Bem vamos ao nosso gerador.
Primeiramente prendemos dois pedaços de papel alumínio numa mesa, ligamos dois fios ao papel alumínio.

Esses fios são agora ligados aos polos de uma bateria.
Agora cobrimos tudo com um lençol molhado.
As folhas de alumínio estão embaixo do lençol nas posições indicadas.
Preparamos uma solução de água com sal ( salmoura ).
E aplicamos a solução nos locais onde estão as folhas de alumínio sob o lençol.
Preparamos o nosso led preso a duas outras placas de alumínio.
Usamos um resistor para limitar a corrente pelo led evitando sua queima pois usamos uma bateria de 12V.
Agora colocamo as placas de alumínio nas regiões do lençol correspondentes aos polos + e - da bateria.
Mantenha um dos conectores da bateria desligado, coloque uma das pedras primeiro e quando for colocar a segunda pedra, peça para alguém ligar o conector assim que a pedra for solta.
Prontinho, todos terão a impressão de que o led acendeu com o contato da pedra. O que aconteceu realmente é que a pedra somente fez pressão suficiente para manter as folhas de alumínio em contato com o lençol, possibilitando a passagem de corrente elétrica pelo led. Eu poderia ter usado também dua batatas, dois copos com água, uma xícara de café e um copo com leite, etc.
Infelizmente meus amigos, não existe esta estoria de energia infinita. O mais próximo disso e a quantidade absurda de energia que se pode obter com a "Fusão Nuclear a Frio" realizada nos "Tokamaks".
Obrigado a todos.

Como ligar seu Modem ADSL na Bateria de 12V quando houver queda de energia.
Nos dia atuais as pessoas estão cada vez
mais dependentes da internet, para se comunicarem, trabalharem, estudarem e se
divertirem.
Então imagine a seguinte situação
hipotética:
Você chegou em sua casa e pretende
terminar aquele trabalho de pesquisa da escola ou faculdade, responder ao email
daquele cliente importante ou mesmo apenas assistir a um filme depois de um dia
duro de trabalho, e de repente seu bairro fica sem energia elétrica por várias
horas.
Difícil né?
Eu tenho uma boa notícia para você.
Você sabe que sua linha telefônica
continua funcionando né?
Mas você sabia que o seu sinal de
internet também continua chegando até a sua casa?
Isso mesmo, as companhias telefônicas
dispõem de baterias e geradores ao longo de toda a rede para que você continue
recebendo esses serviços.
Mas como vou usar a internet se o meu
modem precisa receber energia da rede elétrica?
Observe que o que está ligado na rede
elétrica é um conversor que vai receber 110V ou 220V de tensão alternada, e irá
fornecer apenas 12V de tensão contínua para seu modem. Ora, 12V de tensão
contínua é justamente o que você tem na bateria de um carro ou naquelas
baterias de alarme ( baterias de ciclo profundo ).
Então o que você precisa fazer e
encontrar um cabo com conector que se ajuste à entrada de alimentação do seu
modem, identificar seus terminais + e
– , ligá-lo á bateria e conectá-lo ao modem.
Cabo com Conector.
Identificando as Polaridades.
seletora do multímetro na posição diodo, encoste uma das pontas de prova do
multímetro no orifício do plug e a outra ponta num dos fios na outra extremidade.
Ligação à Bateria.
Teste de Funcionamento
**** VERIFIQUE ANTES SE A FONTE DO SEU MODEM É DE 12V ****
Conecte o plug no modem e aguarde até que ele ligue.
*****Atenção******
Apesar de a fonte do meu modem indicar 12V, conectei o mesmo na tomada e medi com um multímetro o valor de saída e só deu 11V. Apesar disso usei uma bateria com exatos 12V e ele funcionou perfeitamente até a tensão cair para 11V.
Quando for carregar sua bateria, não deixe a tensão passar dos 12V, para segurança do modem, e nem descarregar abaixo dos 11V, para segurança da bateria.
Assista ao Vídeo: Como ligar seu modem numa bateria de 12V.
Tenho uma postagem aqui no blog onde eu explico como você pode construir um gerador para reabastecer sua bateria caso o “apagão” perdure.
