Build a homemade electroscope

Through the Science in the XXI feeds looking with the mind, I find an interesting post with botched electronic experiments. And there I discover the Electroscope and the search for information begins.

Un electroscope it is a really simple way to know if a body is electrically charged or not.

The electroscope was created by William Gilbert And although it is no longer used today as much more powerful and effective devices have been developed, it seems ideal for a physics experiment to be done in a laboratory class.

A diagram of the electroscope assembly would be as we see in the image obtained in Thales

 

electroscope construction scheme

And here we can see some commercial electroscopes

pay electroscope

After watching minutes and minutes of video, I have opted for these two, the first with good explanations and the second with a good and very animated montage.

And if you want more information, follow these links.

  • Electroscope. One of the best links I have found.
  • Aluminum electroscope. This is the simplest model of electroscope I have found, no glass bottle, nothing, extremely simple.
  • Electroscope on Wikipedia. A link to document a little more.

Build electronic electroscope

Now we go a little further and leave a scheme that we have found for the construction of an electronic electroscope.

The assembly scheme is as follows.

electronic home electroscope

The necessary materials are:

  • 4,5V battery
  • 2 «faston» terminals
  • flexible copper wire
  • Universal polka plate
  • 2 resistors 1kOhm
  • 2 resistors 100 kOhm
  • 1 diode 1N4007
  • 2 BC557 transistors
  • 1 BF245C transistor
  • 1 red LED
  • 1 green LED
  • Soldering tin
  • Welder

You only have to do tests by rubbing various materials.

    You know very little about Argentina, the work of teachers and what education is in our country. Don't be ignorant !!!!!

  2. You are fine, it shows that you do not know anything as they will not know how to use them that the world is like this and you too that let it go well there is a saying that says throwing to qerder it is here or it is not so ahaaaaaaaaa ¡¡¡¡¡¡¡

    And then that slobbery ahaaa I clarified a mystery qende qor not tell you another idiot thing better I shut up he told you this with a lot of affection and do not bother byee you take care of me.

  3. I would like if you could help me, I made an electroscope but the sheets do not work for me, no matter how hard I try, it does not work I would like support ……… ..

  4. the video of how to make the electroscope is very interesting. but if they put the original audio on it, it would be better so we understand the procedure better ...

  5. LOOK AS THEY MADE THE ELECTROCOPE I TRIED IT BUT NOTHINGAAAAAAAA THIS PIIIIIII DOES NOT WORK…. (FORBIDDEN TO MENTION) HAHAHA ANSWER YES.

  6. uy if you fucking Argentinian kulero shit shut up that your country is shit and don't blame us for your dad being poor and they don't have money $$$ marikon starved for shit

  7. It seems to me that saying that Mexican or Argentine teachers work the least is a matter that we should discuss in our respective countries. It is not good to victimize ourselves by saying that we are the ones who suffer from the most lazy teachers, since we, thanks to a teacher, can be reading and answering these kinds of mistakes.
    Whether or not we are subject to the Sunken Stables (USA) is not because of the teaching profession, but for historical reasons and for lack of a Nation project shared by MOST of the Mexicans, Argentines or Latin Americans in general. The day we trust OURSELVES instead of plaguing our weaknesses, but working on them to overcome them WITHOUT COMPLAINING IN PUBLIC TO LOOK FOR THE PASTURE OF OTHERS, another rooster will crow to us. But in the meantime, let's keep ruminating ...

  8. The reason why people are screwed is because they want to be, they only think about their silly lives and how to be more silly, that is not the fault of the teachers but of the useless people who only know how to care about themselves and who also they are all useless, and end up being nothing more than a hindrance for people who really want to make this world a better place, if everyone focused on everyone's future and not just their own, at least there would be fewer problems .
    If you think that I am one of those crazy people who thinks he is perfect, believe me not, but I have come to contemplate humanity hoping to see something that convinces me that they do not deserve to be eradicated from existence but they always end up disappointing, they should think more about that for that there are many who may have that opportunity and if there are those who would take it.
    So I ask please that if whoever reads this is one of those useless people that at least it does not become a hindrance because if it gets in my way I will consume it, I will discard it and I will make sure that it will never hinder someone again.

    If you're wondering who I am, it could be the person sitting next to you in the bus, taxi, school classroom, movie theater, etc. So think about it before you risk it.

  9. Try to clean the sheets well, that they do not have grease from the fingers, and use to try something like a freshly rubbed balloon on your head. If it still doesn't work, make sure the wire is making contact with the plates and the sphere. Greetings

  10. Hello, I am from Uruguay. I appreciate all the blogs that share free information with others, since it is a way that all young people who have an interest in this type of study can access information on the web each time.

    I have a simple doubt, what they call gold leaf, the flakes that they are. Of copper bronze or covered with gold itself? Greetings and forgive my ignorance, they are just different names, capable of a simple Spain paper as they say here or as a golden gift. No idea. I am looking forward to your response. juanjomf97@gmail.com

    Uruguayan I can say that gold leaf is a very thin sheet which must be worked with great care as it breaks into pieces.Therefore, you can buy shellac, which is sold in hardware or artistic stores, you apply it with a brush, place the sheet very carefully and on it you gently stretch it with a soft bristle brush (natural bristle), you also have another option To achieve a similar effect that is called FOLIA, there are gold, silver, bronze, copper, and reds, blues and others and there is a false gold sheet, this is glued with cold glue, it depends on the country so is the material to stick it and it is apply the foil on it and stretch, let it dry and then remove it, the difference it has with the other is that in this one a plastic is removed when pasting and only the gold remains stuck. Look at the places that I put you, it is used a lot for church furniture.
