  • LIKE/FAV for Paper Goodness! Can I borrow your pencil? Music Below:
    Here are the items you will need.
    1. A number 2 pencil (Better if you get a 2B pencil from the art store)
    2. A thick piece of paper
    3. A single LED
    Graphite is a pretty terrible electric conductor but it works well enough to do some cool stuff with paper.
    We can actually make a fully working circuit as well as a flashlight using the 3 items above. Check it out and let
    us know what you think!

    The confusion with lead and graphite is, for many years Lead has been used before in pencil. But they were removed and changed to graphite, mainly because lead is very poisonous and harmful to the human body.
    People, lead is a type of metal, and graphite is carbon (like diamond). The reason we still call it lead is because the name is stuck as a trademark to pencils. Just go with the flow.

    Reminds me of my overclocking days when some pencil marks on a AMD Athlon XP would unlock it (IIRC), and some marks on the new $550 video card along with the Vaseline on the top side so when the TEC got to cold and made it frost up on top or the phase change cooling on the cpu dripped condensation on it it wouldn't fry it.
    In jail pencils can be used by sticking a wire in the electric outlet and touching the pencil across to light cigarettes and stuff but you had to be careful to make sure there was enough resistance or it would blow the breaker on the TV and the guard would have to reset it

      @munchmafuziquchi2965 8 лет назад +2

      You could make a 50::50 voltage divider with two input terminals. If only one of the inputs is high, then the signal output is 50% of V(source). If both inputs are low, signal out is GND. If both inputs are high, signal out is V(source). With the proper amount of amplification and attenuation to accentuate the difference, you have a resistive "and" gate.

Of course my next thought was "wait.. does that mean you can make a circuit board on paper??" and youtube has provided in satiating my curiosity.
    As an artist I'm happy to see that the experimenter used good artist graphite to conduct their experiment.

    The use of a graphite pencil is interesting since the material is conductive, it would be necessary to test, I do not know if I have already done it, what difference is there in using B 2b 3b 4b there are perhaps conductive differences and they could be seen instead of using a led use a tester or multimeter and see how the values vary another option that occurs to me is to use the old carbon paper which is based on graphite which stains the fingers when touched, the new ones do not work because they are not based on graphics and use binder

    I know that electric motor contacts are made of graphite. I have several graphite rods found near an abandoned smelter. I want to make a switch that can carry alot of current without contact welding the switch which results in a runaway closed circuit. Bad. I could probably get the same results from a fat piece of lead or brass. But graphite is also a lubricant and may work better if it doesn't cut current like a resistor.

    There is metal in the pencil. If you notice, it reflects when you paint a part with a pencil. Metals also reflect. The metal also transmits kwlem for electrical conduction.

      Ice Wizard glass also reflects doesnt make it a metal...
      Of course it does contain metal but your explanation to why it does makes no sense.

    I tried to do the sane things several times: I got the resistance of this "graphite-on-paper" nearly several MegaOhms per inch (width nearly 0.05 inch)!!! It was absolute impossible to light a led or do any other useful things with it.

    if you dont have LED or other light bulb and are NOT working near easily flammable stuff you can use a short piece of the pencil/graphite as a light bulb itself, or a fire starter for that matter if you touch it with a stick.

    Here's the thing! When you draw a line with your graphite pencil you are depositing carbon on paper. Carbon is present in resistors. And if you are drawing thin lines, you are essentially "Drawing" a resistor. :) But if you make the lines thicker, you are drawing a conductor (with a pretty high resistance though). But I guess the resistance will decrease once you make it thick enough!!
