Burning pencil lead with 24VDC No.1

[patrickjcollett]

0:22 what the fuck is that thing going to the light?

[Galodude]

@rryking it's the light effect on the camera. It's to bright to pick up so it spreads the light out

[rryking]

what is that purple glowing rod thing?

[OK2BCK]

velmi dobre, za ten smrad to stalo?

[BigJuana831]

Ill bet u the lights went out

[1sgtpjwinkels]

well time to go back to school shopping to get more pencils!

[witecracker2]

what the hell flew into the light? what was that?

[VicariousReality7]

@witecracker2 Moth ghost

[witecracker2]

@VicariousReality7 well thank you, cool, didnt even think of it, im so confuse, go towards the light stay away? if when we die where would you go? that moth thing got s me messed up man,,,

[beanfarts]

congradulations you found a nother way to be stupid

[mV33rs]

lots of UV radiation.. like LOTS

[deaftodd]

i think theres clay and wax in there too beside graphite

[pashaahsj]

Lead is the new graphite xD

lolz i wonder why they call it lead anyway haha

[L00NGB00W]

lead pencils were employed before graphite pencils were.

The name pencil 'lead' simply stuck.

[pashaahsj]

well yea that would prolly be the true reason, but the real meaning behind my boiling querry was what is the "lead pencil" ?? =p

thanx for reply and in adv for the next =D

[madjimms]

@L00NGB00W There was lead writing/drawing utensils THOUSANDS of years ago, but nobody has EVER manufactured real lead pencils, that is a myth.

[L00NGB00W]

@madjimms

I suppose I misspoke, that's what I was implying. Thanks. =)

[madjimms]

@L00NGB00W No problem.

[LTUdrak]

nice i like it

[HEXolam]

hele skus dát co nejmenší tuhu já to skoušwl s 0,3 a ta svítí mnohem víc anik sem neviděl že se přehřejvá trafo :D když dám třeba 0,7 tak tuha vybouchne

[TheKenos]

magore

[KarbineKyle]

5/5! Very Nice!

[Lordrizzi]

Realy cool

[gybustudent]

hezkýý :)

[AdamBoozer]

If you look at it closely it looks like a star pretty cool.

[flickeries]

24 volts only! Would make a nifty lamp :]! Set that annoying house mate on fire.

[Benzed92]

You should know how much current they use... its in the title. =)

[CaptainCrunch80]

The title tells about the voltage, not the current.

Graphite has a Resistivity of about 8 Ohm*mm^2/m.

Letzt say their part is 5cm long and has 3 mm^2 (A short piece of a pencil). Makes 0,133 Ohm. What will result in 180 Ampere with 24V.

The power supply surely has a limitation for the current. I think max. 20A. What still is 480 Watts heating power.

[coffeesombi]

@CaptainCrunch80 don't forget that carbon has less resistance the more warm it gets

[hockeynnascar24]

@CaptainCrunch80

in english

[RENOSfinest69]

@CaptainCrunch80

Man, i though that learning about how life started and binary fission, and how chromosomes are made was confusing the hell out of me, you sir just did not make a bit of sense

[Searcheur]

@CaptainCrunch80

oh of course! *hits my head*

[Nuker1337]

No, that's the voltage. The voltage U is a function of the resistance R and the current I by the formula U = R*I or I = U/R.

[paulma8]

how much current did you use?

[panzerkilla]

wouldn't be surprised if you guys die young.

[dregenius]

@panzerkilla Not a problem. At least they won't die bored.

[SAMPMoviesTFS]

kool

[simonstrom15]

WOOW

[TD424]

Tyy vole xD

[xexorz]

Look, Mom!  A shorted arc-lamp.

[withinthetruth]

what the heck is fly into the light from under the desk

[windoes98se]

cool

[coreyaustinmiller]

heyuck heyuck lol who ever laughed should laff b4 they start filming its not funny. just him laffing is.

[SirSkidPlank]

thats cool

[SegaJackNLS]

what was that??

[strikeme5]

lead pencil

[Alkhemista]

graphite* the "lead" from a pencil
