Van De Graaff Generator Not Tesla Coil

[Resonanttheme]

Polycarbonate then

[Resonanttheme]

"Spark tube is a 1 1/4" clear plastic tube"

What thickness and what kind of plastic is it? Nice effect.

[subhankar5584]

For fruitful information about Van De Gruff Generator this video will work.

I just wonder why NASA does not develop

a safe source of energy such as this one here and get rid of all these toxics from our life

It is all described in the

top magnetic generator

search for it in Google

[FizicksTeacher]

What is your discharge wand made of. It appears to be just a grounded rod with a 1" diameter metal sphere on the end, inside a plastic tube. I tried recreating it with similar materials but did not get anything like your discharges. Could you tell me what I was missing if anything.

[PlasmaStar9]

Discharge wand was a cabinet knob with a small brass rod screwed into the threaded hole to keep the knob pointed forward. Ground wire clips to back of rod. The tube itself is one of those cheap clear plastic tubes that fit over a fluorescent bulb. The problem is that static electricity is very persnickity. Sometimes it works. Sometimes it doesn't. Could be variations in humidity.The tube tends to build up a charge like a capacitor. Try different knobs, distances from tube to terminal, etc.

[FizicksTeacher]

@PlasmaStar9 Thank you for your response. I will change a few things around. Very nice arcs!

[2012thedevil]

hey man you should add a water capacitor to get longer THICKER and LOUDER arcs. Costs10 bucks or less and is suuuuuuppppeeerrrrrr easy to build. I have yet to see anyone do it.

[jtomshine]

Can you comment about what materials were used in the belt & for the pulleys? This looks like a particularly successful Van de Graaff generator, so I'm curious exactly how you did it. Suppliers & part numbers would be greatly appreciated!

[PlasmaStar9]

bottom pulley is1" dia nylon bar stock. the top pulley is 1" dia teflon bar stock. the belt is 1/16" thk black solid neoprene rubber from an industrial rubber supply company.

[jtomshine]

From Grainger? I've seen that they carry those materials as bar-stock, but at the moment I haven't got access to a lathe -- the only way I can think of to put a hole through the roller properly. Did you think up a clever way to get a concentric hole through the bar, or did you have a lathe handy?

[PlasmaStar9]

Don't know about Grainger. Actually bought bar stock from a retail plastics supply co like the kind that sells sheet plexiglass. I do have a lathe which I used to machine the top roller for ball bearings and the bottom one for the motor shaft and to crown the rollers slightly. Yeah, you pretty much have to have good concentricity, because the faster you can run the belt, the higher the output. I mounted the bottom roller directly on an upright vacuum cleaner motor for power and speed.

[aajuliosomaa]

ei correia de camara dear funsiona ?

[HybridWaterMan2]

Wow! Really well done- very nice generator that puts out respectable sparks for sure!

[tikifish28]

Hey, me again I've gotten some generators really going now, up to 6 in. i know not as great as yours , but I'm still working on it, I was wondering about your sphere, how did you cut a hole into it? or is it just resting on top of the tube there? also the neoprene belt that you use is it a rubber almost foamy material that is glued or is it a true rubber? thanks, any other tips would be great!

[PlasmaStar9]

To cut the hole in the ball I drilled a 1/4" hole then used a jigsaw with a fine tooth blade(32 teeth per inch I think). Then used a 3" grinding wheel and fine sandpaper to round it out. The belt is black 1/16" solid neoprene rubber from an industrial supply place. It looks and feels like bicycle inner tube, (but innertube didn't work when I tried it). Nitrile, white neoprene, and some other surplus rubber didn't work.  Latex worked if run real fast.

[tikifish28]

@PlasmaStar9 Thank you I have some stainless steel bowls from IKEA that are prefect but I want to make the first attempt at cutting it to be right

[MrHacker3000]

its a light saber!!!!!!!!!!

[coldarc]

@MrHacker3000 no a light saber is made of light repelling light in a beam.

the repulsion is caused by a vector alignment of two light waves at slightly

different frequencies their waves repels when the two waves become out of phase.

imagine two sine waves at the top of each other on a scope when one sine wave

pattern change wave lenght the two waves face each others northpole against each other and they repel. electromagnetic waves moves in 3 dimensions.

[MrHacker3000]

@coldarc

LOL thanx 4 all of that super nice info. but what I did says before was a sarcasm hahaha :)

[hangoutsumtime]

where did you get the steel ball

[PlasmaStar9]

It's a stainless steel gazing ball available from on line garden centers and ebay

[bige5230]

Very cool video, I made a Van de Graaff as well. Check it out on my page and tell me what you think. I really like the spark tube. What did you use for the metal part of the handle inside of the tube?

[laurietorie24681]

does the atmosphere effect the voltage shocks and stuff? because i live in trinidad and i wanna build one. will it work well in our atmosphere?

[PlasmaStar9]

Humidity tends to lower the output, but I live near the coast where the humidity is high all the time and as you can see it works pretty well.

[laurietorie24681]

I am also in eighth grade a building a Van De Graff Generator but i am not sure how to do it quite yet :)

[PlasmaStar9]

I used teflon upper roller. Nylon lower roller. Neoprene rubber belt. Difficult to say what works well without trying it. Grounded lower brush to the ground prong of the electrical outlet. You can also ground it to metal water pipe or a rod stuck in the ground. The faster the belt runs the higher the output. Speed is important.

[diggarazer]

heess like a southernerlol

amm gonnn kick yo ass iiiff yuuu dunt gittt uff maaa proppertyyyyyy

[EPhantom125]

Can you please post some design specs, or schematics of some kind please?

[cprich22]

how much is it generating coz the one at school generated 600,000 volts and onlyjumped 7cm so this must be generating a realy high voltage

[longdistance50cal]

well if it was only 7 cm you didnt let it generate ling enough. it has a 600000 volt potential, but it probably takes 45 seconds to a minute and a half to get that high. after about a minute you should feel the static at about 3 feet away.

[guydie5]

you must not of heard in the video he said it was around 700,000. but the reason yours at scool was not is probably because the were not using the spark tube

[fourboxers]

Thanks for the info. I will make one!

[fourboxers]

Great VDG, thanks for sharing all the info to questions. I read all the other texts and didn't see the answer. How did you make your discharge wand? Very snappy! Thanks.

[PlasmaStar9]

Spark tube is a 1 1/4" clear plastic tube with a brass cabinet knob mounted on a brass rod which is grounded. The knob/rod assembly slides inside the tube for adjustment.

[longdistance50cal]

all you really need is a ball of aluminum foil attatched to some wire that goes to ground. run that through some pvc pipe and you have one. i like this guys better though. you can see the sparks

[firedude201234]

care to explain your shitty comment a bit better?

[tikifish28]

Plasma star I was hoping that you could look at my new and improved van de graaff generator it is called " van de graaff generator 2 "

[SciVoltage]

Great video!

Thanks!!!

[metalini]

u can get high voltage from a van de graff generator?!

[ThrowMidgets]

Ya that is pretty much the purpose of a van de graff

high voltage, low amperage

[Marron077]

if u play frm 12 sec it siunds like hes sayin lick ur balls!!

[tikifish28]

what did you use for both top and bottom rollors?

[PlasmaStar9]

What give away all my secrets? Top is teflon. Bottom is nylon.

[tikifish28]

sorry i didn't want to ruin your vdg just wanted some help on my own.

[PlasmaStar9]

just messing with ya. ask away. I can always respect a person trying to accomlish something...

[tikifish28]

ok, another question about the rollers, is did you use teflon and nylon tape or plastic rollers?

[PlasmaStar9]

I used 1" diameter solid nylon and teflon bar stock for both.

[tikifish28]

Sorry to keep bothering you about you rollers, but were could I buy the nylon and teflon bar stock that you used?

[PlasmaStar9]

Ebay maybe easiest. For Teflon search PTFE ROD which is the generic term for Teflon. Nylon, which is cheaper, is actually more difficult. Search Nylon Round Rod. May have to go into Ebay stores and look. Also from yellow pages, industrial plastic suppliers in your area usually carry both. 1" dia is not magic--use 7/8 or 1 1/8 or 1 1/4 if that's what they have.

[tikifish28]

Look at my vdg i have posted its called homemade van de graaff generator. I took your advice

[TCDIL95]

where did you get your belt?

[PlasmaStar9]

2" wide X 1/16" thick black industrial grade neoprene rubber with the ends superglued together on a 30 degree angle.

[TCDIL95]

ok.

thanks!

[cathaloma]

That was pretty cool, man

[pasleyt]

mines about 250,000 volts. static that is.

[cribcat1]

Nice!

[triplethreat40]

hi i'm working on how to adapt a tessla coil or van de graaf generator for stage magic purposes. any help?

[jman51]

Wow excellent work! I'm currently working on a 5 foot model using two rimless bowls welded together, and an ion generator. I'm having a bit of trouble with my brushes. What are you using?

[PlasmaStar9]

cut sections of fine copper stranded wire out of an old electric cord and solder them onto a piece of #12 or 14 solid copper wire.

[Ogaitnas900]

You talk like jack nicholson lol. great vid , thx

[Maanhtje]

Wauw die is mooi! Ik heb er ooit zo eentje gezien in zo'n tv-kindershow. Mooi man. Is het moeilijk om te maken?

[Arexux]

Very fine VDG.

This unit is certainly more powerful than maney comercial units. The type found in schools etc.

And shows gluing together your own band is not inferior to buying a commercial one.

[Neumus]

the sphere and the belt, how do you make them?

[PlasmaStar9]

The sphere is a 12" stainless gazing ball. Hole is cut with a fine tooth jig saw. The belt is 2" wide X 1/16" neoprene strip. The ends are glued together with superglue.

[guitar87tommy]

HOW DO U MAKE 1

[Ex0th3rm1c]

great video

awesome explanations

5 stars

[guitar87tommy]

Great job man

[hydromaverick]

perfect demo. thanks for all the data.

really well done!

[FoxRed13]

You should have been less scientificy and more hand-touchy shocky-hair-standupy~

[ikarus314]

blah, blah, blah, blaaaaaaah, blah, blah, blah, blaaaaaaah

but AWESOME video, nice generator...

[jonwallace1]

lame... not another fucking tesla coil

[SKarmytech]

this aint a tesla coil bitch

[stapleachip]

fantastic job! what did you use for the band? and the rollers? i built one myself, a small one using 2 icecream scoops for the globe, the sparks were very small but it was powerfull enough to screw up my keyboard 4 feet away. again, great build!

[PurePower025]

your style of talk was putting to sleep.

but other than that, great video.

[PurePower025]

goooood show

[xFYCNxcps22]

you sound like the captain on a airplane

[VideoJunkei]

please return your seat to an upright position :*)

[friedrichsacher]

Thank you very much! I have the same Idea earlier but I think that these balls cannot work! But now I know, that these balls work!

[friedrichsacher]

Where are the Steelball from???

[PlasmaStar9]

They are 12" stainless steel gazing balls (yard decoration) These came from Outdoor Decor on the internet.

[JELLYLEGS123]

good job!

[diegonikki]

i see the sparks and its big

[tiver62]

I think VG is just good for static charge accelerator. what else good

[pontolones]

whats with hicks and tesla coils? you narrated this into a microphone like it was some sort of sporting event, wtf?

[segarza]

If you think that's bad, try running a Tesla coil near electronic devices. I blew out a brand new shortwave radio that way because I left it in the same room about 12 ft away. Nice machine!

[knt3119]

VDGs are fun but the electromagnetic field produced can damage nearby electronics. I found out the hard way with my home stereo. Mine throws 10-12" sparks

[PlasmaStar9]

Ah, yes. You're acquainted with the EMP (electro magnetic pulse)--destroys all electrical systems within the blast radius. But it's our only weapon against the machines....After my digital alarm clock & cordless phone blew up I started grounding my discharge wands to the water pipes.

[youtuubbguy66]

Thanks for the tip!

[teslaspigeon]

this is very impressive home project i would like to build one with my son could you do an explanation of your construction i would be very grateful

[PlasmaStar9]

Tried to do a detailed desc. It's too long to post. Tried to do a really short version. It's too long to post. Lots of web sites with detailed construction info and Howto videos on Youtube. Otherwise wait for my howto video which I hadn't planned to do. Or buy a kit and use it as a springboard. Thanks.

[gt4awd]

Nice VDG, did you make it? Looks premade to me, but thats just because it looks really well constructed. Someone needs to make one that uses the water method and normal belt driven combined into one. That would be interesting. Link in my favorite videos if you dont know what I am talking about. Video is entitled, "A type of Battery".

[mikeandtiff]

now if that is home made, then hands down.. very nice machine. Not sure my machine can produce an arc like that! it is featured here on youtube. Thnks for posting
