Just a thought ... you require 4 spacers for this project but 3 of them are just used for simple supports in the base. These don't have to be nylon necessarily. The only one that has to be nylon is the one you use to form the upper roller with the rubber band. That one has to be nylon because of where nylon falls in the triboelectric series. The nylon spacers linked in your materials list cost nearly $5 each. You can use something much cheaper for the 3 supports for the round base.
Beautifully built, again. I was really looking forward to this video, because I have built a van-der-Graaff generator myself many years ago. One can even build a n ion motor. You just need some copper wire bent to an s, sharpen the ends, hammer it center and punch a little little dent with a prich punch in the middle and make a stand from another copper wire that is an o at the base to rest on the sphere and a vertical axis, which is sharpend to fit into the punch hole of the s. After is is ballanced, it will spin, when the van-der-Graaf generator is running, because the ions in teh air will repell the sharp ends of the s.
Thanks Chad. I'm a perfectionist and incorporate that mentality into my builds. I actually value neatness and appearance as much as function when it comes to a build...if my build looks messy or disproportionate, but performs really well, it bothers me. Just a preference of mine. Really appreciate the compliment!
I actually noticed something strange happening. At 0:36 I observed that your face and hand seems little bit red and sunburnt. But at 0:40 your face and everything seems normal again. Maybe it's something with exposure and saturation, maybe it's the lighting conditions. But hey, I didn't notice anything until I read your comment. You look normal 😃
What's funny, is i began this project before electroboom put his video out. Then i put my video on hold, and King of Random did a Van Der Graaff video, so I figured I'd finish up this one and not look like a copycat!
@@PlasmaChannel King of random video was pathetic really, he really had no idea what he was talking about and probably caused more confusion than anything. but that seems to be the way with that channel of late. Its channels like yours that show the rest how its really done.
I agree. TKOR didn’t know much about VDG. I mean, he thought gallium had something to do with the decreased shocks. I was like, hello? That’s the basic function of a lighting rod. It’s bleeding off electrons reducing the spark potential. It had nothing to do with the type of metal. It was just a pointy object. And that’s why you want no sharp points on the sphere as stated in this video.
Heads up Plasmanauts! This DIY build will be available as a kit on Plasma Channel's new website. After receiving numerous requests, after several of my DIY videos, its about time I offer Kits. The kits are ways out, but on the horizon! Have begun building PlasmaChannelGlobal (name may change)
the whole kit to build this little wonder is about to be on sale, correct? Could you please add some fine references, not "too simplified", to understand how it works?
This is simply the best diy Van-de-graff generator video available on TH-cam. And I must say that quality of your videos has improved a lot. I mean your previous videos are awesome but now you produce extremely awesome content. I can't say keep it up because you're already doing awesome work.
@@PlasmaChannel when are you offering it as a kit on your website? i previously tried to email you about it, but got no response, i need a kit, bcus when i start to fool aroun myself i end up with a whole lotta nothing😅
I love it! I have made several of these, they are so fun! My best one is about 3 feet tall, and it produces around 5-6 inch sparks! High voltage is amazing! And I love your videos, keep up the great work!
Try connecting a small pointed bulb (like for a fridge) as the top load to the 3v tesla coil. The entire bulb glows green since the electrons have enough momentum traveling off the long ends that hold the filament to excite the oxygen in the bulb to a higher energy state where they decay and release a green photon. It's pretty much the Northern Lights in a light bulb! Also I connected a pin of a 1" vacuum tube as the top load and it shoots out 4 inch plus sparks off all the metal pins. I guess the electricity has less resistance and gains higher speeds traveling through the tube and then is launched off the pins. The sparks are very, very dim but to get a 4" spark from 3v tesla coil is awesome!
I can't help but notice that this looks very well designed - almost like a kit. The steps were really nicely laid out too. If I had to offer one criticism, you glossed over the upper brush design quickly and I never got a very good look at it. Still, I enjoyed the video. So... thanks.
Thanks so much for compliments and suggestion! I really took my time making this video, and filmed it in a 40 degree garage...so knowing you appreciate it warms my heart...even if my body is still numb.
About 60 years ago I built one using a plastic pill bottle for the column, an aluminum salt shaker for the dome and an old metal recipe card box to house the motor. It was very crude by comparison to yours but it worked. This was featured in a magazine but I don't remember which one.
Very nice! The acrylic column is wide enough that you should be able to get this to work with a much wider rubber band. You could double or triple the output!
Question! Does it matter what material rubber band? You used what looked like a natural latex rubber band. Could it be a synthetic rubber belt? For durability and scaling perhaps? It seems materials matter like the must be nylon spacers.
Some people have the brushes drag down on the belt. It will still work but then belt gets torn up really quickly. Also, then metal atoms get spread across the out of the belt and over time the belt becomes more conductive (bad). Yeah, brushes ideally should never touch
Ok, so I know that you don’t want any jagged edges for this type of build in order to avoid voltage leakage, however, if you place two poles with jagged edges each, the voltage leakage will create an even greater iconic wind/thrust between the poles.
I still have a Wimshurst machine I got back in the 70's from a company that used to be called Edmund Scientific. The device is powered by hand with a small crank. It would deliver a one inch spark, but can do nothing now since I need new brushes and a Leyden Jar. I still want to find a way to power it using a small motor with enough torque. I think Edmund Scientific is called "Scientifics Unlimited" now.
I really appreciate such kind words. I like to build things with high quality so that they last forever, and, like to shoot as high of quality as possible! You can help with the subs by sharing my content on social media.
Awesome Build mate, you really do have a way of presenting these projects in a way that's interesting and engaging, keep these videos coming, as need all the inspiration i can get to follow your lead.
And do you know how i can calculate how thick the wire of the secondary coil in a tesla coil has to be? Or is one thickness functioning for every tesla coil?
Why is a grounding brush required? Would that not just cause all the static electricity to go straight into the ground, preventing charge build-up and defeating the purpose of the generator?
Hey, I'm thinking about building this but giving it a 12 volt 9000rpm motor, 3 18650 3.7 volt batteries and a regulator and a turnable switch so i can adjust the speed and power would that work?
I'm in Europe (the Netherlands), and getting the supplies from your list shipped to here is going to be so expensive. The only option for me to build the Mini Van De Graaff (Note the name without the *R* ) is by searching for the needed stuff here in the Netherlands. *Fun fact. Van de Graaff is a Dutch name. His father was of Dutch descent*
So, you used two teflon rollers and a rubber band? The upper and lower rollers are teflon and the rubber band transferring charges back and forth and the collecting combs remove the charges from the rubber band?
I have tried to make most your DIYs but this one worked the best XD but your nylon spacer link didnt work so i used glass and it made 1 1/2 to 2 inch painless sparks
Great video except I did get a little confused and had two questions: 1.where did you get your switch from 2.where do the wires from the batteries connect too It would help so much thank you
Hey, not sure if you'll reply since this is an older video, is it possible to use more readily available materials instead of the Nylon spacers and Teflon bar? Having a hard time finding them in Egypt so it would be nice to know if there's something else I can use. Thanks.
he tries to make it sound so simple, when he's used to building stuff like this all the time. LOL To me it would probably take me a week, with me constantly cussing a blue streak and getting stuff wrong and having to redo it! LOL
You emphasized that nylon spacers are important, but you never explained WHY? I'm going to attempt a 3D printed version for all the plastic parts. What effect would using other than nylon have? Really interesting project, and very well executed.
@@PlasmaChannel I was asking about the 4 nylon spacers. I thought I might print them, but looks like I better stick with nylon there. I understood that the roller would have to be teflon. I have the 4" disks and the tower drawn. I'm going to draw up a mount for the motor as well. And look up triboelectric series :) Thanks for the reply.
Very clean build! After using crt tv combs with success I'm starting to wonder if the whole idea that electron carriers is not to actually spray electrons but actually think of them in terms of charge density. If the roller passes through a dense field the tribute electric effect will draw from that region first. Once drawn it is then replenished due to the draw of charge vacancy (effectively positive charge). Also interested in watching Walter Lewin lectures of 8.02x the biggest determining factor of charge that a vandagriff can store is determined by the the surface area of your gaussian sphere minus any imperfections where charge density may rise to the point where it breaks down to the air.
@@maxprophet2401 What year were your TVs from? I grabbed mine from the 3 CRTs found within a rearprojection TV (just barely pre flat screens). CRTs can build up a ton of static, I assumed thats what they were for.
I know what you're talking about now, I was thinking they were for grounding excessive static so my guessing may be as good as your assumption, thanks!
@@maxprophet2401 Exactly what I am betting. And they seem to do pretty okay with my VDG generator. Which makes me think that geometry of the conductor plays a role in terms of charge density and having triboelectric action (friction passing charge) happen within it opens the door for perhaps improvement on the designs.
I know this video is old, but hoping someone can help. First off, thanks for this video! I am trying to build it with my son. Is the spliced wire, from any electrical wire, something specific? Any tips/advice on cutting the metal sphere?
Hi, honored you're trying to build this with your son. So, the spliced wire source is not important. You can use even metal screening. The point is to have a bunch of sharp metal points close to the rubber belt. Note: close, not touching. For these little generators, i found that braided wire was a quick and easy solution is all. My larger Van Der Graaff video - I used metal screening and the results are amazing. Cutting the metal sphere was -admittedly- sketchy. I had to use a circular bit, and, nearly cut my hand doing so. Be slow. Be careful. Use a 1" ( I think 1"?) bit.
Cool video, nice work on explaining how to build this. I only have one doubt. Isn’t the grounding brush supposed to be connected to the ground? What’s the physics behind this?
Thanks for the compliment! So, i personally hate using solid ground connections. It makes a device totally dependent on a physical connection. A way around that is to place a counterpoise on the base. While counterpoises only work for AC, they do act as a capacitor with the ground, and allow for a mild transfer of energy between ground and device. This generator uses a counterpoise on the base....that almost touches the surface it sits one. So, it does, in effect, have a weak ground connection.
I would suggest you look up 'triboelectric series' on google. This will explain why nylon is very important. You may receive results with other plastic....but you may not. Please consult the triboelectric series for why.
Bying all those parts is getting expensive, especially if you have to pay shipping for everything. Also, living a small town, not everything is available: the last time I couldn’t find any store for a 5cm diameter plastic pipe… I know it’s crazy! I’d love if someone would kickstart/etsy/ebay some "kits" for 1 generator (a bit like that amazing Sparkit)…
I like how you can see the burn spot on his thumb where he's been arcing the tesla coil
I just admire that fact that your constructions are so very neat and tidy... They don't just function well, they look beautiful...
Thank you. I place equal value on aesthetics, as I do performance. One without the other cannot exist. That is my personal belief

After is is ballanced, it will spin, when the van-der-Graaf generator is running, because the ions in teh air will repell the sharp ends of the s.
That’s true. Ion motors are fun. Thanks for the compliment
I like the idea of having a collection of mini high voltage devices like this. Keep it up! thx
I just love how presentable all his project are. I can probably make this but it wouldn't be as decent looking as this.
Thanks Chad. I'm a perfectionist and incorporate that mentality into my builds.

Just a preference of mine. Really appreciate the compliment!
Jay. You are by far the most neatest hobbyist I've ever seen.

Okay this is driving me mad. Does my skin appear really red and sunburned to you viewers? When I uploaded to youtube, my skin tone was not that red.
Maybe encoding issue
Not excessively. You do look exposed to sun tho.

If you inject ions at the base you can get these to go to way higher voltages.

Hey, as long as you watch it. Bonus points if you watch it while eating Detroit style pizza.
Yes thank you sir i have been waiting ever since your last couple video for this one.
Question!
Does it matter what material rubber band?
You used what looked like a natural latex rubber band.
Could it be a synthetic rubber belt?
For durability and scaling perhaps?
It seems materials matter like the must be nylon spacers.
Buy a small HV generator that creates some 10-20kV and connect it from ground to the lower brush. This is a real boost.
Cool, and I only have to replace the rubber bands over time. The batteries are forever.
Why would the batteries be forever?
Congratulations to the feature on HackaDay!
Thanks! I love working with HackaDay. Love those people
Well this has cleared up 1 mystery, I always thought the brushes had to touch the belt for it to work, now I see that they don't.

Jey, I need a vedio about high voltage devices that can be used in mini battery powered tesla coil.
Plasma Channel.......You can also use a VDG as the power source for a tesla coil.
If you could possibly get the process to work in reverse like reverse the polarity and have it suck instead of push electricity
I ended up building a voltage multiplier, inspired in part by your mini arc lighter lightning tower.
This is nice, but is it just for entertainment?? Can you build an energy device that can actually be used for home electricity needs??

Thanks for the compliment! So, i personally hate using solid ground connections. It makes a device totally dependent on a physical connection. A way around that is to place a counterpoise on the base. While counterpoises only work for AC, they do act as a capacitor with the ground, and allow for a mild transfer of energy between ground and device. This generator uses a counterpoise on the base....that almost touches the surface it sits one. So, it does, in effect, have a weak ground connection.
Any idea what size that rubber band is? There is a baffling selection of sizes on amazon.
WHY SHOULD WE USE NYLONE? Can't i use plastic parts instead of Nylone ones?
I would suggest you look up 'triboelectric series' on google. This will explain why nylon is very important. You may receive results with other plastic....but you may not. Please consult the triboelectric series for why.
I love these projects.
They are really fun. Building big is always fun, but not convenient. I love minis!
Hi, may I know if this also cause my hair to stand ?
I'm looking for a circuit that will zap mosquitoes when they get close...
When van de graaf works at wether it works vere power ful and good
Just wondering, can I replace the Teflon bar with a wooden bar?
Very very neat work
Bying all those parts is getting expensive, especially if you have to pay shipping for everything. Also, living a small town, not everything is available: the last time I couldn’t find any store for a 5cm diameter plastic pipe… I know it’s crazy!
I’d love if someone would kickstart/etsy/ebay some "kits" for 1 generator (a bit like that amazing Sparkit)…
I had been dreaming about you man.!
You flatter me haha
is there any way to make a spark with a 9v battery and make it compact like being in ur pocket?If there is will u plaese make a video about it?
Hi again, what would be the intended purpose of this device?
