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?
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 😃
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.
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.
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😅
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 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.
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!
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.
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.
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!
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
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!
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.
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.
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?
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?
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.
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
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.
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*
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
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?
Yes, you need the top roller to rotate. Otherwise, it just wears down the rubber band super quick. The triboelectric effect does not need rubbing. It just needs contact.
Top roller is connected to steel bowl but bottom brush is connected to which ? Actually I am also construct this thing similar to you but not working Charge is not obtained
Kalyan Karri the top roller is not connected to anything. It rolls around the rail. The upper brush is designed to be placed 2-4 mm away from the rubber band, just above the roller. The upper brush is what’s connected to the sphere up to. The bottom brush also does not touch the rubber band, and is connected to the counterpoise.
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.
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.
You can also use a black bicycle inner tube. Cut the rubber to the appropriate size & glue the ends together to form a circle.. You can also make an enlarged VDG generator with an inner tube without having to spend a lot for a band.
@@dandruff7807 I did that with the first Van de Graaff I made couldn't get it to work and ended up using the stretchy bands from a head work light and always had trouble with the Florida humidity
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 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 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
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 have a question that I really need to be answered. I bought all of the pieces linked in the video, but the motor is a bit odd, it has a shaft at the end and I can't seem to get it off. how did you do it?
The shaft does come off.....but takes a bit of work. One of the 5 motors I bought....got ruined when I tried to remove the shaft. So be careful....but also be very forceful.

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.
Absolutely stunning build quality as always Jay. Amazing. Keep up the great work.
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 😃
Not too bad
I didn't think anything of it. Looks fine to me. Maybe turn up the iso on your camera to get a less contrasting image.
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
Jay. You are by far the most neatest hobbyist I've ever seen.

Yes thank you sir i have been waiting ever since your last couple video for this one.
Buy a small HV generator that creates some 10-20kV and connect it from ground to the lower brush. This is a real boost.
Simple and the best, I will teach it for my high school student... thanks bro for your sharing...
Thank you for your kind words! Please, do use it for education.

I really want to build a mini Pelletron.
Nice , very clean design. Thank Jay.
Would a hair band or some kind of stretchy cloth work better then rubber
The problem with a hair band is that it's not flat. You need a flat band like structure to carry the charge. Cloth can indeed work
A Nylon panty would work better but it doesnt hold very long
You can also use a black bicycle inner tube. Cut the rubber to the appropriate size & glue the ends together to form a circle.. You can also make an enlarged VDG generator with an inner tube without having to spend a lot for a band.

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).

YIPPPPPPEEEEEEEE NEW VIDEO FROM "PLASMA CHANNEL" 😃😆😀🤗
Love seeing you comment on my video Tarun!
Just wondering, can I replace the Teflon bar with a wooden bar?
Where can i find the rubber band because i don t have one
Staples is a good place
So are the kits available yet?
If you could possibly get the process to work in reverse like reverse the polarity and have it suck instead of push electricity
would the top roller rotate or be stationary?
I have a question that I really need to be answered. I bought all of the pieces linked in the video, but the motor is a bit odd, it has a shaft at the end and I can't seem to get it off. how did you do it?
The shaft does come off.....but takes a bit of work. One of the 5 motors I bought....got ruined when I tried to remove the shaft. So be careful....but also be very forceful.
Thank you so much! I really like your video.
How much voltage 🎉 1:23
es tut mir leid, dass ich dies nicht verstande habe
How many revolutions per minute does the 3v motor you use have?
I 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
Maybe this helps
can i use electrical tape?
Just wondering what adhesive you used to join the acrylic?
I used Epoxy.
I ended up building a voltage multiplier, inspired in part by your mini arc lighter lightning tower.
You should make this a kit.
