I show you how to build a fairly simple geodesic dome out of rolled-up paper. This dome is a 2 frequency dome, commonly seen on playgrounds. The principles shown with paper can be transferred to other materials, but paper is cheap and quick to demonstrate with. With a thick enough roll, it has significant strength.
Very useful, thank you.
Cool
yes very useful. Now chris can make a dome for his train
Now he is able to make a rainforest geodesic dome for his 100m diy lego train track
uesd
Yep
Thank you very much, greetings from southern Brazil!!!
BRILLIANT ! THE VERY BEST OF MODEL CONSTRUCTION DEMO ! THANKS !
Fantastic video. Excellent explanation. Thank you for sharing your knowledge.
Very clear and well-presented. Thank you very much
Thank you so much!
My ideas are just flowing!!!
🙏
Excellent! Thanks for sequence.
YOU DID A GOOD JOB THANK VERY MUCH FOR SHARING
wow really thank u 😊😊 creative idea 👏👏 will try to made it 🙌🙌
Thanks Mike, very inspiring
Great tutorial! Thank you so much!!
Tis' a gift to be simple!
Very nice, thanks for the video !
Just fantastic !
Merci continue comme ça je regarde toute tes vidéo thanks you si much ❤❤❤
roll parallel tube and then cover it with a diagonal wrap for ease of tape and more strength.
And... you just got another subscriber! YAY!
Well Hey, How about that?! Thanks!
Helped me with my Bronze Engineering Cadets award thing, thanks :)
That's so cool!
Great Mike! Thanks for the share (-;
Thank u very Mach
If you worked A & B different colors clarification best thanks
Great
2021 Bump ... Nice project ... will try and get my kid to do it ...she is 13
Hey Mike,
Is there a relation between the lenghts of the big and small pipes? Or can i just go with 1m for A and cut "a bit" off for B ?
Hey Bartsons, yes there is a relation between the two. It's based heavily in geodesic math, and that's why I suggest using that strut length calculator, because it does all the hard work for you. Just cutting a bit off won't quite give you the shape you need, and I've never tried to do it, because there's no real good reason to be less than perfect. Thanks for asking and watching.
How did you determine the length of the B pieces ?
Good afternoon i build a 2v geodesic dome out of pvc we talked about covering it i have a question its about a wooden 2v geodesic dome which i have Learned it is easier to cover them im wanting to know how do I find the bevel angles that run the length of the struts alot of the on line calculator tell the end miter cuts but I can't find the bevel angles can you help thanks for sharing your experience
Great job I built a dome out of pvc using your instructions and the dome turned on Great I have one problem how to cover it I tried tarps not a good look I tried again with plastic sheeting works better but still looks bad any advice on the subject would be greatly appreciated thanks for sharing and help please
Yeah, umm... domes are really hard to cover. They almost require a custom covering with each gore sewn to match. However, old round parachutes work fairly well. Thanks for watching! glad it helped.
so smart
Great dome demo and explanation!!
Could you give me some guidelines to how to estimate (ideally calculate more precisely) the strength of a dome?
Obviously there're many more factors like material, thickness, beam shape etc... but even generic guidelines will be appreciated!
Thanks! :)
Hey there! I'm actually working on an Excel spreadsheet to go with this that'll calculate all that for you, but it'll be a while before it's done. In the meantime, Google "strength of geodesic domes" or similar, and you'll find there are some decent resources out there. It's really just a lot of trig, and that's why the Excel will be nice.
@@MikesInventions Did you complete this excel sheet? I would be very interested
I am also interested. Did you complete the excel?
Would this hold up with a sheet over top of it I am building a parade float that is going to look like an uprooted tree instead of a tree it is going to be a field goal post but I want to put a sheet over top with roots like a tree drawn on it?
Andrew Ireland, yes it will certainly hold a sheet. Neat idea!
Thank you
I used to love my dome chair
I know i'm late here but...i'm a little confused on the part where @6:11 he says the first ring connect longs but step 5 shows connect it 10B's which are small??
What are the materials used
any website that you recommend to calculate small scale dome? I seen some but how to do it in inches
Hey! The units don’t matter. Just keep the units consistent. All that matters is the ratio of the lengths. Desertdomes.com is the online calc I recommend. It goes both ways. Thanks for watching.
Hey mike I was just wondering how long is your dowel rod im looking into purchasing it
It was as long as it needed to be, and Maybe that was 18", definitely not more than 24". Thanks for watching!
You should have used an awl to make the holes. Other than that, cool project for kids on a rainy day.
can pls tell the measurements u have used for both pls
Hi Mr. Teddy: This little dome's struts are about 11" long, and the other ones are 88.3% of that.
Hi ,,,, because it’s 2V. you put strut A in the first ring ? Pls tell me how you decide to put type A. or A with B ,,, by the way your videos is so good and easy way to understand…,
I put them in the order shown to make the dome come out right. Yes, this is because it's a 2 frequency dome. Thanks, glad it's easy to understand.
Please build dome for 4v and 6v
Umm hey Mike, I wanted to make a huge dome (4 people worth shelter) with 'cardboard tubes' (the ones that are the core of huge printing paper rolls)... What do you suggest , how do I go about it, especially with the joinery?
Hey Purva, I'd suggest either flattening the ends of the tubes and drilling them, and connecting them with bolts or something similar. You could also cut one end of your tube into a short flap that bends away from the tube, then make a hole in the flap and attach them that way. You could also cut short strips of something rigid, yet bendable, that you can insert inside the ends of the tubes then drill the ends of the strips and bolt together and then bend to the proper angles. This method allows you to make the complex angles automatically as you form your dome. It's also possible to tie ropes together and fish them through the tubes, when pulled tight and tied off, they allow your tubes to remain rigid. There are many ways, as you can see. Just do what's easiest and best for your situation. Thanks for watching!
Mike Thompson thank-you so much Mike...but I'm also having trouble estimating the size, since four people need head space inside the dome, and the maximum length if strut i can use is 18 inches (it's a college project, and I'm an architecture student btw) so what frequency of dome would be most suitable?
Purva, let's discuss this over e-mail to minimize space on here. Mike@mikesinventions.com
Making this at explorers helpful vid ;)
You're Welcome Murray! Glad it helped.
if my A is 30cm my B is going to be 25cm???
Your B is going to be 26.53. Here's the reverse strut calculator link: www.desertdomes.com/rev2calc.html
if my A is 32cm my B is going to be....??????
thank you! :)
Couldn't this be used as a frame for a small personal "Planetarium Video Screen" or any Fisheye video screen?
Yeah I suppose it could.
how much small and large tubes are required
Hi! This dome requires 35 long ones and 30 short ones. Check out 1:16 for the length calculation as well. Good luck! It's a bit tedious at first, but it's totally worth it.
I'm very late to the party, but after inverting that pentagon in the dome and turning it upside down, you could now use it as the base for another dome to gain more interior volume/a higher roof while the radius remains the same.
I learned a lesson.
Yay!
great!
Thanks Junior!
@@MikesInventions if I may, in this vídeo you gave a Ratio for the length.. .883... is there a ratio for the 3v dome paper (next vídeo)... Like A, B and C? Thanks again and congrats for making it very comprehensive!!
@@juniorpaz9943 If Dome Radius = Strut Length x Strut Factor, then factors for a 3v A: 0.349 B: 0.404 C: 0.412
@@MikesInventions Nice! I’m about to set up the 2v ... Then I’ll try 3V ... Thanks again!
If the A struts measure 30cm, how long should the B struts measure?
Hey Diane! The B Struts in that case are 26.53. It'll give you a radius of 48.5. Thanks for watching. Check out that link to desertdomes.com if you want to experiment with strut sizes and dome sizes.
Mikes Inventions mi
I didn't get the length of As and Bs, Basically any length I want for As and 88.3% for Bs?
Correct. It's only the ratio that matters.
doing this for dt
what is the diameter dimention of the paper strut ??
Hey Visal! It's about 3/8"
This guy reminds me of Jamie from Euro trip lol
If i would puild it from pvc could i do it all with only 1m long pvc pipes
The 1m long pieces would be your long strut (A), you'd then need to cut it a bit to get your (B) struts. You'd also need to come up with a way to connect them since you can't smash PVC and punch a hole through it like you can with paper or steel conduit. I would recommend cutting thin strips of flat steel bar that just fit inside the diameter of the tube. Then you can drill through the pipe and this bar and insert a bolt. With a portion of the bar sticking out of the end, you can then drill another hole on that end and bolt them together to form the star joints. The flat steel bar would allow you to bend it between the bolted star joint and the pipe bolt to give you the proper angle. The strut length you measure would then run from joint hole to joint hole, so your longest A strut would be slightly longer than 1m to account for these metal bars on the end. This means you get a bigger dome! It would be a lot of work, but that's about the only way to do it with pvc. Although, PVC can be bent if heated with a heat gun, but it's a pain. And you still need some way to connect them. I did find a company online once that sold PVC joints for geodesics, but the fittings were very expensive.
@@MikesInventions you can heat pvc ends and flatten them then drill. PVC works well when heated
Can this design be used to build a aviory?
I suppose so, with protection against the birds chewing through the paper. Wrapped in tape perhaps, or coated in something like flex seal maybe. Interesting application.
Mike's response was great... I am thinking about building a big version of this for an aviary, cheep plastic in the winter and finch netting always.
Did you build one?
Did you use A4 or A3 sized paper?
A4 is the closest size to what I used here. I used US letter size actually, but I would have liked to use something larger, like 11x17 or A3 if I had it. Thanks for watching!
Well.. that is big :) Great for my homework but maybe too big :/
cool
Thanks! Hope its helpful.
I noticed that that Dome radius is the golden ratio
At what length should I poke the holes?
Hi there! You'd poke them at a length according to that formula at the beginning of the video. It's all dependent on your strut length. Just leave enough at the ends so the holes don't tear out.
Mikes Inventions Thanks 🙏
Mikes Inventions keep up the good work
where is down part ,....,..........
love it will surely make this

How much load this can bear?
Hey Isuri! I'm not sure how much it can bear. I've only tested it with 3 small bears. ;-)
😜😜 we have an assignment to make a dome using paper and cellotape only which can bear 500g or more. 😄😄
With thick enough tubes and enough tape, it'll easily support whatever you want. You shouldn't have any trouble at all. Good luck!
What’s the dimensions of A and B?
Hey there! I don’t remember what the dimensions were. Only the ratio between the strut sizes matter
@@MikesInventions thanks
You can see the original dome and equipment on my channel, friends.
Hi
He sounds like Linus
can always use glue instead of tape
good idea
HOMELESS!!!..... thank you! thank you! thank you!..... i could fill in with cardboard or 'railroad board'to make a SMALL SLEEPING SHELTER! maybe, glue layers of newspaper over that, as in papermache! then, paint, several times. or varathane!..... KEEP THE DOWEL(S) and use the rolled-up paper on each end/(dowels) for the joints!..... when HOME is up, THICKLY papermache the paper joints?..... foam-board the entire outside of dome and papermache again!.....
YOu could also get a job and work and earn enough money to rent a place... just saying.

2:13 ! If you ever drop a blade, you NEVER EVER do what he did there! Replacing a dinged blade is cheaper than replacing your finger. Just let it drop, kids.
Not clear...how did u do third row??? A or b....most unclear demo
I"m confused @6:30, he says he used long for first ring B's on the other parts of structures., did u figure it out?
Straws
Straws and string make pretty strong triangles. Hot glue the vertices after assembly. Building a model is useful for figuring out the best way to assemble the full size structure.
Hey, have you ever heard of this thing they use to punch holes in paper called a "hole punch?" There's a place called a "stationary store" or "office supply store" which sells them.
But a bag of paper straws
use newspaper...
Just get straws from McDonald's
