Building a Cardboard Planetarium 

Thank you!

Ha! When I saw your channel I wondered why you didn’t have a million subscribers then I realised that maybe not everyone is obsessed as me! I found you on Reddit, then your YT and Etsy followed. I’ll be giving you rotegrity ball a go as soon as time allows! Look forward to seeing your channel grow, and I’ll certainly be watching with interest if you do any explainer videos. On the off chance others are curious, check out their shop here: www.etsy.com/uk/shop/OrigamiMarieArt

Thank you! I didn’t except the dome to last too long but was quite surprised by how quickly it took on moisture and collapsed - we maybe had 3 or 4 days out of it. It was the morning dew that ended it despite it being warm otherwise. Good luck with your version- it sounds intriguing!

Yes I imagine a decent projector would increase the magic! Good luck!

@@RussellEveleigh this awesome!!! I’m looking forward to making one but I have limited space. How big was the dome after fully assembled

Good luck Adriana! It was just about 3m across when finished. And about 2m tall. Have a look at the article I posted in the description for further details. You could use the tools there to easily scale down the size if needed. Thanks for watching and for your comment!

Good luck!

Have just Googled Snapology and it looks super fun. I'm going to give it a go. Thank you.

@@RussellEveleigh Takes time, but wow, the results are pretty remarkable. I recommend the Fiskars SureCut 154450-1009 for quicker cutting of consistent width strips. If you find a better approach or tool, I'd gladly take your feedback. I'm currently working on a 6-frequency dome to encapsulate an Ikea FADO lamp for a friend's kiddo.

Gracias

No, predictably the whole thing only lasted a few days. A straight projection worked the best. I don’t think you could get the full curved effect on a budget. I keep thinking about it though.

Thanks for your nice comment! I wrote up the project with more info - link in the description - but if it is just calculators you're after checkout this site: geo-dome.co.uk/article.asp?uname=calculation

A good idea! I'd love to make another one - just need to think about waterproofing and making quick to release connections.

Rain is a definite problem!

First of All: very Nice Project ! About this water problem: Applying Ship (Yacht) Varnish on the cardboard before assembly… also putting the bolts on the inside would turn the outside into a more smooth plane because now you have those upstanding sides creating a collection effect for water. Application of silicone in between the triangles, already mentioned by Tony Hardy, would seal the whole from further water penetration. Ofcourse you would have to apply an extra projection layer on the inside but I think it can be done. I also think if a person wants to create a larger structure with this cardboard material it will be more easy and safer to secure the bolts on the inside since you cannot climb on the outside or reach too high… anyway, I think it’s a very nice approach of a practical geodesic dome creation. Well done.
