Geodesic Dome Materials

My friends and I plan on building a geodesic dome at a small park, but we're not sure what materials to use. Our criteria are:it needs to go up fastit would be nice if it was semi-portableit needs to be cheapit needs to be secure enough that it can't be vandalized/removedSuggestions, please? Thank you!

Raising a geodesic dome

Just thought I'd share a time lapse video I made last year (but just got around to putting it online) Two of my kids are involved with a local circus and last year, said circus bought a geodesic dome to use as a venue for shows. There was great excitement when it was delivered and put together for the first time. It seemed appropriate to record the momentous occasion, but knowing how long it was going to take, a normal video was out of the question. So I set up the tripod and camera and took photos roughly every five minutes. The first photo was taken just after 9am and the last one was taken just after 5pm. It's quite an interesting structure and so strong, they can rig the aerial apparatus from just about any point!

geodesic dome hubs

Hi everyone i have been wanting to make a geodesic dome for a while now and i dont want to spend money ond conduiting which looks easy to do and all the angles associated with timber domes seem over complicated so i thought that pvc/ plastic pipe might be cheap enough though i find the hubs extremly expensive so i thought up a design that is in between almost all homemade hubs. the center of the hub is circulat like the pic and the bolts potrude at all apropriate angles then on the bolts is a rubber sleeve that snuggly fits into the inside diameter of the tube you are using then when you tighten the bolt the rubber is squished and pushes outwared on the tube so the hub stays on the tube just thinking that someone here might be able to improve the desighn and or make it. thanks for your ideas.

Fabricating a 1"-2" transparent dome?

I need to create a small, transparent dome (out of some sort of plastic or resin) that will be able to be glued to a flat surface. What materials are out there to make something like this (that I will be able to do as smoothly and evenly as possible)? It will need to be able to magnify an image underneath it. Sorry if I don't have enough details on what I am trying to do, I have never made something like this before so any help will be very much appreciated. Thank you for your time.

Glass dome / cloche Display

 I am in works of putting together a glass dome with a wood base and a model inside. I am looking for ideas of ways to have the glass dome lock itself onto the base and having the option to unlock.  So I do not want to permanently bond it I'm trying to think of some clever way of being able to have it lock whether you twist or some other way but I'm stuck .  The photo below is similar to the shape of the dome I have acquired as far as shape I will just be using a knob instead of a rope on top and then below that is the bottom base I have which is more like a plate  and not as deep as that first image

Automate Astronomy Dome - Help

I am interested in building an electronic system to control the orientation of an astronomy dome based on the orientation of the telescope. I need suggestions on the various components I might use. Motivation: This is a Meade 16" LX200 telescope in an Ash Dome. Owned by a friend who doesn't use it much. I get to use it, maintain it, enhance it for about 1 week a year. I can control the scope with my laptop using a program like "The Sky". However, after the telescope is pointed, I have to manually manage the dome and rotate it with a bi-directional switch. Very tedious. The motor is 1/4 HP, 1725RPM, drawing 5.6 Amps at 120VAC. There are programs that can be used with the telescope control to manage the rotation of the dome, but I am thinking of a lower-tech solution. I would like to put some reflecting tape (perhaps mirrors) on the sides of the dome slot and point some lights (perhaps LED lasers) with a pickup device (hence the idea of the garage door styled "electronic eye"). The general idea would be to set up some simple device that would detect the change in location of the direction that the telescope is pointing, and activate the dome to track with the telescope. If the telescope turns, the light would no longer be reflected and the dome would try to "find" itself or re-orient to a point where the light is once again detected by the reflection from the mirrors on the dome. I was thinking about: Garage door electronic eye activators 120V 6A relay switches 2 enhancements: detect direction of the telescope; bar codes in the reflective tape wireless signals to send activation to relay switches (telescopes go in circles and eliminating wires is always good.) Anyone have any ideas about pre-built components, sources of good relays, electronic eyes, etc? TIA, Chris.

ONE of my new projects requires a DOME: I need a simple way to make one. Any Help?

I need a dome, and it need not be really big.  It DOES need to be made of a thin enough material to have multiple hole poked or drilled into it (fairly SMALL holes actually).  I am at a loss as to what to use.  It needs to be opaque (even if the light beneath it is very bright).  I would like to create a kind of a planetarium in my room, but have it mobile so I can move it into another room if need be.

12-year-old wins design contest with plastic dome

Design competitions aren't just for adults, as 12-year-old Max Wallack has proved by winning $10,000 for his plastic dome for the homeless built with trash.Twelve-year-old Max Wallack of Natick spent a day last week being followed around by television cameras, hanging out with engineers and building a model of his latest invention: A shelter for the homeless made from plastic, wire and packing peanuts.The folks at the WGBH show "Design Squad" selected Wallack's idea from more than 1,000 entries for their Trash to Treasure contest. As the grand prize winner, he will receive $10,000 from the Intel Foundation and a laptop computer.While the action is noble, I have to wonder what homeless person would ever use this. Here in San Francisco we have our fair share of homeless folks on the street and the basic cheap camping tent seems to be the home of choice. It folds up and can be carried around in a shopping cart. Any time there is some encampment that is big enough, or around for long enough, it gets broken up by the police and everyone moves along, making this useless.Also curious is why the dome keeps getting called a yurt.
