My name is Jacob Siler, and I'm currently co-founding a game development company through crowd funding. We're working on our first game, named Sky Bridge! It will be a massive online Steampunk universe -- quite unlike any game currently on the market. For more on the company (and the game) please stop by our facebook page at facebook.com/skybridgemmo and help out on our funding campaign if you choose. Now to show you one of the Steampunk items I've built with my hands.

Around mid-October I got news of a steampunk/Shakespeare-themed Halloween party being planned at the local University. It was put on by a student organization, and they needed decorations for the celebration. I decided to pitch in something that I would enjoy planning and building -- the hope was that it would add the ambiance of some mad-scientist steampunkery to the room.

The general idea was to design something that Shakespeare would have in his office were he a steampunk mad-scientist.
I have a thing for geodesic shapes so the idea came to make a geodesic terrarium to go in the room. It was to be a dome originally.
I wanted to add fairies to the terrarium alongside the mystical vegetation.
Then some costumes my sister and friend were looking into inspired me to make the fairies from A Midsummer Night's Dream as a central theme of the terrarium.

Eventually I couldn't help myself and I chose to make it a complete geodesic sphere, whith sculpted clay fairies and light effects all over the inside landscape.

I am sure that the Bard would be proud to have the fairy cast of A Midsummer Night's Dream  in his laboratory terrarium -- assuming, of course, that he were mad, a scientist, steampunk, and also pleased himself by keeping fairies stuck in a sweet geodesic display.
I can see it being a subject for an intirely different play.

In any case I hope you enjoy the instructable, and can take something useful from it for your builds.


Step 1: Building a Geodesic Sphere

This part was tricky at first. I did a lot of thinking about this step and finally had to fall back on information from the internet (Don't judge.)
Regardless of how I came to know about any of this I learned a few things about Geodesic domes and spheres and how they are put together. I didn't learn a whole lot and there are large volumes on the subject if you are more interested in that aspect of the instructable.

All of the necessary findings I used can be summed up in this link.


I was not very practical at first in trying to tackle the idea, but this website saved my life and I give full credit to those who made the site. Let me be clear that none of that is my material. I relied on the site to help me figure out the lengths for the struts I eventually used.

Let me break down the simple jargon you may need to work on a dome, or sphere of your own (this is almost indispensable if you have a team working and don't want to make up all of the verbiage used.)

These are the intersecting points between each group of triangles that make up the shape: essentially, the vertices.

These are the lines that connect the hubs to other hubs.

Clicking on the above linked site will make what I just said very evident.

There are different levels of detail in a Geodesic sphere, and the math can get a bit complicated if you're like me.
To break it down to a simple level was my first priority, so for my sphere I decided to make a 2V shape because 1) it was simpler, and 2) it was cheaper. Since this was my first geodesic build (except for a straw/pipe-cleaner structure) I wanted to use my material effectively and make something that also looked nice.

There are a few things that are good to know when building a 2V geodesic dome or sphere:

1. There are six pentagons in a Geodesic dome, in a sphere there are, naturally, twice that many -- two domes connected make a sphere in this case.

2. There are ten struts across the bottom of a dome, on a sphere half of those struts are unneeded on both domes because the pentagons' bottom edges interlock, making the full circle complete (This will explain my use of less material later on down the page.)
Hence for a dome you do not need to make a bottom edge at all, only focus on making the six pentagons.

3. Finally the letter V in 2V, 3V, 4V and nthV domes and spheres is actually the letter Nu. Though I was originally trying to use Pi to figure out my sphere, with the calculator you can get away with Nu, or less (don't worry - I could even do this; no math skill required.)
<p>Well I cant place the link. Just visit waybackmachine site and you can find the byexample site mentioned in the article.</p>

Interesting, but link doesn't seen to be working.
This looks like it http://www.byexample.net/articles/topics/geodesic_domes.html
