Geodesic Dome for Idiopolis

Dome Construction 9.jpg {{#if:No | [[Tool Owner::{{{ProjectParticipants}}} | }} {{#if:No | [[Tool Cost:: | }}


Introduction

As Idiopolis, we have this super cool army tent at our disposal, but it's getting a bit flimsy, and it is not entirely sure how long it will survive. On top of that, all our party tent have been frankensteined into a mother of all partytents at haxogreen, but unfortunatly it has met its demise at the hand of the weather gods. I believe this provides us with ample arguments to consider a new construction for idiopolis, after all, CCC camp is just around the corner.

Proposition

I propose to build a geodesic dome to house our chaotic village in.

<insert cool geodesic dome pics here>

Pros:

  • Strong construction due to its nature
  • Durable
  • Broken parts are easily replaced
  • Spacious
  • Could be used as place for giving lectures/talks/open discussions
  • And kinda cool
  • Few different kind of parts

Cons:

  • Lot of parts
  • Possibly heavy
  • Possibly bulky
  • Lengthy construction time

Construction of full scale ziptie hub prototype


Minidome strut construction

Cut:

  • 50x 15.5cm tubes (L, purple in construction diagrams)
  • 40x 15cm tubes (M, red)
  • 30x 13cm tubes (S, blue)

Dome construction

-Things to remember:-

  • The dome only consists of two types of triangle - LLM and MSS. If you ever construct any that don't match these, something has gone wrong.
  • All six 5-way hubs can be populated with M pipes before further assembly
  • Similarly, 5 6-way hubs can be populated with only L pipes.
  • M struts never occur next to each other on any single hub.

Construction of 4m prototype

Required materials:

  • 30 x 'S' : 0.70m x 16mm PVC
  • 40 x 'M' : 0.80m x 16mm PVC
  • 50 x 'L' : 0.82m x 16mm PVC

We will need 24 4m x 16mm PVC pipes + 1 extra = 25 pipes. Cut them as follows:

  • 13 x SMLLL
  • 9 x SMMML
  • 1 x SSSLL
  • 1 x SSSSS


  • 25 x 6-way connectors
  • 6 x 5-way connectors
  • 15 x 4-way connectors

Total = 46 connectors. A connector consists of an inner ring and an outer ring. The inner ring is a 40x20mm PVC ring. The outer ring is a 75x35mm PVC ring.


  • 46 * 20 = 0.8m tube to make the inner rings
  • 46 * 35 = 1.61m tube to make the outer rings.
