What?

A geodesic dome (V4 design) built from slatted frames (Lattenrostbretteln)

It was built during Stadtflucht 8 in the Summer of 2015 right before the CCCamp.

The total cost was below 200,- because only recycled slatted frames were used.

Construction took about 10 hours with estimated 10 people involved.


Preparation

Want to build your own? You need:

  • 250 bars (get 270+ to have some spareparts) the inner parts of slatted frames for beds work great
  • 91 M6 screws (length: 80 mm)
  • 91 Wing nuts
  • 182 Washers (the bigger the better)
  • Spray paint (RED,GREEN,BLUE,ORANGE)


Cut them in 5 different lengths.

Type Color Pcs. Length
A ORANGE 30 60cm
B RAINBOW 90 70cm
D GREEN 70 74.2cm
E BLUE 30 77cm
F RED 30 70.8cm

Drill a hole 2cm from the border in the middle of the struts ends.



Assembly


Start with 5 pcs type A struts (orange) Connect them like this: WASHER, SCREW, 5 BARS (A),WASHER,WING NUT, dont over tighten yet

You successfully put together the middle structure that will be on the center top of the dome.

Now from the end of these connect 5 type B struts. The magic formular is:


MIDDLE - LEFT - RIGHT


  • MIDDLE (A) outermost layer
  • LEFT (B) middle layer
  • RIGHT(B) innermost layer

and thats how you go on according to the diagram above.


This is true for the whole assembly.

Take a corner of a triangle, consider that "middle" and connect first left and then right to it.
