== 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:
You need:


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

Start with 5 pcs type A struts (orange)
Connect them like this:
Connect them like this:
WASHER, SCREW, 5 BARS (A),WASHER,WING NUT, dont over tighten yet
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.
Now from the end of these connect  5 type B struts.
The magic formular is:
The magic formular is:


MIDDLE - LEFT - RIGHT


MIDDLE (A)
'''MIDDLE - LEFT - RIGHT'''
LEFT (B)
 
RIGHT(B)
 
* MIDDLE (A) outermost layer
* LEFT (B)     middle layer
* RIGHT(B)     innermost layer
and thats how you go on according to the diagram above.
and thats how you go on according to the diagram above.




this is true for the whole assembly.
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.
