Build a homemade geodesic dome
A Geodesic Dome Some years ago I built a geodesic dome out of ½ inch galvanized steel electrical conduit, to serve as an aviary for chickens and small parrots. I wrote a computer program to calculate the proper lengths of steel tubing, and draw the diagram shown below: The dome is made from three different lengths of tubing. I used colored stickers on the tubes to mark the different lengths -- red for the long ones, violet for the medium lengths, and green for the short ones. You can see those colors in the drawing. The ends of the tubes are smashed flat with a hammer, and then holes are drilled in the flat ends for a bolt to go through to connect up to six of the tubes together. For this project, something a little more modest in size is required. For the first attempt at a smaller dome, I used bamboo kebab skewers and gumdrops. You will need these materials for the gumdrop dome: Click on photo for a larger picture The dome is made of pentagons and hexagons. We end up with a nice dome.
