I’ve been planning to build a tensegrity icosahedron all summer. I’ve got all of the parts prepared and started putting it together today. Here are a couple of work-in-progress photos.
I build one small one several years ago out of thin wire and wooden sticks. This time I’m making something more permanent and bigger with steel pipes and wire ropes.
The third image is after I discovered that I have the cables tangled up. I’m having to disconnect them three at a time and then make each triangle not cross each other. This last one has 2 of 8 triangles corrected. I’ll make more progress tomorrow.
