Description
I had a strand of 25 led's from adafruit laying around, and wanted to turn them into something cool, so why not a disco ball?
Each led got controlled RGB, and they are all controlled by only two wires.
Update 09-08-2012 #1
Added OpenSCAD files to adjust the hole in the stl file if tweaking is needed.

I had some problems getting the parts to align up perfectly and stay that way, so I made this "cornerHolder", you can put the ziptie through that when you assemble the cube, and they will then make the sides align as they should and stay secure like that! :)

Instructions
1. Order this adafruit.com/products/322
2. Manufacture 8 triangle, and 18 square parts.
3. Assemble the cube with zip-ties, but leave one panel so you can still get into the cube.
4. Put all the led's in the holes.
5. Fix wires so it can hang from the ceiling.
6. Put the final piece in the cube.
7. Make some awesome patterns in the sketch on the arduino controlling it.

Beautiful model and very neat idea to use cable ties.
Does it use 18 squares? I think the shape is a small rhombicuboctahedron ( http://mathworld.wolfram.com/S... )

Any reason this is printed rather than lasercut? Seems like its flat so that should work.

Can you post dxf files (from the 3d program) of the triangle and squares for us laser engravers to make and then assemble?? thx
