The amount of work involved, INSANE!!!
Now I am no true engineer, but I have some engineering courses, CAD work, and have messed around with a 3D printer before. So when I saw that Arthur Sacek created a 3D milling machine out of Lego Mindstorms, I was just floored with the amount of dedication that I knew he must have put into this device. Watching it work at first I was a little unconvinced but once he used that vacumn and it became clear, whoa! It was shocking to see how precise and acrticulate he had gotten it, using something that still comes across very childlike until it proves you wrong. Please watch and appreciate this man's passion. Give his website some love! Detz All Folks!!
