I know this is not a electronic or circuits question, but i imagine some of you have built a robot or something that requires not only the electronics but also some kind of physical part (what the old RugWarrior called "the brawn") I am talking about the place where you put your motors or something like that So if any of you has done that, how did you do that? what did you use? Acrylic? plastic? how do you cut those btw? I come from the programming world, my experience with electronics is limited but my experience with building something of scratch is nil! any help, comment, anecdote or suggestion?
