Well, I' m back with a project for a case made of MDF (Medium Density Fiber) wood compound. The idea was taken from high quality speakers. The material absorbes vibration and sound extremely well, so with my desire to create wind tunel, thus using many high rev fans, with minimal noise, makes this ideal! I have been working on this over the last 3 days, and it is a slow process... At the moment I am working on "one to one" scale model of the sides of the case, made out of paper.... I 'll be back later with some pics.... BTW, it is nice to be back!
