This is a Dance Dance Revolution machine (a popular arcade game), one of my more in-depth projects. Making the CAD models with this project was only the first step; I am also constructing a working real life model based solely on my CAD designs. The inner workings of the machine (wiring computers etc.) are all included. You just can't see them. I had no idea how the arcade machines mechanics or electronics functioned so I had to design them myself.
