Sure, the next time I build one (or any other thing for that matter) I'll make sure to take a bunch of pics with explanations and post them here. But the box itself is super straight forward: four sheets of plywood, plus the top and the bottom. I used the very cheap type of *esquineros* (don't know in English, corner squares?), you can see in the bottom left pic, but any other way of keeping them together works. Originally I also lined the inside edges with recycled styrofoam, but there was no need for that. They got loose, so I took them out and it works beautifully without. What the photos don't show you is that between the front wall and the bottom there's just enough space for the solar panel to fit in. That white stripe you can see on the outside (upper right pic) is a metal cover, with some styrofoam jammed in underneath, to make sure the air flows from the panel into the box. Notice also the holes on the top of the door (upper left pic) where the hot air can finally leave, having passed through the box. They are covered with a wire mesh, just like the bottom side of the panel, to keep insects from getting in. The roof, as you can see, is *chafisimia*, so I won't even get into explaining it. The 2x4s on the sides are purely structural, to keep the whole thing in place, as I didn't want to drill holes into that wall on the roof, covered in waterproof paint.
