Experimental Raspberry Camera

The is a case of the raspberry camera to experimant with different lenses or filter glassed.
In my example I tested an UV band gap filter (ZWB2) from china and a glass lense of 35mm focal length. The focus, or the position of the camera slider, can be shifted by turning a long M4 screw from outside the box. The slider holds a fixed M4 nut and the screw is hold by 2 counter-mounted nuts on the boxs wall.
