Yo !

Here is my Schlieren photography setup :

The mirror is a 150 mm diameter, 1.5 m focal length, 80-50 surface quality spherical mirror bought on Edmund Optics' website (http://www.anchoroptics.com/) mounted on a home-made mirror mount with x-axis rotation controlled by a screw.
The camera is a Casio ex-zr1000 and the movie is recorded on auto-focus mode, auto-iso mode and zoomed in so that the mirror fills in the full view at 120fps - 640x480px, 240fps - 512x384, 480fps - 224x160 and 30fps - 1920x1080.
The filter is a sharp razor blade.
The point light source is a 14000 mcd - 15° - 3.2 V - 20 mA LED controlled by a potentiometer, a switch and a 160 ohm protection resistor.
All the mounts are made out of 15 mm MDF, 5 mm plywood, and aluminium rail.
