The servo is hooked up to the Arduino via pin 9. I've uploaded one of the example sketches you get with Arduino ISP called 'Servo Sweep'. The servo is powered by a 24 volt rough DC supply as you can see in the video. The 20mm steel boss was machined and bored out concentrically to 8.0 mm. A 5.0 mm hole was drilled in the side of the boss and tapped to take an M6 grub screw. The boss was welded into a piece of 1/8 inch steel plate to make the servo arm.

Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!
