It would look really neat to combine this with Lord Kelvin's electrostatic spark generator, which also uses a falling stream of water. Two streams actually.
The frequency is the same as the camera - 30fps/30 Hertz. I only changed a little sometimes up and down (0.5-1Hz) to direct the jet in the right direction. For this kind of shooting, you need a lot of light to shoot at a short shutter speed, in my case it is 1/3000 of a second. I illuminated with twenty 3-watt LEDs from a distance of 20-30 cm and this was not enough, I had to set the sensitivity to 800 ISO and the aperture 6-7. Of course, the camera must have a manual mode. I did not understand the question about the headphones. The tube is glued with a small stick to the speaker of the sound column (on double-sided adhesive tape). There is a pot of water on top of the column, the other end of the tube is lowered into it. And I also added two pieces of gauze to the upper end of the tube to make the stream smoother. In a serious way, you need to make a laminar flow device, but the topic is already old, the video will not give many views, so I did not bother with it.
@@grain-diose I know that the video is not new, but your skill in directing makes it very wonderful You are an inspiring person in determination, challenge and success. Greetings to you
Основная также как и частота камеры - 30 Гц и плюс/минут десятые доли или 1-2 гц для движения вверх/вниз. Если ваша камера 25 FPS, то соответственно нужно 25 Гц, если 50FPS, то 50 Гц.
