Hi again folks.
I am a bit of a photography person and was seeing some "tricks" with sound and water at a site.
A small flow of water was falling in front of a speaker and it was oscillating at about 34 Hz.
This made the water do some weird things.
If the frequency was adjusted a small amount it looked like the water was falling up - rather than down.
Yes, this was a video, but the shapes the water was made into was quite nice.
So I was thinking: Can I make a circuit to oscillate from ...... 5 to about 100 Hz?
I understand I will probably need an AMP as well. Dunno if the normal off the shelf music one would cut the mustard, but that's something else.
