That's it. If it was any deeper, there's no way I would have got there. :)

Dave,
You got pictures/video of yours?

That`s a bit clever innit! :clap:
I used to stand mesmerised at the pretty vibration patterns in the coolant puddle, at the end of milling m/c table.
(It still doesn`t take much to amuse me). ::)

Eric,
Didn't take any pics. of mine. Just a rather corroded brass plate. I doubt if the salt pattern would show up very well. That, and my less than competent antics with the camera. Apparently it will take short video, but I've never tried it. Despite a lifetime in Digital Electronics, to my shame, I don't get on with the wretched thing. I used to do 35mm stuff quite a lot. Even did my own prints and enlarging, but this thing is a mystery to me. I just about take some reasonable stills, but that's my lot. So, in case anyone was interested, I grabbed a Youtube example.
Far better than anything I could have done.
I didn't set out to make a Chladni plate, a friend wanted a brass disc 6 1/2" OD with a 5" hole, it just struck me, being a hard plate it may well work. My mind wanders a bit. Nothing more pressing to do, so I got the old speaker, a 15W audio amp. and my Signal Generator, and played about a bit.
Speaker has now had it's magnet salvaged, the rest dumped, and the brass plate has been trepanned and collected. Pretty much it. I live a frantic life don't I?
Dave,
Why not watch vibration patterns? ... I like 'em. They're free, and rather more interesting and animated than eleven solid hours of golf on BBC2. ::)

Interesting. Would the shape of the plate influence the patterns (at the same frequencies)? Or for that matter would changes in size (thickness, linear dimensions (square, rectangle, circle), type of plate (steel, wood, plastic, copper, etc) change the pattern perhaps because of resonance?
[Looking around shop to see what I have to try it]
