DISSOCIATING WATER, A KEELY Project

[hansvonlieven]

G'day Entropy and all,

Thanks for the information, now I have to find someone who can use this information to design a circuit for me :-)

The 40 Hz envelope does not worry me. 32 Hz is a 16 ft open organ pipe. I seriously doubt Keely was using acoustic resonators as big as this.

Yeah, I'm afraid I can't help you there -- I couldn't confidently design it without actually building it.  I could help you muddle through if you have a scope and a solderless breadboard, but since electronics isn't your thing, I'm guessing you don't.

Cheers,

Mr. Entropy

Here is available a simple square wave oscillator kit that will generated set frequencies at 50% duty cycle.

R1 and R2 can be swapped out with a pot to fine tune freq.

Cheap and it works, but I've yet to add the pots.

Hi KT

As I'm sure you are aware, that cct is effectively one half of Lawtons circuit, but as such, and with preset frequencies, not very versatile.

No offence intended, but I had to chuckle when I looked at Mr Entropy's post somewhere above. Hans had just stated that he was a little out of his depth with electronics and so, as if to rub it in, Mr Entrophy follows with a post containing quite detailed formulas and equations.  Why go for the less complicated, 'complex number arithmetic' when you can have 'trig identities', eh!  Perhaps it's just me, but I thought it was funny!

However, this is why having no technical or scientific background can make progress difficult, in that if you do stumble across something that works, you won't necessarily know why it works or how to explain it.

Excuse me if I butt in through a thread without understanding, but are you after 40Hz or 40Khz?

You may need 40 Hz for some other reason. If not, I think the wavelength (in water) of 42Khz is
around the 34mm mark.
