The bells .. the bells

Soooo Bells have been cast for thousands of years ,obviously when used,, as they very often are, in sets the tones must match, therefore there is obviously a fundamental formula for casting and the all important proportions https://www.msu.edu/~carillon./batmbook/chapter5.htm

Yeah Peter Davey actually says "sonic" and I don't doubt, I wasn't meaning to indicate either/ or but rather "and & also" sonic yes but reactive up through "sympathetic frequencies" and so "electric" also as part of the spectrum ..still as I say just thoughts on this old project and wondering about a better way to tune , I too have done that angle grinder and file business .. very hit and miss

[wrtner]

If you are worried about the voltage, you can always use a variac. Also, so long as the bells are tuned to each other, you can supply any AC voltage at that particular frequency.

I think water hammer and some of John Worrell Keely's ideas are involved.

So I posted on this lethal contraption long ago, I also did a short suicidal video, since then I have had a nagging doubt , something missed .. here it is , first this video.. let me explain is simply of two stainless steel spoons separated by lighting flex and then dropped in a jam jar of tap water.
The whole being plugged into a 240v mains supply. The meter connected is on a 10A FSD scale.
I'm afraid the meter needle is quite difficult to see, however you'll see it in the mirror if you watch carefully.
Its inconceivable the grid voltage would alter, therefore the current is directly proportional to power
being used. I would have assumed this current to be pretty much linear however it is anything but that, notice at the start there is very little current draw in fact the needle only just makes it off the stop slowly rising until the water is first boiling and then boiling furiously at which point the current draw drops away quickly again to pretty negligible.

good ideas Duncan, however I still state it is due to sonic vibration changing the intermolecular bondings. I can feel exactly that weird action on my hand after a long usage of oscillating hand grinder. The area between electrodes become full of steam and magneto or electrostriction effect cause water vibration and faster heat up.

a nagging doubt from my back pages!

The woks could be tuned to exactly the same note REGARDLESS of
local AC frequency. A micrphone in the water will pick up the sound
that they ring at. This is fed to an amplifier and the output of that
amplifier goes to the woks.

...remembering, as you will, that Hi Fi amplifiers expect a certain
impedance at the output or you may find their output transistors
blow. An impedance matching transformer may be needed.

*** An interesting opportunity ***

In the UK, the store Robert Dyas are selling a two wok set at
considerably reduced price.

One is 25cm rim diameter and the other 30cm

These might well fit very well together in a Peter Daysh Davey
set-up, and it may be possible to tune to the fundamental mains
AC frequency, 50hz or 60 hz.

But there is another possibility mentioned by me at Patrick's 2008 UK Free
Energy Conference, namely this:

The woks could be tuned to exactly the same note REGARDLESS of
local AC frequency. A micrphone in the water will pick up the sound
that they ring at. This is fed to an amplifier and the output of that
amplifier goes to the woks.

This has the benefit that it can easily run off batteries and the
amp, which needs to be mono only, could be built ultimately out
of components (instead of using a Hi-Fi amp).

The other huge advantage is that if one fails to get the woks tuned
to the first attempted frequency, one can grind more and go for the
next one. (You can't do this when going for 50hz. If you miss that,
you have to go for the next octave, 100hz, which will mean cutting
a huge amount of wok away).

Thanks.
What I ask and what answer you !

You have to remember that this is about ringing and resonance.
Accuracy of the tuning is what gets the performance.
You need decent bowls, not beer cans.
Remember to tune to an octave of YOUR mains frequency.
Best of all, put a cheap speaker across your mains with a fat resistor.

Yes. Try it and see.

Hello to all.
I read with interest everything on this thread.
Does anyone here managed to make at least 1 ml of warm water with this sonic device?

.
Yes. Try it and see.

Sonic device that really works?

If you have an android phone there's a free application that you can download. It's a music tuner. This is good to tune exactly to the preferred frequency.

But the preferred frequency is that of your local mains electricity,
either 50hz or an octave (100hz, 200, or 400 hz) or in the USA
and other places, 60hz or an octave (i.e. 120hz, 240, 480).

The best solution is to tune directly off the mains, by putting
a small loudspeaker in series with a fat resistor across the mains.
(Get your sums right or you will blow the speaker). You could
listen out for mains hum coming off a transformer.

Tuning can be done by cutting a groove in the hemispherical
bowl (as church organ pipes are tuned) or by grinding down
the rim until the note is right.

Yup you are right, The bells with hemisphere shape are already tune to certain frequency already. The problem is that those kind of shape will be pretty hard to find nowadays. I will try to find a pair. But I really want to look into how to tune to certain frequency accurately, this will solve the problem.

You would be better off reverting to the bells (or bowls) used by
Davey which are made out of substantial material:

I bought three different beer cans

I hope the beer was good because I have little confidence that
the build quality of the can will give any dependable results.
