Whats that inside the cup??
Braided wire to nut to?

Thanks
Chet

That little area i busted my but for sometime. It starts with a lamp nipple, then I have a crimp 'plug-in' connector that is sitting in pneumatic tubing. The tubing and connector are then rubber sealed after the wire is crimped to the connector to prevent any water from traveling up into the nipple. The rubber sealed plug-in connector is then glued into the lamp nipple. The hole thing is a pretty tight fit.

There are two thumb nuts that allow the tuning bowl to ride up and down as needed for adjusting. The copper wire is flexible and is pop riveted in. The black ring you see is a rubber grommet that isolated the can from the nipple, and allows it to swivel as in the patent.

I think I see

So in the pic the Plug in connecter isn't plugged in?
It goes to the Middle Lamp nipple?
Do I have that right??

Edit
Yes I see Now ...{the shadow}
It looked funny at first. Now I understand,That must have been a real Pain in the pants to get water tight!
Your going to have some fun Too..................

Thats correct, the plug is not plugged in. I plan on making a complete drawing with all the details of how the cups are installed. The threaded lamp nipple makes vertical adjustments a snap.

This looks good, Core, but rather complicated.

It is as well to be reminded of Patrick's drawing on page 12:

Nice link!!
I like the Merlib link too [in Kelly's link]

I wonder, Core, if you have a variac.

When the build is finished and is submerged in water,
it is going to take a certain amount of courage to plug
it into the mains and then stand back and switch on.

It would be better practice to use a variable transformer
and bring the voltage up from zero.

For those not up to speed on these, they all have a current
limit and are made by Variac and Staco. (There is a solid state
version which is pulse width modulated, and is questionable).

Ebay sells them quite often cheaply except that they are heavy
and postage costs can be high.

Haven't gotten around to testing yet but this weekend is looking pretty good. I have been able to figure out the frequency that my tuning cup rings at and it is exactly 400hz. I did this by playing a tone via a software generator on my computer. I have the bell hanging pretty close to the speaker. From here, when I ring the bell with a small metal rod, I can distinguish both vibrations (like tuning a guitar).

At 410 hz I can hear both wave lengths out of tune. I slowly drop the frequency generator until I hear the wavelengths match. At this point also the volume of that wavelength increases. To double check it I lower the frequency generator until I hear the two separate wavelengths again. In my case I can hear that 397hz is a little off. 400hz appears to be what this cup rings at.

Interesting note (no pun intended) I had cut the rolled lip off the cup as WeThePeopleUSA had suggested. This changes the tone of the cup dramatically, borderline cow bell sound but slightly cleaner. The cups with the lip on them ring with a much louder tone and can sustain the note much longer. Thankfully the rig is set up so that changing cup is a matter of seconds and not hours.

So 400hz is were I am at with the cup 'as-is'. As far as a variac, I have a small one, maximum current is 2.5 amps. What I will do is place a fuse inline to prevent constant tripping of my 15 amp breaker. I do have a 12v/120/ 300 watt inverter but this may be too small with a un-tuned rig.

So this weekend, if all goes as planned, I will have pic and maybe a preliminary video also. If its a total bust, meaning it just blows fuses, I will let you all know.

As it stands, to build the rig from start to finish takes about 1 hour or so. This is because I figured out all those pesky design details. The total cost, assuming you already have 3/8" soft copper, is less then $10.00. If you have to buy a roll of copper it will set you back $40.

Tonight I will make an attempt to figure out the length of a standing wave of 400hz. This dimension will then be used to space the cups.

Tesla Technology?

BTW - I have yet to hear back from the New Zealand gentleman who clam's on YouTube that this device is associated with Tesla. He also claimed the Davey was a friend of Tesla. If anyone can qualify these these statements that would be awesome. I do not have any info on Tesla using sound waves, or any patents associated with sound waves.

This would go a long way in building a rock solid theory. After we have a sound theory, verified experimentally, then there is no limit to what we can design with it.

Nikola Tesla (1856 - 1943) - Master of Resonance

It was an innocent experiment. Tesla had attached a small vibrator to an iron column in his New York City laboratory and started it vibrating. At certain frequencies specific pieces of equipment in the room would jiggle. Change the frequency and the jiggle would move to another part of the room. Unfortunately, he hadn't accounted for the fact that the column ran downward into the foundation beneath the building. His vibrations were being transmitted all over Manhattan.

A real Thriller!!

Core
This is exciting stuff!!
When did you start writing Thrillers?? I'm on the edge of my seat!!
Mystery... Danger... all you need now is a liittle
OverNudity!!!!!!!![Mr.T {Thane] word]
And you'll have a best seller!!

I recieved an E mail that said The beer can device was really the work of Tesla .
Validation of this has yet to be recieved ,it was claimed to be in some older libraries in Eastern Europe no longer in the US{removed]
Doen't matter to me
I don't believe for an instant That Davey was doing A party trick!!
Thanks for sharing!!

I think this is part of Tesla's earthquake machine or his device
to demolish a building by applying a signal which is the same
as the building's natural frequency of vibration, a technique
which can be applied to the planet.

Tonight I will make an attempt to figure out the length of a standing wave of 400hz.

A snag.

A standing wave should be achieved at half the wavelength:
Frequencies of Musical Notes
which amounts to roughly 43cm or 16 inches.

[RAMSET]

Wrtner I don't understand

Well actually I do understand the calculator ,I don't understand how your scale is so Small ?? [16 inches]

Please Look at this frequency wave lenght calculator
Just Punch in 60 Hertz or 400 Hertz

Frequency Wavelength Calculator

Thank you
Chet

[Core]

I'm getting different numbers then everyone else. For 400 Hz I'm getting a full wavelength of 12.17 Ft. Half Wave length of 6.088 Ft.

In my case I'm using this formula:

W_length = Speed / Freq.


W_length is length of wave in Feet
Speed is speed of sound in 70Deg. water (4871 F.P.S) Feet Per Second
Freq is frequency of wave

Is this correct? To find 1/2 wave divide by 2

Getting the math solid will be pretty important.

I'm being cautiously optimistic about the first test. The purpose will be to get some bench mark amp readings. After that I will move forward and tune the cup to the closest octave of 60 Hz. Then adjust the cup distance for best performance. Good or bad Saturday night I should have some basic data on performance. I am open to all suggestions so please fire away.

I've built also a 'safety whip', this is just a very short extension cord with a replaceable fuse....just in case.

I looked at the references listed above on the other replications. One of the things I noticed in Davey's YouTube video's is that the ball is 'moveable' meaning it has free movement. This is inline with his original patent and it appears the the other replications seem to have missed this detail. This is a detail I incorporated into my prototype for the tuned cup. I guess well see.

Here is a pic of the inside of the cup plugged in.



The final testing device. I added a sleeve on the flexible neck for safety.




This is a device I want to solve. I have been in the Heating and Air-conditioning field for 20 Years. Designing an efficient home heating system/Hot water system would be a snap for me after we figure out the important detail. I'm trying not to look too far ahead but cheap/affordable hot water would go along way in helping a lot of people.

See you Saturday night.

... is speed of sound in 70Deg. water (4871 F.P.S) Feet Per Second

Yes, you are quite right. My link was to a table of values in
air.

Either way, a standing wave is gong to be pretty impossible, as far
as I can see.

One way may be to have a slow flow of water over the device with
two thermocouples measuring the temperature of the water entering
and leaving.

This gives the energy entering the water.

Then have an ammeter in series with the power supply which will
give the energy being supplied.

This will give a COP fior the system.

Then take readings with the gap varying a millemeter per run and
see how the readings stack up.
