Reducing 110 Volt Mains Amperes to 15 Amperes?

What you supply area of the apartment, you calculate the width and thickness of the electrode, zero reba to resonate at 300 Hz. Fuse will die if you are using electricity for over 15 Amperes.


How do we control our amperes from our mains down to 15 amperes so we don't have problems?

But as soon as that tuning fork touches the water it stops vibrating the instant it hits the water.

Air is a fluid like water, and oil. Resistance of the air over the tuning fork will eventually cause the vibrations to stop assuming no additional power is added other then the initial hit.

In water, these vibrations will be dampened faster. However it will still vibrate underwater just not as long as air. Sound travels via longitudinal waves. A tuning fork creates longitudinal waves. To say that a tuning fork will not vibrate in water is to say that sound does not travel in water. If that's the case how does sonar work?

Nice!!

Core,

Very good recommendations and very sharp. Thanks!!

I have never seen that beer can.

Sanding a can is straight forward.

1. Cut can open and add painters tape to sharp edge to prevent yourself from getting cut.

2. Install a rod and nuts on other end. Maybe a #8 threaded rod will do.

3. Get a large rag/towel that when rolled up will fit inside the can.

4. Wet the rag real good this will remove more air from the can and strength.

5. Cut a piece of strong cardboard to match the opening of the can. Make it 1/16" smaller so it fits inside.

6. Tape cardboard to inside of can, this prevents rag from falling out.

7. Mount can on drill press, on low speed, and use plumbers sand cloth to thin metal. OR staple some sand cloth to some wood (2x4) and mount this in a vise. Mount the can on a cordless drill. Run the drill and slowly move it across the sand cloth in the vise.

Yes getting the can tuned will be a pain but important.

BTW - We can also build the European version. Simply get a 120v/220v step-up transformer.

The contact appears to warn us from simple plugging the unit into the wall outlet. I think anyone can see that if conditions are not perfect or if your water is very conductive we are creating a bad short. Distilled water would be good for experimenting.

For starters I recommend we use a 12volt to 110volt converter of say 150 watts. These inverters have overload protection.

I understand the concept, but I just don't see it working once in the water.

In one of the diagrams it shows a pos and neg. Well AC isn't DC. That pic implies a pulsed DC current from what I can tell.

Why not just find out whatever you put together resonates at, once you get resonance of your can setup then put it in the water and see what happens. Will it stop resonating? Will it heat the water at least a little bit? If so then I guess your on the right track. I just don't see it working once it's in the water.

[Core]

How do you plan on getting it to resonate once you dunk it into the water? Or is it a sealed resonant chamber that you put into the water???

The concept is that when an alternating signal is passed into the can, or any piece of metal, the can will vibrate at that frequency. What is important is that the can be tuned to the frequency of the line frequency used.

Think of it as two tuning forks tuned to middle C. If you strike one tuning fork and hold it a few inches away from the other fork it will cause it to vibrate.
Also if an alternating electrical signal of 278.4 Hz is passed to a middle C tuning fork the fork will vibrate and a sound will be heard. 278.4Hz is the frequency of middle C.

Tuning Beer Can

This tuning the beer can could be a real pain in the neck. My contact said to sand the can but never elaborated where as I recall. That thin aluminum is hard to sand on whether your sanding on the end or the sides.

.5 liter European Beer Can

Chet,

One of my European contacts said that the .5 liter beer can is a standardized European size and that you can find European beers in cans like that all over US without going with a particular brand of beer. I was asking the same question.

have you seen his brand Beer in the deli?
I won't be in NY till mid week !

Thanks
Chet

[Slovenia]

Thanks!!

Core,

You are absolutely correct. It would appear like you said that tuning the beer can is the most important first step. Thanks!!

Regards,
Slovenia

According to your contact a beer can is not the only thing you can use. One only requirement appears to be that the metal fundamental resonate frequency of 60Hz or 50Hz. To get this the cylinder has to be honed/sanded until it rings.
This can be checked by mounting your cylinder on a rod next to a speaker that is sounding a 60Hz frequency. According to him if a nail is suspended very close to the open end it will ring when the can vibrates. The nail acts like an amplifier.

So step one, and the most important, is that the cylinder regardless of material used is 'tuned' to your line frequency. If this step is not completed everything else is a wash.

So thats what he meant


Bless you core
you just saved me wasted work,plus you put this in a much brighter light
Ringing....................

WOW

Thanks
Chet
PS
YOu are IN NY Area have you seen his brand Beer in the deli?
I won't be in NY till mid week !

Screw Clamp

A screw clamp might make a good expedient ring to get started with. At least it would be an expedient method of finding the inside diameter for our ring.

This latest information was necessary and helpful.

[RAMSET]

Thanks for the help

If you can believe this ,No beer or any alchohol for sale in Connecticut
on sundays [like the dark ages]

I'll be playing with a coke can today ,as EXnihiloest pointed out on the other thread Acoustic resonance "sonic" water heater "working replication"?
The materials involved will creat a "tolerance" issue [flimsy]

As MonsierurM pointed out we can try "MiCa" insulator?[insulator shim stock]

And as Core pointed out water in its purist form is an insulator,so the specific gravity will be an issue with the "gap"
Meaning HIS Gap in Serbia Maybe Different than My Gap in Timbuktoo.

Such is life.....its easy enough to play with!!

Standardized Rim

It's probably standardized rim. Thanks!!

0.5L cans are very popular in Europe but if that must be particular beer with not standarized rim - it would be hard task !
