You are absolutely Correct 100 %
This Resistance heating will manifest in the presence of two spoons
or whatever one chooses!

The real thing to measure here is Time to heat,and once we get a few replications going ,we can establish a test protocol for this.
We have a friend here "Tinsel Koala" who has assisted many times with measurements.
I will not pester him until it becomes obvious we have something special going on here!

Thank you so much for your contribution

Gotta get back to work...............

Can Tuning Fixture

Boguslaw,

I can post a pic on tuning soon. The can should be vertical during tuning and free standing slightly touch the nail is good. The nail should just be barely touching the can and not forced into the can. The nail just needs to touch the can ever so lightly. The tuning seems to work better when the can is free standing and not viced up on a platform.

Slovenia

Slovenia, can you post any picture how is can placed against nail ? is that placed horizontally or vertically ? should it be mounted in final location or just placed in vice for testing ?

[boguslaw]

I cut 1/2" off of length and no longer resonates at 40 Hz. Did seem to want to shake the nail a little at 30 Hz. Must be between 30 and 40 or lower. No reaction at above 40 Hz. Time for a new can..............

Right.Do not dring Red Bull too frequently though ....

Validation

Jason
You're validating the PDF tuning protocol with your Findings!!
Specifically that we in the USA need a longer can for this device!

This is very encouraging ,as some have felt the can will not ring at all,
You have shown it rings at different lengths to different frequencies .
{quite readily it seems?]
Some felt the signal much to big [ELF] to be able to tune to this can??

This is wonderful news!


Thanks

Bevel Query

You want to remove the bevel. The top of the can needs to be able to vibrate around and the bevel makes it to rigid. I asked Mr. "C" about this. Thanks for sharing. It's great to have you on board with us!!

Also, when I cut the top off the first time, I cut the bevel off,where it gets narrower to go to the lid. Ya all think we should leave the bevel on? This may make the can sturdier. Maybe I was supposed to leave it. I think I will on the next can. It can always be cut off. More later!

ringing at 40 hz.

Ok. I have been playing with tuning just to get a feel for it. Seems my can is ringing at 40 Hz. The nail bounces off can at this freq. At 12" away. The can is roughly 5.880" long from the start of the radius at the bottom to where I cut it. My stereo will hum like a guitar amp if put in video mode with a cord plugged into the mic Socket, so I suppose that is 60 Hz. It will even squeal like hell if you turn the volume up . Anyway i was sanding on the can and actually sanded a hole in it where there was a slight ding. So I had to cut off 3/16" of length. Still couldnt get the nail to move so I went to WWW.testsounds and started to play different freq Through my stereo to try to see where my can was as far as freq. 40 Hz got good results. 50 & 60 hz. nothing. Now since the can is too short, I'm gonna try cutting some more off to confirm that it will lower the resonate freq. Of the can. Slovenia, those 2 pictures were the only ones I took. I will take more and get one of those tinypic accounts for the next can now that I got a feel for what I need to do. Also, when I cut the top off the first time, I cut the bevel off,where it gets narrower to go to the lid. Ya all think we should leave the bevel on? This may make the can sturdier. Maybe I was supposed to leave it. I think I will on the next can. It can always be cut off. More later!

Re: Tuning Question

Hi Chet, (Be Glad To.)

1) Can you run thru your current understanding of Tuning protocol??

Response:
The main tuning thing with these cans I think is the length. The skins are so thin, it's hard to take off much more material without really messing up the cans. Anyway, I do know that the paint has to be removed from the area where the can is going to be riding next to the ring. This will make the can conductive to the ring. Mr. "C" said that the top of the can only needed to be sanded and at a bevel to sharpen the top edge inward. Initially Mr. "C" said to cut the can to a length of 150mm and then later to 200mm for USA. I haven't had any more clarification on that lately. So, I'd recommend cutting the can to 150mm length to start with. Then sand the top outer edge of your can taking great care not to deform it in any way. It's easy to deform it. Once you're happy happy with your sand job and length, fix your can to a base to stabilize it. Now, hang a very fine thread with a small 25mm nail from the ceiling and/or other support structure. The nail needs to be on the outside opposing edge of your can away from the 60 hz sound wave you are going to fire in the direction of the can. The nail is only to slightly touch the top edge of the can. The purpose of the nail is to act as an anvil against the can so you can hear something when the can is forced to vibrate. Without the nail, it would be much harder to hear anything. You are supposed to sand the can until you have the optimum ringing ability. When the can is tuned, it should vibrate the nail really well. If it's not vibrating the nail you either don't have the can tuned well or you don't have it cut to the right height. Take your speakers and point them at the side of the can opposite the nail and from approximately twelve inches away. Your can should vibrate the nail if tuned properly.


2) One thing I am fuzzy on is Professor Savic says the Pendulum should vibrate as it leans against the thinner end of the can??

Response:
No, it's actually the can that vibrates against the nail and the nail make a slight chatter on the edge of the can as the can vibrates to let you know the can is vibrating.


3) Is the Pin and pendulum acting as a "Pick up" ??

Response:
Not to my understanding. The can is picking up vibration and vibrating against the nail.

4) Extra sensitive vibrating before the can actually does??

Response:
The can needs to be sanded and cut to the proper length or it won't ring at 60 hz.

5) I'm confused on this point and it does seem critical ??

Response:
The can needs to vibrate at 60 hz for USA and the nail allows you to hear the can vibration. There's slight ringing as the can vibrates against the nail.
