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.

Best Regards,
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 ?

[Slovenia]

Thank You

Your welcome!! Thank you for being such an integral part of this too!!

@ Slovenia Thanks for the answers!! This just keeps getting better!!

Can't watch now I'm working

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...............

I've just been playing with the Joules/sec and watts to amps conversion How do you convert Watts to Joules? - Yahoo! Answers and although my meter is aged and not calibrated,and a thing bubbling in a jam jar by my computer is certainty not laboratory conditions the maths would seem to indicate that a constant draw of at least 2.5 amps should have been required to raise the temperature of that water up to boiling in that time period.
Still I could well be in error or my meters incorrect I'll await some supporting evidence or duplication.
and go and scribble a bit more....

What is the can parameters you are looking for 60Hz current there in USA ? Exactly what length you need ?

I have also a bit of problems to understand how you would like to step it up from 110 to 220V.After using transformer how to find which is hot connection and which is neutral ?
I have checked my 12/230V inverter and seems that both outputs can light neon :-( No neutral ?

Hot Connect; Neutral Connection; Can Length USA

Hi Boguslaw,

Connections:
The hot is the can and the neutral is the ring.
Can Length USA:
The can length needs to be 200mm in length and the diameter should be as close to 65mm as possible.

red bull 20 oz

All,
I just got back from town with a 20 oz red bull can. Measurements as follows....
Diamater....2.598" __ 65.98mm
Length........7.663" __ 194.64mm

So, its a little to fat and a little to short.
Dia. Measurement was taken at middle of can. Very top and bottom are 7 thousandths bigger.

Length was measured with can laying on side from top to bottom.
....can is full ,unopened.
We will lose .230 when we cut the bevel off like Slovenia said to. That puts us at 7.230" as a length for the can IF we cut it just right. That's my starting point, ill let ya know!
Cheers, Jason

60 hz length

My 20 oz. Red bull can is now 7 1/8" long measured from the bottom, and nail is vibrating off of can at 12 inches playing 60 Hz. Test tone off of internet. The nail isn't super bouncey like it was last night with the other can, but I think I'm getting there! The nail don't bounce when I try to play the natural hum of the stereo to it. Chet, you may be right about the manufactured tones not being the same as your mains tones.

All,
I think the can is down to a hair under 7 1/8" now, just measured with a regular tape, instead of calipers. That translates to about 181mm. length from bottom of can. I will try to video it in the morning to get ya alls opinion if its tuned or not. I kinda feel like it could be better. When i started out with this can, i left the bevel on it just to try, and could not find a freq. to make the nail move. So i cut bevel off and started sanding can, 7 3/16" @ 100hz. made nail move. so it dont take much to change the can.
