grounding suggestion

Gents {and Mrs db]

I want you to understand something ,you can play with this very safely!!

Here is a technique for doing a good ground [extra ground].
I take a standard grounded plug I wire up only the ground [the other two poles are empty]
I plug this cord [25 ft ... or whatever] into another grounded outlet close to where I am working I CHECK THIS GROUND with a meter probe the hot and it lights .....I have a ground .... no light [or reading ] NO GOOD!!

Once I have finished my test run ,I unplug Professor Savics Device
Take the plugged in ground .... drop the end in the tank ...Take My meter [make sure its on and set properly] ... remove the ground lead from the water
clip one wire to my ground place the other meter lead in the water .
No reading at all ??
Set meter to DC
Still no reading??
Your water has no charge remaining.

Remove device............

You can of course leave your ground probe in the water at all times [connected to the neutral on the device or ground post in the water].

I er on the side of caution ,as this device is not supposed to do what it Do!!


Thanks

Hey Chet.
I have been using this site Stereo System Test & Analysis Tones by Nino B. to figure out where my cans are ringing. I hook headphone jack of computer to a stereo with an aux. Input and play the tones that way. I think we talked about how digital 60 Hz and mains 60 Hz probably won't be the same, but I figure this is a good place to start, at least you can try different tones to see where you are starting out. For example......my last try tuning, the nail bounced a little at 70 & 80 Hz. A little more bounce at 72 &78 Hz. At sweet spot (75 Hz) nail bounces 1/4 to 1/2 inch away from can and I can hear nail dinging off of can. That's how I figure can my can is at 75 Hz.
Now if I unplug the computer from the stereo and leave the aux. Input option on, turn the volume up a little, there is a hum that comes from the speakers........just like a guitar amp sounds before you plug in the guitar..... I'm guessing this is the sound of my 60hz mains.....so far I haven't had any luck tuning.still trying as time allows........Im going about tuning the best I know how...if ya find a better way please let me know!!
Good luck!!! Jason

speaker HUM

Jason
Speaker HUM is what we need,I just found A PA [public address] Amplifier
And Microphone in one of the storerooms here!

Now I'm looking for a speaker ...

One of My sons has A small amp he is supposed to get me But its at some friends house??

I want to learn how to do this Tune ,when I was younger I played around with Ham radio, Tuning is Critical to proper transmission [and receiving]!!

Gonna Be fun !! Sensitivity is also critical [the fine tune]!!
Meaning ,,Getting the Pin[Nail] to vibrate at lowest possible Volume is the Best Tune [most sensitive]!!
I am anxious to see what An E L F transmission to A tuned receiver set to resonate a huge flexible tube Underwater ....Can do?

Good to hear from you Jason
Thanks

IKEA Thermos (Factory Made)

Hi Chet,

I can't take credit for the IKEA flasks in the last two pics I posted. They were from Mr. IKEA himself, somewhere in Eurasia. My flask turned out pretty good but I don't have a belt sander yet, and my hand sanding job isn't near as good as his. I'll show mine soon. I didn't want to take someone else's credit. Thanks!!

Best Regards,
Slovenia

Our friend daemonbart is an extra lucky man .He shared in the beginning of this thread that his Woman contributes and encourages his working on this!!
I am quite Jealous ....
As you know Our wives can get pretty frustrated with this and the financial as well as emotional burden it can place on our relationships!!

Quite jealous indeed...............

I hope this device will be the one to change that ,once I start to keep her warm and toasty ??

Anyhow thats Mrs.db [the only girl experimenter here ...so far]

If they find out it keeps them nice and toasty we'll probably have a wimmin problem around here!!

Thanks for fessing up on the ikea build... I was jealous there too
Very Nice indeed ,

I Remember Now

Hi Chet,

Very nice indeed. I remember now. My wife is about 10X smarter than me. If I was able to get her involved in this I could show some really quick results but so far she's not the least bit interested in it. She just about sent me packing today over this build. I have to show her some encouraging results very soon. She says to much money expended with no returns. I'm working on my flask trying to make it look more like that of Mr. IKEA.

Best Regards,
Slovenia

Diagram from Mr. "C" of tuning Setup:

[boguslaw]

I have proposition for somebody who has tuned can. I found this program very easy to extract sound from video. Free Audio Extractor,Extract audio from video,Convert AVI to MP3, WMV to MP3, MPEG to WAV AC3

I made video of my can (which is not tuned yet) when I strike it, then extracted sound and imported into audacity to get frequency spectrum.

https://pantherfile.uwm.edu/type/www...isAudacity.htm

However with untuned can there is not visible peak at 50Hz. I wonder if for tuned can we can see any peak at grid frequency , if somebody could check it with supposedly tuned can then it would be a good testing method as already mentioned on this forum.

Nice!!

Hi Boguslaw,

Good to hear from you again. Cool idea!!

Great!

Good idea, I will look into that

Also, send me your whish for stainless sizes so I can post it on monday, also transport free for you!

Speaker construction!

Hi, some inputs and tuning Ideas:

During Speaker construction, the mechanical resonance of speaker cone need to be lower than the playing resonance. Freq under mechanical resonance will be distorted and low powered while freq over mechanical res will be almost same power and quality as if you play exactly mechanical res freq From sound engineering book, printed 1960´


I rather tune can to resonate below grid freq instead of higher freq of grid!

Genius, it would make sense if you take into account that as the heater is being used it would "deform" and actually settle in a higher freq than initially....a new guitar does not sound the same as an old one

[boguslaw]

At first step I would check beer can with cut off rim, then I will cut the "bevel" area looking like a open cone.I wish it would resonate at 50Hz without removing that "bevel" because it support stiffness to the can.

daemonbart,

Slovenia computed that for me (Thank you! ) and I checked it match my assembly very good too. It's 250.29mm X 5mm or better 251 mm long and 5 mm width strip.
