Stubblefield coils (bifilar) and speculations

resonanceman · May 19, 2008, 01:29:24 PM

I just had a thought about this low power contact thing

We don't seem to have enough magnetic flux to activate the switch .

but we do have enough current to charge a cap relatively quickly

why not make a real small coil .......and mount it on a flexable metal " reed "

then connect it so its magnetic field attracts the stubblfield coils magnetic field as you charge a LARGE cap .

It SHOULD multiply the effective pull that can be harnessed for the switching .......

gary

Edit

it might work to place a reed switch between the stubblefield coil and the small coil ..........or better yet .........place 2 stubblfiled coils " head to head " with a reed switch in between hopefully they will work in a " push pull " mode

I am not sure where the other end of the caps would be connected .

maybe to the opposite 10 of the opposite coil ........
I am allso not sure if the reed switch should be in between the coils and the caps ........or by itself

I have been thinking of something for a while

I have been wondering how Tesla Stubblefield and others of their time made the discoverys that they made .

Today we can measure voltage to a thousanth of a volt with ease .......
We can measure current to a fraction of a milliamp

All we need to do is buy a multimeter .

I really doubt if Tesla or Stubblefield could measure these things as accurately as we can today .

SO .......if they couldn't measure as well as we can ........how did they do the things that they did?

In my opinion they probably worked with larger " quantitys "

If they were studying resonnce they probably worked with farads .......rather than microfarads .

They probably worked with large caps and coils to understand the effect ..........then fine tuned the system to be more efficient and smaller .

I think about this a lot, too.

One suggestion made to me a long time ago was the hi impedance speaker.

It works every time. I can hear minute amounts of current or voltage. I am unable to quantify it except by comparison.

My speaker came from a modem, but you can buy one from RS for $5 or less. I soldered some jumper sized leads to either post and I can hear the power.

A 3 volt battery is noisy. The copper to zinc probe in the ground that was .7vdc I could faintly hear as a sound that came not from the zinc but over where the speaker was.

If I put this speaker on the cu to bolt it is clearly louder than from the cu to the fe wire.

I also heard they used a wheatstone bridge to determine what they had. I had to look it up. It is a modified compass/galvanometer. I have used that, only mine is very plain. This compass/galvanometer graduated into the ammeter, so it isn't too far off.

Well, Gary,
That is all I have found so far to answer this question.

Anybody else?

I just really want to know how anybody is planning to mount a switch. That is the reason I asked storre for details.

If he did it, he has dealt with the fact that it is already heavier on the top and has wires in the air and no platform to rest a switch. Little narley things like that.

I think with Tesla and Stubblefield they didn't have quite the same " laws "
I really think that the foundtion of the mindset that OU is impossible was put in place as Tesla was blacklisted .

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I can see how it would be difficult to mount any extra hardware on your coils

You might look for some kind of angle .... I was thinking angle iron would be ok ........but a strong non conductor would be better .

A piece of angle iron around 2.5 in long with 2 holes drilled in it that the right places would would make a pretty good clamp ....... just find a couple bolts the right size ........maybe wrap an extra layer or 2 or insulation around where the clamp would be to make sure it doesn't damage anything .

one of the nice things about this way of doing it is .......the clamp can be used over and over ........if things don't quite work out .
