    Magnetometer... help?

    >what I really want to do is ( when I get the time ) build the best type of wreck detector I can. ( I havnt got the time to try them all )


    I can't help you here - I have no experience with towables. You might try Tony Wells at SearchMasters.


    Also, if you're interested in a towable PI unit Eric Foster has the Towtec board available pretty cheap. Search back through his forum for info.

        Re: Torsion Fields

        hi sam-

        thanks for the responce.kind of thought you might havelooked a little at this stuff...just read of it recently on another forum (mentioned there) andlooked at this some---of coarse more ? than answersare presented...also most of the studies are in/fromrussia...a man can study sand for a lifetime--andknow nothing about sand...interesting though...(glad you still around)

        reg-rick

        >I've seen some of the references, and even brought up a couple of the sites, but really haven't had the time to study it in any depth.

        >One site indicated that it was not a particularly new concept, so perhaps it's already been "kicked around" some by the scientific community, however, I'm not aware of any other site references --other than those on the "Pro" side of the concept. (That doesn't mean there aren't any out there.)

        >As I get more time, I'll try and poke around and see what I can find out, from sources other than those which we already know about.

        >Carl and Evan may have some info on the subject also, and will share it with us.

        >Naturally, there are a great many theories and hypotheses out there, and some may be able to be advanced to axioms, with the correct amount of testing and analysis. However, just because something sounds like it is already validated, because of the terminology associated with it, doesn't mean it IS validated. We have a shining example of that sort of fallacy in a very close neighbor of ours.

          Re: Torsion Fields

          Hi Sam and all,

          I did a little checking on the torsion field sites, and I'd have to agree with Sam, It looks like the original basis of all the commotion was an old Russian paper which has been elaborated on and made into another "cold fusion" debacle with promises of unlimited power, warping spacetime, perpetual motion machines, etc.

          Some of the postings of pictures of field maps of "torsion fields" are nothing different than the magnetic field patterns one would expect from the way they wrapped wire around the ferrite toroids. Also, their point of getting the "aether" or "ether" spinning...., the ether was a ficticious entity created in the early days of E/M theory to explain wave theory. Since it was determined that light behaved as a wave, and all other "waves" (sound, water, etc.) could only travel through a medium, the "ether" was created. It's existance has been disproved by a battery of experiments over the past decades.

          It's very similar to the gravitational constant that Einstein created to explain that the universe was constant. When his calculations showed it should be expanding, a "fudge factor" added. He admitted after Hubble showed that the universe was expanding (red shift) that the gravitational constant was the biggest mistake of his career.

          Anyway, the aether is gone, and has been for many years. The flat earth society still exists, and people will hold onto their beliefs, regardless of the facts.

                  Magnetometer... help?

                  Back in 1970, I almost built the Leslie Huggard PM - I was 12 at the time... ;-) Nice to see that article archived - I almost considered updating the principle as I now work with DSPs etc.

                  Now, I'm looking at Carl's design. How sensitive is it? What will it give me that others won't (apart from ferrous selectivity)?

                  Thanks,

                  Nick

                      On the home page http://www.thunting.com/geotech/ under "Tech Forum" perhaps?
