Testing Help Needed
At present, I don't have a PI MD, (yet). But there is something I would like to find out about them and I was wondering if someone out there could do a few simple tests and report back on the results? Small pictures of the different readings from the oscilloscope would be great.
In order to do the tests, you would need the following items:
1) a digital camera (to record the different signals of the oscilloscope),
2) a PI MD,
3) a dual trace oscilloscope (which would be connected to the PI MD to capture the PI's signal as the different materials are passed by the PI MD's coil),
4) approximately equal sized pieces of; gold, platinum, silver, copper, iron, stainless steel, aluminum,
5) plastic or styrofoam jug or other container, water, salt, (ignore this if your coil is water proof).
When doing the tests metals, or minerals should come within detectable range and be held at equal distances to the coil surface. The first test should be a "dry" test in open air with each of the metals and minerals, (except for the salt), followed by a "wet" test done with the same materials in water, then a "salt water" test with each metal, or mineral submerged in water containing about 3.5% salt. (DO NOT do the "wet", or "salt water" tests if your coil is not water proof.)
I doubt many people have all these items at hand, but testing as many as are available would help. If a person also has a sample of sand containing black sand that could be tested with the gold, platinum, or silver, that would be useful also.
The purpose of this test is in relation to the potential development of a discriminator for the PI MD's and a GeoTech project with that aim in mind.
Thanks in advance for any help you can provide.
