A couple other observations I forgot to mention.

The setup is of course, Freq generator outputs two leads to Freq amplifier (I built my own to get started) which has two output leads of course.

Per your instructions, one lead goes to the contact point on the crystal. In my case, I did wrap a Mobius coil around it though I suspect, and what you have been saying, is that this may not matter all that much. So far at least, that is what I am seeing.

The other lead, dangles.

I connect the volt meter, which is nothing more than a cheap-o, actually free giveaway from Harbor Freight. A Cen-Tech. These meters are a dime a dozen. But they work. So I connect the negative lead from the meter to the free lead from the Freq generator/amplifier. The positive lead connects to........... me.

Here's the additional interesting stuff. At least to me. I've been taking the lead connected me and placing on known acupuncture points. So far have experimented on the hands and wrists. And not surprisingly, different contact points produce varying measurements. Brain. Endocrine. Organs. Etc. The points related to the brain respond with the highest measurements. Am still fiddling around with other points.

But there appears to be a corrolation. I found that pretty cool. And I also know there are certainly many people and gobs of science that could produce scads of information about this. One person that I have become very interesting in is Dr. Jerry Tennant from the Dallas, TX area. He has assembled a body of work that has culminated in a device called the Biomodulator and a book titled Healing is Voltage. Where he applies science to points on the body and is able to measure voltage and frequencies, which is where I got the idea to poke around with my little voltage meter.

Anyway, thought to add this tidbit. That not only am I part of a closed loop in a circuit of energy involving a Frequency generator and a crystal, but that I am discovering related points on the body that correspond to points inside the body are returning varying measurements.

I just think all this is pretty cool.

Oh, and in the Department of Useless Information, but I find personally a coinky dink, I live about a mile from where Tesla performed a lot of his experiments with energy. And that has absolutely nothing to do with anything, but what the heck.
