Proton Magnetometer

Here is a slightly compressed pdf made of these images for easier reference.

Oh, thanks Davor, I need to learn how to do this.

It is easy, just download PDFcreator, and install it with images2PDF option. PDFcreator installs as a PDF printer so it is handy for creating PDFs from just about anything that can print.

Thanks for the tip, I will apply it at the next opportunity.

Another alternative is to download either OpenOffice or LibreOffice. Both of these can generate a PDF file directly using File > Export as PDF.

Today I finally got one time to do the test field of magnetometer, first impressions were good,
no noise, opening the sensitivity to 70%, (even without the capacitor mentioned above) using
an iron bar of the 1 kg, i obtained a signal characteristic of precession (sound trembling decreasing),
however very low, with 65% sensitivity, towards west to east.
I do not believe that there was metals in the area, but the high tension line passing parallel at a
good distance but not enough must have affected the outcome, I need to go to a rural area.
I can't still completely eliminate the "snap" from the switching relay, I do not know if it will be possible.
Anyway I liked the initial results.

Hi Baterista.
What are you mean exactly with the "I can't still completely eliminate the "snap" from the switching relay".
My magnetometer does not have good sensitivity.
Do you know if there is problem if i"ll use Deionized water instead of distilled water?????


Regards

Hi Geo, I meant the noise switching (on / off), produces a "tac-tac"
there must be some component that can decrease or eliminate the effect spark switching in the circuit.
As for distilled or deionized water, I read somewhere (I need to remember where) that the ideal would be distilled water.

Hi all. Have been unable to get ferrites for Huggard's mag', so have put on hold. In the meantime, have built and tested Phil Barnes design, but have not managed to get the signal through, although there is plenty of gain ,and the amplifier is stable. I have the thought that the front end needs redesigning or a proven one added.

Hi.
I have similar problem with Huggard's magnetometer, received signal very low, only one beep...
Maybe this winter to construct something else...

Hello, Geo, I did some experiments in other more isolated location, and obtained a slightly better result, I'm building
other coils for testing, but for lack of time (it seems that every day it gets worse) everything is slow, anyway,
when I have news, I'll report.

Hi magpie, usually the critical point of these projects are the coils, try to build another coil greater or lesser resistance and inductance. Also check the orientation of the windings. Best regards.
