Hi all have been reading info on this site the last number of days it is great. I have been  using

copper and galvinised steel for my electrodes multimeter back this way is analog also  have been

using a bit of flat galvinised tin plate for my negative electrode I seem to get a small improvement in

the voltage not much will no more when I get the digital meter.

Electricme,

   Thanks for the welcome and the info. I am looking forward to see what you described: since I am working with very low signals I wasn’t able to see anything.

   I also reached the same conclusion about the oscilloscopes connected to the mains power: they will always show the AC component in small measures. That is because we reading something connected to the ground, and the power supply also is referenced to the ground.

To overcome this I am making an amplifier supported by batteries, if we have the signal at Volt level, then the AC component becomes too small to hinder the measures.

I was also looking for a PC oscilloscope, the kind that stores internally the measures and then transfers to the PC by USB. There are some cheap ones on ebay (about 50 euros), but they will only go for low speeds (100 kHz). The good ones are expensive (but still, a lot less than an oscilloscope).
I have access to a lot of measuring equipment in my job, and they are ok with me using it because I am careful with it. But I needed something connected to the computer for another project (the alkaline battery recharger), and it also would be a good help to register the waves we are getting in the earth battery.

Regarding those high frequencies pulses, I found out that they came from my Wifi router. The earth is not picking up the signals, but the oscilloscope leads are working as antennas. Maybe I should bury the oscilloscope also… Not sure if my company would like that  .

@ nightshade,
Welcome aboard,
I have thought of using "tin" also with my copper pipes, this is a difference on the periodic table of 21, but then again I think if you used a "lead" plate, you would get a better result, this being a difference of 53 points on the periodic table.

@ Ram,
When you say you are making a amplifier, would I be correct in thinking the probes plug into the front end, with the output to the Y input?
If your idea works, I wouldn't mind making one here, just email me the circuit, it would be good to compair results.

Last night we had a couple of storms here, I made a point of looking at the "analog" gauge (in my kitchen) which is connected via a long lead outside to the Carbon and zinc setup outside, (im a lasy coot, dont wanna get wet too  ) the needle went almost fullscale for about a 1/2 hr, then retracted to about 1/2 scale as the earth was saturated, then htis morning it showed a bit higher scale as the ground dried out.

I must calibrate this thing soon, put a "range" switch in it via a few resistors in series with the MC "moving coil"
But first I have to repair my adjustable power supply, the primary in the T1 has let the smoke out, and it don't work anymore   

cheers all
jim

thanks for the welcome there electricme and  thanks for the info on trying lead that would be

interesting. well went back out again to day and used a different metal  a graphit rod for the positive

from the local arts store. but I left the negitive rod as tin the setup was from south to north north being

A graphite rod and south tin. these were spaced 1 foot 21 inches from each other I obtained

readings on the multimeter of 1.13v  but very poor current next I will try that lead and see the

difference.
