Earth Electrical Energy Datalogging Experiments

@All
Just after I took this photo the old LED decided to burn out, I was sorry about this, the LED had done me a great service in the past.

I am usually very careful about driving them to extension.

Hi everyone!  (Yup, a real post and not a pm, Jeanna)  As you all know, I am very determined to read every word of a thread so as to better understand it.  I just finished reading this thread.  Very interesting!  I would like to say something to Jeanna although it refers to a past post a few back...  Don't give up and Do NOT get discouraged!  If it were not for YOU a lot of threads would dry up.  You keep it going, and you make it interesting for the rest of us.  Some of us may not be able AT THIS MOMENT to do any oscilloscope readings but perhaps later, who knows?  We still need YOU and the others to continue what you are doing.  Some days are slow...just as in all forums...and some days all is clicking so fast we cannot keep up.  Well, I still have to finish my reading of the Joule thief thread, and then...watch out!  I will be going back full time to my EB making and then some.  You know I have most of the parts needed.  Just had to deal with health and family issues, and reading assignments.  If my eyeballs don't fall out, by the time I finish with the very long JT thread, then I will be a happy camper.  All the scope shots you have made are NEEDED.  You can see that there have been many viewings of the posts you have made and they are not for nothing.
I have seen many great ideas that I have to add to my list just by making myself read every word.  I suggest any new person who comes here, should take the time to go back to the beginning and read all the way through.  You will learn a lot, not only about the experiments, but also about the people of this forum.

@ protonmom:

Well said.  I agree 100%.

I also agree that everyone should read the previous posts, not necessarily before posting themselves, but for a better understanding of what has been done before, what worked, and what did not.

I have a great respect for you for doing this.

Good work! I expected more Ma and the large voltage drop with the Led load is weird even at 160 feet.

Good work! I expected more Ma and the large voltage drop with the Led load is weird even at 160 feet.

this is 'normal' when you connect a load to an earth battery, and measure the output terminals, because it 'draws' the voltage from the circuit. also noticible is when you disconnect the load, the voltage gradually rises again.

one thing to try is place a potentiometer (variable resistor) inline with the diode, and adjust it to the minimum level required to turn the LED on. This should decrease the draw on the circuit.
