@ Jeanna,

Great jim,
Of course I was not referring to you being missing. It just seemed that everyone's enthusiasm dried up.
you might not be around then.

thanks,
jeanna

Understandable about the enthusasm drying up, no worries, I'm not letting it go to rest.
I didn't think to include my single cell plate assembly in the readings.
Here they are
Voltage = 0.44volts

OK I have a MOV file for you to look at
1st part of it shows the waveform from my series setup
2nd part shows the waveform of my single cell setup.

@ Jeanna

I am still here lol ....I just been really busy , will have some more readings tomorrow ...

I have 2 setups in the ground
2 setups in planters ....

I haven't given up , aint planning on quitting on it either ..
This stuff excites me , it maybe low power but hey its pretty much free power...I am planning on doing a stubblefield coil to soon ..

Thanks Jdcmusicman

@Jeanna,

Please do not get discouraged, only the garden is drying up not my enthusiasm. Lots to do before winter arrives. We need some way of having a synchronized collection mechanism so we can compare everyones data. I have been feeding the EB into the computers sound recorder and have been getting some interesting data. Feeding the voltage through a 1ohm shunt then using a 30db gain filter you get some strange current readings. The current has spiky square waves throughout and sounds like noisy motor or electrical equipment running, popping/sparking on and off. Voltage appears as a distorted 60hz AC wave and has that distinctive 60hz hum when you listen to it. I have the files but they are too large to post, compression would degrade the signal(32bit floating point).

Not sure if you have the NEETS manuals but Module 9 is a good read:

OK jdc and DreamTB, I will do my best to not be discouraged.

I am sure the design must remain simple.

The idea to run it through your computer is great for you to do.
It is kind of like my stubblefield gens on the other EER. I have a plain one and that is what I report here. The other is interesting if I can explain what it means to people, so really it is for me and my research.

Here is the problem as I see it:
If it is a difficult thing to get 12 people who claim enthusiasm to pound a copper pipe and a zinc roof nail into the ground and stick wire on either end and submit a daily reading... which it has proved to be, how on earth do you expect them to do something actually complicated?

I will try to keep my chin up.

Thanks for coming forward today both of you,

jeanna

Good idea this, please let me know more about how you record your data.

A quick circuit too please, showing the bridge etc.

Wilby has been making a web page to display our readings in real time, and I need to get back to him shortly about this, it might be far easier to send an audio signal than a video signal, it uses less bandwidth.

I have a registered copy of NCH Wavepad, I assume I could use to record the waveforms in real time, I havent done this before so I will check it out first.

I will make up the circuit below and get back to all shortly.
