@ Jeanna:

Great job with your portable scope there.  From what you have reported, as well as others, it appears these EB's have a mind of their own for both frequency and output.  Soon, I will scope mine and see what happens.   Nice work.

Bill

Thanks Bill,

What I am wondering is if that bit with the 2 similar metals is the AC/Random Current in the earth. If that is the number the scope is picking up over the level the dmm picks up, it might just be the true ac of my back yard.

Yes, the other day I saw 0.664volts on the dmm, but the scope saw something similar to this... something in the mV range at 2.4MHz that day.

It isn't enough samples to make it a rule, but I am going to test this a few more times.

I got some germanium transistors today from the gadget. I tried one out on the breadboard with the Berry. ooooweee. It is nice to have it start sooo low.

Now, I need to make some good probes for my EB. 0.000v is pretty darn low if you ask me!

Jeanna and All

The discovery of 2.5Mhz on the EB if of major importance.  It has been a long time since my basic electronics circa 1957, but you can do many things with AC.   

Make a tunable series resonant circuit and a parallel resonant circuit.  Make them tunable around  the 2.5  Mhz range probably with an old variable inductor used in old ham transmitters. Or, maybe a variable capacitor out of an old radio?

A series resonant circuit will amplify the amps of the ac wave and a parallel resonant circuit will amplify the volts of the ac wave.  The multiplication factor is limited by the Q of the circuit.  One way to get Q up is low resistance wire.  Some of the old variable inductors used high silver content wire.  These can be had on Ebay.

The multiplication factor normally can be anywhere from 50 to 200 times the input voltage or amps.  That means instead of working with .6 volts you can be working with 30 to maybe 100 volts?

Connect the series res circuit to one leg of the EB and see if the amps is multiplied?

Put the parallel circuit across the two legs of the EB and see if the volts are multiplied.  Maybe the two could be mixed together somehow with two EB's and get a significant gain of power.  With higher voltage, you can now extract the power through a standard full wave bridge rectifier instead of trying to capture small amounts of voltage with a JT?

A resonant circuit will work like an energy pump.  As each cycle of the earth energy hits the circuit it gets rebounded back much the same as pushing a swing to get it higher and higher.  Maybe this is how Stubblefield did it.  In some of the old photos it shows the cords are not straight, but long coils (inductors) of cotton insulated wires  This is connected with the capacitance of the EB.  Tuning could be as simple as uncoiling some of the coils on one end of the wire.

Just some ideas that might work?

Hi Tishatang,

Thank you for that thoughtful reply.
I think I will copy your reply and study it since I need to learn a bunch of practical things before I could put those pieces together.

I would do all except the full bridge part since my interest is to take advantage of ac and learn about it at the same time. I am not interested in rectifying it back into dc as I believe that creates a limit to what can be used. - not that I know how, but it is what I am exploring.

On the N Stubblefield topic, you might like to read what I said in a post about 2 months ago on pirates stubblefield thread. It is long and I won't repeat it here. Briefly,  I think he made a galvanic battery augmented by earth currents that  charged a joule thief which was switched on and off by a spark gap into the ball that is often shown at the top of his devices. He always seems to have 2 devices connected together.

thank you,

Hi everybody,
I fixed the loose connection today. I have 0.818v on the EB with unknown shiny yellow metal (au?) from thrift store cellphone on North + and dipped zinc nails on South (-).

I took some scope shots and If I get it all on this post they go from farthest away (lowest resolution) to closest and highest resolution. I took a movie but it is 885K so too big for here.
