Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[jeanna]

MMMMM this is a funny thing,
After yesterdays foray into coilguns and thoughts about same, I had an idea. 

I was seeing how it is possible to augment what is in a wire or maybe the circuit? by wrapping another secondary coil around an iron core that already has a primary and a secondary. I guess this idea isn't new, the flash power augmentation is based on it.

(I am thinking it might help to get that spark.)
So, I decided to wrap another secondary around the Fe10 wire. (I could have used the 6 but in the case of this coil it is crooked and the 10 is a good subject for wrapping.-no other reason for the 10)
BTW this coil is still moist from some tests done a few days ago, but I added no water today.

I measured ohms volts and amps before and after. In the following readings the probes are on the cu10 and the secondary, which is wrapped around the Fe10. (the cu 10 or 5 to this secondary is the only place that gave a reading- on this new secondary)

What happened is:

the dc voltage dropped (from 132 to 87mvdc)
(The vac are not within the resolution of the meter.)
The amps drop while I read them so the range of the coil without the 2nd secondary were
1.09mAdc to 0.97mAdc and they went UP to a range of
1.70mAdc to  1.13mAdc

now that is cool. not much but up.

So, then I fired up a supercap with 2.5 volts and shorted it across the 10's.

And in that bittersweet arena where you don't know if you had something until you lose it... It is gone.
There is nearly zero on every reading except resistance.
In the last 30 minutes the amperage has risen to 20 uAmps.

bitter but sweet ,

Edit: About 1 1/2 hours after that last post, I came back into the lab  and put the probes back onto the same wires and the whole thing was restored.!!  Then before my marvelling eyes, the reading dropped then returned then dropped again. It cycled from hi to low 2 times in maybe 5 minutes, then cycled 2 more times but much slower, maybe over 45 min to an hour. I was looking at voltage but when things got slow I looked at amps too and they were running parallel as far as I can tell.

I am going to rewind this and put more winds on it. (this one has about 50 in 4 layers.)

More next time )

"I spent today studying coil guns. It seems that it is the perfect study for where I am in this NS coil design."---figured youd like it

Sorry i didnt warn you better about being carful with the photo flash circuit.Ã,  Its given me quite a jolt before.Ã,  The 300 v off the cap isnt that bad it will hurt a little and startle the hell out of you but the 4kv from the flash side.. will make ya jump back and possibly skrew with your nerves for a sec.Ã,  Dont complet the circuit with you handÃ,  ;DÃ,  Anyways soldering connections to the little board for the charging switch and the rest is the way to go so as to not get shocked.. I found just the camera flash boards for about .79$ on http://www.goldmine-elec-products.com/prodinfo.asp?number=G15800Ã,  Direct link. The last coil gun i built i put 3 of the photo flash caps the 300v 200mfd in parallel to give me 300v @600mfd of storage.Ã, Charged them off a single photo flash board. It will send the head of a roofing nail through stryfoam or cardboard... Pretty cool. Gives you a better respect for electricity too.. A double A battery can be deadly , well not really but the energy stored in it is much more than one would think

Hi people, this is my first venture in your section on earth batteries so I hope it ends up in the right section.

I have been browsing the last few days and have noticed a very common problem, where can one access carbon rods, stainless, material etc etc.

CARBON RODS
Well I once took apart the insides of a 6 volt lantern battery setup, these are the biggish heavy square ones used in a plastic lantern torch, they have the spring contacts on the top of the batteries.

The battery has 4 dry cells which are a bit longer than the old D size battery, just peal away the tin cover with pliers, then separate the battery cells, cut the base of the battery off with a hack saw, tip out the black stuff.
You are left with a zinc outer casing and a central carbon electrode. (ha ha wear gloves) pry out the carbon electrode and scrape off any gunk sticking to it. There is a nice shiny top cap that one can use to solder a wire to access the power coming from the carbon electrode.

ZINC
No doubt the zinc casein could be put to another usage also.

Another way is to look for carbon arc electrodes that I used to use in the cinema projectors lamp housings, there were long and short electrodes, they had a coating of thin copper plate which can be peeled back with pliers, if you are careful.


OK hope I solved the carbon access problem.

By the way, I live in out back Australia west of the great dividing range, and I also read 1/2 a volt on the copper 1/2 " 4' pipe I drove in the ground, which is connected to a 24" aluminium tube I took from my vacuum cleaner, ha ha.

I also read AC voltage as well as DC.

MAGNESIUM
Haven't tried this yet,
Another place to find Magnesium is from a broken MAG wheel rim, try your local car wrecker, I'm sure he will be only too eager to let you have one for about nothing, it's no good for it's original purpose. Every nowandagain I see one at our local dump, going to keep my eyes peeled now for more.

STAINLESS STEEL
Try your local scrap metal bloke, they always have the stuff, ask for old sinks you might get it cheep.

LOCAL PAPER
Put a advert in your local rag, maybe someone has metal junk they would be happy for you to take away for free.

SOFTWARE
Well I think I will make some program .EXE it will be nothing fancy, just so I can record my findings using various metal electrodes, what does what, which is more efficient etc etc,

Let me know what you think by sending me a message to, jdudgeon at big pond dot com . just leave out the at and replace the dot with a dot, join up the big with the pond. Type EPower in the topic or it will get tossed out.
if I get enough responses I'll do it for zilch

Hope I have been of some help

Jim

Your always welcome to stay here and replicate wtih us for ZILCH too...

Joe,

i took some bismuth and layed slats of it under the end of the barrel just enough to prop it up and it gave me added range and velocity, as well i Plugged my opposite end the end i wasn't shooting out of with bismuth.

I forgot to ask you before, Where are you getting slats of bismuth?

Some guy on the net describes melting bb shot into a form. Is this what you are doing?
