Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

@ Paul-R,

I have just been taking a look at the Allegro web site about the A1301 and the UG
N3503u, they look like they have the same specifications, either one should do the job.

I suggest you hook either one up through a LM7805 voltage regulator, as their VCC specs are from 4.5 to 6 volts, 8 volts max, but I wouldn't want to push it that far into the hi limit end.

You didn't mention what application you had in mind using it, might it be for measuring the magnetic flux around the Stubblefield Coil?

If so, you might need to slip a 1n4048 glass signal diode on the output leg, between the 22k resistor and the meter, or the meter might swing back and forth too violently.

Jim:

You are one of the smartest folks I know.  Your new machine is yet another brilliant idea that you not only thought of, but built.

My Dad was an Engineer.  They actually build things and make them work and improve them.  You sir, are an Engineer.

Cheers mate.

@ Bill,

No, I ain't that smart, but thank you for the acolades, ha ha.

I am currently cutting down a steel work bench to lower it so I can mount my Stubbfield winder on the top, had a few "extra" bits and pieces to do over the last few days, I am fiddling around with at the moment though.

One thing I intend to do is make a Stubblefield Test Research Coil, screw a vaccuum cleaner brish disk setup to one end and use this to monitor the electrical activity as the coil bifiler section is wound at every turn, every layer. This should give me some idea when electrical activity begins and it's strength in real time, by hooking it up to a CRO and Voltmeter, amp meter and a "variable load".

It will take a little more thought but is dooable.

Thought this might be of interest to some.

It can be seen that in a nonmagnetic conductor like Copper,carrying DC, the internal field strength rises from zero at the center to a maximum value at the surface of the conductor. The external field strength decrease with distance from the surface of the conductor. When the conductor is a magnetic material like iron,the field strength within the conductor is much greater than it is in the nonmagnetic conductor. This is due to the permeability of the magnetic material. The external field is exactly the same for the two materials provided the current level and conductor radius are the same.

Thanks for posting this.
