@all

I have to remove two protruding axles, and cut off other larger sections, all necessary to get this Stubblefield winder going.

1641 = the offending item to be cut off
1642 = made a start, almost done
1643 = Done, offending item removed
1644 = Getting ready to remove one of the old end supports
1645 = Done, time 4 a cuppa T 

I was up untill the weeee small hours of the morning, Im tired so I'm calling it a early night
Catch you all tomorra

I have a technical question relating to the production of DC from a big transformer.
This question I am directly asking mw383 and tishatang for their responce.
but others may answer if they so wish.

Here is my problem.
I have a NiCAD battery bank setup on my side verrandah, it consists of 20 ALCAD MP 300 individual 1.2 volt cells
I have a old Lead Acid battery discharge tester which is designed for the 2 volt wet cells, not these 1.2 volt cells, but it can still give the Ni-CAD cells a workout.

These I want to drive my UPS which powers my PC and a range of other stuff.

A couple of these cells are rather low in output, although they do come up with a good recharge, but they don't hold their charge as long as the other cells.

What I think they need is a single or a couple of BOOST charges to get them going properly again, but I currently don't have a DC rectifier that is capable of handling the punishment I want to meat out to then for about 1 hour or more.
-----------------------

OK, I have a MOT where I have modified the Secondary output, I removed the original secondary winding and rewound it with 4 loops of the usual size lead that runs from the car battery down to the starter motor.
Now I have avaliable hundreds of amps avaliable, at 4 volts, but this is AC, not DC

Here is what I suggest to alter the AC output to a DC output, I have not tried this, but it stands to reason it will work.

If I place a heavy diode on one leg of the 240 volt input to the primary side of the MOT, would I get DC out, by driving the primary with DC pulces.
It would have to be of sufficient wattage to be able to drive the primary coil. What size should I use?



My thinking is, as the AC drives the MOT, the secondary reflects the AC sine wave in the output of the secondary coil.
So we get the same sine wave on the output of the secondary, albeit the voltage is much lower but the AMPs are much much higher.

Now, if the MOT primary was fed only the top half of the 240v AC, then the output of the secondary would reflect it's output as the same, so would only the top half of the sine wave be presented, and would the AMPs reflect this also.

If this is so, would this be a way I could get hundreds of DC amps without using a ultra heavy duty diode on the output of the MOTs secondary coils.

I think a stream of DC pulces will be able to really give the offending cells a bit of a workout and perhapse recover them back to a resonable capacity, or at least recover the cell somewhat.

Now, the AC here is 50 cycles, so if I place a diode on the imput, I should get 25 pulces in and 25 pulces out.

Here is a schematic of a radiant charger.  Unfortunately I don't know where I found it?  It may not work for nicad?  However, in my readings, some posts indicate success with nicad batteries.  Research it before trying on your batteries.  Otherwise find a heavy duty diode. 

Thankyou tishatang

@electricme
My quick answer is that it will not work.  An inductor will kick back what you put in just like a capacitor.  Even though you pulse the primary, as soon as the pulse stops, the inductor will push back the current you put in.  The secondary will see a distorted AC input signal.  The secondary will tend to smooth it out even more.  The end result will be AC.  You will need the heavy duty diode on the output.

There may be another way to condition the weak cells by radiant conditioning using a Bedini type charger?  Use the search function on this forum and search conditioning batteries, or reconditioning batteries or something like that.  Somewhere I have an article or link.  I will look for it.

I am currently modifying a small plug pack iron transformer, I will produce the results, with my findings, DMM and scope screens.
1679 = Here is my small AC 240v in and AC out, the PCB with bridge and smoothing cap has to be removed.
 

I am open to what ever results are seen.

Thankyou

Serendipity plays a part in life, especially in science.  You may have just discovered a way to prove excess heat in to an inductor using timed pulses.  See the the Rosemary Aimslee thread.  That thread is a barrel of snakes and a big pissing contest if it is OU or not.  Partly because they are using small resistor inductors.  The small currents and heat are subject to measurement errors.  You, on the other hand may have found an experiment you can grab onto.  Or not, if it's too hot!  WE all need an efficient heater.  It's already starting to be a cold winter.  You might want to tell Rosemary what you did and let her see if it is related to her patent?

@MW383 and All re dowsing

Its like the realtors say, location, location, location.  For the EB to work, we must know to best places to put the rods.  In the old days, people were more in tune with the earth.  I will say if you have a skeptic mind, dowsing won't work.  You have to believe it will work and ask for what you are looking and the earth currents will respond.  A lot depends on your emotional state and need.  Here is my experience with my only attempt at dowsing:

In 1969, my small town experienced a major flood.  About 14 people died in mudslides and about 60 homes destroyed and maybe 200 badly damaged including mine.  It took about one year afterward for me to get the energy to rebuild my house.  I needed to find the water meter.  After one year the ground had dried rock hard with the flood debris about two feet deep.  I dug about three holes where I though the meter was.  I could not find the meter.
I have a bad back and digging is very difficult for me.  I thought I would try to dowse for it.  I got two welding rods, bent them in an L, and walked in a straight line and got a feeble reading.  Not being sure it was a reading, I came in from a slightly different direction and got another small reading at the same spot.   I said OK, I will dig another hole.  Lo and behold, I hit the meter head on.  Even though I had never dowsed before, had no lessons, I did have a great emotional need to find that meter.  It has been said that earth currents are semi conscious.  They will respond to your needs.  If the dowser wants water, his mentally asks for it.  If he wants gold, he states his need and the currents respond.  I wanted my meter and I found it.  Ask for the best place to put the rods.

Here is the best doc on dowsing as an attachment:

@Bill

In the beginning, I am sure dowsing ability played a major role with Stubblefield.  However, I've come to the conclusion, that later on, he was able to condition the ground.  At that point he could have put the rods anywhere within the conditioned field and drawn energy.

I hope my intuition is correct.  As I develop theory of his EB, I will reveal how I think he did this.  My idea started on the other thread and I will continued my thoughts there.  That way a year or two from now, a new person may find the thread and everything will be in the same place.  I may be wrong, but it could be a piece of the puzzle.  If I am right, it would be nice if we did not have to worry about where to put the rods.  We just put them in the ground and condition the spot where they are.

Chris:

You might be correct.  All we have is what we can read and we have to decide what is correct and what may not be.  As I have said before, if it was something specific to Stubblefield's farm area, or conditioning he did to the ground, how did he make his system work when he took it on the road for demonstrations in Philly, NY and Washington DC?  One of these, he did in the Potomac river itself from a boat.  His system still worked.  That is what I can't figure out.
