Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[Freezer]

Here's what I drew up so far.  Don't come down to hard on me, as this is just a start, and lots of things can change.  I'm not stating this is the correct way, I'm just looking for feed back. I want to get it right before I even start to build.

@ Joe:

Sorry man.  I saw the patent diagram when you posted it but, without my machine shop equipment, I would not know how to go about building one. I think the idea of it being "self powered" is better for us.  Maybe we could replicate a reasonable facsimile from some tubing, springs, coil, etc.?  Maybe the tolerances don't have to be all that close for it to work. Maybe we can make Hans's design work from the power of the primary somehow?  That would be beyond my present understanding.  I don't really care which way we go as long as it works and can be readily built and replicated.  And, also for me right now, it has to be cheap or I will need to wait to proceed.  But, that is my problem so don't let it influence the rest of you.

I am still soaking my coil in hot water.  It is getting better.  Now, there is only a short from the iron wire to the core.  All other connections are isolated once again.  Thanks Bruce for your idea.  It appears to be working.

@Joe,

You never PM me your mail so I reposted my lead acid charger circuit here:

http://www.overunity.com/index.php/topic,4057.0/topicseen.html

This charger will work on almost any input voltage (up to the max. transistor limit).
Best input voltage to circuit for charging 12 Volt lead acid batteries is 9 Volt.

@ all

Whatever is easiest i guess.. 

@ jenna i know there not touching, but if you tape a magnet on the table and tape a bolt an inch a way from it ,,, it residually magnetizes the bolt.. no touching but proximity. Thats what i meant about riding dirty .. sorry i hate rap music and ive been waiting for a place to interject that phrase.. its kinda funny. o and wires 5 and 6 are the terminals on either side of the inturrupter,when shorted

@Freezer Great model except for one thing... Your primary is wrapped on the outside of your secondary... IT goes . BOLT INsulation Primary Insulation secondary.. It threw me at first two... Every tesla coil ive seen or impulse transformer of the sorts has had a small turn primary outside the secondary coil.. not within it circumference...  So that is something special about this little earth battery as well.

@Bill
      I agree if it works to start with cool. I have just about finished my crude spark gap model..  Now all thats needed is a novel way to attach a small disc to a hobby motor and hold it in place.

Best luck to all, and in the words of bill .. remember "NOT " to use salt.

G'day all,

@ Bill,

I don't see any point in inserting a potentiometer. The frequency is generated by the physical structure of the device. When the magnet energises, the hacksaw blade is attracted and breaks contact. The hacksaw blade springs back, closes contact again and the cycle starts anew.

Now either the magnet pulls, or it doesn't. You cannot influence the cycle by changing the power supply. Any power source sufficient to attract the hacksaw blade with enough force to break contact will do.

@ Joe,

The commutator in the patent has been specifically designed to suppress the formation of sparks. (See below)  In my humble view this is not what is needed here, nor do I think that this was in Stubblefield's mind. Let us not forget that all the early radio transmitter circuits relied on the spark as RF generator.
