Self-Runner NS Coil Pulse Motor Live Video Stream. It's been going for months!

Hi all

I couldn't get access to our lab as there was a mix up with keys.  Hopefully tomorrow.  Meanwhile I improvised on the base for the bobbin and constructed my own with plastic putty.  Am still stripping wire but hope to have a couple of windings done before I crash.

Here's the record.

sorry guys.  Usual errors with the downloads and I can't seem to delete the duplications.  I'll try this again.

Finished it, it took forever to wind. I used about 200 feet of both copper and steel 20awg wire.
The dry voltage across the coil was .69 volts with the copper positive. Current was a minuscule 40 ua.
I sprayed it with some tap water, which got about a third of the layers wet, and the voltage went up to .75 volts. The current jumped up to 19 ma.
The current and voltage were unaffected by inserting an iron core into the coil. The iron did polarized and would deflect a compass at either end. However, I couldn't get any response from either the compass or a piece of steel wire when I shorted the coil.
I'm not used to these low power devices. If I fire one of my motor coils up on the bench, I get all kinds of metal crap flying around.
Anyway, I decided to soak it in salt water and see how it worked after that. It currently reads .82 volts at a respectable 85ma soaking wet. I'll dry it out and see if those values hold up.

Cheers,

Ted

Very nice build!  Hey, 85 mA's is a great power output in my opinion.  I think it would have been cool to bury it in the ground before adding the salt but, too late for that.  All of my coils went up in power and volts when in the ground, for what that is worth.

Of course, to replicate what Laser is doing I believe you are right on the money here.

Again, very nice job.

Thanks Bill. These things are weird. When I shorted the two ends of the copper together and short the two steel ends, the current between the two went up to 106ma. Instantaneous current is over 200ma, then it drops down to a steady 106.
I couldn't detect any solenoidal pull either. A steel rod partially out of the center exhibits no detectable movement when the leads are shorted, even when balanced on a very soft spring. This indicates little or no net current flow in one direction, which would be keeping with two generators (the two wires) pushing current in opposite directions. But then how do we get a polarity on the steel? A slight imbalance maybe?
I'm not really sure anymore how Laser's motor is running either. Perhaps there's some inductance from the spinning magnets that dictates polarity? I'll have to think about it.

Cheers,

Ted
