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

7:00 PM Yesterday
I wrapped an additional layer of cotton around the outside of my 2nd coil build (on top of bare copper wire).
  soaked the coil in water for 2 minutes,
  wrapped plastic around the coil to possibly slow down the drying out effect.

readings over past 24 hours:
.927V 7:05PM  (didn't take A readings) 
.935V 7:49PM  (didn't take A readings) 
.775V 10:15PM  9mA
.658V 6:44AM   6mA
.614V 3:29PM   4mA
.586V 7:23PM   3mA

I unwrapped the plastic, checked the outside wrap of cotton and it is still wet, wrapped the plastic back on.

PS: I shorted my copper to copper and steel to steel like Ted did and my amps went down but my voltage went straight up from .586V to over .720V in less than 1 minute.  The voltage is settling in around .735 after 3 minutes.

Weird is the word

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

Hi Ted.  I'm so jealous.  I've spent the evening winding about 1.5 inches - a quarter of the required. My fingers are 'black' - my eyes exhausted - and I've lost the bobbin holder twice.  The one time it flew off and cracked -  AAGH.  Fortunately I had another spare.  But WHY won't it stick?  I'm using Pratley high strengh quickset.  And they show pictures of it holding up whole bulldozers. It's meant to dry in 15 minutes.  And this is now HOURS ago.  Added to which - that stripping of the copper IS FOR THE BIRDS.  I couldn't get any kind of systematic winding with the nichrome.  Anyway I'll press on - pressing on.  It's now 2 in the morning and I'm going to see if I can hold the one prately's holder on with some wire.  Maybe it'll hold better.

Regards,
Rosemary

Maybe found the problem.  It's plugged the glue at one side of the the pipe to hold in the filings.  And I think it's too thick to expect a quick set.  I'll leave it for the morning to get thoroughly dry.

   Am beginning to appreciate the skills you guys have.  Definitely an art form here.  Well done Ted.  And Don - I am now blown away at what you've managed and all so quick.

Continuing along with the weird theme... I shorted all the separate windings together, both top and bottom... and the current increased. You can see when it's in the vertical position the current is around 119ma. When I tipped it over to show the bottom shorts, it gave me a few more ma's.
I don't know whether to consider this a battery or a self filling capacitor (is there a difference?). I doesn't act like a coil though. I'll bet you could get the same results with two sheets of metal coiled up like a capacitor with some cotton in between. That's essentially what I have here. I may try that next...

Manually heating up of the coil makes a difference also.
I used a hair dryer to warm up my coil a little and the volts increase from .400V to over .500V in 30 seconds.
