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

Here is what I said earlier in the thread.

I did originally wet it in salt water, but since then I have not added any water at all.  It's been 75 days now running dry, though I am sure that air humidity is maintaining a low level of moisture in the coil.

Like I said, try plastic-insulated wire and let's see what happens, what voltage are you gonna measure then.

Thanks, I did read that. I'm just wondering how you've determined that it is dry, as multiple windings of cotton covered wire would seem to have the ability to trap the moisture. Especially when encased by a secondary of enamel coated secondary coil.

Hi Happy,

Maybe I can help you out here.  The lasersaber variation of the NS coil has no secondary winding.  The entire build is with iron and copper.

But I think Laser has gone to some trouble now to assure us all that there's probably some moisture in the coil notwithstanding only one dip in a saline solution some 70 or so days ago.  The surface is hard dried - and the iron is rusted.  But the rusting seems to have 'peaked' or halted - presumably therefore confined to the surface of the wire. 

Hope that helps and hopefully I've got it right.  Else please speak up.

Kindest regards,
Rosie

How can an incompetent person hope to have helped? That's impossible. Please try plastic-covered wire (every RadioShack carries such) instead of cotton-covered and then report back if you measured any voltage. That's the only guarrantee the two metals are insulated.
