Re: [TCML] Pairing two separate coils of different powers

[mddeming@xxxxxxx]

Hi Norman, Dex, All,

The problem with making accurate size estimates from these pictures is that there are no viable visual references. All we see are two sets of dancing sparks in almost total darkness, one set of sparks being much brighter and appearing significantly larger than the other. IF we knew that the camera was equidistant from both coils, and IF we knew that the camera was sufficiently far back from both coils to not be introducing optical distortion, and IF we knew which sparks were essentially coplanar, then and only then could we judge the relative sizes with some reasonable accuracy. We would still have the problem that bright objects always appear larger than dim objects, and our eyes tend to judge objects radiating near either end of the spectrum to be smaller than those nearer the center.  (yellows look bigger than reds, blues look bigger than violets etc.), but those are smaller considerations.

The larger of the two was getting 30" hits direct to ground, the smaller coil 
as getting 14.5" direct to ground. thats pretty much half, plus neither one has 
eally been tuned perfect. a far as it looks in the video, I don't know mayb it 
s just being over-shadowed by the larger coil.

 noticed another thing.
treamers of the 450W coil are more than
 times longer than stremers of the 180W coil.
he difference according SQRT(P) rules
hould suggest less than 2x spark lenght in
he favour of your friend's coil.
omments?
Dex
