TK, is your observatory all set up for this evening's moon-shadow?

                          Solar Eclipse of 2012 May 21 Sun in Partial Eclipse at this Location Delta T:  66.8s SOMEWHERE IN, TEXAS Location:  W xx'00.0", Nxxxx'48.0",     0m (Longitude referred to Greenwich meridian) Sun's           Position     Vertex UT1         Altitude   Azimuth      Angle       Angle d  h  m   s         Â°          °           Â°           Â° Eclipse Begins    21 00:35:55.7       8.7      288.4       275.5       213.7 Sunset            21 01:23           ----      293.9       ----- Duration:   0h 46m 49.3s Magnitude:   0.911 Obscuration:  85.2% 

This means that it's too low on the horizon for me to see it from where I am, but I should be able to detect the sky darkening.
I don't have a manual mount or I'd grab the M90 and go to the park down the road, it might have a view that low. But.... no manual mount and the CGEM is just too heavy for casual moving about like that.

TK:

I watched the turnip stew clip.  The one thing that intrigues me again is seeing that when you make the gate signal go high it gets clipped and when you look at the current waveform when the gate signal is high you can see it undergoes an exponential decay.  I am assuming that there is a chance that it is related to the zener in Q2 starting to conduct, as was discussed a few days ago.

It's an interesting puzzle for those that might be curious to explain it.  If I had my own setup and a bench full of equipment I would try to figure it out.

It's all moot though because the real issue goes back to the claim.  You can see how even for a simple circuit like this that understanding the switching dynamics are not trivial.

So all paths lead back to Rosemary's front door:

Rosemary, when do you plan on doing the dim bulb testing?

Rosemary, will you include the extra measurements like I requested assuming that you do indeed perform the dim bulb testing?

A little interlude for some bemusement....

On another thread Rosemary said this:

INDEED it's good news.  And THANK YOU CHESS.  And WOW.  I think that elephant in his armchair has lost his trumpet.  How good is THAT?

As ever Chessnyt - Your work here is BRILLIANT.

Kindest as ever,
Rosie

So, you look at someone like Picowatt.  A man who clearly knows his stuff and most likely has been an electronic design engineer for 40+ years.  He clearly has great working knowledge and expertise with MOSFETs.

I am sure Rosemary has called him "stupid" many times over the course of the discussion.

Then you look at someone like Chessnyt.  For the most part all that Chess is doing is copying and pasting stuff about Rossi that anybody could find in 30 seconds.  That demonstrated  superb mastery of the right mouse click.

And for this work Rosemary has called him "BRILLIANT."

It's the Bizarro Universe in action!!!  lol

TK,

Bummer that you'll be unable to view the transit from the yurt. Here in PDX, the overcast and drizzly skies will likely make for a less than spectacular event also (pissed!). Thanks again, as always, for your educational video... perpetually looking forward to the next.
