Hi John,
For one thing many folks may not have sent you the huge multimegabyte full
sized
pictures, since that takes a lot of bandwidth. What counts are a. the number
of
pixels total, the number of colors per pixel, the quality of the lens and ccd
matrix. For a low cost camera I bought an
Hello All:
Thanks to Robert Terwilliger, I'm finally able to show and tell you about a
beautiful new rare sundial that I made especially for debut at the NASS
Conference in Tucson.
During the past year I became very fascinated with Analemmatic Sundials. I
researched all the websites and
Hi John,
Way to go! I had seen the dial before, but not the new and improved gnomon,
which seems to work very well. Did you make the spiral-legged base piece
yourself? Congratulations on a fine effort and a top-rate new sundial!
About the camera thing...I have a Nikon Coolpix 600 and have
Hello John,
Like many others I went the digital camera route recently and have
really been convinced by what it gives me. The camera is a Casio QV-4000
giving 4 megapixels. I am not saying that it is the best. I went for
another make but the photostore man persuaded me that this was better

John et al,
So here's my two questions to Bill:
1. How much did your camera cost (If you don't mind telling)?
2. Does your camera have changeable lenses?
2. Since it is digital, can you make a close-up shot digitally without a
close up or telephoto lens?
3. How close

A word to the wise - OPTICAL zoom is the thing. Digital 'zoom' just
clips the middle from the image.
Exactly right. However, worse than that Tony (at least with my 3.3MPxl
Canon) when set to use Digital Zoom the wretched thing doesn't
Fellow Shadow Watchers,
I now have JPEG examples illustrating my query
but, due to incompatibility between my new Mac and my usual FTP software,
cannot publish these on the www until the problem is solved. I've sent
copies to thosed who responded directly.

Beautiful, John!! A real piece of functional art...
As I read your description, I also wondered why we haven't seen more small
analemmatic dials. It (now) seems like a perfectly natural idea! When you
mentioned having an attached, sliding gnomon, I had a vision of a

Dave,
If you put the gnomon on a sliding block, you could then easily make
an analemmatic dial with hour lines. Just attach elastic cords from
the base of the gnomon rod to each hour point. Or, you could use
weighted strings which run from the gnomon's base, sliding through
holes at each

it is. Anything that relies on screws, threads, or grooves is taking the
first step toward making it into a clock... you could motorize the screw
thread... The dial would presumably have to live in a private garden, but
it's too finely made to be left out in the public park anyway.

Now that is a clever original idea that I would like to see. Hats off to you

Hi Tony:
I understand in lime silos, where they convey the lime into the silo by
blowing it through a metal pipe to the top of the silo, that the 90 degree
elbows in the pipe would rapidly erode and fail. Then someone discovered
that if they intentionally built a small pocket into the outer
