Hi Ray,
I just came home from a longer holiday and found the discussion on rhe
Hollander Dial.
My software "SONNE" calculates Hollander Dials too. I calculates
horizontal and vertical Hollander Dials (also declining vertical). In
some cases the angle of the cone apex becomes very important for the
result. So it is important to see the results for different cone apexes.
I have such a vertical declining sundial and it works perfect. (I hope
the attachment is enclosed).
You can download the free software from my homepage http://www.helson.at
But I must tell you that BitDefender supposes my homepage is malware.
Therefore I tested my homepage with https://www.virustotal.com/. This
page tested my website on 63 antivirus programs and only BidDefender
says it is not clean, all others find it to be clean. Until now I could
not find the reason why BitDefender judges it as malware.
Bst wishes
Helmut Sonderegger

Hi Roger,
I did a search for "NASS Compendium 14-2 "Hollander Dial Software";
unfortunately the link to find a DeltaCAD marco was not available or I
missed it, or perhaps you have to be a member of the North American
Sundial Society to access it. Do you have a direct link to the Marco
for the Hollander Sun Dial?; I am also interested in making one.
Thank you,
Ray

Hi Dan,
As you consider conical gnomons, pay attention to the conical sundials of
Hendrik Hollander, the winner of the 2006 Sawyer Award. His conical
bi-gnomon sundials could tell clock time. Here is the note on his award.
"The 2006 Sawyer Dialing Prize has been awarded to Hendrik Hollander for his
innovative design of a mean-time planar sundial with oblique conical gnomon
and modified hour lines and day curves – resulting in a sundial adapted to
modern timekeeping while retaining the aesthetic appeal of the familiar dial
face."
Google his name and sundials to see what his conical sundials can do. A link
to this article published in the NASS Compendium 13-3 will come up. Also
check the digital bonus with NASS Compendium 14-2 "Hollander Dial Software".
Regards,
Roger Bailey

Subject: Metal cone
Hello all !
Any idea how much a metal cone would cost and where to buy it online? The
kind you can use as gnomon - Ebay has loads of punk spikes on offer, but
they are too small.
Thanks!
Dan Uza
