Sundials in Utrecht

2011-10-20 Thread Daniel Baker
Hello 


I am spending some time in Utrecht at the moment. I wonder if anyone knows 
where I might find a list of sundials that I can visit in the area? 

I would appreciate any advice on the matter.


Best regards

Daniel

Hi all
 
about ‘finding North’ I have news of 10 years ago or more.
 
It is just a case but in these days I finished to update Nord.exe, a software 
to get solar compass I wrote in the last century.
It needed to be renovated including the name, since it also printed solar 
compass for the South Emisphere.
 
The software was made with Visual Basic, it was possible to download it from 
internet and it was bilingual (italian and english).
 
While I was growing old, computers and OS became old too, even faster than me, 
so in the new release I had to solve some troubles: Microsoft gave up Visual 
Basic some years ago, the VB software doesn't run on Mac, 64 bit PC e the new 
OS (Vista, 7) may have problems with this software, not to mention new 
platforms and so on. So I decided to write a cloud version: the software run on 
the server, you can use it with a web page, it is indipendent of your computer 
or OS and every update is immediately available. Obviously an internet 
connection is needed but if you read me that isn't a problem.
 
You can find the software in a page of Sundial Atlas, this is the link to reach 
directly it:
www.sundialatlas.eu/atlas.php?gnomolab=2
 
Insert the coordinates (orange asterisk next to latitude), choose UTC, set some 
layout options, push the 'drawing' button, wait for few seconds and you will 
get a pdf document with the solar compass, then you can print it or save it.
 

In Sundial Atlas you can also reach the solar compass page from the card of a 
sundial (the link is in the right column); in this case the compass is already 
setted with the coordinates of the sundial.
 

It is possible to customize the solar compass with a text and setting layout 
options, I tested the software with many different schemes, anyway if you find 
bugs or you have suggestions or you need any info, please contact me.
 

from the clouds, ciao, Fabio
