Hi all,
I thought that this could be of interest to many on the Sundial list:

Kenneth,
Yes Julien Coyne has done a very nice job ... with limitations due to
solar declination. You can read about that and a number of other
digital sundial designs as well as my new digital design for 3D
printing. It will be in the NASS March edition of /The Compendium/. If

hi,
Just came across this website that does 3D printing to create a digital sundial.

Yes, an interesting approach to designing and building a digital sundial
(see also www.sundials.org). I've downloaded the 3D files from mojoptix
and have just finished building a 3D printer to create one. However, in
taking a long look at his 3D model, the sunlight can only penetrate

I too have been exploring 3D printing for a digital sundial (see
http://www.sundials.org/index.php/dial-links/videos/digital-sundials ).
Because I do a lot of programming, openSCAD is wonderful, allowing
precise control of shapes and allowing structures that until now were
only
Very cool. Has anyone had a chance to try the free 3D software OpenScad?
By the way, I am skeptical that the sundial can handle declinations near
the solstices.

I've seen :) That's cool. The only disadvantage is relatively low
resolution; 20 minutes.
Take care, Marek

Hi all
I think it can also work with a square section, so it should be easy to
laser-cut.
I also think the holes on the other side of every number may become a
window, with inside frames, to allow a projection with any

This may force me back to the drawing board since I hold US Patent

Great idea. A beautiful form for this type of dial. Thanks for passing

This seems a form that was referred to as punctiform by Gianni Ferrari.

Dear Sundialists,
many thanks for your interest and the question if our digital sundials
work on the southern hemisphere.
Our current version of sundials is built for the northern hemisphere,
but there is in pricipal no problem in changing the order of the numbers
