A 500 lb cube declining dial, 11 pages about 600k, all details start to finish. A large analemmatic garden dial.
An inclining decliner. A vertical decliner neighborhood project using empirical methods, shows Italian hour
lines, 5 pages, under 200k.  A circular paver equatorial, a clay pipe liner armillary. The open book dial or dual
gnomonless dial back to back.  An almost 45 degree declining four faced cube dial.  The details are complete,

SOFTWARE
l
ots of it, free
This website and its free books, booklets, programs, case studies, take a lot of effort to design, build, buy the CD, or and
maintain. If you like what you see, please consider acquiring Illustrating Time's Shadow.  For example, the DeltaCAD macro for
the astrolabe was a first in astrolabe programming in that you get the source code and explanatory notes, and it took hundreds
of hours, and it is free to you. Pieces have been published before, but this web site was the first to show in a
very few pages the
complete design of the astrolabe.  The online download and CD purchases provide the incentive for further development. And
help when I teach classes on sundials at the local university.

WHAT KIND OF SUNDIAL TO BUILD
Before you build a sundial, decide what kind is best. Latitudes between the
equator and about 15 degrees N or S would benefit from an equatorial (q) or
polar (p) dial more than from a horizontal (h) dial design. On the equator a
horizontal (h-dial) is a polar dial so use a p-dial design. At the poles, an h-dial
is an equatorial dial, so use a q-dial design ~
run the DeltaCAD h-dial at low
and high latitudes for fun, they approach the polar dial and q-dial
.

contents here, and with it (printed, CD, or online download) you may download the
Supplemental Shadows book itself (120 pages, contents here) as well as
Programming Shadows book itself  (290 pages, contents here)
Hands on, empirical, geometric, trigonometric, CAD,  spreadsheet, and tabular dial design for small dials,  and
garden dials using common material, as well as clay, glass, and copper, with emphasis on calendar line
techniques, and Babylonian/Italian lines, while providing details on the use of DeltaCAD, FreeCAD, NanoCAD,
and web Java Script programming including the animation of many sheets as parameters vary.  Case studies
abound with associated problems solved, and cover the infamous inclined decliner, as well as all the other
kinds of outdoor dials.  The printed book comes with a CD of booklets, spreadsheets, VRML files, templates,
etc. The CD has all books, booklets and programs along with source code.  
You can get the CD, or an online download (Acrobat 7 or later) here.
