THIRD EDITION

         There are some updates, see below  click here for updates themselves , and general update notes also  

         
11/18/06          SUNRISE AND SUNSET FORMULA:
                                      hsr = arccos( tan(lat) * tan(decl)  )
                                      The formula was correct, the note said from noon but it is as the formula says, hour angle.

         
11/18/06         THE 2 SINE WAVE EOT FORMULA IS BETTER SHOWN AS   
                                      eot =  7.36*Sin(2*3.1416*(doy-4.21)/365) + 9.92*Sin(4*3.1416*(doy+9.9)/365)   

         
11/1/06            There are some notes on altitude and azimuth dials not being latitude portable. The following note is more accurate.  "Hour angle dials
                                      use the hour angle around the style and can easily be latitude corrected by tilting. Italian and Babylonian hours are not corrected when
                                      a dial is tilted because they depend on the Earth's curvature [which causes sunset/rise] at a specific latitude. Azimuth and altitude
                                      dials may be ported across latitudes but rigid polar alignment must be retained."

        
11/26/06          Pages 168, 170 of chapter 10 and page 258 of appendix 8 have the formula for hour lines for inclined decliners, the angle produced is
                                      from the vertical, the notes say noon. Corrected in the downloadable files for book 2, the
download page is here and needs a
                                      userid/password to actually download.

         
4/11/07             Chapter 8, Figure 8.5 in Illustrating Shadows, winter and summer solstice names were reversed.

         
12/31/07           Page 175 has spurious text "INCLINES" and "RECLINES" due to a Microsoft Word bug.

         
3/16/08            Pages 115, 156 typo in hh.h and mm for DL, also appendix pages 250-270 now DL hh.hh are 2 significant digits.                      

        
If the print date of your book is later than the above dates, then your book has the changes incorporated.

ILLUSTRATING MORE SHADOWS updates

       12/31/07            Page 89 has the words "winter solstice" for both the lower and upper curves, as this is a vertical dial, the lower curve should say
                                        "summer solstice".
      2/3/08                 Page 217 has a C program with a line:-  printf ("Uncorrected hour line angles \n" ) ;
                                        the line should read:-                               printf ("Corrected hour line angles \n" ) ;

        If the print date of your book is later than the above dates, then your book has the changes incorporated.

DELTACAD MACROS - click here

        the h-dial programs could draw an extreme hour line in the wrong direction in the boundary box for some longitude differences. Fixed, and also added
       N/S hemispheres, and extra precision for the tabulated angles

TURBOCAD vbs macros here - the h and the v-dec dials in VBS and notes on programming it also.
OPTIONAL SPREADSHEETS OR TABLES

general spreadsheet    You enter longitue, latitude, and date and it gives you azimuths and altitudes,  hour angles, and works for
                                horizontal, vertical, and declining dials. Also shows  pie chart techniques to display hour line angles. Also has
                                the great decliner sheet  14.9 in chapter 14, and includes the wall-declination finder spreadsheet above as
                                well as the unknown-store-bought-dial latitude finder mentioned above.  
Astronomical EOT formulae as well
                                as
lunar phase formulae added as worksheets, with mean as well as true dates.  Astrolabe stuff, and more.
                                Includes a sheet for declining incliners.  Uses
this additional spreadsheet. Better wall declination and astro
                                compass work also.   NOTE: versions have been written for Documents To Go and the Palm Pilot.

                 
NOTE:  illustrating-shadows.xls and illustrating-shadows-eot.xls replace reference-spreadsheets.xls and a-sundial-aid.xls  

the files above are in pure Excel form and are on this other web site, and if you don't have Excel then there is a free and low cost compatible verison called Software602, and if you need
a free CAD 2d drawing program, consider this one on
the main web page here. The main web page for this book has links to free up to date viewers for Excel, Word, PowerPoint, and
Acrobat as well as other free stuff. Check free
Micro Shadows, and if you like that get Simple Shadows which gives you a flavor of Illustrating Shadows, it is free also.   In fact, give both
Micro Shadows as well as Simple Shadows to a friend...

ILLUSTRATING MORE SHADOWS. Whereas Illustrating Shadows focuses on theory and small dials and detailed dial construction, this book focuses on larger outdoor garden sundials using commonly
available building materials from any building supply store, glass, and clay. While the book reviews all the normal dials for completeness, that review is an overview rather than the in depth treatment of the first
book. The exception being the inclined decliner and the declining dials, and extensive work on calendar lines. There are chapters dedicated to both cube decliners for the garden (16 by 16 inches) and to
inclined decliners, with all the design methods, and construction notes from start to finish. Inclined decliners will be a piece of cake with this book, and fun to do, and the spreadsheet for the book was completely
rewritten to facilitate the process. There is a lot of work on DeltaCAD and even animated dial plates in DeltaCAD so changes in parameters can be visualised. Extracts from some chapters are in the case study page
here, and they are extracts, and may have typos, fixed in the book of course. The actual chapters are much more extensive. A few pages from this book are here...  And as soon as I get the PayPal notification, I will
email you a userid and password so you can download them now if you like,
