| JustBASIC (a free BASIC system, with an extended version for a modest fee) their main web page is here (www.justbasic.com) FREE ~ The benefit of these programs is that they run on a free system, so if you don't have TurboCAD, DeltaCAD, or Excel, you can still have some fun with programming. These are provided in BASIC as well as in current virus checked executables if you do not wish to download the free BASIC compiler which is a true IDE. an almanac EOT, declination, sunrise and set, hourly altitude, azimuth, h-dial and v-dial data a horizontal dial A very simple BASIC program using the free JustBASIC system. horiz, vert w/wo decl Same as the h-dial but adds vertical dial with and without a wall declination declination curves This shows calendar points for a given SH (style height) and a given style linear length. These data may then be used on the SD extended for a horizontal dial, or on a vertical or vertical decliner when of course the summer and winter solstice data is reversed. Updated with more options also added to the statement of assumptions solar declinations used Revised Feb 10, 2008 with clearer messages. polar/meridian dials This displays hour line distances from the sub style in 60, 30, or 15 minute increments, for longitude corrected polar dials as well as for true meridian (true east or west) dials. Also displayed is the calendar data for 1, 2, and 3 months from the equinox. And Italian line data. meridian but inclining This does the true east and true west but inclining dial and prints all sorts of good figures to draft the plate. zip of the above JustBASIC files above zipped [file size is 10k - small] zip above plus executables This also includes the BASIC files in executable form along with the run time libraries, so you can just click on the filename.exe and run asis without the BASIC compiler itself being on your system. There are virus checked with current professional software prior to upload. Please read the readme file if you want to run the .exe versions [file size 1.5mb] __________________________________________________________ Again, JustBASIC is a free program, and they have for a nominal charge an upgraded version, and well worth downloading. The JustBASIC web site is here. The above BASIC programs somewhat parallel the DeltaCAD macros here, except these BASIC programs produce tables of data and do not print graphical depictions. |

| Illustrating Time's Shadow ISBN 0-9765286-8-1 plus 0-9765286-9-X Lib Cong 2005900674 plus 2006930654 Merges Illustrating Shadows and Illustrating More Shadows, deletes duplicated material, and techniques that are complex and replaced by easier methods, adds new material. Hands on, empirical, geometric, trigonometric, CAD, and spreadsheet dial design for small dials plus garden dials using common masonry supplies, clay, and glass, with emphasis on many calendar line techniques, and inclined decliners, while providing details on the use of DeltaCAD 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/WRL files, templates, etc with the printed book. The CD has all books and booklets and programs along with source code. You can get the printed book and CD, just the CD, or an online download here. |
