--- Begin Message ---DEAR SUNDIAL FRIENDS, I want to share with you my finished work on the previously announced NODUS PYRAMIDAL SUNDIAL COMPASS. I think that for latitudes close to the equator, a final extension deserves only the 4-sided variant (inspired by the 3-sided Liebscher's trileg). The addition is a square drawing on the side face of the pyramid, which must be tilted to horizontal position. The most suitable inclination is 60 degrees. On my page, a visual illustration (for the equator) and two PDF files are included for Singapore (1.3521 N) and Adelaide (34.92 S - Thanks for Peter Mayer's test!): https://www.math.bas.bg/complan/valhrist/mystuff.htm#Pyr Please, reload the page!
