From Waugh to Weir: Easy Analemmatics

Michael Hickman introduces a non-mathematical method for designing analemmatic sundials using Weir's Azimuth Diagram. He explains how this navigational tool can be adapted to plot hour points and declination scales for dial design without complex trigonometry, making the process accessible to a broader audience.

Shepherds and Spreadsheets

This article explores using spreadsheet programs to design and create shepherds' dials, simplifying the complex calculations and plotting involved. It details the process of determining the sun's altitude using a mathematical formula and setting up a spreadsheet to generate the necessary data for plotting hour lines on a cylindrical dial, facilitating DIY dial construction.
