Hello, I've always been fascinated by Sun dials and have just found this group surfing around after making my first working Sundial using Shadowspro. It's found here: http://leewm.freeshell.org/origami.
All the sundials that I've made before didn't work in my location as I didn't understand the concepts and they were designed for the more northern regions. In the ring sundial found in http://www.pocketsundial.com/, how does one calculate the the location of the hole in the centre portion that acts as the gnomon? I'm sure the radius of the circle has something to do with it. I'm sorry if I used the wrong terms as I'm just picking up the vocabulary. Thx very much :) weemeng -
