Change History

Update (12-07-24):  If you live in the southern hemisphere, make sure to use the southern hemisphere analemma design in addition to the southern hemisphere dial plate. 

Update (01-02-25):  As requested, please follow the new set of detailed setup instructions provided in the file section titled: How_to_Setup_your_Original_Heliochronometer_Sundial-Detailed-Instructions-v1

Curved vs. Flat Analemma Plates:

This model includes a flat plate analemma & fixed nodus.  You may gain a bit more performance & reading accuracy from your heliochronometer if you adopt a curved plate design with a tilt adjustable nodus.  If you prefer upgrading, check out my other Printables at:
