Heliodons are devices that primarily simulate the direction of sunlight for testing physical building models. Some of the heliodons that I have developed can simulate sunlight direction for all combinations of day/ time/ latitude.

I present below more about heliodons:

1. My reserch into heliodons and sundials

2. Dufton and Beckett heliodon

3. Some web sites of heliodons

4. The solarscope, and Solux

5. Sunlight heliodons

6. Artlight heliodons

7. Image/Data Acquisition and Processing System

8. Site surveying tools for insolation availability

9. Miscellaneous Related Tools

10. Lightless heliodons

11. An International Heliodon Forum
