Hi: This is a little off topic, but bears a strong relation to sundials.
After watching a TED talk on taging of tuna with sensors that determined the Lat and Lon of the fish based on the length of a day and the time of sunrise and sunset I found this method is called Light Based Geolocation. I'd like to learn more about what data the tags store and how smart they are. For example is there a micro controller in the tag that make computations or is it just a data logger? -- Have Fun, Brooke Clarke http://www.PRC68.com --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
