Programs for HP-41

Sunrise/Sunset calculator

Postby ndiniz » Mon Oct 19, 2009 5:26 pm

I now have the HP-41CX (i41CX+ for the iTouch from iPod), and now I want to figure out if it's possible to create a sunrise/sunset application that would allow the user to find out the time of Sunrise & Sunset from their location using Latitude & Longitude as the entry for their location. I also want to be able to let the user have the calculator sound an alarm at Sunrise, Sunset, or both. Just thought I'd ask. It'd be neat though. I used to have a Casio watch that'd do that (but without the Sunrise/set alarm feature I want to use). Can anyone help me with this?

This function is built into all GPS, so it should be able to calculate.
