| Feb 25, 2018 at 18:50 | comment | added | piojo | Thanks! I just added details (like the formula and the initial acceptable step sizes) to the question. I'm keeping the formula, since I need something a bit different than linear brightness response--the goal is to not wake a person (me) up until near the end of the time interval--the brightness is supposed to sneak up on you, but not so much that your body hasn't started preparing to wake up. I don't know the theory of this, so I've been playing it by ear. I found a model of sunrise ramped up too quickly, so I wrote and tuned a formula. | |
