Backlight - scheduled change? (or - Profile scheduled change?)

[deim]

Hi guys!

I'm trying to find out how I could schedule change of backlight level?

Well, I'm using my iPaq hx2750 to read some books (in the evening, actually, in the bed :D ) So, I'm changing backlight to the minimum. But in the morning I have to change it back to ~50% level.
Is there any way to automate it?

Ok, first part of my question actually has very simple answer - I can create/edit profiles and change backlight brightness level there.

But how can I schedule profile changes?! Found bunch of programs like Profile Switcher, but all of them are only for smartphones! How about regular pda?!
