I once bought one of those alarms that brighten along with the pattern of natural sunlight in the morning (and dim in the evening), as I don’t get much natural light in my bedroom. The time display on it was so unbelievably bright at its lowest setting that my sleep was worse until I piled stuff up in front of it. I don’t even bother with it anymore.

A related problem: I do get some natural light, but also a lot of night-time light from the apartment complex parking-lot lamps.

I've been thinking of a time-controlled motor on my window blinds.

Literally same here. Could've written your comment word for word.

That was going to be my DIY project, time to finally do it, I guess.

Renting, I'd want something I can temporarily attach to arbitrary pre-existing blinds. On reflection, there are several types one might encounter but I'm particularly thinking of the "twist stick to adjust horizontal slats" style. (As opposed to "loop of chain controls angle", or "fully unroll from top".)

I think there was a Show HN some months back where somebody 3D printed a mount so that the twist-stick could be slotted in at a slight angle.
