I always try to do something physical like riding my bike or at least going for a walk. I try to do things like this regularly and I usually get creative blocks when I skip on these things for a few days.

You can find great ideas by looking at other mediums like TV or magazines. You'll see good designs that might inspire a new project. You might also see a good design and start thinking "How did they do that?".

All of these things can solve both creative blocks and boredom blocks.
