I used a Raspberry Pi to solve the problem that the trash can in front of the building where I lived was often overflowing when I tried to take out the trash: I connected a 20x4 character LCD to the Pi and put it next to the bathroom mirror. The display displays some useful info: - Estimated garbage can levels (interpolated based on the trash calendar) - weather forecast - cryptocurrency prices So when I notice that the trash can level is low I can take out the trash without troubles. (These days I use my Pis for more simple things like RetroPie+Kodi and PiHole)
