The competition may be over, but this is still a project I would like to complete sometime. Over the summer I was donating Chrome books and kindles to little free libraries in my area.
I realize that might not be the standard fare of little free libraries, but the community response was welcoming. The Bangor Makerspace periodically receives massive donations of old tech that we have no way to deal with, outside of trying to do community projects like this. We also have a rather large collection of STEM book favorites. I recently learned that little free libraries can be indoors, which is suitable for our lack of an outdoor location to place a little free library.
