My pal and seasoned technologist (sounds delicious doesn't it?), Nate Hunsaker sent me a link to these OOOMS designed birdhouses that provide more than just a roof for their residents:
During the day sunlight feeds the solar panel , charging a small battery inside. At twilight the transparent stick will light up and cast a tiny light on your garden.
This light attracts an easy nighttime snack for the bird; all she has to do is stick her beak out of the hole and wait for the buzz.
