[Madaeon] pointed us toward this entry for the Instructables Epilog challenge. While this may not be extremely complex, or have as many wires as our typical post, it is a fantastic example of thinking outside the box. How many lemon batteries have we seen? A lot. This one stands out as being more elegantly displayed and functional at the same time. In its final form, you sprinkle lemon juice on it’s petals and it lights up. If you ever find yourself in the position of teaching someone about electronics, remember this project. Sometimes aesthetics can make a dull simple project take on a life of its own.
cool. a way to extract some beauty from acid rain?
