The LED flower is about the closest I have been to being and artist. One day I just had the motivation to build something artistic. I took a wire hanger and bent it into a shape of a self-standing flower. Cut up a milk jug to make the leaves and petals and glued a LED to each piece of plastic. I built a circuit on protoboard and installed it as the center of the flower. The circuit I designed uses a photodiode to turn a transistor on or off so that the LEDs are only on when the room is dark. The whole flower runs off two AAs but I soon hope to add a wall transformer to it.

You should add a solar panel switch to rechargeables! Nice one!
