The prize this week is a solar flashlight, if you want to use this as a flashlight you better charge it during the day and not keep it hidden in a drawer. 🙂 I am thinking that the housing could make for a very small surface mount project. Not sure if the solar cell would have enough power to energize a very low current circuit but I would think it
