    3D Printed Wireless Lantern

    Is there anything in your circuit to turn off the LED if the battery drops below 3v?

    Easiest fix would be a protected 18650 cell, if you have room for it. I love your design, though. I've been wanting to build something similar, but shaped like a Star Wars holocron, for years.
