Moon Lamp

thingiverse

This version features an opening on top with a screw-on cap designed specifically for inserting the battery and electronics inside. The provided PCB and Arduino code are also included. The lamp is programmed to automatically turn on upon button press and stay lit for exactly one hour before switching off. It will then turn back on at the same time the following day. Both sides of the moon were printed separately and glued together using epoxy resin. Similarly, the battery holder and screw-in cap were bonded as well. UPDATE: The Arduino code has been revised to support an ON cycle ranging from one to four hours in duration.
