Moon Lamp

thingiverse

This version has an opening on the top with a screw-on cap to put the battery and electronics inside. The PCB I've made and the Arduino code is also provided. I made the lamp to automatically turn on with a button press and to stay on for an hour. It will then automatically switch off. I will switch on again on the same time next day. I printed the both sides of the moon separately and glued them together using epoxy. The battery holder and the screw in cap I glued together as well. UPDATE: Edited the Arduino code to support a ON cycle of 1-4 hours. Materials for the ELECTRONICS: • ATtiny85 Board or standalone SPO8 chip • DS3231 Real Time Clock Module for Arduino 3,3 V/5 V: https://de.aliexpress.com/item/32464558997.html • 18650 Battery • 1S charging module: https://de.aliexpress.com/item/4000143432891.html • 1W white LED and 100R Resistor • Tact button • Some SMD parts if you want to build my PCB.
