Need to make very loooong lasting battery operated Mini LED light for backlit painting
I need to make a simple machine for part of an art project. I need to have two small LED lights placed one each on the tip of two clock hands . I need the lit clock hands to be battery operated ( looong as possible) and flattish ( maybe an inch in depth at most for entire piece) so it can hide behind a painting. Would like it to operate lit up and moving in clockwise circle nonstop day and night for at least a year .
What # volt? How to make simple clock ( besides just buying a kit? It only needs a very long hour hand with bulbs on each end ( say 12 oclock and 6 oclock) Where to get small ( 1/8 to 1/4" diameter) long lasting LED bulbs? As I said before, I am an absolute amateur here!
