One nOOd can be powered from a single coin cell battery. This is the easiest way to get your lights up and running.
Take a look at the video at the head of this tutorial for step-by-step instructions.
Figure out which end of the nOOd is the + and which is the -.
Insert the + end into the SW hole and the - end into the Gnd hole in the battery case and solder into place. Be sure the switch is turned off, or the battery is removed, before soldering -- you never want to solder to a live circuit.
Use low-temperature melt hot glue to glue the nOOd into the wire channel on the back of the necklace. I found it easiest to find the middle of the nOOd and start there, placing that center point right at the top of the outermost channel and working inwards.
Add some glue to the back of the battery case and press it down as well.
Finish by pressing on the backing and adding a necklace cord. Now you're ready to restore the Heart of Te Fiti.
