Sound Reactive Hawaiian Lei from RobertG328 on Instructables
I wanted to make something fun for my daughters to wear to their school’s father daughter dance. It was Hawaiian Luau themed, so there was no better way to accessorize than with a sound reactive lei necklace!
I ended up making three necklaces all together – one for me, and one for each of my daughters. By the time I made the third necklace, I had the process down and could get one put together in a about 3 hours.
The process is basically removing the original string from necklace re-stranding it with with 3 wires (power, ground, and control, + mono cord) and soldering RGB LEDs in between each flower. The fabric flowers diffuse the light nicely for a very cool, very unique look.
I had a great time making the necklaces. My daughters enjoyed the process. They both gave me great ideas , helped me test and troubleshoot, and both learned quite a bit about electronics.
