The iNecklace is a gorgeously machined aluminum pendant with a subtle pulsating LED. Perfect for the playa or with Prada. Made for women who celebrate art, science, engineering and great design. Proudly made in North America (Canada and USA).
iNecklace completely open source. The source code, circuit board files, schematics and CAD files are posted on GitHub. Mod & Hack away!
