An electronic necklace for the techie woman

Although just an accessory, Adafruit’s iNecklace is an example of how electronics is entering our life in so many strange yet interesting ways. Made for women who celebrate art, science and technology, the pulsating necklace features a pulsing similar to the ‘breathing’ LED pattern on many laptop and computer systems. The default pattern is reverse-engineered from Apple’s ‘breathing’ LED on the Mac, MacBook and iMac.

The open twist: The iNecklace is CNC machined from fine aluminium, with a screw- in backing. The pendant contains a circuit board with pulsating LED and battery. A single battery can keep the device pulsing for over 72 hours. The iNecklace hardware is completely open source, so anybody can create their own accessory or gadget using the reverse- engineered pulsing technology. The source code, circuit board files, schematics and CAD files are posted on GitHub ( https:// github. com/ adafruit/ iNecklace).
