The iNecklace is tasteful — and open source. This machined aluminum pendant with a subtle, pulsating LED can be hacked or modified.
The necklace pendant, by Adafruit, is CNC machined from the finest 6 series aluminum for durability and beauty, and has a "screw in backing" that allows easy access to the battery using a coin. Each pendant contains a circuit board with pulsating LED and battery. The pendant comes strung on a 18" long sterling silver 1.6mm diamond-cut curb chain that has been treated to inhibit tarnishing. The necklace is placed in a black velveteen box, ready to be given as a gift.
