We have introduced the world’s open source electronic cufflinks, but if that friend you want to send gift is a girl, apparently the open-source wearable electronic pendant iNecklace will be more suitable.
Same as iCufflinks, iNecklace is designed by Adafruit Industries, and as we can see from the images, the open source electronic necklace features a unique Apple power button design. Inside, the gorgeously machined aluminum pendant has a circuit board and a subtle pulsating LED powered by two CR1220 batteries. When activated, iNecklace will gently pulsate for up to 72 hours. And the open source feature allows you to customize iNecklace’s LED light. The open source wearable electronic pendant is CNC machined from the finest 6 series aluminum for durability and fashion. Apart from that, the LED pendant is on a 18-inch sterling silver 1.6mm diamond-cut curb chain treated to inhibit tarnishing.
iNecklace open source wearable electronic pendant is priced at $74.99 USD. If you’re interested, jump to ThinkGeek for more details or check out the following demo video first.
