Adafruit ICufflinks

Sophisticated. Modern. Open Source. Gorgeously machined aluminum with a subtle pulsating LED. Perfect for Father's Day or for that geek who loves technology and needs to get dressed up for a special event. Welcome to the future!

This is a new type of product for Adafruit, aimed at creating wearable electronics that are subtle, fun to wear, and look classy. We started with cufflinks and now have a necklace version available too. The cufflinks are CNC machined from the finest 6 series aluminum for durability and beauty. The iCufflinks are a remarkable accessory.

Each iCufflink contains a circuit board with pulsating LED and battery. The "pulsing" is similar to the "breathing" LED pattern on many laptop and computer systems. The default pattern is reverse-engineered from the Apple "breathing" LED on Macs, MacBooks, iMacs, etc.

Cufflinks are completely open source. The source code, circuit board files, schematics, and CAD files are posted on GitHub. Mod and hack away! Cufflinks can be reprogrammed to any pattern you'd like!

Before your fancy event, just pop the battery in, screw the backing, and your iCufflinks will gently pulsate for up to 72 hours. Each order comes with 2 sets of batteries; simply replace them when the LED is too dim to see. Replacement batteries are also available.

Cufflinks are lovingly machined in Toronto, Canada by Ross + Doell, and assembled in New York, USA. Created by Mike Doell, Limor Fried, and Phillip Torrone.
