These iCufflinks are a blend of sophistication and modernity. Crafted from high - quality 6 - series aluminum through CNC machining, they're not only durable but also look incredibly beautiful. Each cufflink features a circuit board with a subtly pulsating LED, offering a unique and eye - catching accessory. The 'pulsing' pattern is reverse - engineered from the Apple 'breathing' LED on Mac products. They're completely open - source, with all source code, circuit board files, schematics, and CAD files available on GitHub, allowing you to customize and hack them as you like. Whether it's Father's Day or a special event, these cufflinks are perfect for tech - loving geeks. They come ready to go, just insert the battery, screw on the backing, and they'll pulsate for up to 72 hours. Each order includes 2 sets of batteries, and replacement batteries are also available. Designed and made in North America, they're machined in Toronto, Canada and assembled in New York, USA.
Using these iCufflinks is easy. Before your special event, simply pop the battery into the cufflink and screw on the backing. They'll start gently pulsating and will keep doing so for up to 72 hours. When the LED gets too dim, replace the battery. We sell replacement batteries, so you can always keep your cufflinks working. Since these cufflinks are open - source, you can reprogram them to show any pattern you like. Just head over to GitHub, get the source code and other files, and start customizing. As for maintenance, keep them away from water and excessive heat. Wipe them gently with a soft cloth if they get dirty. And remember, they're made from high - quality aluminum, so they're durable, but handle them with care to keep them looking their best.
