Adafruit have just released their iCufflinks—power button-style cufflinks that feature a pulsating light in time with the “sleep” light on a MacBook. Now you can feel its heartbeat even when you are on a date at a fancy restaurant. It’s a reminder that you can have only one true love. Plus, this way your MacBook won’t get jealous and pull some fatal attraction thing on you—holding all of your sensitive data for ransom and whatnot.
And the best part is that circuitry is completely open source if you would like to add your own customizations.
Check out the video after the break to see the iCufflinks in action.
