When your gadgets go to sleep, they tend to pulse peacefully. LEDs programmed to a soothing “breathing” waveform are to thank. You may ask yourself, why can’t my cufflinks do the same?

A new open source hardware project of Phil Torrone’s at Adafruit, the iCufflinks consist of a custom-machined aluminum power button, a simple circuit board programmed to pulse organically (a product of some clever reverse engineering), and a battery, which is good for 24 hours of elegance.

In true open-source form, you can download everything from the aluminum schematics to the code that controls the LED from GitHub. My question to Phil, or any other coders out there–when can I attach these to a chest sensor to match my own breathing? While I dream of electric sheep?

They’re $189 and available from:
