If you are a fan of Apple devices you might be interested in these new iCufflinks designed and created by Adafruit which have a subtle pulsating LED positioned behind their ‘on’ button symbols.
The iCufflinks are machined from finest 6 series aluminium and contains a tiny circuit board. Every within the iCufflinks is Open Source, from the source code, circuit board files, schematics to the CAD files which are all posted on GitHub
The iCufflinks are now available to buy from the Aadafruit website for $130. Adafruit also say on their website that a matching necklace is also being created and will be launching this summer.
