Adafruit industries is quickly becoming one of my favorite resources for electronics and in particular for electronics related knowledge.
They also make stuff. Like these nifty LED cufflinks – iCufflinks – that they’ve just released. The LED inside pulses just like your mac’s sleep indicator, which they say is “reverse engineered.” I admire anybody who admits to reverse engineering Apple tech without worrying about Steve Jobs’ long arm of the lawyer…
Anyway they’re the first tasteful example of wearable electronics. Period.
