Chronoduino an expandable Arduino watch

orcinus posted pictures of the Chronoduino expandable Arduino watch in the project log forum:

So i’ve set out to design the ultimate Arduino watch platform that’s also usable as an ultra-miniature sensor node and dubbed it (quite unimaginatively) – Chronoduino. Some parts are based off of Bazile Romaine’s rev 3 MakerBot Watch, some are completely new. The board itself was routed by hand, from scratch.
