Nice device - Puck.js

Recently I have came across an article which mention this new small smart device like Raspberry Pi.

Puck.js - the ground-breaking bluetooth beacon

Puck.js is a low energy smart device which can be programmed wirelessly and comes pre-installed with JavaScript. It is both multi-functional and easy to use, with a custom circuit board, the latest Nordic chip, Bluetooth Smart, Infra-red and much more, all enclosed in a tiny silicone case.
