Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

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.

Why choose Puck.js?

Bluetooth Smart (or Bluetooth Low Energy) is an amazing technology - it's now built into virtually all Phones and Computers, and Bluetooth Smart devices have a battery life of years.

Most manufacturers conveniently gloss over the difficulties of programming their hardware, and other beacons are provided without software or left crippled by their boring factory-installed software. Puck.js is different - it comes with our Open Source JavaScript interpreter Espruino pre-installed, which makes it incredibly easy to use and means you can get started in just seconds, without any prior programming experience.
