A Smart Bluetooth Button that can be programmed wirelessly

Puck.js is an intelligent Bluetooth button. With the Espruino JavaScript interpreter on its internal ARM microcontroller, software can be uploaded, debugged and modified wirelessly from any modern computer or phone, making development of embedded devices significantly easier. It has built-in sensors, lights, infrared transmitter, GPIO, and can even control other Bluetooth LE devices.

This is version 2 of the popular Puck.js - with added accelerometer, gyro, FET, calibrated temperature sensor and improved Bluetooth signal strength!
