Programmable Christmas Tree is a JavaScript Interpreter

Here at Hackaday, we find Christmas time very exciting because it means an influx of holiday-themed hacks that really help us get into the festive mood. [Andrew’s] programmable Christmas tree hosted at HackMyXmas is certainly one of our favorites. The project consists of a 500 RGB LEDs wrapped around a typical Christmas tree and controlled by a Teensy.  However, not settling for the typical, simple and cyclical pattern for the LEDs, [Andrew] decided the tree had to be programmable of course! So, a single board computer (a C.H.I.P) running Linux was used to provide a Wifi connection and a web server to easily program the tree.

This is where things get very interesting. The C.H.I.P board hosts a comprehensive website that conveniently gives you the option to program the LEDs using either, Scratch like draggable blocks (using Googles Blockly) or even pure JavaScript. Once the perfect pattern is conceived, you can test run it on the online simulator or even send it off straight to the Tree, watching it blink in all its glory on the provided live stream.

We applaud [Andrew] mammoth effort for invoking programming in such a fun way! You can check out the live stream of [Andrew]’s Christmas tree below.
