1.2 ComponentsExtree is a small, desktop sized, Christmas tree that can be programmed. It’s intended as a third channel feedback device (e.g., make it blink when you get an email), as well as an educational tool. It’s circuit is as simple as it gets: two components, an Arduino Pro Mini and an Adafruit Neopixel Ring, connected with three wires (VCC, GND, DATA). All structural parts can be produced on a laser-cutter, and it connects to the computer using an FTDI cable.

I’ve written a hackish Arduino sketch and Mono based client for it. All that, including the drawings as Autodesk Inventor source and DXF, can be found on Github.
