Xmas time is here again … and we at Lunifera continue our tradition of decorating our office with a remote-controlled Xmas tree. This year, we added another cool feature: snow!
The tree is equipped with an air blower that pushes tiny styrofoam balls up through the hollow trunk. At the top, the balls are pushed out sideways and snow back down for an extra winter effect.
As in the previous years, we use a Vaadin UI for the Xmas tree controller. Clicking buttons sends MQTT messages with the appropriate commands to the Raspberry Pi that performs them in the physical world.
For the video, we use another Raspberry Pi running the Motion webcam server. Let’s hope that our bandwidth can take it (and that the suspension of the angel does not jump from it’s guidance)!
Our tree can be found here — Feel free to toy around with it and spread the Xmas spirit 🙂
