My Christmas tree

Video of it in action
(sorry for bad lighting but you get my point

)

I think I made that a few years ago, made it again this year, got some fakeish plastic Christmas tree-like cone and a battery-powered set of lights at the dollar store, put those together, wired where the batteries would be to my TI C2000 Launchpad (because my brother has my Arduino), fired up the Fade example in Energia and there you go, a programmable USB Christmas tree. Still have to figure out how to serial port with Energia, but had I have my Arduino, could have done some fancy blinking stuff with it. Not that I already can do fancy stuff.

Are you doing some Christmas-themed projects this year?

that looks really nice

But I'm note sure if I'm supposed to stare at the tree or that huge mouth x.x

sadly I have no tech-related projects this year for christmas ._.

I remember this juju and this was kinda cool. WOuld be interesting to see if this was possible with a larger tree and with different stuff, eg my music

Some people do that with their entire house decorations.

there is a guy near me that every year sets up lights over the entirety of his yard / house and has it set to music with patterns and whatnot.

Wow, that sounds annoying haha.

And you never sneaked over and pulled the plug...? It would even be a good thing as you prevent a massive waste of energy

It's January 15th and I still have my tree plugged in. Hehehe.

The power bill must be insane with so many lights. I wonder how much it would be with LED lights, though?

I have yet to remove my christmas decorations lol, because I was sick two weeks ago, which was around when I originally planned to remove them, and then I got too busy

But again, in Quebec City there is a neighborhood in which they even let the Christmas lights turned ON until April or so (or at least until there's no snow anymore).

Fun fact: Christmas tree is now powered by my Raspberry Pi.

Code (node.js) Select

var wpi = require('wiring-pi');
wpi.wiringPiSetup();
wpi.pinMode(1, wpi.PWM_OUTPUT);
var dir = 1;
var val = 511;
function sweep()
{
  if(val <= 0 || val >= 1023)
    dir *= -1;
  val += dir;
  wpi.pwmWrite(1, val);
}

setInterval(sweep, 3);
