i’m definitely enjoying the midi ghostbusters theme. lol. this is a pretty cool idea, would be better if it was synced with the song on loudspeakers, like those christmas light arrays that blow people’s minds.

At first glance I thought this read “shit powered pumpkins” and thought “FINALLY someone’s putting those damn kid’s vandalism to good use”….

Oh well..

That pumpkin looks like one of the cats from Azumanga Daioh.

Haha Jakob, I see what you did there with the black on black text at the end of your summary. As I said in the article, the mutton chops were a joke for my friends. I shaved off part of my beard and then cued up the Shaft music on my phone and walked into the kitchen. I assure you that right now, my face is devoid of all hair.

pics or its not true! just kidding… howd you do the flicker effect?

Posted at 1:33 pm on Oct 21st, 2009 by george

@george: The candle flicker effect is pretty simple. Move up and down in brightness by a random amount, but not too far. The following function writes an individual flicker effect to all the ShiftBrites in a chain. You just run the function as many times as you want; loop it forever to get neverending candle.

void runCandleFlicker() {

int flicker;

for (int j1 = 0; j1 1023) flicker = 1023;
if (flicker < 100) flicker = 100;

LEDChannels[j1][0] = flicker;
LEDChannels[j1][1] = flicker*2/3;
LEDChannels[j1][2] = 0;
}

WriteLEDArray();
delay(random(20,70));

}

Or at least that would have been the right code if the comments weren’t filtered. Here’s the unmangled version: http://pastebin.com/f49488d12
