Thanks for reminding me of that. I wondered how that would look as well.
Which brings up another question!
What kind of LEDs should I use? The Darlington Array can handle up to 500mA per LED. I could grab some generic "bright" white LEDs that say they are around 1000mcd, or I could go for a 1W smd LED on the little round pcb for each pumpkin, or I could get the neat RGB LEDs that come with an onboard communications chip.
As for color, white is fine for this year. In the future I'd like to tailor the color to more match a candle, but not yet. So mostly it's just an issue of brightness and angle of illumination. If I get normal LEDs, I'll probably have to diffuse the narrow output. It looks like some smd LEDs have a wider dispersion that might not need to be further diffused? Since I'm buying 6 of them, I'd prefer to keep the cost below $5 each or so.
Does anyone have experience on how much LED output is needed to light up the average pumpkin??
