[Coco] COCO Robot update.

Something like http://home.comcast.net/~pumpkin1000/props/eyes.htm using a 
pair of 555 timers might work.

You might also check toward the bottom of 
http://www.horrorseek.com/home/halloween/wolfstone/HalloweenTech/anemak_MakingLEDEyes.html 
for various blinking eyes, flashing eyes, and fading eyes circuits for other 
ideas.

Subject: [Coco] COCO Robot update.

Coco powered robot has stalled. I have the mobile base going, head is almost 
done and basic frame good.


I have some led eyes, does anyone know a simple circuit to ramdonly blink 
them?


I may use a basic stamp for this but it seems like overkill. Just want to 
randomly blink the led eyes off then
back on again. A stand alone animation that will operate independanty of the 
coco I suppose.


I should say I don't want a stanard blinking rate, I want the blinks to 
vary. A turn signal flasher won't do.


If I have to I'll use the basic stamp... But seems there must be a simpler 
way I'm not thinking of.


Any thoughts?

All ears,


Steven
