Hey thanks to both of you. Time to start soldering! I'll keep checking back to see this new, old circuit. I am actually a glass worker who has always had a facination with electronics. I've wanted to make some magic aquarium creatures...things that glow and pulsate. It's taken a couple years to learn the skills for the glass. Now it's time to work on the magic....breathe life into the little zombies! On this same path of pulsating light, and looking down the road a bit...how do you think this circuit would convert over to smt? I like the low part count, i just know i am going to want an even smaller package and less power in the long run. Any thoughts? ~Zac~

Awsome thank you very much! So, I'm assuming a polyester cap is the same thing as a mylar? The polyester is just the insulator correct? Another question...is it possible to modify this circuit so the fade time will vary randomly? With the addition of a couple more caps, or would you need to add something more like a 555 timer circuit? Thanks again!

Regarding the LED Pulser: http://www.electronics-lab.com/projects/motor_light/020/ C1 is a 1µF 63V Polyester Capacitor. Can someone tell me what makes this cap significant in terms of the material (polyester), and voltage? Does it need to be polyester? Why such a high voltage, can that vary significantly? Thanks! zac
