OK, I've been playing with 555 and 556 circuits, PWM, etc. to pulse LEDs. I figured out how to do "comet trails" using capacitors, but am having trouble getting this stepped pulsing effect (see ? below).
My current theory is to use a 555 w/ capacitor to pulse the LED with comet trails, and a second 555 w/ transistor to "chop up" the comet trail from the first 555.
Working on a diagram/breadboarding at the moment, so any help is appreciated.
And yes, I have read LEDs, 555s, PWM, Flashers, and Light Chasers.
