Yes, all you need is 2 resistors a cap and a 555, about six inches of wire and a breadboard.

I can post the schematic if needed.

Want a great effect, use the 555 pulse to clock a TTL (74193) counter, followed by a 74154 decoder and sequence the LEDs .

The simple addition of a flip flop to that can make the LEDs sequence back and forth like the front of "Night Rider's" K.I.T. (The car)

Or if you prefer a cylon eye.


The circuit on the far left (8 pin IC) is a 555 pulse generator.

catching up on posts, had to take my son to the emergency room today, he slammed his thumb in the truck door.

He will lose a nail, but otherwise he's fine. Thanks for asking.

10 year olds are resilient.

Same thing happened to my little finger when I was 6 or something, also lost the nail. But it grew back!

It was very gory, it has a little mark left today lol.
