thoughts on LED circuit for art project

[shapeshifter]

all,

my skills with digital ciruits are quite limited, or more acurately
nonexistent , so am seeking your thoughts on the viability of the following
circuit idea and possibly a pointer to someone who can help me build it.

the goal is to create something of a starfield. im thinking N number of led
clusters each containing M leds. for immediate practicality, probably 4 or 5
clusters with 10-20 leds per. each cluster will pulsate, slowly turning on
and off (ideally with adjustable pulse rate) either all-at-once or perhaps
randomly within the cluster and after some time (variable?) will stop
firing and trigger the firing of the next cluster (the next cluster chosen
either in some predetermined sequence or perhaps randomly chosen). all leds
will be a single color, probably blue or violet. power is from a portable,
ie, battery, source.

if i had a schematic i could build it and im wondering if there is something
already out there or if not if you can point me to someone who could custom
design this. btw, this is for a non-commerical art project, so resources are
limited.

any thoughts? is this too complex for a beginner?


thanks for your thoughts.

My thoughts?

Hmmm...

I wonder why you don't start your sentences with capital letters and
punctuate conventionally when you're asking for help from whom, as far
as you know, are a bunch of folks who use conventional American
English to communicate.

For that matter, why even bother to identify yourself? You use lower
case for _everything_, which seems to indicate that you think of
yourself as an infinite sink, which certainly means that anything you
get will be sucked into your maw without the slightest thanks or
credit given to any source when you display what you'll tout as "your"
lower case works.

Hi,

Since this kind of thing has been done many times, you should look
around with Google to see how it has been done. Mostly today, it will
use a microcontroller, usually a PIC. This means you need to learn to
program to get this to work.

The good news is, its a very simple program.
