Long story short:
I would like a basic circuit schematic that makes a few (4-8?) LED's blink at random intervals, i.e. some on, some off, some fast, some slow, etc.
Long story long:
I'm making a diorama (omgmiddleschoolalloveragain) and I'm adding LED's that I would like to blink at random intervals (to each other). They're supposed to be computers that have all gone haywire and need fixing (I wanted to add LED's and this is a pretty simple diorama so I'm gonna put little cardboard computers with LED's poking out of them). Each computer has a "different problem" which is why they need to blink randomly to each other, not randomly to time and in unison to each other. If that makes sense...
I know some basics about circuitry: Capacitors/resistance/ground/parallel-vs-series/etc. but I haven't made circuits since high-school so the simpler the better.
If that sounds like too much trouble I'm all ears on new ideas (or if it's WAY easier to do 3 or 4 different circuits altogether that just run 555 timers that have the battery connected at different times to start the blinking intervals, I'll just do that).
Please and thanks
p.s. here is a video of basically what I'm looking for
