I am working on a "power failure" mod, and I am looking for a way to blink 10-20 different white leds at seemingly random intervals.  It doesn't matter if it is truly random or not.  These LEDs will need to blink independently from each other as well.  I was advised that some creative circuitry and a 4060 clock chip would work, but although I am handy with a soldering iron, I am not that experienced at things like resistors and such.  I can build it if someone can give me a diagram example.  

As I said, "power failure" is the look I am going for.  Thanks in advance.

sorry if im not catching on here, but can you explain a little more what a "power failure" look
actually looks like

Search for CMOS Counters.

The only example I can think of is Star Trek (I know...) This effect can be seen a lot in damaged ships.  Panels going on and off, blinking lights, sparks,etc.  Now, I don't want sparks shooting out (well, maybe....no)

I have looked at timer chips such as the 4060 and the 4777, but as I mentioned earlier, I am not very experienced at scratchbuilding circuits.  Maybe once I build my hard drive chaser I will understand a little better.  Heck, I had one of those RadioShack 100 in 1 electronics kits, and I never did figure out the the flip-flop chip was for.  :P

There are several types of flip flops, they are latches, in common words it's a memory.

And again, search for CMOS Counters.

A good site to get some free timers, latches etc. is www.ti.com you can get free samples.

Okay, I found the wiring schematics I needed, but now I need to figure out how to get between 6 and 9 volts wo the circuit.  I bought a connector for my PCB that fits a FDD power connector already, and hacked one out of a CD drive for the larger molex connector.  I know there is 5v and 12v built into the power supply, and the chip I use regulates itself.

Allan: you can get 7v by using the +12v in the molex as vcc and the +5v as ground.
12-5 = 7.

Actually, Winterstick made a semirandom blinking circuit here.

Sounds like a pretty interesting mod u're planning on there, I think that would look quite cool. You should probably put a few different colored LEDs in there as well to make it different...
