Random flashing LED's?

post #1 of 9
Thread Starter 
I want to find some "dancing" or random flash LED's (or make some myself) for an upcoming case mod. The end result will be that they randomly flash with hard drive activity and will plug into the HDDLED header on the motherboard. Anyone know how I could do this? Is it as simple as wiring some LED's off of a pigtail? What about getting random flash patterns with multiple colors?

the HDD activity header is really only on or off (decent bit of load or not currently spun up)... it would be rather difficult to get elaborate dancing lights when your output is only a 1 or 0... I guess it's possible to have them light up based on how LONG the output is a 1, but it would be quite difficult to have anything that looked impressive without having SOME background in electronic engineering

Perhaps invest into some more Tracers and sound activated LEDs instead?

Tracers suck. these are being discarded as soon as I buy a 4gb kit

But thats basically the effect I wanted. Like tracers, but brighter and more colors

If you know a bit about circuitry, you probably could rig something up using a 555 timer or two.

You could build a circuit using your HDD LED header as a pseudo random number generator (PRNG). The circuit would control your LEDs and flash them based on an internal clock. The HDD LED signal would alter the signalling.

Hey I didn't even think about that! Might have been because I was incredibly caffeinated when I wrote my first post...

You could actually use two 555 timers and have a few of the inputs inverted (different inverted inputs on each timer) so that you don't get the same output each time... then just add in a couple different colored LEDs as outputs and you're set!

You can find those parts (555 timers, LEDs, 330ohm resistors, and an IC with inverters) at any online electronics components shop... I can't really think of any since I don't dabble much in electronics

There are several good electronics suppliers listed in the Modding Supply thread
