Hey all. I'm working on a mod and I want some LEDs that flicker with HDD activity. How do I go about doing this? Past just plugging in a light to a molex connector I'm fairly ignorant about all this so just laying down a good place to start for me would be appreciated - for example, do I need to connect it somehow to the mobo pin that I would plug my case's LED into? I'm just a little lost. Thanks in advance.

Your exactly right--the header pin for the HDD activity light on on the motherboard is where you would attach it. Keep in mind this header supplies only about 2.1 volts, so if you want something blingy, go with ultrabright LED's or anything over 6000mcD. Also keep in mind the pos and neg leads when attaching the LED to the mobo. :D

Thanks for the reply. Believe it or not I just picked up your Maximum PC book today. I've got a load of ideas and it's definitely helping me fill in the holes. Just wished I had paid attention to those electronics lessons during physics... that's the only thing throwing me off at this point. Just nervous about shorting sumpin' out. Anyway thanks again.

I would say use 4N25 IC chip to protect your Mobo & HDD.

here is a like of some information that someone else has done on this.

This is the same idea on using the 4n25 IC to protect your Mobo, but they tool the HD activity off the mobo headers for this one.

If you want weird, you could always get one of these:

And btw, the price is in AUD. I've always wanted to put on of these into my case!
