Activity LED Mod

Does anyone know of a kit or something that uses the hard drive activity light to drive a series of more than one LED or perhaps a cathode light... I want my case to freakin light like crazy when my IDE activty light usually goes on... I mean... I want to light my case... but I don't want it to just be "lit up" if you know what I mean... I want the whole world to know that my computer is processing... does anyone know if something like this exists?

Thanks!

Hehe! OK Guy!

hope your not epileptic

Hey, cut the guy some slack!

This is just an extension of some the case mods that are already taking place.

I haven't seen anything that does what you are seeking so my personal advice regarding this would be as follows:

As not hard drives have headers available that output the drive activity, tapping into the led would be problematic at best. While soldering directly where the LED already are is possible, it would need to be redone whenever the hard drive is changed, and if done wrong the hard drive can be killed!

I think the best solutions would be to tap into the hard drive LED from the motherboard, us an optical sensor to see the actual hard drive LED go on and create a pulse based on that, or make a little program that monitors activity in Windows and sends data to the parallel port that can be used for your lighting system.

Tapping into the hard drive acitvity light from the motherboard shouldn't be so difficult. There is already a two pin header to connect to so the signal can be routed to a little patch board to amplify the signal and then use it to power additional lights.

If you know someone who does little projects I am sure they can build a little board that has a light sensor that can be tuned to the brightness of the led so that it can sense when it is on and then provide power to some other lamp. (The tuning part is a resister, but finding a light sensor that work specifically with an LED may be a bit of trial an error. I have NEVER used a light sensor to sense anything other than sunlight, or normal lamp light.)

The final solution would be to make a little board that plugs into the parallel port of your computer. (After all, what do you use that for anymore anyway?)

NOTE: The ASP portion doesn't let this link show up right away. Click on the "I/O Ports Uncensored"... link and you're good to go.

Make a little board, make a little program, and you're good to go!

I hope that helps,
