Network Activity Lights

post #1 of 5
Thread Starter 
I'm wondering how do the activity lights on a NIC work? Is there extra pins to control the LEDs?

I ask because I'm looking to wire up a front NIC activity light.

Thanks.

While researching your question I found this...

http://www.techieinspire.com/keyboar...work-activity/

Direct link - http://www.itsamples.com/network-lights.html

I'll try it and report back. Though, it's not what you're looking for I'll keep searching.

Edit: Right click and go to settings and check USB Keyboard mode. Wow it actually works. lol kinda neat. It did render my num lock useless. I thought it would've kept num lock on and just not show the light. I use numlock much more than caps lock though so I switched those in the settings. I never use scroll lock.

Edit 2: I bet you could modify the source code they give you to maybe send the signal to a bread board via usb. The real question would be how to wire up the bread board.

Edit 3: Wow a major problem with the way this works with the keyboard is that in windows 7 when you mouse over your taskbar icons and you have multiple windows up it will only display the window preview for a split second and then close it.

Wow that's pretty neat. I might use that on my own PC.

This little project is for a keyboard/headless server though. I was hoping to take the easy route and just solder on some wires to the NIC. I'm also making 8 LED lights for RAID HDD activity. Hopefully I can make it look decent.

Lol I found yet another problem with it. When the lights flash it's actually activating that feature, like I mentioned previously I switched the one to my caps lock. So when I was trying to type out something and I had some network action going on it would alternate from caps to not caps. I felt like I was 13 again WhEn pEoPLe uSEd tO WrITe lIkE ThIs oN AiM.

I remember seeing some network room hacks like what you're describing done on sites like www.hackaday.com and on www.instructables.com

Couldn't you just clip off the NIC's LED's and solder on some wire to extend them?

I wonder if you take a keyboard apart if the indicator lights are actually soldered onto the main board... If not it would be really easy to modify it to use that program I linked earlier. AND since you will be RDP'ing into the server I don't think it would interfere with things like caps lock or num lock.

I could, if my NIC used external LEDs. I have a wack of 10/100Mbps like this in the closet. But my Gbps card uses this...
