Since directly wiring the LEDs to the lan cards didn’t exactly work as planned I created a little ‘device’ that plugs into the parallel port. This is mostly just a prototype and cost about $5 to make with Radioshack parts. I didn’t want to spend the mondo cash on getting ‘cool’ white/blue/violet LEDs… a single white one costs as much as I paid for everything to build this!

I’m still working out the actual software to drive it. The original bit of software would only light up two LEDs, for eth0 TX & RX, but since I have both eth0 and eth1 I needed something better. I think I found it, but just need to test it first.

Here’s an image of the front of the “blink-o-tron” and an image of my horrible soldering job on the back.
