LED Isolators for HDD LEDs

LED Isolator

LED Isolator

A while ago, I posted a design for a home-made circuit designed to connect multiple hard drive add-on cards (and the motherboard) to a single case LED.  I made a handful of these for the servers around here, and in the three years or so since then, I’ve yet to see anything similar.  It’s possible that nobody but me actually cares if their case light reflects drive activity across all their drives — then again, it’s also possible that the people who actually cared simply made their own.

On the off chance that anybody wants one, I went to the trouble of making some professional-looking boards.  More detail is available here.
