Carbon Filter Help

I know that i have seen a DIY activated carbon filter thread with pics and i cant seem to find it. I found a thread that links to some other forum but i cant see the pics. If anyone has a link to the thread or can tell me where i can find it, i would really appreciate it.

Thank You
