I just put up a bit of info about my latest build, a VWCDPIC (Volkswagen auxiliary audio input adapter).  This is the second one I've built, this time based off the newer design with some improvements over my first one.

 I've also switched the forums over to require registration in order to post.   I don't mind having to delete a few spam posts a day, but since the Hack A Day rush, I've been dealing with more like 30-40 a day, so enough is enough.  All you have to do to post is sign up for an account and verify it - it's fast and easy.  Just use the "Register" button in the login form to the left.
