Just completed the first phase of a personal project, Beamtest.com. My main goal in putting it together was to have a place for local homebrew electronics hackers to gather, and then from there, collaborate.
As with any endeavor, who knows if it grows into anything beyond a 1-user forum, which is where it is right now.
There is nothing unique or cutting edge about this site. It's basically a forum with a different facade. So far it has only 2 sections, the forum and the news postings. Baked with CakePHP.
