That's an awesome project! I got mine in January, cost around the same. It's currently running as a portable git/file server but I've been looking for a more hands-on project for it. I'm not really in need of a garage door system, but your post was quite cool to read. :)
I think it may be a problem with the link itself. In the past I've seen SO links that auto scroll to the answer of interest, however this one just loaded to the top of the page.
