Click to viewChad Barraford has designed a "digital life assistant" who recognizes him, cooks hot dogs, and alerts his friends when he has a migraine. Unlike Tony Stark's J.A.R.V.I.S. though, this one only cost $691.98 to build.

While Chad proudly shows off his creation on his website, he's definitely not sharing the code that runs it all. So if you want your very own Iron Man style migraine alert system, you'll have to build it from scratch. [Boston]
