A Welcome Home robot

Noticed how you do the same things every single time you enter your home? What if that could be automated, based on Bluetooth?

The catch? It cost me a night of sleep, and I never used it after that.

A script running on my iMac would scan its surroundings for my phone's Bluetooth ID. When it found it, it created a Keynote presentation, started some music (based on my last.fm profile), and began reading my emails.

It worked great. Until at 3am, when my iMac started playing Kenny Rogers at a loud volume, with a voice over that read my latest emails. Turns out the Bluetooth connection in the bedroom was spotty enough for my iMac to think I was leaving and coming home.
