Controlling my Nissan Leaf's AC remotely with Google Glass
Similar to what I did with Android Wear, I built some software for Glass to allow me to voice activate my car's AC or heat on my way to the car. This allows me to hands-free get the car warm or cool on my walk from work to the parking garage.
It's basically a direct port from the Wear version, but the source code is on GitHub for those inclined.
Also, to address some comments from last time: since my Leaf is an EV, there's no engine to start, which means the car can't be stolen or cause carbon monoxide poisoning if left in an enclosed space.
