On the hobby side, hopefully this is the year that I finish my autonomous cubicle defence turret. I have most of the parts already, I need to check how fast is a Raspberry Pi with OpenCV to track faces (yay auto-targeting!). I'm using an Arduino to control the servos, and still need to figure out what the weapon will be (I presume some sort of Nerf gun will be a good match). Anyway, I solemnly promise to try to post something meaningful this year.
