Oh, probably my biggest hobby of the past year has been First Person View Drone racing. Basically I've been building and programming the drone from scratch, and have started taking my maiden flights. No races yet, just due to the steep learning curve trying to fly it while staring at a small monitor. But it's been a fun, although expensive, hobby. And now that I have a flying (fast) drone, I realize all the mistakes I made in it's design, and need to build another one.
As a side byproduct hobby, I bought a 3D printer kit to make parts for the drone, so indirectly I've been into 3D printing too. I made myself some nice camera mounts, and get some good shots when I want to view the scenery. For the most part, I fly without a recording camera as it makes it sluggish, and I want to go fast.
Here's a shot of Boston I took from my parents house. This drone has no GPS, so flying it high is strictly done manually, and can be tricky on a windy day.
Neighbor wanted a pic of this, so up I went
But the drone isn't ideal for arial photography. That's the one I'm currently building with 6 motors and GPS.
