Let's see... when work isn't keeping me busy:
- Aquariums, for anyone who read the novel I posted on the Aquarium post. There's something calming about it - plus the science behind the water, and the fish themselves I find fascinating.
- Computers. Recently built a nice work from home station. Rebuilt a laptop with a SSD and hooked it into three screens, plus an old mac i refurbished and hooked into the other HDMI input in the main monitor. So all I have to do is flip the source on the main monitor and switch keyboards and BOOM instant change from a PC to a Mac. Plus i've hooked 6 TB of external space into it as a movie home server and for all my photos. which leads into my next hobby.
- Photography. I got a GoPro for Christmas a couple of years back and things began snowballing after that. Now I have the GoPro, DSLR (Nikon D3300) and a Drone (which I'll get into in a bit).
- Travel. My girlfriend and I have been dating for a couple years now and we've made it a point to travel to world together. She is Peruvian so we have been to Peru once (and are going again for Christmas) and recently visited Thailand in April. We have a deal where we take a trip every year and we rotate who gets to pick the destination and then we plan it together. I'm up to suggestions for the next trip!
- Drones. My buddy convinced a few months back to buy a really nice Drone (DJI Phantom 3) and it is really awesome. Ties back into photography but the thing is more of a tool then a toy. The video you get from it is fantastic as the camera gimble moves independently to the drone itself. So no matter what the conditions you get beautiful 2.7k video. Plus the thing flies high. I mean REALLY high. I've maxed it out around 1700 feet.
- Home Theater. I have a pretty sophisticated set up at home and am continuously improving it. I have the TV hooked into a 7.1 surround sound, with all of the inputs hooked through the pass through HDMI (apple TV, Xbox One, Blueray) and have set up a home server for the movies. So basically the mac i have is set up as a shared desktop computer / dedicated server. I utilize a VPN to download any and all movies I want and am able to stream them via the Air Video app to the Apple TV.
- Video Games. I keep buying old systems off Ebay in attempt to fashion my future man cave. So at some point in the future I will have a library set up to play all the games i loved growing up as a kid. Right now we're up to N64, Xbox One, Xbox 360, Game Cube, Sega Genesis, Wii, PS1 and PS2. Been really into the Assassins Creed series recently.
Oh yes, and UConn Basketball.
