I also enjoy software development, video games, learning more about electronics, and wood working.
Like many of you I have more hobbies than I can afford and now adding in the blinky blinky!
Woodworking bit me in 7th grade and I've invested in the whole shop full of tools, gone off to classes for hand tools, and am pretty much in the final stretch of the big tools a few more upgrades and will be done for life for the machines.
From Wood magazine plans:




For the wife's older hobby, all from my head:

Something why wife saw in a magazine that I made her, the front is a mirror:

The moulding came from a local cabinet manufacturer surplus store, this was a mother-in-law present for her steins display obviously.

and for the sons knick knacks, out of American Beech with "tung oil" finish:

Photography was another big hit in my youth, used to take drives just to take photos while the wife to be slept in the car or on the road when we got to the destination! Close to D600 so all my old lenses can be used again, not that they are anything special.
Would love to learn to _really_ cook well, and my son wants to be a chef and can probably cook better than anyone in the immediate family at 14 already.
Electronics are on my list to learn in life, being able to do what RJ goes someday and understand and hack whatever it is I could come up with. Made a couple of things off plans on the internet to monitor my power meter at one time, fixed a few computer mainboards by replacing soldered components.
Computers and programming, some of the first money I made was selling assembly language programs to one of the computer magazines for Apple computers in the day. Haven't kept up all my skills but can read a few different languages and muck my way around. Even learned cobol in school for you old timers!
Current projects on that are home automation, ir transceiving to control lights and such with the home automation, a butt on the couch sensor to help with the lights. Soon to add detailed power monitoring.
Love to learn to weld sometime, yet another hobby to learn..
Square foot gardening, perennial flowers, greenhouse, bike riding, lots of video games (grew up with pong), fishing (have not bought a boat yet), watching 3d movies in the home theature, car stereo.. Yeah, more hobbies than I can afford!
It's sad when a long time co-worker retires and their only hobby was work. I could win the lottery today and be busier than ever!
