My home office and workshop are on an overlook on the only deep river gorge on the entire length of the Mississippi River.

I always have a ton of projects in mind. On my ToodleDo list, I divide projects into those I'm actively working on, those I'm not doing but believe I will do, and those that sound good, but who knows if I'll ever get to them.

I have a large standalone workshop on the back of my property where I prototype and build stuff. It's bright, roomy, and has a giant door so it's easy to bring projects in or out.

I specialize in science and history, with a special emphasis on including do-it-yourself projects in the mix. My dozen or so books have sold hundreds of thousands of copies. I'm also a contributing editor at Popular Science and at Make Magazine.

I work with a lot of different editors at different publishers and magazines and so on, and having a system of shared folders makes keeping track of things a snap.

When something good hits me, I'll use Siri to make a note so I don't forget.
