In true DIT spirit, this book was made possible thanks to the love, support, and generosity of dozens of people.

I’m eternally grateful to the team at Make, who gave this project a chance: Dale Dougherty, Gareth Branwyn, Brian Jepson (my intrepid editor), Mark Fraunfelder, Sherry Huss, and everyone else. The team at TechShop that took me under their wing: Mark Hatch, Jim Newton, Dan Gonzalez, Zack Johnson; and all the makers mentioned in this book who put up with me, especially Tim Anderson.

Writing-wise, I never would have made it without the patience and encouragement of Ethan Watters, Jason Rezaian, Stephen Hanselman, and Julia Serebrinsky. And everyone who read drafts and provided such wonderful feedback: Malcolm Knapp, Abe Fetterman, and Mom!

Writing this book served as a constant reminder of how lucky I am to know and work with Eric Stackpole (and everyone else in the OpenROV community). What a crazy ride. I’m looking forward to the many more adventures to come.

And, of course, all 2,582 Kickstarter backers. Writing is a lonely battle, and their support was wind in the sails.
