Our guest this week is David Lang. David Lang is an entrepreneur, writer, and National Geographic Fellow. In 2012, along with Eric Stackpole, he co-founded OpenROV to create a low-cost robot to explore an underwater cave. Since then, OpenROV has raised over $900,000 on Kickstarter and become one of the largest underwater drone manufacturers. The team also created OpenExplorer as a digital field journal to empower and connect citizen scientists and explorers. Lang is the author of Zero to Maker — part memoir and part guidebook for participating in the growing maker movement.
