# William Osman

> William Osman is an American engineer turned YouTuber whose channel turned a homemade 80-watt laser cutter into a comedy career. He builds absurd machines, films the result, and somewhere between a ham-and-cheese Vin Diesel and a backyard X-ray rig has become one of the loudest voices in the modern maker movement. In 2023 he co-founded Open Sauce, a creator-driven STEM convention that has since grown to more than 33,000 attendees.
