Early Life and Education

William Osman was born on June 8, 1991, in California, United States, to parents referred to as Mr. Osman and Mrs. Osman.

He might have had siblings but details about them are unknown.

He attended Foothill Technology High School in Ventura, where he created short skits and early videos with his best friend and future collaborator, John Willner, including a Stirling Engine for the 2009 California State Science Fair.

Osman later earned a Bachelor of Science in mechanical engineering from California State University, Northridge, in 2014.

He is of white ethnicity, though his religion is not publicly known.

Career

William Osman kicked off his content creation in high school, filming homemade skits and experiments with his friend John Willner, but he didn’t launch his official YouTube channel until November 25, 2013.

Early videos centered on his DIY laser cutter, the “RetinaSmelter9000,” which he used for quirky tests like slicing ice, blending engineering demos with comedic flair that quickly built a niche following among maker enthusiasts.

By 2016, after marrying Chelsea and balancing a full-time engineering job, he ramped up uploads, drawing from his professional background in MRI tech and military gear to infuse authenticity into his builds, while his high school collaborations with Willner evolved into polished productions that hooked viewers with “dubious quality, questionable integrity, and unethical delivery.”

Osman’s rise accelerated in the late 2010s with viral sensations that showcased his boundary-pushing creativity, most notably the 2017 viewer-requested video sculpting a Vin Diesel bust from 90 laser-cut slices of ham and cheese, designed in Autodesk Maya and Fusion 360, which exploded online and solidified his reputation for absurd yet technically impressive feats.

He followed with Thanksgiving specials like a “gravy train” delivery system and turkey laser-cutter in 2017, then collaborated with Simone Giertz in 2018 to mod her Comuta-Car into a giant computer mouse, expanding his network among STEM YouTubers.

Tragedy struck that December when the Thomas Fire destroyed his home, but a GoFundMe raised over $120,000 in hours, turning vulnerability into community strength and inspiring future content on resilience.

William Osman continues to innovate through high-profile collabs, like powering a car with lemon batteries alongside Mark Rober, and ambitious projects such as a 2021 homemade X-ray machine that highlighted safety boundaries while educating on radiation tech.

In 2023, he founded Open Sauce, a San Francisco-based maker convention blending Maker Faire and VidCon vibes to unite 75 top STEM influencers, while his secondary channel offers behind-the-scenes glimpses into unboxings and quick experiments.

With over 153 videos amassing billions of views, he hosts the Safety Third podcast and partners with organizations like the Navy for egg-drop challenges aboard the USS Theodore Roosevelt, cementing his legacy as a hilarious yet insightful voice in engineering education and online creativity.
