Open Sauce, the engineering and maker convention that grew out of the YouTube creator community, returned to the San Mateo County Event Center for its second year in that venue — and it was noticeably larger than the year before. More exhibits filled more rooms, drawing both veteran exhibitors and first-timers who built projects specifically for the show. The event also confirmed its next edition: July 17–18, 2027, with tickets already on sale.
A Showcase of Mechanical Madness
Returning favorites included Battlebot teams, Project Empire, and Devising Delight — all familiar faces from previous years. But the 2026 edition also saw a wave of new projects. One team reportedly spent $9,000 turning a couch into a car. Yes, a drivable couch.
The Bay Area Droid Builders brought their stunningly realistic Star Wars replicas, including K-2SO, MSE-6, and B1 battle droids, roaming the convention floor. Just down the aisle, Bay Area Foam Tag set up an arena with dozens of blasters and what seemed like infinite darts — including one blaster taller than some of the players.
Hacker Dojo, one of Silicon Valley’s oldest hackerspaces, used the show to raise awareness about its ongoing space troubles. The dojo is in danger of losing its space, and staff gave away toy cars that kids could customize and take home. Supporters could also bid on a brick artwork that took years to create.
From Air Purifiers to Robot Soccer
Air quality is a growing concern, and maker Joel Hartlaub (aka JoelCreates) showed off his OddCube repairable air purifier kit. He launched a Kickstarter for the project, giving attendees a chance to breathe easier at home.
Dorian Todd, a Maker Faire Bay Area blue ribbon winner, brought Sesame, a tiny, affordable walking robot. The tabletop soccer match using the bots was a hit with visitors.
Whitcorp demonstrated a 3D photogrammetry dome and what the Make: team called “the most badass 3D printers” they’d ever seen. Meanwhile, a dedicated gaming hall featured indie video games and alt-ctrl creations. Bryan Racic built an open-source, 3D-printable nautical controller for seafaring games, demoing a not-crab fishing game called Klorbiest Catch where players dropped traps to collect “klorbs.”
Art, Insects, and the Human Scale
Artists Lexi Tayte and Jessica Crafternoon — known for giant Furby builds — constructed a giant housefly. The soft-material sculpture aimed to subvert the negative human reaction to insects by magnifying the form to human scale. Or, as the builders noted, maybe they just really like bugs.
Panels and Creator Conversations
Across two stages, YouTubers spoke about electronics, cosplay, and the ins and outs of the YouTube algorithm. Attendees learned which projects were born from rage, who spent $50,000 not to make a video, and the worst reason to start a channel now (money). For those determined to start anyway, the advice remained unchanged: make a ton of videos.
A Growing Tradition
Open Sauce was founded in 2023 by YouTuber William Osman as a STEM-focused convention. The first event at San Francisco’s Pier 35 drew over 10,000 attendees and 150 exhibitors. By 2024, it had more than doubled, moving to the Cow Palace in Daly City to accommodate 20,000+ attendees and 500 exhibitors. The event has been held at the San Mateo County Event Center since 2025.
What’s Next
The next Open Sauce is already scheduled for July 17–18, 2027 at the same San Mateo venue. General admission tickets are on sale now, with a 2-day pass priced at $216.75 including fees. An early bird discount code — earlyearlybird — takes 50% off GA tickets. More ticket types will be announced later. Under-4s and over-100s get in free with a ticket holder.
If you can’t wait that long, the Bay Area Maker Faire is coming up soon.
